spring + mybatis 創建項目

創建用戶類

package com.cl.vo.spring;

import java.util.Date;

public class SUser {

       private int id ;

       private String name ;

       private Date birthday ;

       private double salary ;

}

配置beans.xml

<?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:tx="http://www.springframework.org/schema/tx"

       xsi:schemaLocation="http://www.springframework.org/schema/beans

           http://www.springframework.org/schema/beans/spring-beans-2.5.xsd

           http://www.springframework.org/schema/tx

           http://www.springframework.org/schema/tx/spring-tx-3.0.xsd

           " >

         <!-- 數據源 DriverManagerDataSource-->

         <bean id= "ds" class="org.springframework.jdbc.datasource.DriverManagerDataSource" >

             <property name="driverClassName" value="com.mysql.jdbc.Driver" />

             <property name="url" value="jdbc:mysql://localhost:3306/mybatis" />

             <property name="username" value="root"/>

             <property name="password" value="admin"/>

         </bean>

        

        

         <!-- mybatis 的sqlsessionFactory

                  dataSource  引用數據源

                  typeAliasesPackage    指定實體類的包名

           -->

         <bean id= "clSqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" >

                   <property name="dataSource" ref="ds"></ property>

                   <property name="typeAliasesPackage" value="com.cl.vo.spring" ></property>

          </bean>

         

          <!--mybatis 自動掃描sql映射文件 MapperScannerConfigurer

                  basePackege   指定 sql映射文件/接口所在的包（自動掃描）

                  sqlSessionFactory   引用上面定義的sqlSessionFactory

          -->

         <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" >

                   <property name="basePackage" value="com.cl.mapper.spring" />

                   <property name="sqlSessionFactoryBeanName" value="clSqlSessionFactory" ></property>

         </bean>

         <!--事務管理    DataSourceTransactionManager

         dataSource:引用上面定義的數據源

             -->

         <bean id= "txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager" >

             <property name="dataSource" ref="ds"></ property>

          </bean>

         

          <!--使用聲明式事務 

          transaction-manager  引用上面定義的事務管理

          -->

          <tx:annotation-driven transaction-manager="txManager" />

           </beans>

寫用戶接口

public interface SUserMapper {

       @Select("insert into s_user (user_name,user_birthday,user_salary      )values(#{name},#{birthday},#{salary})" )

       public void save(SUser su);

      

       public void update(SUser su);

      

       public void delete(int id);

      

       public SUser findById(int id);

      

       public List<SUser> findAll();

}

配置mybatis的conf.xml和配SUserMapper.xml

conf.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>

    <mappers >

        <mapper class="com.cl.mapper.spring.SUserMapper" />

    </mappers >

   

</configuration>

SUserMapper.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="com.cl.mapper.spring.SUserMapper" >

   <update id="update" parameterType="SUser" >

      update s_user set user_name = #{name} ,user_birthay =#{birthday},user_salary=#{salary}

    </update >

   

    <select id="findById" parameterType="int" resultType= "SUser">

      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="SUser" >

      select user_id id,user_name name,user_birthday birthday,user_salary salary from s_user

    </select >

   

    <delete id="delete"  parameterType="int" >

      delete from s_user where user_id = #{id}

    </delete >

   

</mapper>

寫Client 文件

@RunWith(SpringJUnit4ClassRunner.class)//用spring的測試包

@ContextConfiguration ("/beans.xml" )//加載spring 的配置文件

public class MSTest {

       @Autowired

       private SUserMapper SUserMapper ;

      

       @Test

       public void testAdd() {

            SUser su = new SUser(-1, "Tom", new Date(), 12345);

            SUserMapper.save( su);

             SUserMapper.findById(1);

      }

}
