Question

这是我的第一个Spring Boot示例，第一步。我在STS 3.8中创建了一个SpringBoot项目，如下所示：

档案 - ＆gt;新的Spring Starter项目
Dependecies - ＆gt;网络

我在src / main / java / com.first.boot

中创建了以下控制器

的IndexController 包com.first.boot;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class IndexController {

  @RequestMapping("/")
  public String index(){
    return "index";
  }
}

接下来，我在src / main / resources / templates中创建了视图index.html：

<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>Getting Started: Serving Web Content</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
  Welcome to your first Spring Boot Page
</body>
</html>

然后我将项目运行为：右键单击项目 - ＆gt;以 - ＆gt;运行Spring Boot App

控制台显示正确的映射和Tomcat启动信息

Mapped "{[/]}" onto public java.lang.String com.first.boot.IndexController.index()

Tomcat started on port(s): 8080 (http)

Started FirstSpringBootApplication in 4.096 seconds (JVM running for 4.843)

Initializing Spring FrameworkServlet 'dispatcherServlet'

FrameworkServlet 'dispatcherServlet': initialization started

FrameworkServlet 'dispatcherServlet': initialization completed in 64 ms

但是每当我在浏览器上运行localhost：8080时，我都会看到这个页面：

Whitelabel Error Page

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

There was an unexpected error (type=Not Found, status=404).
No message available

控制台没有错误。

添加以下依赖项解决了这个问题：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

Spring启动视图不起作用
