package com.zs.helloword.controller;

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

// 在templates目录下的页面 只能通过controller来跳转
// 需要模板引擎的支持 thymeleaf
@Controller // 跳到一个页面
public class TestController {
    
    
    @RequestMapping("/test")
    public String test(Model model) {
