Map==>xml测试结果

public static void main(String[] args) {
    
    
  HttpUtils http = new HttpUtils();
  Map<String,Object> Input = new HashMap<String,Object>();
  Map<String,Object> InHead = new HashMap<String,Object>();
  Map<String,Object> InBody = new HashMap<String,Object>(); 
  
  InHead.put("BusinessNumber", "BusinessNumber");
  InHead.put("TerminalNumber", "TerminalNumber");
  InHead.put("CooperationUnit", "CooperationUnit");
  InBody.put("PatientId", "PatientId");
  InBody.put("BillNo", "BillNo");
  InBody.put("BillMethod", "BillMethod");
  InBody.put("Price", "Price");
  InBody.put("PatientId","PatientId");
  
  Input.put("InHead", InHead);
  Input.put("InBody", InBody);
  Map<String,Object> xmlmap = new HashMap<String,Object>();
  xmlmap.put("Input", Input);
  System.out.println(http.mapToXmlFormatString(xmlmap));

结果：

<?xml version="1.0" encoding="utf-8"?><Input><InHead><BusinessNumber>BusinessNumber</BusinessNumber><CooperationUnit>CooperationUnit</CooperationUnit><TerminalNumber>TerminalNumber</TerminalNumber></InHead><InBody><BillNo>BillNo</BillNo><BillMethod>BillMethod</BillMethod><Price>Price</Price><PatientId>PatientId</PatientId></InBody></Input>

格式化后：

<?xml version="1.0" encoding="utf-8"?>
<Input>
    <InHead>
        <BusinessNumber>BusinessNumber</BusinessNumber>
        <CooperationUnit>CooperationUnit</CooperationUnit>
        <TerminalNumber>TerminalNumber</TerminalNumber>
    </InHead>
    <InBody>
        <BillNo>BillNo</BillNo>
        <BillMethod>BillMethod</BillMethod>
        <Price>Price</Price>
        <PatientId>PatientId</PatientId>
    </InBody>
</Input>
