我想創建一個簡單的webservice,它將一個字符串作爲輸入並返回字符串作爲輸出。 我使用Ecelipse Helios和Axis 2.15。使用XStream通過電線發送字符串的反序列化問題
- 我正在爲此編寫簡單的WSDL。
- 我正在使用代碼生成器生成存根。
新建 - >代碼生成器 - > java類從wsdl->給WSDL並生成java骨架。
- 而在skelton中,我只是將值作爲參數打印出來。並返回相同的值。
- 我寫了客戶端代碼來調用webservice的方法。這需要一個字符串。
- 但當我試圖調用該方法時,我得到以下異常,它不是擊中web服務。
Infact我正在使用XStream以及客戶端/ WebService。
代碼是這樣的Web服務框架:
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;
}
我的客戶端代碼是這樣的:
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是一個簡單的POJO是同時存在於客戶端和web服務側。
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;
}
}
最後也是最重要的WSDL是在這裏:

而堆棧跟蹤爲例外,我必須修改:
我不是很肯定,如果它擊中Web服務層。

它看起來像XStream desirialization更多的一些問題。即使SOVO在classpath中爲什麼會發生?我錯過了什麼嗎?
當我嘗試發送XXXXX爲字符串,它告訴:之前開始標記,而不是X
只有空白內容允許(位置:START_DOCUMENT看到X ... @ 1:1)
當我嘗試發送「一些價值」,它說:之前開始標記和不發
只有空白內容允許(位置:START_DOCUMENT看到小號... @ 1:1)
我不確定有什麼問題。
你可以發佈WSDL和一些代碼嗎? – Thomas
正如@Thomas所說,WSDL將會很棒......客戶端代碼以及 – home
我建議通過使用Web服務資源管理器測試它,以確保您的Web服務正常工作(運行 - >底部項目..您使用的是Eclipse我會承擔)。 – bdares
