SpringBoot工程創建過程

一、創建一個Maven工程，

在pom.xml文件中添加啓動依賴

<!--springboot要求，項目要繼承spring-boot-starter-parent起步依賴-->
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.8.RELEASE</version>
</parent>

<dependencies>
    <!--web功能，項目要繼承spring-boot-starter-web起步依賴-->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

創建引導類

package com.springboot;

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

/**
 * @Auther zhishuaijun
 * 這個啓動類的 名字叫什麼都可以
 * @Date 2019/10/25 11:21
 */
@SpringBootApplication
public class MySpringBootApplication {
    //psvm鍵+alt+Enter快速生成main
    public static void main(String[] args) {
        SpringApplication.run(MySpringBootApplication.class, args);
    }

}

創建controller

package com.springboot.controller;

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

/**
 * @Auther zhishuaijun
 * @Date 2019/10/25 11:47
 */
@Controller
public class SpringBootHelloController {

    @RequestMapping("/hello")
    @ResponseBody
    public String  hello(){
        return "hello SpringBoot";
    }
}

完成。瀏覽器輸入http://localhost:8080/hello

結果如下：
