Spring+Mybatis+mysql配置

1. mybatis的映射文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper SYSTEM "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.lky.dao.UserMapper">
    <insert id="add" parameterType="com.lky.model.User">
        insert into s_user(user_name,user_birthday,user_salary) values(#{name},#{birthday},#{salary})
    </insert>

    <update id="update" parameterType="com.lky.model.User">
        update s_user set user_name=#{name},user_birthday=#{birthday},user_salary=#{salary} where user_id=#{id}
    </update>

    <delete id="delete" parameterType="int">
        delete from s_user where user_id=#{id}
    </delete>

    <select id="findById" parameterType="int" resultType="com.lky.model.User">
        select user_id id,user_name name,user_birthday birthday,user_salary salary from s_user where user_id=#{id}
    </select>

    <select id="findAll" resultType="com.lky.model.User">
        select user_id id,user_name name,user_birthday birthday,user_salary salary from s_user
    </select>

</mapper>

2.mybatis的配置文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration SYSTEM "http://mybatis.org/dtd/mybatis-3-config.dtd" >
<configuration>
    <mappers>
        <mapper resource="com/lky/dao/UserMapper.xml"/>
    </mappers>
</configuration>

3.Spring的配置文件

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

    http://www.springframework.org/schema/aop
    http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
    <!-- 配置数据源   DriverManagerDataSource-->
    <bean id="jdbcDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName">
            <value>com.mysql.jdbc.Driver</value>
        </property>
        <property name="url">
            <value>jdbc:mysql://10.21.25.228:3306/mybatis</value>
        </property>
        <property name="username">
            <value>root</value>
        </property>
        <property name="password">
            <value>root</value>
        </property>
    </bean>

       <!-- mybatis的sqlSession的工厂 sqlSessionFactoryBean -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="jdbcDataSource" />
        <property name="typeAliasesPackage" value="com.lky.model"/>
    </bean>

       <!-- mybatis自动扫描加载sql映射文件、接口：MapperScannerConfigurer
         basePackage:指定sql映射文件，接口所在的包（自动扫描）
         sqlSessionFactory: 引用上面定义的sqlSessionFactory
       -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.lky.dao"/>
        <property name="sqlSessionFactory"  ref="sqlSessionFactory"/>
    </bean>

        <!-- 事务管理  DataSourceTransactionManager
            dataSource:引用上面定义的数据源
         -->
    <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource"  ref="jdbcDataSource"/>
    </bean>

       <!-- 使用声明的事务
               使用上面定义的事务
        -->
    <tx:annotation-driven transaction-manager="txManager"/>
</beans>

4.实体类

package com.lky.model;

import java.util.Date;

public class User {
    private int id;
    private String name;
    private Date birthday;
    private double salary;
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Date getBirthday() {
        return birthday;
    }
    public void setBirthday(Date birthday) {
        this.birthday = birthday;
    }
    public double getSalary() {
        return salary;
    }
    public void setSalary(double salary) {
        this.salary = salary;
    }
    public User(int id, String name, Date birthday, double salary) {
        super();
        this.id = id;
        this.name = name;
        this.birthday = birthday;
        this.salary = salary;
    }
    public User() {
        super();
    }

    @Override
    public String toString() {
        return "User [id=" + id + ", name=" + name + ", birthday=" + birthday
                + ", salary=" + salary + "]";
    }

}

5.接口类

package com.lky.dao;

import java.util.List;
import com.lky.model.User;

public interface UserMapper {
    public void add(User user);
    public void update(User user);
    public void delete(User user);
    public void findById(int id);
    public  List<User> findAll();

}

6.测试文件

package com.lky.test;

import java.util.Date;
import java.util.List;

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 com.lky.dao.UserMapper;
import com.lky.model.User;

@RunWith(SpringJUnit4ClassRunner.class)//使用Spring的测试框架
@ContextConfiguration("/beans.xml")//加载spring的配置文件bean
public class smTest {

    @Autowired //自动注入该对象
    private UserMapper userMapper;

    @Test
    public void testAdd(){
        User user=new User(-1,"tom",new Date(),12345);
        userMapper.add(user);

    }

    @Test
    public void testfindByName(){
        System.out.println(userMapper.findByName("tom"));

    }

    @Test
    public void testfingAll(){
        List<User> ss=userMapper.findAll();
        System.out.println(ss);
    }
}
