解决方案：

自从使用了 esapi 之后，系统启动第一次访问都会出现 下面的log 异样，并且第一次访问会出现错误页面

查了相关文档，http://mzlly999.iteye.com/blog/1189899

说 xerces 版本过低

看了下，正式环境 :

xercesImpl 才 2.6.2

指定更新的xercesImpl版本：

<dependency>      <groupId>xerces</groupId>      <artifactId>xercesImpl</artifactId>      <version>2.10.0</version>  </dependency>  

问题解决。
