SpringBoot入门小案例

Posted 2021-01-21 cppdy

1、创建一个简单的maven project项目

2、下面来看一下项目结构：

3、pom.xml 配置jar包

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.9.RELEASE</version>
    <relativePath/>
</parent>
  
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>    

pom.xml

4、创建一个SpringBoot项目运行的启动类

package com.cppdy;

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

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

}

Application

5、创建一个controller

package com.cppdy.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloWordController {
    
    @RequestMapping("hello")
    public String hello() {
        
        return "HelloWord";
    }

}

HelloWordController

6、到这一步项目就配置好了打开浏览器输入就可以访问了，请注意访问不需要加项目名，如果要加需要在application.properties文件中另行配置
