此方法适用于项目打jar包的方式！！！
1、在config包下创建ErrorConfiguration类：
import org.springframework.boot.web.server.ErrorPage;
import org.springframework.boot.web.server.ErrorPageRegistrar;
import org.springframework.boot.web.server.ErrorPageRegistry;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Component;
/**
* <p><b>自定义错误页面(4xx/5xx)处理类</b></p>
* @Description 自定义错误页面(4xx/5xx)处理类</ p>
* @author MengMeng
* Created date: 2018/10/11
* @Since JDK 1.80_171
*/
@Component
public class ErrorConfiguration implements ErrorPageRegistrar {
@Override
public void registerErrorPages(ErrorPageRegistry registry) {
ErrorPage[] errorPages = new ErrorPage[]{
new ErrorPage(HttpStatus.FORBIDDEN, "/error/403"),
new ErrorPage(HttpStatus.NOT_FOUND, "/error/404"),
new ErrorPage(HttpStatus.INTERNAL_SERVER_ERROR, "/error/500"),
new ErrorPage(Throwable.class, "/error/500")
};
registry.addErrorPages(errorPages);
}
}
2、在controller包下创建ErrorController：
import org.apache.catalina.servlet4preview.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.security.core.context.SecurityContextHolder;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import java.util.List;
@Controller
public class ErrorController {
/**
*<p><b>自定义错误处理的Controller类</b></p>
* @Description 自定义错误处理的Controller类</ p>
* @author MengMeng
*<p>Created date: 2018/10/11</p>
* @version: 0.1
* @since JDK 1.80_144
*/
@RequestMapping(value = "/error/{code}")
public String error(@PathVariable int code, Model model) {
String pager = "";
switch (code) {
case 403:
model.addAttribute("code", 403);
pager = "error/page";
break;
case 404:
model.addAttribute("code", 404);
pager = "error/page";
break;
case 500:
model.addAttribute("code", 500);
pager = "error/page";
break;
}
return pager;
}
}
3、创建错误页面，HTML代码：
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org">
<!--
Title:错误处理页
Description：错误处理页
Author：MengMeng
Created date: 2018/10/11
Version: Html5
-->
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport"
content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" />
<title>网站访问失败</title>
<link rel="shortcut icon" th:href="@{/images/logo-black.png}"
href="/images/logo.png" type="images/x-icon" />
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta name="description" content="" />
<!-- 引入css -->
<th:block th:replace="pageFrame/basicsCss :: copy" />
</head>
<body class="hold-transition login-page">
<div class="login-box">
<!-- login-box-body -->
<div id="doc_main">
<section class="bd clearfix">
<div class="module-error">
<div class="error-main clearfix">
<div class="info">
<h2 class="title">你所访问的页面不存在！</h2>
<div class="reason">
<h3>可能的原因：</h3>
<h3>1.内容填写有错误。</h3>
<h3>2.链接过了保质期。</h3>
<h3>3.所在页面时间过长。</h3>
<h3>4.如果还未解决，请向管理员反馈！</h3>
</div>
<div class="oper">
<h3>
<a href="/login">回到网站首页></a>
</h3>
</div>
</div>
</div>
</div>
</section>
</div>
<!-- 引入js【body末尾引入js文件会使页面加载更快】 -->
<th:block th:replace="pageFrame/basicsJs :: copy" />
<!-- bootstrapValidator -->
<script
th:src="@{/plugins/bootstrapValidator/js/bootstrapValidator.min.js}"></script>
<script th:src="@{/plugins/bootstrapValidator/js/language/zh_CN.js}"></script>
</body>
</html>
