SpringBoot2.0 拦截404，500页面方法

 

1.创建 HttpErrorController类，实现ErrorPageRegistrar

package team.haierbrother.lzcourt.erro;

import org.springframework.boot.web.server.ErrorPage;
import org.springframework.boot.web.server.ErrorPageRegistrar;
import org.springframework.boot.web.server.ErrorPageRegistry;
import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Component;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
 * HttpErrorController 页面拦截跳转
 * 基于SpringBoot2.0的ErrorPageConfig页面拦截跳转
 * @author 周子敖
 * @version 1.0, 2018-12-24
 * @since CommonLog1.0
 */
@Component
public class implements ErrorPageRegistrar {
    

    @Override
    public void registerErrorPages(ErrorPageRegistry errorPageRegistry) {
            /*1、按错误的类型显示错误的网页*/
            /*错误类型为404，找不到网页的，默认显示404.html网页*/
            ErrorPage e404 = new ErrorPage(HttpStatus.NOT_FOUND, "/error/404");
            //错误类型为500，表示服务器响应错误，默认显示500.html网页
            ErrorPage e500 = new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/error/500");
            errorPageRegistry.addErrorPages(e404, e500);
        
    }
 
}

2.创建ErrorController控制器实现页面跳转

package team.haierbrother.lzcourt.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
/**
 * ErrorController 页面拦截跳转
 * 基于SpringBoot2.0的ErrorPageConfig页面拦截跳转
 * @author 周子敖
 * @version 1.0, 2018-12-24
 * @since CommonLog1.0
 */
@Controller
@RequestMapping("/error")
public class ErrorController {
    /**
     * 404页面
     */
    @GetMapping(value = "/404")
    public String error_404() {
        return "errorpages/404";  
    }

    /**
     * 500页面
     */
    @GetMapping(value = "/500")
    public String error_500() {
        return "errorpages/500";  
    }

}
