SpringBoot开发第1章,Ideal开发设

一、下载Idea安装,地址:https://www.jetbrains.com/idea/download/other.html,我使用的社区版

 

二、下载jdk,安装jdk,配置环境变量

          新建JAVA_HOME  系统变量,设置jdk安装路径

            再path变量中后面添加,%JAVA_HOME%\bin

            检查jdk是否安装成功,执行Java -version

          

λ java -version
java version  "1.8.0_231"
Java(TM) SE Runtime Environment (build 1.8.0_231-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.231-b11, mixed mode)

 

四、配置 maven ,

    1.    下载maven , https://archive.apache.org/dist/maven/maven-3/3.6.2/binaries/    
    2.   设置maven环境变量,再path后面添加 C:\software\apache-maven-3.6.2\bin ,测试是否正常

       

λ mvn  -v
Apache Maven 3.8.5 (3599d3414f046de2324203b78ddcf9b5e4388aa0)
Maven home: C:\software\apache-maven-3.8.5
Java version: 1.8.0_231, vendor: Oracle Corporation, runtime: C:\software\Java\jdk1.8.0_231\jre
Default locale: zh_CN, platform encoding: GBK
OS name:  "windows 10" , version:  "10.0" , arch:  "amd64" , family:  "windows"

3.   新建一个本地仓库地址,C:\software\localRepository

 设置conf/settings.xml配置文件,设置阿里云仓库和本地仓库

       

复制出来,设置本地仓库  
C: //software//localRepository

设置阿里云仓库,根据maven.aliyun.com帮助设置
  
  aliyunmaven
  *
  阿里云公共仓库
  https: //maven.aliyun.com/repository/public
  1.   设置ideal=》setting=maven仓库地址,

             

五、创建maven项目

   

 

六、手工搭建springboot项目,添加pom引用,让后加载

 

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.7.9</version>
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>

    </dependency>
</dependencies>

 

七、增加文件夹,输入如下代码

 

package example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@EnableAutoConfiguration
public class Example {

    @RequestMapping("/")
    String home(){
        return "HelloWolrd888";
    }
    public static  void main(String[] args){
        SpringApplication.run(Example.class,args);
    }
}

八、运行使用 mvn spring-boot:run 或者配置启动

 

九、输入网址HTTP local host:8088
