SpringBoot多模块开发且只打包一个jar就可运行

新建SpringBoot主项目

新建SpringBoot主项目并删除多余文件，只留下pom.xml文件

pom.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="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 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.7.8</version><relativePath/> <!-- lookup parent from repository --></parent><groupId>com.tigerlau</groupId><artifactId>Test</artifactId><version>0.0.1-SNAPSHOT</version><packaging>pom</packaging><name>Test</name><description>Test</description><modules><module>module1</module><module>moudle2</module></modules><properties><java.version>1.8</java.version><moules2.version>0.0.1-SNAPSHOT</moules2.version><mybatis-plus.version>3.5.2</mybatis-plus.version><mysql.version>8.0.30</mysql.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><dependencyManagement><dependencies><dependency><groupId>com.tigerlau</groupId><artifactId>moudle2</artifactId><version>${moules2.version}</version></dependency><dependency><groupId>com.baomidou</groupId><artifactId>mybatis-plus-boot-starter</artifactId><version>${mybatis-plus.version}</version></dependency><dependency><groupId>com.baomidou</groupId><artifactId>dynamic-datasource-spring-boot-starter</artifactId><version>${mybatis-plus.version}</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>${mysql.version}</version></dependency></dependencies></dependencyManagement></project>
