@Tansactional 和@Aspect 排序

Question

我想在 @Transactional 事务开始之前执行我的代码。

@Aspect
@Order(Ordered.HIGHEST_PRECEDENCE)
//@Order(Ordered.LOWEST_PRECEDENCE)
public class SynchronizerAspect {

  @Pointcut("execution(public * xxx.xxx.services.*.*(..))")
  private void anyServiceOperation() {
  }

  @Around("anyServiceOperation()")
public Object synchronizerAdvice(ProceedingJoinPoint joinPoint) throws Throwable {
    System.out.println("Synchronizing : " + joinPoint.getSignature().getName());
return joinPoint.proceed();
  }

当我调用一个标记为@Transactional 的服务方法时，我总是在事务中执行方面代码：

[INFO] INFO: FETCH created: Fri Oct 30 15:43:11 UTC 2015 duration: 0 connection: 40 statement: 999 resultset: 0
[INFO] paĹş 30, 2015 3:43:11 PM com.mysql.jdbc.log.Slf4JLogger logInfo

[INFO] Synchronizing : getCompany

我也设置了@EnableTransactionManagement(order = 500)

我应该做些什么才能使其正常工作？

此外，我使用aspectj-maven-plugin:1.7 在编译时编织切面。

这么聪明还用@Ordering吗？

不管我如何设置@Order aspectj-maven-plugin 日志显示我的@Aspect 是在@Transactional 之前添加的

[INFO] Join point 'method-execution(boolean xxx.xxx.services.LicenseServiceImpl.checkLicenseFile(int, int))' in Type 'xxx.xxx.services.LicenseServiceImpl' (LicenseServiceImpl.java:261) advised by around advice from 'xxx.xxx.aop.SynchronizerAspect' (SynchronizerAspect.java:29)
[INFO] Join point 'method-execution(boolean xxx.xxx.services.LicenseServiceImpl.checkLicenseFile(int, int))' in Type 'xxx.xxx.services.LicenseServiceImpl' (LicenseServiceImpl.java:261) advised by around advice from 'org.springframework.transaction.aspectj.AnnotationTransactionAspect' (spring-aspects-4.2.2.RELEASE.jar!AbstractTransactionAspect.class:66(from AbstractTransactionAspect.aj))

Answer 1

好的。我知道答案：

如果使用Spring的基于代理的AOP，@Order注解可以正常工作。对于加载时编织，需要声明方面优先级：

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.DeclarePrecedence;

@Aspect
@DeclarePrecedence("xxx.xxx.aop.SynchronizerAspect, org.springframework.transaction.aspectj.AnnotationTransactionAspect, *")
public class AspectPrecedence {
  // empty
}

要从 AutoProxy（默认）切换到 AspectJ：

@EnableAspectJAutoProxy
@EnableTransactionManagement(mode = AdviceMode.ASPECTJ)
