spring boot的基本配置——spring boot的web开发——Thymeleaf模板引擎———接收数据并通过Model model的model.addAttribute返回数据给模板 

package com.test.controller;

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

import javax.servlet.http.HttpServletRequest;

@Controller
public class StartMainController
{
    @RequestMapping("/1")
    public String home1()
    {
        return "hello";
    }

    @RequestMapping("/2")
    @ResponseBody
    public String home2()
    {
        return "123";
    }

    @RequestMapping("/3")
    public String home3(Model model)
    {

        model.addAttribute("a","123");

        model.addAttribute("b","abc");

        model.addAttribute("c","def");

        return "hello";

    }

    @RequestMapping(value = "/4")
    public String home4(HttpServletRequest request, Model model)
    {
        String firstName = request.getParameter("firstName");

        System.out.println(firstName);

        model.addAttribute("firstName",firstName);

        return "hello";

    }

}
