springcloud.2.創建統一的依賴管理

現在springcloud總目錄下創建一個新的目錄hello-spring-cloud-dependencies用於做統一管理，新建一個pom文件
pom文件內容如下

<?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"

着重記錄下幾個比較重要的內容
用於繼承springboot的配置

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.3.RELEASE</version>
</parent>

packaging值爲pom，用於做全局性依賴的

<packaging>pom</packaging>

spring-cloud的版本，可以關注spring官網，選擇目標版本

<spring-cloud.version>Finchley.RELEASE</spring-cloud.version>

靜態資源文件目錄，打包的時候默認不會打包靜態資源文件，所以需要指定一下路徑，因爲.java文件不需要被打包，所以這裏用excludes去除一下

<resources>
    <resource>
        <directory>src/main/java</directory>
        <excludes>
            <exclude>**/*.java</exclude>
        </excludes>
    </resource>
    <resource>
        <directory>src/main/resources</directory>
    </resource>
</resources>

倉庫配置，具體想用什麼倉庫根據實際情況自己選擇，但是這其中包含spring的倉庫，添加它的原因是spring有時候發佈新功能發佈的是快照版本，不會直接將新功能發佈到中央庫中，但是會發布到spring自己的倉庫中，所以此處依賴是爲了能夠使spring新的依賴可以被下載

<repositories>
    <repository>
        <id>aliyun-repos</id>
        <name>Aliyun Repository</name>
        <url>http://maven.aliyun.com/nexus/content/groups/public</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>

    <repository>

        <releases>
            <enabled>false</enabled>
        </releases>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>

    <repository>
        <id>spring-snapshots</id>
        <name>Spring Snapshots</name>
        <url>https://repo.spring.io/snapshot</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
    <repository>
        <id>spring-milestones</id>
        <name>Spring Milestones</name>
        <url>https://repo.spring.io/milestone</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>

配置完後，添加託管，然後就完成了springcloud的統一依賴管理
