java极简maven项目

因学习自动化软件发布，发现大部分项目都是java，故总结了一下新建一个简单的java的maven项目的过程，方便后面快速搭建一个测试项目，用于软件发布测试。

1、安装需要的软件

2、系统环境变量配置

系统–高级系统设置–高级–环境变量

3、用idea软件创建工程

C:\idea\bin\idea64.exe

创建工程后情况

4、编写代码

4.1、Main.java

src/main/java/org/example/Main.java

packageorg.example;importorg.springframework.beans.factory.annotation.Value;importorg.springframework.boot.SpringApplication;importorg.springframework.boot.autoconfigure.SpringBootApplication;importorg.springframework.web.bind.annotation.RequestMapping;importorg.springframework.web.bind.annotation.ResponseBody;importorg.springframework.stereotype.Controller;@Controller@SpringBootApplicationpublicclassMain{@Value("${test.env}")privateStringenv;@Value("${test.db}")privateStringdb;@RequestMapping("/hello")@ResponseBodypublicStringhome(){return"env:"+env+"/hello, db:"+db;}publicstaticvoidmain(String[]args){SpringApplication.run(Main.class,args);}}

4.2、pom.xml

<projectxmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>org.example</groupId><artifactId>javademo</artifactId><version>0.0.1-SNAPSHOT</version><packaging>jar</packaging><name>javademo</name><description>Spring Boot Demo</description><!-- Spring Boot 父工程 --><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>3.2.5</version><relativePath/></parent><properties><java.version>17</java.version></properties><dependencies><!-- Web / MVC / Controller / Tomcat --><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency></dependencies><build><plugins><!-- 让 java -jar 可运行 --><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

4.3、配置文件

4.3.1、application-prd.yml

src/main/resources/application-prd.yml test: env: prd-env db: prd-db

4.3.2、application-test.yml

src/main/resources/application-test.yml test: env: test-env db: test-db

5、用maven修复所有的错误提示

5.1、创建idea的maven本地仓库目录

C:\Users\Administrator\.m2\repository

5.2、准备idea的maven用户设置文件settings.xml

C:\Users\Administrator\.m2\settings.xml

<settingsxmlns="http://maven.apache.org/SETTINGS/1.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd"><!-- 使用内网 Nexus 作为所有仓库的镜像 --><mirrors><mirror><id>nexus</id><name>Internal Nexus Repository</name><url>http://10.1.1.1:8081/nexus/content/groups/public/</url><mirrorOf>*</mirrorOf></mirror></mirrors></settings>

5.3 配置maven库

5.4 用maven库修复错误提示

在idea的右侧点击maven图标，点刷新按钮，选中重新加载所有Maven项目，修复所有问题

6、手动编译

mvn clean package -DskipTests

7、手动编译成功情况

PS C:\Users\Administrator\IdeaProjects\javademo>mvn clean package-DskipTests [INFO] Scanningforprojects...

8、启动生产环境

java -jar javademo-0.0.1-SNAPSHOT.jar --spring.profiles.active=prd

9、启动测试环境
