**************************
配置mabatis接口代理开发
*接口名和映射文件必须同名
*在同一个包下
*输入值，返回值都必须对应
*映射文件namespace必须和接口的全路径类名想同
**************************************************************************************************************************************************
1.创建项目 命名
2.导入jar包
3.进入web.xml 进行相关配置
1）字符集的配置
<!-- 用过滤器 设置编码类型为utf-8 -->
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
2）加载spring配置文件
<!--加载spring配置文件-->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 设置配置文件位置 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
3）加载springmvc配置文件
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 设置springmvc配置文件位置 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:springmvc.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
4.创建applicationcontext.xml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:mvc="http://www.springframework.org/schema/mvc"

http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">
<!-- 扫描器 -->
<context:component-scan base-package="cn.itcast"/>
<!-- 配置连接池: -->
<!-- 引入外部属性文件 -->
<!-- 配置C3P0连接池: -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="com.mysql.jdbc.Driver"/>
<property name="jdbcUrl" value="jdbc:mysql:///shop"/>
<property name="user" value="root"/>
<property name="password" value="1234"/>
</bean>
<!-- 创建sqlsessionfactory-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 指定mybatis的全局配置文件的路径 -->
<property name="configLocation" value="classpath:sqlmapconfig.xml"></property>
<!-- 数据源 -->
<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- 配置mabatis接口代理开发
*接口名和映射文件必须同名
*在同一个包下

*映射文件namespace必须和接口的全路径类名想同
-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="cn.itcast.dao"></property>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean>
<!-- 事务管理: -->
<!-- 事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"/>
</bean>
<!-- 开启注解事务 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>
5创建springmvc.xml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:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">
<!-- 扫描器：扫描该包或者该包子包下的所有带有某些注解的类，建立一个bean -->
<context:component-scan base-package="cn.itcast"/>
<!-- 默认创建注解处理器映射器和处理器适配器，还提供了json数据格式的支持 -->
<mvc:annotation-driven/>
<!-- 配置视图解析器 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsps/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
</beans>
6 粘贴jdbc.property文件(可有可无)
7创建sqlmapconfig.xml 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>
8.创建*mapper.xml文件
<?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.dao.UserMapper">
<select id="find" resultType="cn.itcast.domain.User">
select * from adminuser
</select>
</mapper>
9.创建*mapper.java文件
package cn.itcast.dao;
import java.util.List;
import cn.itcast.domain.User;
public interface UserMapper {
public List<User> find();
}
10 创建控制类
package cn.itcast.controller;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import cn.itcast.domain.User;
import cn.itcast.service.UserService;
@Controller
@RequestMapping("/user")
public class UserController {
@Resource
private UserService userService;
@RequestMapping("/showUser")
public void toIndex(){
List<User> users = this.userService.find();
System.out.println(users);
}
}
11创建service
package cn.itcast.service;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import cn.itcast.dao.UserMapper;
import cn.itcast.domain.User;
@Service
public class UserService {
@Resource
UserMapper userdao;
public List<User> find(){
return userdao.find();
}
}
