Springboot的pom文件配置

Springboot 提供的jar中封装了相关的常用jar，使得配置更加简单，引用关系更加清晰。下面就说明下 Springboot 的 pom 配置。
先来看下项目的结构：
（这个项目是用来实现SSO和权限认证的，但是权限部分还不全，之后会附上源码，感兴趣的朋友可以下载。）

下面先说明一下项目总的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 http://maven.apache.org/maven-v4_0_0.xsd">

  <!--parent的引用是固定的-->
  <parent>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-parent</artifactId>
      <version>1.5.9.RELEASE</version>
  </parent>

  <modelVersion>4.0.0</modelVersion>
  <packaging>pom</packaging>

  <groupId>com.mljr.sharp</groupId>
  <artifactId>sharp-sso-all</artifactId>
  <version>1.0.0-SNAPSHOT</version>

  <!--项目包含的模块，这个配置是有顺序的，决定了模块编译时的顺序-->
  <modules>
    <module>sharp-sso-api</module>
    <module>sharp-sso-core</module>
    <module>sharp-sso-web</module>
  </modules>

  <!--给出Maven部署当前项目的构件到远程库时，关于远程库的配置-->
  <distributionManagement>
    <repository>
      <id>releases</id>
      <name>Nexus Release Repository</name>
      <url>http://maven.xxxxx.com/content/repositories/releases/</url>
    </repository>
    <snapshotRepository>
      <id>snapshots</id>
      <name>Nexus Snapshot Repository</name>
      <url>http://maven.xxxxx.com/content/repositories/snapshots/</url>
    </snapshotRepository>
  </distributionManagement>

</project>

可以看到根目录的pom文件的配置非常简单，这里没有配置其他的依赖包，大家可以根据自己的需要自行配置。不过建议大家哪个模块用了依赖包就在哪个模块配置，这样引用关系比较明确，不要在根目录的pom里配置，子模块在引用其他依赖包的时候很可能会与继承的依赖包产生冲突。

下面是 api 模块的pom文件，api中引入的都是在api中常用的jar，非常简单：

下面是 core 模块的配置文件，引入的 jar 比较多，该模块负责对外服务的核心实现 ，包含了对数据源、mybatis、dubbo 等的配置。
