异常输出：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

   ......

         <user>
               <type>100</type>
               <value>none</value>
         </user>
         <user>
                 <type>101</type>
                 <value>ok</value>
          </user>
</users>
...............
...............
</test>

但它只返回一个用户值：

   <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<test>
   ......
  <users>
         <user>
               <type>100</type>
               <value>none</value>
         </user>
</users>
...............
...............
</test>

如何解决这个问题？有人可以帮助我我做错了什么吗？

谢谢

修复这样的代码

    Test1 user1=new Test1();
    user1.setType("100");
    user1.setValue("none");

    Test1 user2=new Test1();
    user2.setType("101");
    user2.setValue("ok");

    ArrayList<Test1> permfile=new ArrayList<Test1>();
    permfile.add(user1);
    permfile.add(user2);
