1.事務(wù)問題

spring項目中掏湾，如果配置了通用事務(wù)攒发，則在方法上單獨(dú)加上@Transational注解有滑，可能會造
成回滾失效等一些問題贷岸；比如：通用配置事務(wù)的代碼如下：

@Configuration
public class TxConfigBeanName {
  @Autowired
  private DataSourceTransactionManager transactionManager;
  // 創(chuàng)建事務(wù)通知
  @Bean(name = "txAdvice")
  public TransactionInterceptor getAdvisor() throws Exception {
    Properties properties = new Properties();
    properties.setProperty("get*", "PROPAGATION_REQUIRED,-Exception");
    properties.setProperty("query*", "PROPAGATION_REQUIRED,-Exception");
    properties.setProperty("add*", "PROPAGATION_REQUIRED,-Exception");
    properties.setProperty("save*", "PROPAGATION_REQUIRED,-Exception");
    properties.setProperty("update*", "PROPAGATION_REQUIRED,-Exception");
    properties.setProperty("remove*", "PROPAGATION_REQUIRED,-Exception");
    properties.setProperty("delete*", "PROPAGATION_REQUIRED,-Exception");
    properties.setProperty("logicDelete*", "PROPAGATION_REQUIRED,-Exception");
    TransactionInterceptor tsi = new TransactionInterceptor(transactionManager,properties);
    return tsi;
  }
  @Bean
  public BeanNameAutoProxyCreator txProxy() {
    BeanNameAutoProxyCreator creator = new BeanNameAutoProxyCreator();
    creator.setInterceptorNames("txAdvice");
    creator.setBeanNames("*Service", "*ServiceImpl");
    creator.setProxyTargetClass(true);
    return creator;
  }
}

由上述看出 save開頭的方法都有Required級別的事務(wù)壹士，給下面的方法添加自己的事務(wù)：

@Override
    @Transactional(propagation = Propagation.NESTED)
    public void saveDoSomeOperate(Map<String, Object> params) throws BusinessException {
        //do something
    }

調(diào)用saveDoSomeOperate代碼

try{
  xxxService.saveDoSomeOperate(map);
}catch(Exception e){
  log.error("系統(tǒng)錯誤", e);
}

如果saveDoSomeOperate方法報錯，按照NESTED事務(wù)傳播特性偿警，外層事務(wù)應(yīng)該不會回
滾躏救，但是這里實際情況外層事務(wù)會回滾。

如果將NESTED注解的方法名改成 doSomeOperate户敬，內(nèi)層方法出現(xiàn)異常落剪，只會自己回
滾睁本，外層調(diào)用方數(shù)據(jù)不會回滾尿庐，改造如下：

@Override
    @Transactional(propagation = Propagation.NESTED)
    public void doSomeOperate(Map<String, Object> params) throws BusinessException {
        //do something
    }
