java web service 开发 具体实例

以一个工作中编写的安全域信息同步为例进行描述;
安全域信息同步其实就是一个XML文件的传输,WEB SERVICE 本质上就是通过XML进行数据的传输.
传输的XML格式如下:
  <?xml version="1.0" encoding="UTF-8" ?>
- <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
- <SOAP-ENV:Body>
- <simota:SynSecurityDomain xmlns:simota="http://www.chinamobile.com">
  <simota:SeqNum>1111</simota:SeqNum>
  <simota:SessionID>1111</simota:SessionID>
  <simota:SynType>01</simota:SynType>
- <simota:SecurityDomain>
  <simota:AppAID>123456789</simota:AppAID>
  <simota:InstallParams>222222</simota:InstallParams>
  <simota:MinAppSize>33</simota:MinAppSize>
  <simota:ManageMaxSize>44</simota:ManageMaxSize>
  <simota:ManageMinSize>55</simota:ManageMinSize>
  <simota:DomainType>66</simota:DomainType>
  <simota:DeleteRule>77</simota:DeleteRule>
  <simota:SIN>8</simota:SIN>
  <simota:TAR>99</simota:TAR>
  </simota:SecurityDomain>
  </simota:SynSecurityDomain>
  </SOAP-ENV:Body>
  </SOAP-ENV:Envelope>
 
 
根据该XML需要编写响应的解析类来接收XML文件传输过来的数据:
解析类如下:
package com.watchdata.raadtinterface.common.syn;
 
import org.jdom.Element;
import org.jdom.Namespace;
import org.apache.commons.logging.*;
import com.watchdata.raadtinterface.common.*;
 
public class SynSecurityDomainRequest
    implements BaseMsg {
  public SynSecurityDomainRequest() {
  }
 
  private String seqNum;
  private String sessionID;
  private String synType;
  private SecurityDomainBean securityDomain;
