  • spring maven项目解决依赖jar包版本冲突方案

    引入:http://blog.csdn.net/sanzhongguren/article/details/71191290

    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>
