spring maven项目解决依赖jar包版本冲突方案

在spring reference中提到一个解决spring jar包之间版本冲突的解决方案，原文如下

It is possible to accidentally mix different versions of Spring JARs when using Maven. For example, you may find that a third-party library, or another Spring project, pulls in a transitive dependency to an older release. If you forget to explicitly declare a direct dependency yourself, all sorts of unexpected issues can arise.

To overcome such problems Maven supports the concept of a "bill of materials" (BOM) dependency. You can import the spring-framework-bom in yourdependencyManagement section to ensure that all spring dependencies (both direct and transitive) are at the same version.

在配置spring项目依赖时可以通过引入spring-framework-bom避免项目中的spring jar包及关联依赖的三方jar包之间的版本冲突，引入方式：

<dependencyManagement>

    <dependencies>

        <dependency>

            <groupId>org.springframework</groupId>

            <artifactId>spring-framework-bom</artifactId>

            <version>4.1.3.RELEASE</version>

            <type>pom</type>

            <scope>import</scope>

        </dependency>

    </dependencies>

</dependencyManagement>

引入后的另一个好处就是在pom文件中引入spring相关依赖时不用再声明<version>属性，以后直接像下边这样声明就可以了：

<dependencies>

    <dependency>

        <groupId>org.springframework</groupId>

        <artifactId>spring-context</artifactId>

    </dependency>

    <dependency>

        <groupId>org.springframework</groupId>

        <artifactId>spring-web</artifactId>

    </dependency>

<dependencies>
