错误页面处理

错误页面

resources/templates/error/4xx.ftl

　　错误页面路径配置：server.error.path

异常处理器来进行日志输出

　　如抛出异常

if(one!=null){
            throw new IllegalArgumentException();
        }

　　捕获异常

package com.xiaoping.houseweb.controller;

import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;

import javax.servlet.http.HttpServletRequest;

@ControllerAdvice
@Slf4j
public class ErrorHandler {
    @ExceptionHandler(value = {Exception.class,RuntimeException.class})
    public String error500(HttpServletRequest request,Exception e){
        log.error(e.getMessage(),e);
        log.error(request.getRequestURL()+" encounter 500");
        return "error/500";
    }
}

　　结果打印日志
