我正在使用 CXF 连接 SOAP Web 服务。有时在请求服务器时我得到非法字符实体：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(...);

但我不知道如何在 CXF 中应用它。有人可以告诉我我必须在 CXF 中在哪里使用此代码。谢谢您的建议。

您可以在服务器上使用传入拦截器或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，您必须在解组（传入）之前或编组（传出）之后执行此操作。

  2. 无弹簧解决方案

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>
       ...
