第一章，阿里的Dubbo完美初级搭建，待续。。。
1.1 后台工程搭建分析
Web工程。
Maven的常见打包方式：jar、war、pom
Pom工程一般都是父工程，管理jar包的版本、maven插件的版本、统一的依赖管理。聚合工程。
Taotao-parent：父工程，打包方式pom，管理jar包的版本号。
| 项目中所有工程都应该继承父工程。
|--Taotao-comm：通用的工具类通用的pojo。打包方式jar
|--Taotao-manager：后台工程。聚合工程。Pom工程
|--taotao-manager-dao：打包方式jar
|--taotao-manager-pojo：打包方式jar
|--taotao-manager-service：打包方式：jar
|--taotao-manager-web：打包方式war
1.2 工程搭建
1.2.1 Taotao-parent
Pom工程。
开发环境：eclipse mars
Maven：3.3.3Eclipse自带。
本地仓库：默认位置在~/.m2/repository
Eclipse不需要配置，只需要把本地仓库放到当前用户目录下的.m2下。

1.3 启动工程
启动taotao-manager工程。
需要在taotao-manager 的pom工程中，配置tomcat插件。启动的端口号，和工程名称。
在taotao-manager的pom文件中添加如下配置：
<!-- 配置tomcat插件 --> <build> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <configuration> <port>8080</port> <path>/</path> </configuration> </plugin> </plugins> </build> |
启动tomcat插件：
clean tomcat7:run
先把taotao-parent、taotao-common安装到本地仓库。然后再启动。
2 框架整合
Ssm框架
Springmvc
Spring
Mybatis
2.1 整合的思路
Dao层：
1、SqlMapConfig.xml，空文件即可。需要文件头。
2、applicationContext-dao.xml。
a) 数据库连接池
b) SqlSessionFactory对象，需要spring和mybatis整合包下的。
c) 配置mapper文件扫描器。
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。
表现层：
Springmvc.xml
1、包扫描器，扫描@Controller注解的类。
2、配置注解驱动。
3、视图解析器
配置文件保存的工程：taotao-manager-web
2.2 SqlMapConfig.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration>
</configuration> |
2.3 db.properties

3 整合测试
3.1 需求
根据商品id查询商品信息。响应一个json数据。
3.2 功能分析
数据库：mysql，要求版本是5.6
查询的表：tb_item
根据商品id查询对应商品信息。
Mybatis的逆向工程：
请求的url：/item/{itemId}
业务逻辑：
1、从url中取参数@PathVariable
2、根据商品id查询商品信息。得到一个TbItem对象
3、直接响应TbItem对象，需要使用@ResponseBody
返回值：TbItem
3.3 Dao层
使用逆向工程生成的代码。
3.4 Service层
参数：商品id
业务逻辑：调用Mapper代理对象， 根据商品id查询商品信息。
返回值：TbItem
@Service public class ItemServiceImpl implements ItemService {
@Autowired private TbItemMapper itemMapper;
@Override public TbItem getItemById(long itemId) { //根据商品id查询商品信息 //TbItem tbItem = itemMapper.selectByPrimaryKey(itemId); TbItemExample example = new TbItemExample(); //设置查询条件 Criteria criteria = example.createCriteria(); criteria.andIdEqualTo(itemId); List<TbItem> list = itemMapper.selectByExample(example); if (list != null && list.size() > 0) { TbItem item = list.get(0); return item; } return null; }
} |
3.5 表现层
请求的url：/item/{itemId}
参数：Long itemId
返回值：TbItem（json数据，需要使用@ResponseBody）
@Controller public class ItemController {
@Autowired private ItemService itemService;
@RequestMapping("/item/{itemId}") @ResponseBody public TbItem getItemById(@PathVariable Long itemId) { TbItem tbItem = itemService.getItemById(itemId); return tbItem; } } |
需要配置taotao-manager-dao的pom文件：
添加一个资源拷贝的配置。
<!-- 如果不添加此节点mybatis的mapper.xml文件都会被漏掉。 --> <build> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> <filtering>false</filtering> </resource> </resources> </build> |
