我正在尝试创建一个简单的Web服务,它将String作为输入并返回字符串作为输出。 我正在使用Ecelipse Helios和Axis 2.15。

事实上我正在使用XStream和Client / WebService。
对于Web服务框架,
代码就像这样:
public com.url.pkg.ShowInputResponse showInput(
com.url.pkg.ShowInput showInput) {
// TODO : fill this with the necessary business logic
String inputString = showInput.getInputString();
System.out.println("INput String is :\n" + inputString);
XStream xStream = new XStream();
System.out.println("After XStream Declaration...");
SOVO vo = null;
try {
vo = (SOVO) xStream.fromXML(inputString);
} catch (Throwable e) {
System.out.println(e);
e.printStackTrace();
}
System.out.println("After SOVO casting from XML");
System.out.println(vo.getName());
System.out.println(vo.getParams());
// TODO: business logic
ShowInputResponse response = new ShowInputResponse();
response.set_return(inputString);
return response;
}
我的客户端代码是这样的:
public static void main(String[] args) throws Exception {
BasicServiceStub stub = new BasicServiceStub();
ShowInput request = new ShowInput();
SOVO sovo = new SOVO();
sovo.setName("I am the post for SO");
Map params = new HashMap();
params.put("key1", "val1");
params.put("key2", "val2");
sovo.setParams(params);
XStream xStream = new XStream();
String soVoString = xStream.toXML(sovo);
// System.out.println(soVoString);
request.setInputString(soVoString);
ShowInputResponse response = stub.showInput(request);
System.out.println("....................................");
System.out.println("response = " + response.get_return());
}
SOVO是一个简单的POJO,它存在于客户端和Web服务端。
public class SOVO {
private String name;
private Map params;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Map getParams() {
return params;
}
public void setParams(Map params) {
this.params = params;
}
}
最后但最重要的WSDL就在这里:

我必须修改异常的堆栈跟踪:
我不确定它是否会访问网络服务层。

看起来更像是XStream desirialization的一些问题。尽管SOVO在类路径中为什么会发生?我错过了什么吗?
当我尝试将XXXXX作为字符串发送时,它会告诉:
在开始标记之前只允许空白内容而不是X(位置:START_DOCUMENT看到X ... @ 1:1)
当我尝试发送“某些价值”时,它说:
在开始标记之前只允许空白内容而不是s(位置:START_DOCUMENT看到s ... @ 1:1)
我不确定是什么问题。
答案 0 :(得分:2)
我建议如下:
使用其他客户端测试服务
使用soapUI为您的showInput
方法生成有效的测试请求。如果您使用此工具没有收到任何错误,您就知道您的服务正常运行。如果您做收到错误,那么您就知道要开始在服务代码中进行挖掘。
启用SOAP消息的客户端日志记录
运行客户端时添加以下JVM选项:
-Dorg.apache.commons.logging.Log=org.apache.commons.logging.impl.SimpleLog
-Dorg.apache.commons.logging.simplelog.showdatetime=true
-Dorg.apache.commons.logging.simplelog.log.httpclient.wire=debug
-Dorg.apache.commons.logging.simplelog.log.org.apache.commons.httpclient=debug
这将让您看到传输的SOAP消息。密切关注在您的开始标记之前出现的内容,如错误消息所示。
