spring-boot4代码

App.java

package com.kfit;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class App {

    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }
}

HelloController.java

package com.kfit;

import java.util.Map;

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

@Controller
public class HelloController {
    
    @RequestMapping("/index")
    public String index(Map<String,Object> map){
        map.put("name", "Andy");
        return "index";
    }
}

总结.txt

1、新建一个maven web project;

2、在pom.xml文件中添加相应的依赖包；

3、新建一个HelloController请求控制类；

4、编写index.jsp页面；

5、编写启动类App.java

6、启动应用程序进行代码测试
