1、在Web專案開發程序中，錯誤資訊提示頁是一個重要的組成部分，為了不讓用戶直接看見例外資訊的頁面，此時，就需要有一個錯誤資訊提示頁，錯誤頁面一般都屬于靜態頁面，這里在src/main/resources/static目錄下創建error-404.html，
首先，在pom.xml里面新增幾個配置，在src/main/resources目錄下面要加下，不然無法進行加載，修改完畢之后，maven -> Update Project一下，
1 <?xml version="1.0" encoding="UTF-8"?>
2 <project xmlns="http://maven.apache.org/POM/4.0.0"

搞一個html靜態界面放到src/main/resources/static下面，如下所示：
1 <!DOCTYPE html>
2 <html>
3 <head>
4 <meta charset="UTF-8">
5 <title>Insert title here</title>
6 </head>
7 <body>
8
9 <img alt="錯誤頁面" src="images/error.jpg">
10
11 </body>
12 </html>
建立錯誤頁配置，springboot2.x此類EmbeddedServletContainerCustomizer已經被替換為WebServerFactoryCustomizer，如下所示：
1 package com.demo.config;
2
3 import org.springframework.boot.web.server.ConfigurableWebServerFactory;
4 import org.springframework.boot.web.server.ErrorPage;
5 import org.springframework.boot.web.server.WebServerFactoryCustomizer;
6 import org.springframework.context.annotation.Bean;
7 import org.springframework.context.annotation.Configuration;
8 import org.springframework.http.HttpStatus;
9
10 /**

12 * @author
13 *
14 * springboot2.x此類EmbeddedServletContainerCustomizer已經被替換為WebServerFactoryCustomizer
15 *
16 */
17 @Configuration
18 public class ErrorPageConfig {
19
20 @Bean
21 public WebServerFactoryCustomizer<ConfigurableWebServerFactory> webServerFactoryCustomizer() {
22 WebServerFactoryCustomizer<ConfigurableWebServerFactory> customizer = new WebServerFactoryCustomizer<ConfigurableWebServerFactory>() {
23
24 @Override
25 public void customize(ConfigurableWebServerFactory factory) {
26 // 定義404錯誤頁
27 HttpStatus notFound = HttpStatus.NOT_FOUND;
28 System.out.println(notFound);
29 // 定義404錯誤頁
30 ErrorPage errorPage404 = new ErrorPage(notFound, "/error-404.html");
31 // 追加錯誤頁，替換springboot默認的錯誤頁
32 factory.addErrorPages(errorPage404);
33 // 設定tomcat服務器的埠號
34 factory.setPort(8081);
35 }
36
37 };
38 return customizer;
39 }
40
41 }
配置完錯誤頁之后，會根據用戶請求時的http狀態碼跳轉到不同的頁面進行顯示，
運行效果，如下所示：
