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

Question

大家好，我在桌面 Spring 应用程序上使用 log4j。每当我故意为数据库连接使用无效的用户名/密码时，我都很难在日志文件中记录异常。我无法记录异常:java.sql.SQLException: ORA-01017: invalid username/password;登录被拒绝

下面是 Stacktrace 和我的 log4j.properties

LOG4J 属性

log4j.rootLogger=INFO, file, stdout, ERROR

# Application logging options

log4j.logger.jdbc.resultset=ERROR

log4j.logger.jdbc.resultsettable=OFF

log4j.logger.org.springframework.jdbc.datasource.DataSourceTransactionManager=ERROR
log4j.logger.org.springframework.transaction=ERROR
log4j.logger.java.sql.SQLException=ALL

由以下原因引起:java.sql.SQLException:ORA-01017:无效的用户名/密码；登录被拒绝

Answer 1

问题似乎出在 AOP 事务对象中发生异常。由于 AOP 通过创建代理对象来工作，因此异常将在那里抛出，而不是您 try catch 异常的地方。我相信虽然有一个 AOP 注解可以捕获异常，但目前我只能想到 @Around 注解。

我自己刚刚学习了基本的 AOP，但这里是可用注释的一个很好的总结，包括捕获抛出异常的注释:

@Aspect
public class AfterThrowingExample {

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

}
