@Async 和 @Transactional：不工作

Posted 2023-02-26

【中文标题】@Async 和 @Transactional：不工作

【英文标题】：@Async and @Transactional: not working

【发布时间】：2013-11-24 23:50:34

【问题描述】：

请查看代码。

当我调用 @Async loadMarkUpPCT() 方法时，数据不会提交到表中。它表现得好像没有牵引力。

当我从 loadMarkUpPCT（1 类）中删除 @Async（即非异步）时，数据已按预期提交并正常：事务性）

我期望@Async 和@Transactional 会得到相同的结果，但事实并非如此。请解释或我做错了什么？

已编辑：我刚刚编辑发布代码+日志

流动方式： AppDataLoaderController 调用 AppDataLoaderService 调用 DataMigrationService 调用 JpaDataMigrationDao

package concepts.web.rest.resource.spring.impl;

@Controller
@RequestMapping("/appdataloader")
public class AppDataLoaderController 

    @RequestMapping("/loadMarkupPct")
    @ResponseStatus(HttpStatus.ACCEPTED)    
    public void loadMarkUpPCT() 
        try 
            this.appDataLoaderService.loadMarkUpPCT();
         catch (ServiceException e) 
            e.printStackTrace();
        
    



package concepts.service.impl;  

@Service("appDataLoaderService")
public class AppDataLoaderServiceImpl implements AppDataLoaderService 

    @Async
    @Override       
    public void loadMarkUpPCT() throws ServiceException 
        logger.debug("@Async loadMarkUpPCT");       
        dataMigrationService.loadMarkUpPCT();
       


package concepts.service.impl;

@Service
@Scope("prototype")
public class DataMigrationServiceImpl implements DataMigrationService 

    @Override
    public void loadMarkUpPCT() throws ServiceException 
        // TODO Auto-generated method stub
        Assert.notNull(markUpPCTDataLoader);
        List<MarkUpPCT> markUpPCTs=markUpPCTDataLoader.getMarkupCoef();
        for (MarkUpPCT markUpPCT: markUpPCTs)
            dataMigrationDao.storeMarkUpPCT(markUpPCT);
    


package concepts.persistence.impl.jpa;

@Repository
public class JpaDataMigrationDao extends DataMigrationDaoAdapter
    @PersistenceContext
    private EntityManager entityManager;

    @Transactional
    @Override
    public void storeMarkUpPCT(MarkUpPCT markUpPCT) 
        entityManager.persist(markUpPCT);

【问题讨论】：

请发布@Async 和@Transactinal 的配置。

我用的是Spring 3.2 applicationContext-service.xml applicationContext-jpa.xml

请同时发布这些文件和您的课程所在的包。

流程：AppDataLoaderController 调用 AppDataLoaderService 调用 DataMigrationService 调用 JpaDataMigrationDao

Sotirios，我刚刚发布了代码+日志。

【参考方案1】：

尝试同时使用 @Transactional 注释 loadMarkUpPCT() 方法并告诉我们这是否有效。

【参考方案2】：

我刚刚遇到了同样的问题。原来我忘了添加@EnableAsync 注释。
