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:jarwarpom

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

Maven3.3.3Eclipse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 pom工程中,配置tomcat插件。启动的端口号,和工程名称。

taotao-managerpom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-parenttaotao-common安装到本地仓库。然后再启动。

 

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springmybatis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

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、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

使用逆向工程生成的代码。

 

3.4 Service

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:TbItemjson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-daopom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。 -->
