java.util.collection 从 web 服务返回

Question

我正在调用一个服务，该服务将我作为 java.util.Collection 的输出参数返回。现在我的问题是如何从该对象检索数据？如果我用 Java 打印它，我会得到类似 [[Ljava.lang.Object;@7ff4d7c0] 的内容。这很正常，因为我只是打印对象。

该服务来自 ofbiz 项目，并且运行正常。当我使用 ofbiz 的网络服务测试器时，我得到的返回值为:

{{party=[GenericEntity:Party][partyId,10045(java.lang.String)][partyTypeId,PERSON(java.lang.String)]}, {party=[GenericEntity:Party][partyId,10119(java.lang.String)][partyTypeId,PERSON(java.lang.String)]}}` 

如何在 Java 中实现此目的？

这是我的代码:

public static void main(String[] args) throws MalformedURLException, XmlRpcException {


    XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
    config.setServerURL(new URL("http://127.0.0.1:8080/webtools/control/xmlrpc"));
    config.setEnabledForExceptions(true);
    config.setEnabledForExtensions(true);

    XmlRpcClient client = new XmlRpcClient();
    client.setConfig(config);

    Map paramMap = new HashMap();
    Map map1 = new HashMap();


    //Verplichte parameters
    paramMap.put("login.username", "admin");
    paramMap.put("login.password", "opentaps");
    paramMap.put("userLoginId", "David");

    Object[] params = new Object[]{paramMap};

    Map result = (Map) client.execute("getPartyFromUserLogin", params);
    //System.out.println(result.values());


    Collection parties = null;
    parties = (Collection) result.values();
    System.out.println("Got parties: " + parties.size());
    System.out.println(parties.toString());


    Iterator it = parties.iterator();
    while(it.hasNext()){
        Party object = (Party)it.next();
        System.out.println("ok : "+ object.getPartyId());
    }

}

好的，现在我尝试迭代它并将其转换为 Party 对象(import org.opentaps.base.entities.Party;)。猜猜它只是转换到了错误的类？

错误日志:

Exception in thread "main" java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to org.opentaps.base.entities.Party
    at test.xmlrpcGetPartyEmail.main(xmlrpcGetPartyEmail.java:56)

使用此代码后的错误日志:

    Iterator it = parties.iterator();
while(it.hasNext()){
    System.out.println("ok : "+ it.next().getClass());
}

class java.util.HashMap$Values
Got parties: 1
[[Ljava.lang.Object;@2380bfe1]
ok : class [Ljava.lang.Object;

你可以尝试运行你的程序吗

Iterator it = parties.iterator();
while(it.hasNext()){
    System.out.println("ok : "+ it.next().getClass());
}

并发布结果？
