首先匯入thymeleaf:

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

使用:

只要把HTML頁面放在classpath:/templates/下, thymeleaf就能自動渲染

例如, 在resources目錄下:

　　resources目錄下建立hello.html

　　templates目錄下建立success.html

controller程式碼如下:

package com.ryan.springdemothymeleaf.controller;

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

@Controller
 
public class Hellocontroller {

    @ResponseBody
    @RequestMapping("/Hello")
    public String hello(){
        return "Hello World!";
    }

    @RequestMapping("/success")
    public String success(){
        return "success.html";
    }
}

在瀏覽器訪問 localhost:8080/hello.html 可訪問hello.html檔案

在瀏覽器訪問 localhost:8080/success 可訪問success.html檔案 (不新增.html)
