Java编程Throwable与Exception
Throwable
其实是Exception的父类。关系瞬间明确。
哪里可以见到神龙见首不见尾的Throwable呢?
一般来说切面编程的环绕通知会有的,例如:
import org.springframework.stereotype.Component;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Around;
@Component
@Aspect
public class TestAspect{
@Around(value = "execution(* com.test.controller.*Controller.*(..))")
public Object aroundMethod(ProceedingJoinPoint joinpoint)throws Throwable{
Object result=null;
try{
result = joinpoint.proceed();
}catch(Throwable e){
throw e;
}
}
}
