java Spring AOP切入点表达式，不包括特定的返回类型或参数

Question

@AfterReturning(value = "execution(* org.springframework.data.repository.CrudRepository.save(..)) ", returning = "result")
public void repo(JoinPoint joinPoint, Object result) {
    // ... 
}

此切入点涵盖所有保存或更新操作，而不考虑传递的参数或返回类型，但我只想排除xyz。在参数或返回类型中初始化。这怎么可能？ 我不能提及所有保存操作，因为总共有50多个型号，但我只希望涵盖其中48个

Answer 1

@Pointcut("execution(* com.yash.arci.repository.*.save(*))")
public void allrepository() {
}

@Pointcut("execution(* com.yash.arci.repository.AuditRepository.save(*))")
public void auditrepository() {
}

@Before(value = "allrepository() && !auditrepository()")
public void repo(JoinPoint joinPoint) {
}

这是另一种解决方案

Answer 2

您可以声明包含和排除的方法签名，并像这样组合它们

@Pointcut("execution(* org.springframework.data.repository.CrudRepository.save(..))")
public void any() {
}

@Pointcut("execution(* org.springframework.data.repository.CrudRepository.save(MyClass1))" +
        " || execution(* org.springframework.data.repository.CrudRepository.save(MyClass2))")
public void excluded() {
}

@AfterReturning(value = "any() && !excluded()", returning = "result")
public void repo(JoinPoint joinPoint, Object result) {
    // ...
}

Answer 3

记住erasure of a type可以做的最简单的事情是，如果arg类型是XYZ，则从方法返回而不做任何事情

@Pointcut("execution(* org.springframework.data.repository.CrudRepository+.save(..))")
  public void savePointCut() {
    // savePointCut
  }

  @AfterReturning(value = "savePointCut()", returning = "result")
  public void afterReturning(JoinPoint joinPoint, Object result) {
    if (joinPoint.getArgs()[0] instanceof XYZ) return;
    logger.info("AfterReturning :[{}]", joinPoint.getArgs());
  }
