【问题描述】：
我正在尝试渲染一个只有一个 h1 标记的 html .jsp...感觉它应该可以工作，但它没有。
如何让 index.jsp 文件呈现到我的浏览器中？请帮忙！
我正在使用： Maven 3.5.4 Java 1.8.0_181 STS 版本：3.9.5.RELEASE
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib prefix = "c" uri = "http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<h1> hello</h1>
</body>
</html>
我成功登录到被命中的路由，但 index.jsp 没有被读取。
package com.coding.test1;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@SpringBootApplication
@Controller
public class Test1Application {
public static void main(String[] args) {
SpringApplication.run(Test1Application.class, args);
}
@RequestMapping("/")
public String index() {
System.out.println("+++++hit main+++++++");
return "index.jsp";
}
}

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

编辑： 添加 ServletInitializer.java
package com.coding.test1;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
public class ServletInitializer extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Test1Application.class);
}
}

【问题讨论】：
-
您是否尝试删除包 com.coding.test1 中的 @Controller？
-
将此
return "index.jsp"更改为return "index" -
@Hana 刚刚尝试过，结果是它没有击中路线。
-
@NicholasK 刚刚尝试过，它仍然成功了，但我没有使用 .jsp 的后缀，所以最终这可能行不通？
-
向我们展示
ServletInitializer类在您的项目中的作用。 @NicholasK 提出的解决方案应该可行。
