Question

大家好我在桌面Spring应用程序上使用log4j。每当我故意使用无效的用户名/密码进行数据库连接时，我就无法在我的日志文件上记录异常。我无法记录异常： java.sql.SQLException：ORA-01017：用户名/密码无效;登录被拒绝

下面是Stacktrace和我的log4j.properties

LOG4J属性

Answer 1

问题似乎在于AOP事务对象中发生异常。由于AOP通过创建代理对象来工作，因此抛出异常而不是在您尝试捕获异常的位置。我相信有一个AOP注释用于捕获异常，但我现在只能想到@Around注释。

我自己刚刚学会了基本的AOP，但这里有一个很好的可用注释摘要，包括陷阱抛出异常的注释：

@Aspect
public class AfterThrowingExample {

  @AfterThrowing("com.xyz.myapp.SystemArchitecture.dataAccessOperation()")
  public void doRecoveryActions() {
    // ...
  }

}

Answer 2

Spring不记录SQL异常。相反，它只是将它们包装在相应的DataAccessException中并进一步抛出。应用程序负责捕获和处理（例如，记录）运行时异常。为了避免捕获整个代码，你应该尽可能在调用堆栈中执行它。

无法在Log4j Spring桌面应用程序中记录java.sql.SQLException
