AOP__事务配置（简单代码xml配置，注解等）

不标准的MVC：

1、XML配置的方式
DAO:

@Repository
public class UserDao {
    @Resource
    private JdbcTemplate jdbcTemple = new JdbcTemplate();
    
    public void insUser() throws SQLException {
        // TODO Auto-generated method stub
        String sql = "INSERT INTO emp(ename,job,mgr,sal,comm,deptno) VALUES(?,?,?,?,?,?);";
        int update = jdbcTemple.update(sql, "ename222","job",1000,1000,1000,20);
        System.out.println(update);
    }
    
    public void updUser() throws SQLException  {
        // TODO Auto-generated method stub
        String sql = "UPDATE emp SET ename = ?,job = ?,mgr = ?,sal = ?,comm = ?,deptno =? WHERE empno = ?;;";
        int update = jdbcTemple.update(sql, "ename111","job111",1000,1000,1000,20,7934);
        System.out.println(update);
        
    }

@Service
public class UserService {
    @Autowired
    private UserDao userDao;
    
        public int insUser() throws SQLException {
        // TODO Auto-generated method stub
        userDao.insUser();
        
        return 0;
    }
    
public int updUser() throws SQLException {
        // TODO Auto-generated method stub
        userDao.updUser();
        return 0;
    }
}

applicationContext.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:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop"

        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
    
    <!-- 开启扫描 -->
    <context:component-scan base-package="com.dao,com.pojo,com.service"></context:component-scan>
    <!-- 配置DataSource -->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <!-- 配置数据库的相关信息  -->
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/demo?characterEncoding=utf-8"/>
        <property name="username" value="xxx"/>
        <property name="password" value="xxxx"/>
    </bean>
    <!-- 配置JdbcTemplate,(可以更改这里为了简便) -->
    <bean class="org.springframework.jdbc.core.JdbcTemplate" id="jdbcTemplate">
        <!-- 构造注入的方式 设置DataSource，也可使用设值注入的方式 -->
        <constructor-arg name="dataSource" ref="dataSource"/>
    </bean>
    
    <!-- 配置Spring的事务管理 -->
    <!-- 事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    
    <!-- 设置事务的传播属性 -->
   <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
        <!-- 方法的命名以ins或者upd开头的，类似相关命名，采用通配符 -->
            <tx:method name="ins*" propagation="REQUIRED"/>
            <tx:method name="upd*" propagation="REQUIRED"/>
        </tx:attributes>
    </tx:advice>
    <!-- 配置AOP事务 -->
   <aop:config>
<!-- 切点 -->
        <aop:pointcut expression="execution(* com.service.UserService.*(..))" id="myPointcut"/>
        <aop:advisor advice-ref="txAdvice"  pointcut-ref="myPointcut"/>
    </aop:config>
</beans>

2、采用注解的方式：
DAO：

@Repository
public class UserDao {
    @Resource
    private JdbcTemplate jdbcTemple = new JdbcTemplate();
    
    /*public void selUser() {
        // TODO Auto-generated method stub
        String sql = "SELECT * FROM emp";
//      RowCallbackHandler rowMapper;BeanPropertyRowMapper
        List<User> list = jdbcTemple.query(sql, new BeanPropertyRowMapper(User.class));
        for (User user : list) {
            System.out.println(user);
        }
    }*/
    
    public void insUser() throws SQLException {
        // TODO Auto-generated method stub
        String sql = "INSERT INTO emp(ename,job,mgr,sal,comm,deptno) VALUES(?,?,?,?,?,?);";
        int update = jdbcTemple.update(sql, "ename222","job",1000,1000,1000,20);
        System.out.println(update);
    }
    
    public void updUser() throws SQLException  {
        // TODO Auto-generated method stub
        String sql = "UPDATE emp SET ename = ?,job = ?,mgr = ?,sal = ?,comm = ?,deptno =? WHERE empno = ?;;";
        int update = jdbcTemple.update(sql, "ename111","job111",1000,1000,1000,20,7934);
        System.out.println(update);
        
    }
}

Service,使用@Transactional

@Service
public class UserService {
    @Autowired
    private UserDao userDao;
    
    @Transactional( propagation = Propagation.REQUIRES_NEW)
    public int insUser() throws SQLException {
        // TODO Auto-generated method stub
        userDao.insUser();
        
        return 0;
    }
    
    @Transactional( propagation = Propagation.REQUIRES_NEW)
    public int updUser() throws SQLException {
        // TODO Auto-generated method stub
        userDao.updUser();
        return 0;
    }
}

Application.xml配置：

<?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: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/beans/spring-beans-4.3.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">
    
    <!-- 开启扫描 -->
    <context:component-scan base-package="com.dao,com.pojo,com.service"></context:component-scan>
    <!-- 配置DataSource -->
    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <!-- 配置数据库的相关信息  -->
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/demo?characterEncoding=utf-8"/>
        <property name="username" value="root"/>
        <property name="password" value="rootzsl"/>
    </bean>
    <!-- 配置JdbcTemplate,(可以更改这里为了简便) -->
    <bean class="org.springframework.jdbc.core.JdbcTemplate" id="jdbcTemplate">
        <!-- 构造注入的方式 设置DataSource，也可使用设值注入的方式 -->
        <constructor-arg name="dataSource" ref="dataSource"/>
    </bean>
    
    <!-- 配置Spring的事务管理 -->
    <!-- 事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    
    <!-- 开启事务注解 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>
</beans>
