SSM框架整合，以CRM为例子
Mybatis、SpringMVC练习
CRM系统
- 回顾
Springmvc 高级参数绑定 数组 List
<input type name=ids /> 多个
方法 (Integer[] ids) QueryVo (里面Integer[] ids)
方法（QueryVo 里面List<Items> itemList
<input type name=itemList[${s.index}].name />
- 2. REquestMapping 处理器映射器（找此标签 路径 ）
Value = http://www.mamicode.com/{多个路径,}
Value = http://www.mamicode.com/{/item/sfdsf.action} 类头上
Method=RequestMethod.POST或GET
3、 Controller方法返回值
三个
ModelAndView 建议不使用 不解偶
String 返回视图的路径 （形参 绑定Model ） 重定向redirect:另一个方法的映射路径 forward:内部转发
Void 异步请求使用
- 异常处理器
预期、运行时
自定义异常处理类 实现HandlerEexceptionResolver
由Spring实现化 自定义的处理类
未知异常
CustomEexception 继承Eexception
4、 上传图片
1）Form 上传图片了 action上传路径
2）input type=file name=picturePic
3)接收此图片 形参上绑定 MultipartFile picturePic 接口
4）配置此接口的实现类 Springmvc.xml配置CommonsMultipartFileResolver id=multipartFileResolver
5、JSON数据交互
应用场景：前端是各种 html Freemarker JSP一个Servlet 是Java代码 jstl C
浏览器 Ajax 发送JSON字符串 报文
6、拦截器
拦截器 应用 （练习）

创建crm数据库，执行sql
效果如下图：
3. 工程搭建
使用的Bootstrap前端框架,官方网站
http://www.bootcss.com/
工程使用Springmvc、spring、mybatis框架整合完成。
3.1. 需要的jar包
- spring（包括springmvc）
- mybatis
- mybatis-spring整合包
- 数据库驱动
- 第三方连接池。
- Json依赖包Jackson
jar包位置如下图：
3.2. 整合思路
Dao层：
1、SqlMapConfig.xml，空文件即可，但是需要文件头。
2、applicationContext-dao.xml
a) 数据库连接Druid
b) SqlSessionFactory对象，需要spring和mybatis整合包下的。
c) 配置mapper文件扫描器。Mapper动态代理开发 增强版
Service层：
1、applicationContext-service.xml包扫描器，扫描@service注解的类。
2、applicationContext-trans.xml配置事务。
Controller层：
1、Springmvc.xml
a) 包扫描器，扫描@Controller注解的类。
b) 配置注解驱动
c) 配置视图解析器
Web.xml文件：
1、配置spring监听器
2、配置前端控制器。
3.3. 创建工程
创建动态web工程，步骤如下图：
创建boot-crm，如下图
3.4. 加入jar包
加入资料中的jar包
3.5. 加入配置文件
创建config资源文件夹，在里面创建mybatis和spring文件夹
3.5.1. SqlMapConfig.xml
空文件即可
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" 3 "http://mybatis.org/dtd/mybatis-3-config.dtd"> 4 <configuration> 5 6 7 8 </configuration>
3.5.2. applicationContext-dao.xml

4.2. 页面显示问题
访问页面，发现不能正常显示
打开开发者工具，选择Network，
发现css、js等资源文件无法加载
原因：web.xml配置时，是设置所有的请求都进入SpringMVC。但是SpringMVC 无法处理css、js等静态资源，所以无法正常显示
解决方案：
1. 在springmvc.xml中配置
1 <!-- 解决静态资源无法被springMVC处理的问题 --> 2 <mvc:default-servlet-handler />
2. 修改web.xml，让所有以action结尾的请求都进入SpringMVC
1 <servlet-mapping> 2 <servlet-name>boot-crm</servlet-name> 3 <!-- 所有的请求都进入springMVC --> 4 <url-pattern>*.action</url-pattern> 5 </servlet-mapping>
解决后的效果如下图，可以正常显示页面样式：
我们使用第二种方式解决，因为此项目中的页面的请求都是以action结尾的，所以使用第二种方式，在web.xml里面进行相应的配置
1 <servlet-mapping> 2 <servlet-name>boot-crm</servlet-name> 3 <!-- 所有以action结尾的请求都进入springMVC --> 4 <url-pattern>*.action</url-pattern> 5 </servlet-mapping>
5. 实现查询条件初始化
5.1. 需求分析
页面效果如上图，在查询客户的时候，可以选择客户来源,所属行业,客户级别信息,页面加载时需要初始化查询条件下拉列表。
前端jsp逻辑
1 <form class="form-inline" action="${pageContext.request.contextPath }/customer/list.action" method="get"> 2 <div class="form-group"> 3 <label for="customerName">客户名称</label> 4 <input type="text" class="form-control" id="customerName" value="${custName }" name="custName"> 5 </div> 6 <div class="form-group"> 7 <label for="customerFrom">客户来源</label> 8 <select class="form-control" id="customerFrom" placeholder="客户来源" name="custSource"> 9 <option value="">--请选择--</option> 10 <c:forEach items="${fromType}" var="item"> 11 <option value="${item.dict_id}"<c:if test="${item.dict_id == custSource}"> selected</c:if>>${item.dict_item_name }</option> 12 </c:forEach> 13 </select> 14 </div> 15 <div class="form-group"> 16 <label for="custIndustry">所属行业</label> 17 <select class="form-control" id="custIndustry" name="custIndustry"> 18 <option value="">--请选择--</option> 19 <c:forEach items="${industryType}" var="item"> 20 <option value="${item.dict_id}"<c:if test="${item.dict_id == custIndustry}"> selected</c:if>>${item.dict_item_name }</option> 21 </c:forEach> 22 </select> 23 </div> 24 <div class="form-group"> 25 <label for="custLevel">客户级别</label> 26 <select class="form-control" id="custLevel" name="custLevel"> 27 <option value="">--请选择--</option> 28 <c:forEach items="${levelType}" var="item"> 29 <option value="${item.dict_id}"<c:if test="${item.dict_id == custLevel}"> selected</c:if>>${item.dict_item_name }</option> 30 </c:forEach> 31 </select> 32 </div> 33 <button type="submit" class="btn btn-primary">查询</button> 34 </form>
按照jsp的要求,把对应的数据查询出来,放到模型中。
数据存放在base_dict表，可以使用dict_type_code类别代码进行查询
使用需要获取的数据如下图：
使用的sql:
SELECT * FROM base_dict WHERE dict_type_code = ‘001‘
5.2. 实现DAO开发
5.2.1. pojo
因为页面显示的名字是下划线方式，和数据库表列名一样，根据页面的样式，编写pojo
1 public class BaseDict { 2 private String dict_id; 3 private String dict_type_code; 4 private String dict_type_name; 5 private String dict_item_name; 6 private String dict_item_code; 7 private Integer dict_sort; 8 private String dict_enable; 9 private String dict_memo; 10 get/set方法自己实现 11 }
5.2.2. Mapper
编写BaseDictMapper
1 public interface BaseDictMapper { 2 /** 3 * 根据类别代码查询数据 4 * 5 * @param dictTypeCode 6 * @return 7 */ 8 List<BaseDict> queryBaseDictByDictTypeCode(String dictTypeCode); 9 10 }
5.2.3. Mapper.xml
编写BaseDictMapper.xml
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE mapper 3 PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" 4 "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> 5 <mapper namespace="cn.itcast.crm.mapper.BaseDictMapper"> 6 7 <!-- 根据类别代码查询数据 --> 8 <select id="queryBaseDictByDictTypeCode" parameterType="String" 9 resultType="cn.itcast.crm.pojo.BaseDict"> 10 SELECT * FROM base_dict WHERE dict_type_code = 11 #{dict_type_code} 12 </select> 13 14 </mapper>
5.3. 实现Service开发
5.3.1. BaseDictService 接口
1 public interface BaseDictService { 2 3 /** 4 * 根据类别代码查询 5 * 6 * @param dictTypeCode 7 * @return 8 */ 9 List<BaseDict> queryBaseDictByDictTypeCode(String dictTypeCode); 10 }
5.3.2. BaseDictServiceImpl 实现类
1 @Service 2 public class BaseDictServiceImpl implements BaseDictService { 3 4 @Autowired 5 private BaseDictMapper baseDictMapper; 6 7 @Override 8 public List<BaseDict> queryBaseDictByDictTypeCode(String dictTypeCode) { 9 10 List<BaseDict> list = this.baseDictMapper.queryBaseDictByDictTypeCode(dictTypeCode); 11 return list; 12 } 13 }
5.4. 实现Controller开发
5.4.1. 修改之前编写的controller
1 @Controller 2 @RequestMapping("customer") 3 public class CustomerController { 4 5 @Autowired 6 private BaseDictService baseDictService; 7 8 /** 9 * 显示客户列表 10 * 11 * @return 12 */ 13 @RequestMapping("list") 14 public String queryCustomerList(Model model) { 15 // 客户来源 16 List<BaseDict> fromType = this.baseDictService.queryBaseDictByDictTypeCode("002"); 17 // 所属行业 18 List<BaseDict> industryType = this.baseDictService.queryBaseDictByDictTypeCode("001"); 19 // 客户级别 20 List<BaseDict> levelType = this.baseDictService.queryBaseDictByDictTypeCode("006"); 21 22 // 把前端页面需要显示的数据放到模型中 23 model.addAttribute("fromType", fromType); 24 model.addAttribute("industryType", industryType); 25 model.addAttribute("levelType", levelType); 26 27 return "customer"; 28 } 29 }
5.4.2. 效果
实现效果如下图：
5.4.3. 硬编码问题
这里是根据dict_type_code类别代码查询数据，这里的查询条件是写死的，有硬编码问题。可以把类别代码提取到配置文件中，再使用@value注解进行加载。
5.4.3.1. 添加env.properties
添加env.properties配置文件
#客户来源 CUSTOMER_FROM_TYPE=002 #客户行业 CUSTOMER_INDUSTRY_TYPE=001 #客户级别 CUSTOMER_LEVEL_TYPE=006
5.4.3.2. 修改springmvc.xml配置文件
在springmvc.xml中加载env.properties
1 <!-- 加载controller需要的配置信息 --> 2 <context:property-placeholder location="classpath:env.properties" />
注意:Controller需要的配置文件信息必须添加到springmvc的配置文件中
5.4.3.3. 修改Controller方法
1 @Controller 2 @RequestMapping("customer") 3 public class CustomerController { 4 5 // 客户来源 6 @Value("${CUSTOMER_FROM_TYPE}") 7 private String CUSTOMER_FROM_TYPE; 8 // 客户行业 9 @Value("${CUSTOMER_INDUSTRY_TYPE}") 10 private String CUSTOMER_INDUSTRY_TYPE; 11 // 客户级别 12 @Value("${CUSTOMER_LEVEL_TYPE}") 13 private String CUSTOMER_LEVEL_TYPE; 14 15 @Autowired 16 private BaseDictService baseDictService; 17 18 /** 19 * 显示客户列表 20 * 21 * @return 22 */ 23 @RequestMapping("list") 24 public String queryCustomerList(Model model) { 25 // 客户来源 26 List<BaseDict> fromType = this.baseDictService.queryBaseDictByDictTypeCode(this.CUSTOMER_FROM_TYPE); 27 // 所属行业 28 List<BaseDict> industryType = this.baseDictService.queryBaseDictByDictTypeCode(this.CUSTOMER_INDUSTRY_TYPE); 29 // 客户级别 30 List<BaseDict> levelType = this.baseDictService.queryBaseDictByDictTypeCode(this.CUSTOMER_LEVEL_TYPE); 31 32 // 把前端页面需要显示的数据放到模型中 33 model.addAttribute("fromType", fromType); 34 model.addAttribute("industryType", industryType); 35 model.addAttribute("levelType", levelType); 36 37 return "customer"; 38 } 39 40 }
6. 客户列表展示
6.1. 需求
展示客户列表，并且可以根据查询条件过滤查询结果，并且实现分页。
效果如下图：
页面代码：
1 <div class="panel-heading">客户信息列表</div> 2 <!-- /.panel-heading --> 3 <table class="table table-bordered table-striped"> 4 <thead> 5 <tr> 6 <th>ID</th> 7 <th>客户名称</th> 8 <th>客户来源</th> 9 <th>客户所属行业</th> 10 <th>客户级别</th> 11 <th>固定电话</th> 12 <th>手机</th> 13 <th>操作</th> 14 </tr> 15 </thead> 16 <tbody> 17 <c:forEach items="${page.rows}" var="row"> 18 <tr> 19 <td>${row.cust_id}</td> 20 <td>${row.cust_name}</td> 21 <td>${row.cust_source}</td> 22 <td>${row.cust_industry}</td> 23 <td>${row.cust_level}</td> 24 <td>${row.cust_phone}</td> 25 <td>${row.cust_mobile}</td> 26 <td> 27 <a href="#" class="btn btn-primary btn-xs" data-toggle="modal" data-target="#customerEditDialog" onclick="editCustomer(${row.cust_id})">修改</a> 28 <a href="#" class="btn btn-danger btn-xs" onclick="deleteCustomer(${row.cust_id})">删除</a> 29 </td> 30 </tr> 31 </c:forEach> 32 </tbody> 33 </table>
分析我们需要根据四个条件进行查询，返回数据是分页对象Page
Sql语句:
1 SELECT 2 a.cust_id, 3 a.cust_name, 4 a.cust_user_id, 5 a.cust_create_id, 6 b.dict_item_name cust_source, 7 c.dict_item_name cust_industry, 8 d.dict_item_name cust_level, 9 a.cust_linkman, 10 a.cust_phone, 11 a.cust_mobile, 12 a.cust_zipcode, 13 a.cust_address, 14 a.cust_createtime 15 FROM 16 customer a 17 LEFT JOIN base_dict b ON a.cust_source = b.dict_id 18 LEFT JOIN base_dict c ON a.cust_industry = c.dict_id 19 LEFT JOIN base_dict d ON a.cust_level = d.dict_id 20 WHERE 21 a.cust_name LIKE ‘%马%‘ 22 AND a.cust_source = ‘6‘ 23 AND a.cust_industry = ‘2‘ 24 AND a.cust_level = ‘22‘ 25 LIMIT 0, 10
6.2. 创建pojo开发
public class Customer { private Long cust_id; private String cust_name; private Long cust_user_id; private Long cust_create_id; private String cust_source; private String cust_industry; private String cust_level; private String cust_linkman; private String cust_phone; private String cust_mobile; private String cust_zipcode; private String cust_address; private Date cust_createtime; get/set。。。。。。 }
6.3. 实现DAO
分析：
1. 前台发起请求,需要接收请求过来的查询条件数据，可以使用pojo接收数据。需要依此编写查询逻辑。
2. 前台需要分页显示，根据准备好的分页实现，应该返回分页类Page，而创建Page分页类需要数据总条数，所以也需要查询数据总条数的逻辑。
根据分析，DAO需要编写两个方法:
1. 需要根据条件分页查询客户信息
2. 需要根据条件查询数据总条数
6.3.1. 创建QueryVo
需要编写QueryVo，里面包含查询条件属性和分页数据。
创建接受请求参数的QueryVo：
public class QueryVo { private String custName; private String custSource; private String custIndustry; private String custLevel; // 当前页码数 private Integer page = 1; // 数据库从哪一条数据开始查 private Integer start; // 每页显示数据条数 private Integer rows = 10; get/set。。。。。。 }
6.3.2. Mapper
创建CustomerMapper 接口
public interface CustomerMapper { /** * 根据queryVo分页查询数据 * * @param queryVo * @return */ List<Customer> queryCustomerByQueryVo(QueryVo queryVo); /** * 根据queryVo查询数据条数 * * @param queryVo * @return */ int queryCountByQueryVo(QueryVo queryVo); }
6.3.3. Mapper.xml
创建CustomerMapper.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="cn.itcast.crm.mapper.CustomerMapper"> <sql id="customerQueryVo"> <where> <if test="custName != null and custName != ‘‘"> AND a.cust_name LIKE ‘%${custName}%‘ </if> <if test="custSource != null and custSource != ‘‘"> AND a.cust_source = #{custSource} </if> <if test="custIndustry != null and custIndustry != ‘‘"> AND a.cust_industry = #{custIndustry} </if> <if test="custLevel != null and custLevel != ‘‘"> AND a.cust_level = #{custLevel} </if> </where> </sql> <!-- 根据queryVo分页查询数据 --> <select id="queryCustomerByQueryVo" parameterType="cn.itcast.crm.pojo.QueryVo" resultType="cn.itcast.crm.pojo.Customer"> SELECT a.cust_id, a.cust_name, a.cust_user_id, a.cust_create_id, b.dict_item_name cust_source, c.dict_item_name cust_industry, d.dict_item_name cust_level, a.cust_linkman, a.cust_phone, a.cust_mobile, a.cust_zipcode, a.cust_address, a.cust_createtime FROM customer a LEFT JOIN base_dict b ON a.cust_source = b.dict_id LEFT JOIN base_dict c ON a.cust_industry = c.dict_id LEFT JOIN base_dict d ON a.cust_level = d.dict_id <include refid="customerQueryVo" /> <if test="start != null"> LIMIT #{start}, #{rows} </if> </select> <!-- 根据queryVo查询数据条数 --> <select id="queryCountByQueryVo" parameterType="cn.itcast.crm.pojo.QueryVo" resultType="int"> SELECT count(1) FROM customer a <include refid="customerQueryVo" /> </select> </mapper>
6.4. 实现service
6.4.1. 接口
编写接口CustomerService
public interface CustomerService { /** * 根据条件分页查询客户 * * @param queryVo * @return */ Page<Customer> queryCustomerByQueryVo(QueryVo queryVo); }
6.4.2. 实现类
编写接口实现类CustomerServiceImpl
@Service public class CustomerServiceImpl implements CustomerService { @Autowired private CustomerMapper customerMapper; @Override public Page<Customer> queryCustomerByQueryVo(QueryVo queryVo) { // 设置查询条件,从哪一条数据开始查 queryVo.setStart((queryVo.getPage() - 1) * queryVo.getRows()); // 查询数据结果集 List<Customer> list = this.customerMapper.queryCustomerByQueryVo(queryVo); // 查询到的数据总条数 int total = this.customerMapper.queryCountByQueryVo(queryVo); // 封装返回的page对象 Page<Customer> page = new Page<>(total, queryVo.getPage(), queryVo.getRows(), list); return page; } }
6.5. 实现Controller
改造Controller的方法
@RequestMapping("list")
public String queryCustomerList(QueryVo queryVo, Model model) {
try {
// 解决get请求乱码问题
if (StringUtils.isNotBlank(queryVo.getCustName())) {
queryVo.setCustName(new String(queryVo.getCustName().getBytes("ISO-8859-1"), "UTF-8"));
}
} catch (Exception e) {
e.printStackTrace();
}
// 客户来源
List<BaseDict> fromType = this.baseDictService.queryBaseDictByDictTypeCode(this.CUSTOMER_FROM_TYPE);
// 所属行业
List<BaseDict> industryType = this.baseDictService.queryBaseDictByDictTypeCode(this.CUSTOMER_INDUSTRY_TYPE);
// 客户级别
List<BaseDict> levelType = this.baseDictService.queryBaseDictByDictTypeCode(this.CUSTOMER_LEVEL_TYPE);
// 把前端页面需要显示的数据放到模型中
model.addAttribute("fromType", fromType);
model.addAttribute("industryType", industryType);
model.addAttribute("levelType", levelType);
// 分页查询数据
Page<Customer> page = this.customerService.queryCustomerByQueryVo(queryVo);
// 把分页查询的结果放到模型中
model.addAttribute("page", page);
// 数据回显
model.addAttribute("custName", queryVo.getCustName());
model.addAttribute("custSource", queryVo.getCustSource());
model.addAttribute("custIndustry", queryVo.getCustIndustry());
model.addAttribute("custLevel", queryVo.getCustLevel());
return "customer";
}
7. 修改客户信息
7.1. 需求
页面效果如下图：
1、客户列表中点击“修改”按钮弹出客户信息修改窗，并初始化客户信息
2、点击“保存修改”按钮将修改后的结果保存到数据库中
7.2. 实现编辑数据回显
在客户列表显示中，可以点击修改按钮，弹出修改界面，打开浏览器的开发者工具，发现当点击修改按钮，会发起一个请求
如下图方式进行查看
分析这里应该是发起请求到后台，获取该用户的详细信息，在页面上可以回显
复制请求路径中的edit.action，在customer.jsp页面中搜索，找到请求逻辑
找到的代码如下图：
发现这里是一个Ajax请求，根据这个请求我们可以开发后台逻辑，提供给前端页面进行调用
7.3. 回显功能实现
7.3.1. Mapper接口
在CustomerMapper添加方法
/** * 根据id查询客户 * * @param id * @return */ Customer queryCustomerById(Long id);
7.3.2. Mapper.xml
在CustomerMapper.xml编写sql
<!-- 根据id查询用户 --> <select id="queryCustomerById" resultType="cn.itcast.crm.pojo.Customer"> SELECT * FROM customer WHERE cust_id = #{id} </select>
7.3.3. Service接口
编写CustomerService.接口方法
/** * 根据id查询数据 * * @param id * @return */ Customer queryCustomerById(Long id);
7.3.4. Service接口实现类
在CustomerServiceImpl实现接口方法
@Override public Customer queryCustomerById(Long id) { Customer customer = this.customerMapper.queryCustomerById(id); return customer; }
7.3.5. Controller
在CustomerController编写方法
/** * 根据id查询用户,返回json格式数据 * * @param id * @return */ @RequestMapping("edit") @ResponseBody public Customer queryCustomerById(Long id) { Customer customer = this.customerService.queryCustomerById(id); return customer; }
7.4. 实现编辑客户数据
在编辑框，点击保存修改按钮，应该进行数据保存，如下图所示：
发起请求如下图：
在页面找到的请求逻辑是：
function updateCustomer() { $.post("<%=basePath%>customer/update.action",$("#edit_customer_form").serialize(),function(data){ alert("客户信息更新成功！"); window.location.reload(); }); }
7.5. 编辑功能实现
7.5.1. Mapper接口
在CustomerMapper添加方法
/** * 根据id编辑客户 * * @param customer */ void updateCustomerById(Customer customer);
7.5.2. Mapper.xml
在CustomerMapper.xml编写sql
<select id="updateCustomerById" parameterType="cn.itcast.crm.pojo.Customer"> UPDATE `customer` SET <if test="cust_name !=null and cust_name != ‘‘"> `cust_name` = #{cust_name}, </if> <if test="cust_user_id !=null"> `cust_user_id` = #{cust_user_id}, </if> <if test="cust_create_id !=null"> `cust_create_id` = #{cust_create_id}, </if> <if test="cust_source !=null and cust_source != ‘‘"> `cust_source` = #{cust_source}, </if> <if test="cust_industry !=null and cust_industry != ‘‘"> `cust_industry` = #{cust_industry}, </if> <if test="cust_level !=null and cust_level != ‘‘"> `cust_level` = #{cust_level}, </if> <if test="cust_linkman !=null and cust_linkman != ‘‘"> `cust_linkman` = #{cust_linkman}, </if> <if test="cust_phone !=null and cust_phone != ‘‘"> `cust_phone` = #{cust_phone}, </if> <if test="cust_mobile !=null and cust_mobile != ‘‘"> `cust_mobile` = #{cust_mobile}, </if> <if test="cust_zipcode !=null and cust_zipcode != ‘‘"> `cust_zipcode` = #{cust_zipcode}, </if> <if test="cust_address !=null and cust_address != ‘‘"> `cust_address` = #{cust_address}, </if> `cust_createtime` = NOW() WHERE (`cust_id` = #{cust_id}); </select>
7.5.3. Service接口
编写CustomerService.接口方法
/**
* 根据id编辑客户数据
*
* @param customer
*/
void updateCustomerById(Customer customer);
7.5.4. Service接口实现类
在CustomerServiceImpl实现接口方法
@Override public void updateCustomerById(Customer customer) { this.customerMapper.updateCustomerById(customer); }
7.5.5. Controller
在CustomerController编写方法
需要正确的响应，要告诉前端更新成功。返回值有没有都可以。
这里需要加@ResponseBody注解，使其不走视图解析器。
/** * 根据id查询用户,返回更新后客户的json格式数据 * * @param id * @return */ @RequestMapping("update") @ResponseBody public String updateCustomerById(Customer customer) { Customer result = this.customerService.updateCustomerById(customer); return "OK"; }
8. 删除客户
8.1. 需求分析
点击客户列表中的删除按钮，提示“警告信息”，如下图
如下图，点击确定后删除用户信息，并刷新页面。
发起的请求如下图：
搜索前端jsp页面逻辑找到如下代码：
function deleteCustomer(id) { if(confirm(‘确实要删除该客户吗?‘)) { $.post("<%=basePath%>customer/delete.action",{"id":id},function(data){ alert("客户删除更新成功！"); window.location.reload(); }); } }
8.2. 功能开发
8.2.1. Mapper接口
在CustomerMapper添加方法
/** * 根据id删除用户 * * @param id */ void deleteCustomerById(Long id);
8.2.2. Mapper.xml
在CustomerMapper.xml编写sql
<!-- 根据id删除客户 --> <delete id="deleteCustomerById" parameterType="long"> DELETE FROM customer WHERE cust_id = #{id} </delete>
8.2.3. Service接口
在CustomerService编写接口方法
/** * 根据id删除客户 * * @param id */ void deleteCustomerById(Long id);
8.2.4. Service实现类
在CustomerServiceImpl实现接口方法
@Override public void deleteCustomerById(Long id) { this.customerMapper.deleteCustomerById(id); }
8.2.5. Controller
在CustomerController编写方法
/** * 删除用户 * * @param id * @return */ @RequestMapping("delete") @ResponseBody public String deleteCustomerById(Long id) { this.customerService.deleteCustomerById(id); return "ok"; }
