Failed to introspect annotations: interface com.xxx

在使用maven打包发布项目时发现在tomcat容器中正常启动！后来需要DEUG调试程序，在eclipse中使用了插件在Jetty中启动报错，当时纳闷了一下，why！？

错误信息：

查看了jetty容器启动过程输出的日志，发现它在加载一个依赖项目时，spring版本和其它项目的版本不一致，发现后将其版本改成统一版本，重新启动，正常了！

所以，在使用maven构建项目时，应该建立父子项目，所有子项目的jar包都应交给父项目管理，即能保证jar包统一，同时方便升级！

以下问题也是版本（xerces）不统一造成：
