Spring Boot多模塊項目配置關聯（附打包jar/war方法）

一、父模塊的pom文件

<?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">
    <!-- 基本信息 -->
    <description>XXX項目</description>
    <modelVersion>4.0.0</modelVersion>
    <name>adapter</name>
    <packaging>pom</packaging>
    <!-- 項目說明：這裏作爲聚合工程的父工程 -->
    <groupId>com.cmcc</groupId>
    <artifactId>private_protocol_adapter</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <!-- 繼承說明：這裏繼承SpringBoot提供的父工程 -->

        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <!-- 模塊說明：這裏聲明多個子模塊 -->
    <modules>
        <module>station</module>
    </modules>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
    </properties>


</project>

二、子模塊pom文件

            <version>1.2.3</version>
        </dependency>
    </dependencies>
  
    </build>


</project>

三、打jar/war包方法

1）在pom文件中加入下面這部分代碼，如果想打war包就把打war包註釋打開，同時把打jar包的註釋掉

 <!-- 打包成war -->
   <!-- <packaging>war</packaging>-->
    <!-- 默認 -->
    <packaging>jar</packaging>

<!--將應用打包成可執行jar包-->
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

如果想將將本地所有依賴打包進去，填寫下面代碼

<build>
        <plugins>
            <!--添加maven插件-->
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <!--添加自己的啓動類路徑！-->
                <configuration>
                    <mainClass>com.cmcc.weatherstation.WeatherStationApplication</mainClass>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <!--可以把依賴的包都打包到生成的Jar包中-->
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

2）點擊父項目maven的clean進行清理

3）點擊父項目maven的package進行打包，打完包再target目錄下找到xxx.jar包即可
