这篇文章主要利用URLconnection调用webService接口，并利用dom4解析返回的数据
1.wsdl数据（访问http://localhost:8081/ERPDEMO/service/users?wsdl）
<wsdl:definitions xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://impl.service.demo.com/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:ns2="http://schemas.xmlsoap.org/soap/http" xmlns:ns1="http://service.demo.com/" name="UserServiceImplService" targetNamespace="http://impl.service.demo.com/">
<wsdl:import location="http://localhost:8081/ERPDEMO/service/users?wsdl=UserService.wsdl" namespace="http://service.demo.com/"></wsdl:import>
<wsdl:binding name="UserServiceImplServiceSoapBinding" type="ns1:UserService">
<soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="getPermissions">
<soap:operation soapAction="" style="document"/>
<wsdl:input name="getPermissions">
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output name="getPermissionsResponse">
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
<wsdl:operation name="selectByUserName">
<soap:operation soapAction="" style="document"/>
<wsdl:input name="selectByUserName">
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output name="selectByUserNameResponse">
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
<wsdl:operation name="login">
<soap:operation soapAction="" style="document"/>
<wsdl:input name="login">
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output name="loginResponse">
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
<wsdl:operation name="insert">
<soap:operation soapAction="" style="document"/>
<wsdl:input name="insert">
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output name="insertResponse">
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
<wsdl:operation name="getRoles">
<soap:operation soapAction="" style="document"/>
<wsdl:input name="getRoles">
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output name="getRolesResponse">
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
<wsdl:operation name="getUserById">
<soap:operation soapAction="" style="document"/>
<wsdl:input name="getUserById">
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output name="getUserByIdResponse">
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="UserServiceImplService">
<wsdl:port binding="tns:UserServiceImplServiceSoapBinding" name="UserServiceImplPort">
<soap:address location="http://localhost:8081/ERPDEMO/service/users"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>
2.利用soapui获得你所有方法的soap格式数据
3.开始写方法，我将调用方法和dom4j解析方法写在一起，后期再分开吧
public static void main(String[] args) throws Exception {
// WebService服务的地址
URL url = new URL("http://localhost:8081/ERPDEMO/service/users?wsdl");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
// 是否具有输入参数
conn.setDoInput(true);
// 是否输出输入参数
conn.setDoOutput(true);
// 发POST请求
conn.setRequestMethod("POST");
// 设置请求头（注意一定是xml格式）
conn.setRequestProperty("content-type", "text/xml;charset=utf-8");
String username = "csdn1";
// 构造请求体，符合SOAP规范（最重要的）
String requestBody = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:ser=\"http://service.demo.com/\" "
+ "xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">"
+ " <soapenv:Header/>"
+ " <soapenv:Body>"
+ "<ser:selectByUserName>"
+ "<userName>"
+ username
+ "</userName>"
+ "</ser:selectByUserName>"
+ " </soapenv:Header/>"
+ "</soapenv:Body>"
+ "</soapenv:Envelope>";
// 获得一个输出流
OutputStream out = conn.getOutputStream();
out.write(requestBody.getBytes());
// 获得服务端响应状态码
int code = conn.getResponseCode();
StringBuffer sb = new StringBuffer();
if (code == 200) {
// 获得一个输入流，读取服务端响应的数据
InputStream is = conn.getInputStream();
byte[] b = new byte[1024];
int len = 0;
while ((len = is.read(b)) != -1) {
String s = new String(b, 0, len, "utf-8");
sb.append(s);
}
is.close();
}
out.close();
System.out.println("服务端响应数据为：" + sb.toString());
// 初始化报文，调用parse方法，获得结果map，然后按照需求取得字段，或者转化为其他格式
Map map = new test01().parse(sb.toString());
// 获得字段的值;
String email = map.get("email").toString();
String id = map.get("id").toString();
String password = map.get("password").toString();
String roleid = map.get("roleid").toString();
String username1 = map.get("username").toString();
System.out.println("email==" + email);
System.out.println("id==" + id);
System.out.println("password==" + password);
System.out.println("roleid==" + roleid);
System.out.println("username1==" + username1);
}
dom4j解析方法
public Map<String, Object> map = new HashMap<String, Object>();
/**
* 解析soap
*
* @param soap
* @return
* @throws DocumentException
*/
public Map parse(String soap) throws DocumentException {
Document doc = DocumentHelper.parseText(soap);// 报文转成doc对象
Element root = doc.getRootElement();// 获取根元素，准备递归解析这个XML树
getCode(root);
return map;
}
/**
* 遍历
*
* @param root
*/
public void getCode(Element root) {
if (root.elements() != null) {
List<Element> list = root.elements();// 如果当前跟节点有子节点，找到子节点
for (Element e : list) {// 遍历每个节点
if (e.elements().size() > 0) {
getCode(e);// 当前节点不为空的话，递归遍历子节点；
}
if (e.elements().size() == 0) {
map.put(e.getName(), e.getTextTrim());
}// 如果为叶子节点，那么直接把名字和值放入map
}
}
}
下面是返回的数据
1.soap返回的数据格式
服务端响应数据为：<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<ns1:selectByUserNameResponse xmlns:ns1="http://service.demo.com/"><return>
<email>111qq.com</email>
<id>1</id>
<password>123</password><roleid>1</roleid><username>csdn1</username>
</return>
</ns1:selectByUserNameResponse></soap:Body>
</soap:Envelope>
2.dom4j解析后的结果
email==111qq.com
id==1
password==123
roleid==1
username1==csdn1
