5，ssm框架整合

5.1，整合思路

SqlMapConfig.xml：spring整合mybatis需要引入SqlMapConfig.xml，里面可以没有实质性的内容，但是必须保留文件头。

applicationContext-dao.xml：由spring创建数据库连接池，管理SqlSessionFactory、mapper代理对象。

applicationContext-service.xml：所有service对象交由spring容器管理

applicationContext-trans.xml：由spring来管理实务

springmvc.xml:引入springmvc，由spring来管理controller

web.xml:加载spring容器，加载springmvc

5.2,SqlMapConfig.xml

在e3-manager-web/src/main/resources/目录下创建三个文件夹conf、spring、mybatis

在mybatis目录下创建SqlMapConfig.xml文件，文件内容如下：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration></configuration>

6，开发一个小的查询功能

6.1,需求描述

浏览器输入http://localhost:8080/e3-manager-web/item/536563能查到对应的商品信息

6.2，创建实体类

创建cn.e3mall.pojo包：

</mapper>

6.4,接口

创建cn.e3mall.service包：

ItemService.java

package cn.e3mall.service;import cn.e3mall.pojo.TbItem;public interface ItemService {TbItem getItemById(long itemId);
}

6.5,service

创建cn.e3mall.service.impl包

ItemServiceImpl.java

package cn.e3mall.service.impl;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;import cn.e3mall.mapper.TbItemMapper;
import cn.e3mall.pojo.TbItem;
import cn.e3mall.pojo.TbItemExample;
import cn.e3mall.pojo.TbItemExample.Criteria;
import cn.e3mall.service.ItemService;/*** 商品管理Service* <p>Title: ItemServiceImpl</p>* <p>Description: </p>* <p>Company: www.itcast.cn</p> * @version 1.0*/
@Service
public class ItemServiceImpl implements ItemService {@Autowiredprivate TbItemMapper itemMapper;@Overridepublic TbItem getItemById(long itemId) {//根据主键查询//TbItem tbItem = itemMapper.selectByPrimaryKey(itemId);TbItemExample example = new TbItemExample();Criteria criteria = example.createCriteria();//设置查询条件criteria.andIdEqualTo(itemId);//执行查询List<TbItem> list = itemMapper.selectByExample(example);if (list != null && list.size() > 0) {return list.get(0);}return null;}}

6.6，controller

创建cn.e3mall.controller目录

ItemController.java

package cn.e3mall.controller;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;import cn.e3mall.pojo.TbItem;
import cn.e3mall.service.ItemService;/*** 商品管理Controller* <p>Title: ItemController</p>* <p>Description: </p>* <p>Company: www.itcast.cn</p> * @version 1.0*/
@Controller
public class ItemController {@Autowiredprivate ItemService itemService;@RequestMapping("/item/{itemId}")@ResponseBodypublic TbItem getItemById(@PathVariable Long itemId) {TbItem tbItem = itemService.getItemById(itemId);return tbItem;}
}

6.7,解决mapper绑定异常的问题

在pom.xml文件的project节点内添加

<!-- 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>

7,部署并且启动应用

选中e3-manager,右键，Run As -》 Maven Build

输入clean tomcat7:run

打开浏览器，访问http://localhost:8080/e3-manager-web/item/536563
