解决方法：
把$TOMCAT_HOME/common/endorsed目录下的xercesImpl.jar，xml-apis.jar文件拷贝到当前应用系统的WEB-INF/lib目录
并在对应的
TransformerFactory tFactory = TransformerFactory.newInstance();
代码前加
System.setProperty("javax.xml.transform.TransformerFactory", "com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl");
