我正在寻找问题的解决方案。我将从一个示例开始:我们有一个返回 userData (userName + userAddress) 的 SOAP Web 服务,我正在使用 Web 服务代理来提取 UserData,但是我只想接收 userName - 这需要通过 DataPower 来完成出色地。如何做到这一点?我正在考虑添加另一个 Web 服务代理,但是如何将逻辑添加到只选择用户名的应用程序中?dp中是否有任何消息转换?

UsersCatalog.java(UserImpl 类有 2 个字段 - userName 和 userAddress + setter 和 getter 一次在字符串数组中设置/获取它们)
package wtp;
import javax.jws.WebMethod;
import javax.jws.WebService;
@WebService
public class UsersCatalog implements User{
public static final User userImpl = new UserImpl();
@Override
@WebMethod
public String[] getUserData() {
System.out.println("getUserData");
return userImpl.getUserData();
}
@Override
@WebMethod
public void setUserData(String userName, String userAddress) {
System.out.println("setUserData");
userImpl.setUserData(userName, userAddress);
}
}
我听说过一种叫做 datapower 中的消息转换的东西。如果我可以选择要返回的 xml 实体,这将变得如此简单。
我将添加更多内容以更好地指定我的需求:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soapenv:Body>
<getUserDataResponse xmlns="http://wtp">
<getUserDataReturn>John</getUserDataReturn>
<getUserDataReturn>New York</getUserDataReturn>
</getUserDataResponse>
</soapenv:Body>
</soapenv:Envelope>
这就是我收到的,我希望 DataPower 以某种方式对其进行转换以仅返回第一行 - 仅返回用户名 John。如何收到这样的结果?
