1、xml格式

<?xml version="1.0" encoding="utf-8"?>  
<MbfBody>   
    <tZmdifs319>    
		<cmmdtyCode>000000000183585090</cmmdtyCode>
		<DISTRIBUTE_SYS>FIMS,LOBA</DISTRIBUTE_SYS>
   </tZmdifs319>   
   <tZmdifs325>
    <cmmdtyCode>000000000183585090</cmmdtyCode>
    <businessField>PRMT_TMPL_CODE</businessField>
    <keywordCode>000001</keywordCode>
    <businessFieldDesc>0053749</businessFieldDesc>
   </tZmdifs325>
</MbfBody>

2、项目添加jar包

<dependency>
	<groupId>com.thoughtworks.xstream</groupId>
	<artifactId>xstream</artifactId>
	 <version>1.4.2</version>
</dependency>
