源码下载

    MyBatis与spring的整合-添加事务-src.zip

在上篇的基础上做如下修改(添加)

1. 添加jar

    com.springsource.org.aspectj.tools-1.6.6.RELEASE.jar

2. ApplicationContext.xml 事务配置

	<tx:advice id="userTxAdvice" transaction-manager="transactionManager">
		<tx:attributes>
			<tx:method name="delete*" propagation="REQUIRED" />
			<tx:method name="save*" propagation="REQUIRED" />
			<tx:method name="update*" propagation="REQUIRED" />
			<tx:method name="find*" read-only="true" />
			<tx:method name="get*" read-only="true" />
			<tx:method name="select*" read-only="true" />
		</tx:attributes>
	</tx:advice>

	<aop:config>
		<!-- 第一个"*"代表所有类,第二个"*"代表所有方法 ".."代表任意参数 -->
		<aop:pointcut id="pc" expression="execution(* com.hehe.mybatis.service.*.*(..))" />
		<!--把事务控制在Service层-->
		<aop:advisor pointcut-ref="pc" advice-ref="userTxAdvice" />
	</aop:config>
	<!-- =================================================================================    -->	

3. 添加 service 层

public interface UserService {
    
    public void updateUser(User user);
}
public class UserServiceImpl implements UserService {

    private UserDao userDao;
    
    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }
    
    @Override
    public void updateUser(User user) {
        userDao.updateUser(user);
        System.out.println( 1/0 );
    }
}

4. junit test

 4.1 TestUserDao

/*
	<update id="updateUserByCondition" parameterType="User">
		update user
		<set>
			<if test="name != null">
				name = #{name} ,
			</if>
			<if test="address != null">
				address = #{address}
			</if>
		</set>
		where id = #{id}
	</update>
 */
	@Test
	public void testUpdateUserByCondition() {
		UserDao userDao = (UserDao) context.getBean("userDao");
		User user = new User();
		user.setId("0001");
		user.setName("zhangsan44");
		userDao.updateUser(user);
	}	
		

 4.2 TestUserService

	@Test
	public void testUpdateUser() {
		ApplicationContext context = new ClassPathXmlApplicationContext("ApplicationContext.xml");
		UserService userService = (UserService) context.getBean("userService");
		
		User user = new User();
		user.setId("0001");
		user.setName("zhangsan77");
		userService.updateUser(user);
	}

5. 完整的 ApplicationContext.xml
