JBPM流程部署校验之java利用XSD校验XML

JBPM流程定义校验之java利用XSD校验XML

         上篇我们学习了在.net中怎样利用XSD来验证xml，今天我们来看一下在java中怎样实现利用xsd来校验xml！

         //xml和xsd是独立的文件，否则是内联文件
         if(xsdPath!=null&&xsdPath!=""){
             File schemaLocation = new File(xsdPath);

         }
         else{

         }

         }
