我正在尝试从gwt服务器发送编组jaxb数据，并在jboss运行的servlet接收中读取它。
发送部分的代码:
url = new URL(MessageFormat.format(urlStr,ip));
conn = url.openConnection();
conn.setReadTimeout(ApplicationSettings.instance.m_nUrlReadTimeout_ms);
conn.setConnectTimeout(ApplicationSettings.instance.m_nUrlConnectTimeout_ms);
conn.setDoOutput(true);
conn.setDoInput(true);
OutputStreamWriter outStream = new OutputStreamWriter( conn.getOutputStream());
Marshaller tmarshaller;
JAXBContext tJAXB= JAXBContext.newInstance(path.to.application.jaxb.componentCurrentKPIs.ComponentCurrentKPIs.class);
tmarshaller = tJAXB.createMarshaller();
tmarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
tmarshaller.marshal(new JAXBElement<ComponentCurrentKPIs>(new QName("componentCurrentKPIs"), ComponentCurrentKPIs.class, currentTableChanges), outStream);
outStream.flush();
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
String line = reader.readLine();
reader.close();
outStream.close();
在eclipse调试中，海报输出流如下所示
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<componentCurrentKPIs command="http://{0}:8080/monserver/SetCurrentKpis/?user=xxxx&password=xxxx">
<CurrentKPI value="interface0:interface1" name="Interface"/>
<CurrentKPI value="false:false" name="Enable"/>
<CurrentKPI value="interface:interface1" name="PassThroughPort"/>
</componentCurrentKPIs>
这是接收部分
public void processRequest(HttpServletRequest pRequest, HttpServletResponse pResponse)throws IOException
{
//To avoid new request while a request is processed
synchronized (lock)
{
try
{
JAXBContext tJAXB = JAXBContext.newInstance("path.to.class.supervisor.jaxb.componentCurrentKPIs");
tJAXB = JAXBContext.newInstance(ComponentCurrentKPIs.class);
Unmarshaller tUnmarshaller = tJAXB.createUnmarshaller();
JAXBElement model = null;
BufferedReader rd = new BufferedReader(new InputStreamReader(pRequest.getInputStream()));
model = (JAXBElement)tUnmarshaller.unmarshal(rd);
ComponentCurrentKPIs currentKpis = (ComponentCurrentKPIs) model.getValue();
for(CurrentKPI kpi : currentKpis.getCurrentKPI())
{
Logger.getLogger(SetCurrentKpis.class).debug("in Set Current Kpis !" + kpi.getName() + " = " + kpi.getValue());
}
} catch (Exception e)
{
Logger.getLogger(SetCurrentKpis.class).error("Exception !" ,e);
}
PrintWriter out = pResponse.getWriter();
out.println("aaaaaaaaaaaaaaaaa");
}
}
}
和我得到异常在servlet(接收部分)

我发现了问题:
-
我需要添加内容类型定义:
。setRequestProperty("内容类型","text/html");
-
我需要@XmlRootElement在xsd生成的代码。我仍然不知道如何生成它。但似乎有很多关于这个
-
我有一个类型转换错误，所以为了学习非编组类型，我打印了非编组对象类
Object 0 = tUnmarshaller.unmarshal(rd);打印o.getClass ();
