一.错误的处理
方法一:Spring Boot 将所有的错误默认映射到/error, 实现ErrorController
@Controller @RequestMapping(value = "error") public class BaseErrorController implements ErrorController { private static final Logger logger = LoggerFactory.getLogger(BaseErrorController.class); @Override public String getErrorPath() { logger.info("出错啦!进入自定义错误控制器"); return "error/error"; } @RequestMapping public String error() { return getErrorPath(); } }
方法二:添加自定义的错误页面
2.1 html静态页面:在resources/public/error/ 下定义
如添加404页面: resources/public/error/404.html页面,中文注意页面编码
2.2 模板引擎页面:在templates/error/下定义
如添加5xx页面: templates/error/5xx.ftl
注:templates/error/ 这个的优先级比较高 resources/public/error/
package com.demo.example.handler; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.http.HttpStatus; import org.springframework.web.bind.annotation.ControllerAdvice; import org.springframework.web.bind.annotation.ExceptionHandler; import org.springframework.web.bind.annotation.ResponseStatus; import org.springframework.web.servlet.ModelAndView; @ControllerAdvice public class ErrorExceptionHandler{ private static final Logger logger = LoggerFactory.getLogger(ErrorExceptionHandler.class); @ExceptionHandler({RuntimeException.class}) @ResponseStatus(HttpStatus.OK) public ModelAndView processException(RuntimeException exception) { logger.info("自定义异常-RuntimeException"); ModelAndView modelAndView = new ModelAndView(); modelAndView.addObject("roncooException", exception.getMessage()); modelAndView.setViewName("error/500"); return modelAndView; } @ExceptionHandler({Exception.class}) @ResponseStatus(HttpStatus.OK) public ModelAndView processException(Exception exception) { ModelAndView modelAndView = new ModelAndView(); logger.info("自定义异常-Exception"); modelAndView.addObject("roncooException", exception.getMessage()); modelAndView.setViewName("error/500"); return modelAndView; } }
