Spring基于注解的事务控制

 

准备jar包
<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-context</artifactId>
  <version>5.0.2.RELEASE</version>
</dependency>
<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-jdbc</artifactId>
  <version>5.0.2.RELEASE</version>
</dependency>
<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-tx</artifactId>
  <version>5.0.2.RELEASE</version>
</dependency>

<dependency>
  <groupId>mysql</groupId>
  <artifactId>mysql-connector-java</artifactId>
  <version>5.1.6</version>
</dependency>

开始配置
<?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:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
      https://www.springframework.org/schema/beans/spring-beans.xsd
      http://www.springframework.org/schema/context
      https://www.springframework.org/schema/context/spring-context.xsd
      http://www.springframework.org/schema/tx
      https://www.springframework.org/schema/tx/spring-tx.xsd">
<!--配置扫描路径-->
<context:component-scan base-package="com.aiitec"></context:component-scan>

<!--事务控制begin-->
  <!--配置事务管理器-->
  <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"></property>
  </bean>
  <!--开启Spring对注解事务的支持-->
  <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>
<!--事务控制end-->

<!--配置spring-jdbc-template数据源 begin-->
  <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
    <property name="url" value="jdbc:mysql://localhost:3306/eesy"></property>
    <property name="username" value="root"></property>
    <property name="password" value="root"></property>
  </bean>

  <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
    <property name="dataSource" ref="dataSource"></property>
  </bean>
<!--配置spring-jdbc-template数据源 end-->
</beans>

在Service的实现类中使用@Transactional注解
事务的属性都改为在@Transactional(这里)配置,
用在类上,该类的所有public方法都将支持事务
方法上的@Transactional优先级较
