第四十五章 SpringBoot全局异常处理

单个controller范围的异常处理

@RestController

public class AdviceController {

@ExceptionHandler(RuntimeException.class)

public ExceptionResponse exceptionHandler() {

return new ExceptionResponse("1001", "系统繁忙")

}

}

全局异常处理

package com.container.web.handler;

import javax.servlet.http.HttpServletRequest;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.web.bind.annotation.ControllerAdvice;

import org.springframework.web.bind.annotation.ExceptionHandler;

@ControllerAdvice

public class GlobalDefaultExceptionHandler {

private static final Logger log = LoggerFactory.getLogger(GlobalDefaultExceptionHandler.class);

@ExceptionHandler(value = Exception.class)

private void defaultErrorHandler(HttpServletRequest req, Exception e) {

log.error("catch exception by global exception handler");

e.printStackTrace();

}

}
