Springboot 异常处理

@RestControllerAdvice
public class ExceptionHandlerController {

    @ExceptionHandler(value = {ArithmeticException.class})
    public String ArithmeticExceptionHandler(ArithmeticException e){
        return "算数异常"+e.toString();
    }
}

这样就可以了 让我们来测试一下

@GetMapping("/testServletApi")
public String testServletApi(HttpServletRequest request) {
    int a =10/0;
    return "testServletApi";
}
