< 二 > 数据库基本配置文件

　　jdbc.url=jdbc:mysql://localhost:3306/test?characterEncoding=utf8&useSSL=true
　　jdbc.class=com.mysql.jdbc.Driver
　　jdbc.user=root
　　jdbc.word=920619

< 三 > 配置 Mybatis ( mybatis.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>
    
    <settings>
    
        <!-- 配置使用 JDBC 驱动获取自增长主键 -->
        <setting name="useGeneratedKeys" value="true"/>
        
        <!-- 配置使用列别名替换列名, 默认为TRUE -->
        <setting name="useColumnLabel" value="true"/>

        <setting name="mapUnderscoreToCamelCase" value="true"/>
        
    </settings>
    
</configuration>

< 四 > DAO 接口

package dao;

import java.util.List;
import java.util.Map;

import model.User;

public interface UserDao {
    
    List<Map<String, Object>> selectAllUser();
    
    Integer insertUser(User user);
    
}

< 五 > DAO 对应的 Mapper 配置文件

<?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="dao.UserDao">

    <select id="selectAllUser" resultType="model.User">
        SELECT * FROM user
    </select>
    
    <insert id="insertUser" parameterType="model.User"  keyProperty="userId" >
        INSERT INTO user ( user_name, user_sex ) 
        VALUES ( #{userName}, #{userSex} )    
    </insert>
    
</mapper>

< 六 > 整合 SPRING + MYBATIS

<?xml version="1.0" encoding="UTF-8"?>
<beans 
    xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-4.1.xsd"
>

    <!-- 加载数据路配置信息 -->
    <context:property-placeholder location="classpath:jdbc.properties"/>
    
    <!-- 配置 C3P0 数据源 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="driverClass" value="${jdbc.class}"/>
        <property name="user" value="${jdbc.user}"/>
        <property name="password" value="${jdbc.word}"/>
        <property name="maxPoolSize" value="30"/>
        <property name="minPoolSize" value="10"/>
        <property name="autoCommitOnClose" value="false"/>
        <property name="checkoutTimeout" value="1000"/>
        <property name="acquireIncrement" value="2"/>
    </bean> 
    
    <!-- 配置 MYBATIS SQL SESSION 工厂 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="configLocation" value="classpath:mybatis.xml"/>
        <property name="typeAliasesPackage" value="model"/>
        <property name="mapperLocations" value="classpath:mapper/*.xml"></property>
    </bean>
    
    <!-- 配置自动扫描的 DAO 包, 被动态实现注入到 IOC 容器 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <property name="basePackage" value="dao"/>
    </bean>
    
</beans>

< 七 > 测试 SPRING + MYBATIS 的整合

package test;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import dao.UserDao;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring-mybatis.xml"})
public class Test01 {
    
    @Autowired
    private UserDao userDao;
    
    @Test
    public void test() {
        System.out.println(userDao.selectAllUser());
    }
    
}

< 八 > 配置 业务层 事务

<?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:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-4.1.xsd
    http://www.springframework.org/schema/tx 
    http://www.springframework.org/schema/tx/spring-tx-4.1.xsd"
>

    <!-- 配置自动扫描的包 -->
    <context:component-scan base-package="service"></context:component-scan>
    
    <!-- 配置事物管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    
    <!-- 开启事物注解配置 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>
    
</beans>

< 九 > service 例子 ( 接口和实现类 )

package service.inter;

import java.util.List;
import java.util.Map;

import model.User;

public interface UserService {
    
    public List<Map<String, Object>> selectAllUser(User user);
    
}
package service.imple;

import java.util.List;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import dao.UserDao;
import model.User;
import service.inter.UserService;

@Service
public class UserImple implements UserService {

    @Autowired
    private UserDao userDao;

    @Override
    @Transactional //标志为事物
    public List<Map<String, Object>> selectAllUser(User user) {
        userDao.insertUser(user);
//        System.out.println(1 / 0);
        return userDao.selectAllUser();
    }

}

< 十 >测试 SERVICE 配置

package test;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import model.User;
import service.inter.UserService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring-mybatis.xml", "classpath:spring-service.xml"})
public class Test02 {
    
    @Autowired
    public UserService userService;
    
    @Test
    public void test(){
        User user = new User();
        user.setUserName("张崇超");
        user.setUserSex(1);
        System.out.println(userService.selectAllUser(user)); 
    }
    
}

< 11 > 配置 SPRING MVC

<?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"
    xsi:schemaLocation="http://www.springframework.org/schema/mvc 
    http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context 
    http://www.springframework.org/schema/context/spring-context-4.1.xsd"
>
    
    <!-- 开启 SPRING 注解模式 -->
    <mvc:annotation-driven/>
    
    <!-- 加入对静态资源的处理, 将 SPRING MVC 无法处理的请求交还给 SERVLET -->
    <mvc:default-servlet-handler/>
    
    <!-- 配置视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WebPage/"/>
        <property name="suffix" value=".html"></property>
    </bean>
    
    <!-- 自动扫描 WEB 相关的包 -->
    <context:component-scan base-package="controller"/>

</beans>

< 12 > WEB-XML 的配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app 
    version="2.5" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</web-app>

< 13 > CONTROLLER 类

package controller;

import java.io.IOException;
import java.io.Writer;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import model.User;
import service.inter.UserService;

@Controller
