1.首先在pom文件中引入模板引擎jar包，即
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency>
2.在application.properties中配置模板引擎
spring.thymeleaf.prefix=classpath:/templates/
是让controller层到templates文件夹寻找xx.html(src/main/resources/templates)
3.在templates下建立index.html文件
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8"/>
<title>Title</title>
</head>
<body>
<h1>123456789</h1>
</body>
</html>
4.controller层
package com.example.demo.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
/**
* Created by kemp on 2018/8/15.
*/
@Controller
public class MyController {
@RequestMapping("/test")
public String test(){
return "index";
}
}
注意：@controller不是@RestController，使用@RestController会返回“index”字符串
5.在浏览器中地址栏输入：http://localhost:8080/test
