spring boot访问html页面

首先,需要在pom.xml中增加 thymeleaf 的依赖

在resources目录下面的结构;

上图中的js,css,图片等需要放在static目录下面

spring boot中在static目录下面的资源是可以直接通过浏览器地址栏来访问的

也就是上图中的index.html,可以直接通过地址栏访问

http://localhost:8080/index.html

但是,如果将html页面放到templates目录下面,就需要通过controller跳转来访问了,类似WEB-INF目录

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";  //这里也可以写  "/login"
    }

}

此时访问路径:

http://localhost:8080/hello
