xml文件在项目下建resource/Parameters.xml

<?xml version="1.0" encoding="UTF-8"?>
<book>
   <Email>

       <to>
           <name>11</name>
           <name>11</name>
       </to>

       <username>11</username>

       <pwd>11</pwd>

       <subject>xml测试</subject>

       <msg>第一次xml测试</msg>
   </Email>
</book>
