spring aop 异常拦截

统一拦截controller异常

//@RestControllerAdvice
@ControllerAdvice({"com.my.learn.controller"})
public class ExceptionControllerAdvice {
    @ResponseBody
    @ExceptionHandler(MyRuntimeException.class)
    public ReturnEntity handleException(MyRuntimeException e) {
        System.out.println(" MyRuntimeException");
        return new ReturnEntity(400, e.getMessage(), null);
    }
    @ResponseBody
    @ExceptionHandler(RuntimeException.class)
    public ReturnEntity handleException(RuntimeException e) {
        System.out.println(" RuntimeException");
        return new ReturnEntity(400, e.getMessage(), null);
    }
    @ResponseBody
    @ExceptionHandler(Exception.class)
    public ReturnEntity handleException(Exception e) {
        System.out.println(" Exception");
        return new ReturnEntity(400, e.getMessage(), null);
    }
}

具体的异常拦截顺序，由spring自行处理，与方法顺序无关。
