webservice--解析xml 客户端请求的xml格式:
<?xml version="1.0" encoding="utf-8" ?>
<selectPage>
<start></start>
<end></end>
</selectPage>
服务器响应的xml格式:
<?xml version="1.0" encoding="utf-8" ?>
  <selectPage>
    <accountName></accountName>
</selectPage>
服务端
实体：
package l.entity;
import java.io.Serializable;
public class Account implements Serializable {
private Integer accountNo;
private String accountName;
private String password;
private Integer balance;
//private java.util.Date openDate;
public Integer getAccountNo() {
return accountNo;
}
public void setAccountNo(Integer accountNo) {
this.accountNo = accountNo;
}
public String getAccountName() {
return accountName;
}
public void setAccountName(String accountName) {
this.accountName = accountName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public Integer getBalance() {
return balance;
}
public void setBalance(Integer balance) {
this.balance = balance;
}
使用dom4j解析xml文件
public Account(Integer accountNo, String accountName, String password,
Integer balance) {
super();
this.accountNo = accountNo;
this.accountName = accountName;
this.password = password;
this.balance = balance;
}
public Account() {
super();
}
@Override
public String toString() {
return "Account [accountNo=" + accountNo + ", accountName="                + accountName + ", password=" + password + ", balance="                + balance + "]";
}
}
实现类：

import java.util.List;
import javax.jws.WebService;
l.ws.WebFault;
import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import l.dao.AccountDao;
import l.dao.AccountDaoImpl;
import l.entity.Account;

@WebService
public class AccountServiceImpl implements AccountService { private AccountDao ad = new AccountDaoImpl();
@Override
public String selectPage(String info) throws Exception {
//解析请求的xml
Account account = parseXml(info);
int start = AccountNo()-1;  //起始下标
int end = Balance()-start;  //记录数
//查询区域列表
List<Account> list = ad.selectPage(start, end);
//解析list响应为客户端
String psrseList = psrseList(list);
return psrseList;
}
//解析请求的xml
private Account parseXml(String info) throws Exception{
Account account = new Account();
//使⽤dom4j解析
Document document=null;
try {
document = DocumentHelper.parseText(info);
} catch (Exception e) {

}
String start = document.selectSingleNode("selectPage/start").getText();
String end = document.selectSingleNode("selectPage/end").getText();
account.setAccountNo(Integer.parseInt(start));
account.setBalance(Integer.parseInt(end));
return account;
}
//解析list，响应回去
private String psrseList(List<Account> list){
Document document = ateDocument();
Element root = ateElement("areas");
//添加根节点
document.add(root);
for (Account account : list) {
String accountName = AccountName();
root.addElement("accountName").addText(accountName);
}
return document.asXML();
}
}
