非法字符实体:扩展字符(代码0xe

Question

我正在使用CXF来连接SOAP Web服务。有时在请求服务器时，我收到非法字符实体：扩展字符代码0xe异常。

我发现由于 Xml 中的非法字符，会发生此异常。我也找到了解决方案。

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

但是我不知道如何在CXF中应用它。有人可以告诉我必须在 CXF 中在哪里使用此代码。谢谢建议。

您可以在服务器上使用传入拦截器，也可以在客户端上使用传出拦截器，并在解组发生之前清理 xml。

请记住，您必须在取消编组（传入）或编组（传出）之后执行此操作。

从第二个链接复制并粘贴（第一个是SO答案）

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(' '));
    }
}

并在您的 JAXWS 配置中使用它

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