非法字符實體：擴展字符（代碼0xe

Question

我使用CXF連接SOAP的Web服務有些時候，同時要求我得到非法字符實體服務器：擴展字符代碼0xe例外

我發現。 ，由於在XML中非法的字符，該異常發生。此外，我找到了解決這個

XMLOutputFactory f = new WstxOutputFactory(); 
    f.setProperty(WstxOutputProperties.P_OUTPUT_INVALID_CHAR_HANDLER, 
    new InvalidCharHandler.ReplacingHandler(' ')); 
    XMLStreamWriter sw = f.createXMLStreamWriter(...); 

但我不知道如何在CXF應用它。有人能告訴我在哪裏，我必須使用CXF此代碼。謝謝建議。

Answer 1

您可以在服務器上使用傳入攔截器或在客戶端上使用傳出攔截器，並在解組發生之前清理xml。

傳入階段

------------------------------------------------------------------------------ 
|Phase     | Functions          | 
------------------------------------------------------------------------------ 
|RECEIVE     | Transport level processing      | 
|(PRE/USER/POST)_STREAM | Stream level processing/transformations   | 
|READ |     | This is where header reading typically occurs | 
|(PRE/USER/POST)_PROTOCOL | Protocol processing, such as JAX-WS SOAP handlers| 
|UNMARSHAL    | Unmarshalling of the request      | 
|(PRE/USER/POST)_LOGICAL | Processing of the umarshalled request   | 
|PRE_INVOKE    | Pre invocation actions       | 
|INVOKE     | Invocation of the service      | 
|POST_INVOKE    | Invocation of the outgoing chain if there is one | 
------------------------------------------------------------------------------ 

引出相位

--------------------------------------------------------------------------------------- 
|Phase     | Functions             | 
--------------------------------------------------------------------------------------- 
|SETUP     | Any set up for the following phases      | 
|(PRE/USER/POST)_LOGICAL | Processing of objects about to marshalled     | 
|PREPARE_SEND    | Opening of the connection         | 
|PRE_STREAM    |               | 
|PRE_PROTOCOL    | Misc protocol actions          | 
|WRITE     | Writing of the protocol message, such as the SOAP Envelope| 
|MARSHAL     | Marshalling of the objects        | 
|(USER/POST)_PROTOCOL  | Processing of the protocol message      | 
|(USER/POST)_STREAM  | Processing of the byte level message      | 
|SEND      |               | 
--------------------------------------------------------------------------------------- 

請記住，你將不得不解編（進入）之前或編組（離開）之後做到這一點。

Here你可以找到所有的細節，以及使用inteceptors的必要示例。

一些調查研究後，我發現這些：

1. Solution with spring
2. Solution without spring

複製，並從第二個鏈接粘貼（第一個是SO回答）

package tmp; 

public class MyWstxOutputFatory extends WstxOutputFactory { 
    public MyWstxOutputFatory() { 
     setProperty(com.ctc.wstx.api.WstxOutputProperties.P_OUTPUT_INVALID_CHAR_HANDLER, 
        new 
com.ctc.wstx.api.InvalidCharHandler.ReplacingHandler(' ')); 
    } 
} 

，並用它在你的JAXWS配置

<bean id="outStaxFactory" class="tmp.MyWstxOutputFatory"/> 

    <!-- jaxws:client or server --> 
     ... 
     <jaxws:properties> 
      <entry key="javax.xml.stream.XMLOutputFactory"> 
       <ref bean="outStaxFactory"/> 
      </entry> 
     </jaxws:properties> 
     ...
