Spring初始化创建JMS工厂出错

前段时间公司新启动一个项目，在前期的架构搭建的时候不是怎么理想。于是，本人决定进行项目重构。花了一周时间，独立完成了。在此分享一下在这整个重构过程中遇到的问题以及解决方案。

在重构接近尾声的时候，发现spring在初始化创建jms工厂的时候，bean工厂始终创建失败；困扰我一下午时间。

最终在进行代码跟踪的时候，发现activemq-pool 的版本号是5.7.0，它依赖的commons-pool的版本号是1.6；而当前工程的commons-dbcp依赖的commons-pool的版本号是1.5.4；openjpa-kernelok依赖的commons-pool的版本号是1.3；ok，问题原因找到了。接下来，就是去解决问题。
解决方案：
在maven依赖中排除不需要的版本。

          <dependency>
            <groupId>commons-dbcp</groupId>
            <artifactId>commons-dbcp</artifactId>
            <version>1.4</version>
            <!-- 排除不需要的版本  start -->
            <exclusions>
                <exclusion>
                    <groupId>commons-pool</groupId>
                    <artifactId>commons-pool</artifactId>

            </exclusions>
            <!-- 排除不需要的版本  end -->
        </dependency>
