SpringMVC配置 事务管理

1、确保持久层配置完毕

2、pom.xml里追加spring-tx

3、application-context.xml追加

    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>
    <tx:annotation-driven transaction-manager="transactionManager" />

    <context:component-scan base-package="io.deolin.service" />

注意业务层的包名

4、在具体的业务方法上追加@Transactional注解

配置完成，通过两个insert方法之间追加一个异常来测试能否成功回滚

@Service
public class MineServiceTxImpl implements MineService {

    private static final Logger log = LogManager.getLogger(MineServiceTxImpl.class);

    @Autowired
    private UserMapper userMapper;

    @Override
    @Transactional
    public void addUser() throws Exception {
        log.info("开始");
        UserPo po = new UserPo();
        po.setUsername("sss");
        po.setPassword("aaa");

        userMapper.add(po);
        Integer.valueOf("a");
        userMapper.add(po);
        log.info("结束");
    }

}
