首先,需要在pom.xml中增加 thymeleaf 的依賴

在resources目錄下面的結構;

上圖中的js,css,圖片等需要放在static目錄下面

spring boot中在static目錄下面的資源是可以直接通過瀏覽器位址列來訪問的

也就是上圖中的index.html,可以直接通過 位址列訪問

http://localhost:8080/index.html

但是,如果將html頁面放到templates目錄下面,就需要通過controller跳轉來訪問了,類似WEB-INF目錄

package com.tencent.erweimaweb.com.tencent.erweima.controller;

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


@Controller
public class ErweimaController {
    
    /**
     * @param
     * @return
     */
    @RequestMapping("/hello")
    public String helloHtml() {
        System.out.println("hello world!");
        return "login";  //這裡也可以寫  "/login"
    }

}
 

此時訪問路徑:

http://localhost:8080/hello
