Spring系列之——使用模板快速搭建springboot项目

1 在官网https://start.spring.io/生成spring boot的模板

---

2 IDEA导入模板，设置如下勾选项，其他选项卡为默认值

---

3 idea呈现

---

4 新增controller类

package com.gbm.controller;

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

import java.util.HashMap;
import java.util.Map;

/**
 * Created by Administrator on 2019/2/20.
 */

@Controller
public class IndexController {
    @RequestMapping("/index")
    @ResponseBody
    public String index() {
        return "我爱北京天安门！";
    }
}

---

5 增加ComponentScan注解，并运行main方法（见下图，包含运行日志，本例子增加了spring security，故在运行日志中出现了一行“Using generated security password”）

package com.gbm.myspingboot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan(basePackages = {"com.gbm.controller"})
public class MyspingbootApplication {

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

}

6 任何浏览器上运行 http://localhost:8080/index

成功导入springboot！
