Java 更改（或设置）编码web服务

我有一个使用JAX-WSAPI（SOAPWeb服务）的web服务

如何将其编码更改为“UTF-8”（非英语字符）？ 我找到了类似“@products（“text/html；charset=UTF-8”）”的东西，但它是用于JAX-RS（RESTfulWeb服务）的，我需要用于JAX-WS的东西。

谢谢。

首先，您需要尽早获得SOAP消息。最好的开始位置是（与更常见的处理程序类型相反，）

LogicalHandler

在

SOAPHandler

之前拦截SOAP负载，因此它是执行此操作的理想位置

在这个处理程序中，在编码成为问题之前，您就可以自由地对消息进行任何处理。您的代码应该如下所示

public class YourHandler implements LogicalHandler{

    public boolean handleMessage(LogicalMessageContext context) {
    boolean inboundProperty= (boolean)context.get(MessageContext.MESSAGE_INBOUND_PROPERTY);

         if (inboundProperty) {
              LogicalMessage lm = context.getMessage();
              Source payload = lm.getPayload();
              Source recodedPayload = modifyEncoding(payload); //This is where you change the encoding. We'll talk more about this
              lm.setPayload(recodedPayload) //remember to stuff the payload back in there, otherwise your change will not be registered
         } 

    return true;
    }   

}

现在你有消息了。如何处理编码的变化可能很棘手，但完全取决于您

您可以选择在整个消息上设置编码，或者导航（使用）到您感兴趣的字段并进行处理。即使是这两种选择，也有几种方法可以同时实现。我将采用惰性路线：在整个有效负载上设置编码：

     private Source modifyEncoding(Source payload){
         StringWriter sw = new StringWriter();
         StreamSource newSource = null;     
             try {
                  TransformerFactory transformerFactory = TransformerFactory.newInstance();
                  Transformer transformer = transformerFactory.newTransformer();
                  transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8"); //this determines the outcome of the transformation
                  StreamResult output =  new StreamResult(sw);
                  transformer.transform(source, output);
                  StringReader sReader = new StringReader(sw.toString());
                  newSource = new StreamSource(sReader);//Stuff the re-encoded xml back in a Source
             } catch(Exception e){
               ex.printStackTrace();
             }
         return newSource;
     }

在

LogicalHandler

之后，您现在拥有了

SOAPHandler

。在这里，设置编码更简单，但其行为取决于实现。您的

SOAPHandler

可以如下所示：

   public class YourSOAPHandler implements SOAPHandler{

        public boolean handleMessage(SOAPMessageContext msgCtxt){
        boolean inbound = (boolean)msgCtxt.get(MessageContext.MESSAGE_INBOUND_PROPERTY);

           if (inbound){
             SOAPMessage msg = msgCtxt.getMessage();
             msg.setProperty(javax.xml.soap.SOAPMessage.CHARACTER_SET_ENCODING,"UTF-8");

             msgCtxt.Message(msg); //always put the message back where you found it.
           } 
       }      
     return true;
   }

   public class YourSOAPHandler implements SOAPHandler{

        public boolean handleMessage(SOAPMessageContext msgCtxt){
        boolean inbound = (boolean)msgCtxt.get(MessageContext.MESSAGE_INBOUND_PROPERTY);

           if (inbound){
             SOAPMessage msg = msgCtxt.getMessage();
             msg.setProperty(javax.xml.soap.SOAPMessage.CHARACTER_SET_ENCODING,"UTF-8");

             msgCtxt.Message(msg); //always put the message back where you found it.
           } 
       }      
     return true;
   }
