*  src/main/java 程序开发以及主程序入口
 *  src/main/resources 配置文件以及view层的显示页面文件
 *  src/test/java 测试程序

4.在src/main/java 目录下新建com.example.bean包，在该包下新建Person.java文件。

package com.example.bean;
    
    public class Person {
    	private String name;
        private Integer age;
        public Person() {
        	super();
        }
        public Person(String name,Integer age) {
        	super();
        	this.name=name;
        	this.age=age;
        }
    	public String getName() {
    		return name;
    	}
    	public void setName(String name) {
    		this.name = name;
    	}
    	public Integer getAge() {
    		return age;
    	}
    	public void setAge(Integer age) {
    		this.age = age;
    	}
        
        
    }

5.打开com.example.demo包下的SpringbootTest2Application.java文件，添加代码如下图所示。

package com.example.demo;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import com.example.bean.Person;
    @Controller
    @SpringBootApplication
    public class SpringbootTest2Application {
    
    	public static void main(String[] args) {
    		SpringApplication.run(SpringbootTest2Application.class, args);
    	}
    	@RequestMapping("/")
    	public String index() {
    		
    		return "index";
    	}
    	
    	@RequestMapping("userLogin")
    	public String userLogin(Model model) {
    		Person p=new Person("yxc",20);
    		model.addAttribute("user", p);
    		return "userLogin";
    	}
    }

6.在src/main/resources 目录下的templates文件下新建index.html和userLogin.html.

index.html

<!DOCTYPE html>
    <html>
    <head>
    <meta charset="UTF-8">
    <title>Insert title here</title>
    </head>
    <body>
    <p1> this is my first springboot project</p1>
    <a href="/userLogin">west world</a>
    </body>
    </html>

userLogin.html

<html  xmlns:th="http://www.thymeleaf.org">
    <html>
    <head>
    <meta charset="UTF-8">
    <title>Insert title here</title>
    </head>
    <body>
    welcome to west world
    <span th:text="${user.name}"></span>
    </body>
    </html>

7.启动主程序，打开浏览器访问http://localhost:8080
