3.1-1 dependencyManagement the type as pom usage

 

In Chapter 3 Example: Component confsvr spmia-chapter3-master of an example:

Pom file its contents are summarized as follows:

 

  <parent>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-parent</artifactId>

    <version>1.4.4.RELEASE</version>

  </parent>

  <dependencyManagement>

    <dependencies>

      <dependency>

        <groupId>org.springframework.cloud</groupId>

        <artifactId>spring-cloud-dependencies</artifactId>

        <version>Camden.SR5</version>

        <type>pom</type>

        <scope>import</scope>

      </dependency>

    </dependencies>

  </dependencyManagement>

 

  <dependencies>

    <dependency>

      <groupId>org.springframework.cloud</groupId>

      <artifactId>spring-cloud-config-server</artifactId>

    </dependency>

 

    <dependency>

      <groupId>org.springframework.cloud</groupId>

      <artifactId>spring-cloud-starter-config</artifactId>

    </dependency>

  </dependencies>

 

We use the idea to import the project, the subproject open pom.xml file, and then select "show effective pom" Right, this will open a window called "configurationserver-effective-pom.xml" of.

The above <scope> import </ scope> shows a version introduced come Camden.SR5 dependent spring-cloud-dependencies pom corresponding file information.

So window called "configurationserver-effective-pom.xml" in <dependencyManagement> element will pom.xml open to expansion, so there will be a lot of content.

 

We analyze window called "configurationserver-effective-pom.xml" in <dependencyManagement> The final version of the content and number two dependencies in pom.xml element declaration:

  <dependencies>

    <dependency>

      <groupId>org.springframework.cloud</groupId>

      <artifactId>spring-cloud-config-server</artifactId>

      <version>1.2.2.RELEASE</version>

      <scope>compile</scope>

    </dependency>

    <dependency>

      <groupId>org.springframework.cloud</groupId>

      <artifactId>spring-cloud-starter-config</artifactId>

      <version>1.2.2.RELEASE</version>

      <scope>compile</scope>

    </dependency>

  </dependencies>

You will find <dependencyManagement> for version management is not only dependent on the sub-project, but also for version management of its own projects where the dependent.
