需要Spring Transaction传播,REQUIRES_NEW

Question

在下面的代码方法doService1()更新正确的SQL但doService2()sql有一些问题,但是当我调用doService()它必须提交doService1()更新到DB,即使doService2()有一个sql exception因为doService2() 有一个REQUIRES_NEW Propagation类型,但当我doService1()没有这个更新不提交数据库..

@Service public class DbClass {

      static Logger log = Logger.getLogger(
              DbClass.class.getName());

@Autowired
private DataSource dataSource;

@Transactional(propagation=Propagation.REQUIRED)
public void doService(){
    doService1();
    doService2();
}

@Transactional(propagation=Propagation.REQUIRED)
public void doService1(){
    JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
    String sql = "  update BATCHJOBSTATUS set PROCESSINGDATE = '20130322'  " ;
    int rowCount1 =  jdbcTemplate.update(sql);
    System.out.println(" rowCount1 >" + rowCount1);
}

@Transactional(propagation=Propagation.REQUIRES_NEW)
public void doService2(){
    JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
    String sql = "  update aa set a_name = 'hhh' where a_id = 4 and " ;
    int rowCount1 =  jdbcTemplate.update(sql);
    System.out.println(" rowCount2 >" + rowCount1);
}   
}

正如你们的建议以下列方式进行测试,但仍面临同样的问题.在这里,我doService2()在一个单独的类,但即使仍然有上述相同的问题

@Service
public class DbClass {

  static Logger log = Logger.getLogger(
          DbClass.class.getName());

@Autowired
private DataSource dataSource;

@Autowired
private DbClass2 dbClass2;

@Transactional
public void doService(){
    doService1();
    dbClass2.doService2();
}

@Transactional(propagation=Propagation.REQUIRED )
public void doService1(){
    JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);
    String sql = "  update BATCHJOBSTATUS set PROCESSINGDATE = '20130322'  " ;
    int rowCount1 =  jdbcTemplate.update(sql);
    System.out.println(" rowCount1 >" + rowCount1);

    }


}


@Service
public class DbClass2 {


@Autowired
private DataSource dataSource;

@Transactional(propagation=Propagation.REQUIRES_NEW)
public void doService2() {
    System.out.println("*******doService2*********`");

    JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);

    String sql = "  update aa set a_name = 'hhh' where a_id_ = 4  " ;

    int rowCount2 =  jdbcTemplate.update(sql);

    System.out.println(" rowCount2 >" + rowCount2);

}

}

Answer 1

我之前遇到了同样的问题并且在这里解决了:@Transactional的奇怪行为(propagation = Propagation.REQUIRES_NEW)

使用默认设置时,doService2()从同一个类调用时不会创建任何新的事务代理,因此您的注释不是用户.

要避免此问题,您可以doService2()通过声明它来放入另一个类或使用aspectJ进行事务:<tx:annotation-driven transaction-manager="transactionManager" mode="aspectj"/>

最佳解决方案取决于您的应用.(这里的第二个似乎更合适)
