    		<property name="minConnectionsPerPartition" value="5" />
    	</bean>
    
    </beans>

9、Spring事务的配置

10、SpringMVC的配置文件

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
    	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
    	xmlns:context="http://www.springframework.org/schema/context"
    	xmlns:mvc="http://www.springframework.org/schema/mvc"
    	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
            http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd
            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
    
    	
    	<mvc:annotation-driven />
    
    	
    	<context:component-scan base-package="cn.itcast.user.controller" />
    
    	
    	<bean
    		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    		<property name="prefix" value="/WEB-INF/views/" />
    		<property name="suffix" value=".jsp" />
    	</bean>
    
    </beans>

**对于，controller的注解扫描，应该配置在SpringMVC的配置文件里面。**

11、Mybatis与Spring的整合

11.1 整合文件

11.2  Mybatis的全局配置文件

<?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>

12、涉及到的页面

13、UserMapper.java和UserMapper.xml的实现

13.1 UserMapper.java

import java.util.List;
    import cn.itcast.user.pojo.QueryInfo;
    import cn.itcast.user.pojo.User;
    
    public interface UserMapper {
    
    	public List<User> queryUserList();
    
    	public List<User> queryUserPageInfo(QueryInfo queryInfo);
    
    	public int queryUserCount();
    }

13.2 UserMapper.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.user.mapper.UserMapper">
    
    	<select id="queryUserList" resultType="user">
    		SELECT * FROM tb_user
    	</select>
    	<select id="queryUserPageInfo" parameterType="queryInfo"
    		resultType="user">
    		SELECT * FROM tb_user
    		limit #{start},#{rows}
    	</select>
    	<select id="queryUserCount" resultType="int">
    		SELECT count(*) FROM
    		tb_user
    	</select>
    </mapper>

14、UserController的实现

import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.bind.annotation.RequestParam;
    import org.springframework.web.bind.annotation.ResponseBody;
    
    import cn.itcast.user.bean.EasyUIResult;
    import cn.itcast.user.pojo.QueryInfo;
    import cn.itcast.user.service.UserService;
    
    @RequestMapping("user")
    @Controller
    public class UserController {
    
    	@Autowired
    	private UserService userService;
    
    	@RequestMapping(value = "list", method = RequestMethod.GET)
    	public String toUsersPage() {
    		return "users";
    	}
    
    	@RequestMapping(value = "data/list", method = RequestMethod.GET)
    	@ResponseBody
    	public EasyUIResult queryUserList(
    			@RequestParam(value = "page", defaultValue = "1") Integer page,
    			@RequestParam(value = "rows", defaultValue = "5") Integer rows) {
    		QueryInfo queryInfo = new QueryInfo(page, rows);
    
    		return this.userService.queryUserList(queryInfo);
    	}
    
    }
