springcloud修改父和子pom檔案，實現統一管理

接著我上篇文章說：SpringCloud多模組開發

看過這篇文章的會發現我沒有去修改pom檔案，一個專案一個pom檔案，那麼我建立父目錄就沒有意義了。

看我這個pom是如此的簡陋。在看看子pom

那麼現在我要大刀闊斧的修改了。

 修改父pom檔案

第一步：加入

<!--父工程一定要加-->
    <name>toutiao_kuaishou_parent</name>
    <packaging>pom</packaging>
    <description>toutiao_kuaishou_parent</description>

第二步：引入子模組

<!--子模組工廠配置-->
    <modules>
        <module>ad_eureka_server</module>
        <module>ad_toutiao_download</module>
        <module>kuaishou_download</module>
    </modules>

第三步：父元件引入子元件相應的包

<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>ad.parent</groupId>
    <artifactId>toutiao_kuaishou</artifactId>
    <version>1.0-SNAPSHOT</version>

    <!--父工程一定要加-->
    <name>toutiao_kuaishou_parent</name>
    <packaging>pom</packaging>
    <description>toutiao_kuaishou_parent</description>

    <!--子模組工廠配置-->
    <modules>
        <module>ad_eureka_server</module>
        <module>ad_toutiao_download</module>
        <module>kuaishou_download</module>
    </modules>

    <properties>
        <java.version>1.8</java.version>
        <spring-cloud.version>Hoxton.SR8</spring-cloud.version>
    </properties>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.4.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

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

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
            <exclusions>
                <exclusion>
                    <groupId>org.junit.vintage</groupId>
                    <artifactId>junit-vintage-engine</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
    </dependencies>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

第四步：子元件刪除相應的包，並引入父元件

<?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">
    <modelVersion>4.0.0</modelVersion>

    <groupId>ad.eureka.server</groupId>
    <artifactId>ad_eureka_server</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>ad_eureka_server</name>
    <description>eureka server monitor</description>

    <!--父工程的依賴-->
    <parent>
        <groupId>ad.parent</groupId>
        <artifactId>toutiao_kuaishou</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>


    <dependencies>

    </dependencies>

</project>

其他2個子元件同理。

專案一訪問發現json變成了xml

這是由於spring-cloud-starter-netflix-eureka-server造成的，那就不把他放在公共父類上，讓他回到子專案裡

訪問好了
