我在用着spring boot和thymeleaf查看引擎。
问题是控制器没有显示正确的 html 页面，并且总是显示Whitelabel Error Page.
控制器：
package com.example.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class GifController {
@RequestMapping("/greeting")
public String sayhello() {
return "greets";
}
}
resources/templates 路径中的greets.html 文件：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8"/>
<title>Insert title here</title>
</head>
<body>
Hello!
</body>
</html>
also:
@EnableAutoConfiguration
@SpringBootApplication
@ComponentScan
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
还有 pom.xml ：
<?xml version="1.0" encoding="UTF-8"?>

问题出在哪里？当我浏览到localhost:8080/greeting表明whitelabel Error page而不是greets.html.
