java - SOAP - 抛出 ServerSOAPFaultException 而不是适当的 @WebFault 异常

Question

我已经从 WSDL 模式生成了 POJO，但错误似乎没有映射到适当的 @Webfault 异常。我收到的是 ServerSOAPFaultException，而不是 AXLError。

生成的异常文件:

package com.cisco.axlapiservice;

import javax.xml.ws.WebFault;


/**
 * This class was generated by Apache CXF 3.1.8
 * 2016-11-13T14:30:37.692+02:00
 * Generated source version: 3.1.8
 */

@WebFault(name = "axlError", targetNamespace = "http://www.cisco.com/AXL/API/11.5")
public class AXLError extends Exception {

    private com.cisco.axl.api._11.AXLError axlError;

    public AXLError() {
        super();
    }

    public AXLError(String message) {
        super(message);
    }

    public AXLError(String message, Throwable cause) {
        super(message, cause);
    }

    public AXLError(String message, com.cisco.axl.api._11.AXLError axlError) {
        super(message);
        this.axlError = axlError;
    }

    public AXLError(String message, com.cisco.axl.api._11.AXLError axlError, Throwable cause) {
        super(message, cause);
        this.axlError = axlError;
    }

    public com.cisco.axl.api._11.AXLError getFaultInfo() {
        return this.axlError;
    }
}

服务器返回的响应:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
   <soapenv:Body>
      <soapenv:Fault>
         <faultcode>soapenv:Client</faultcode>
         <faultstring>Cannot insert or update pattern. A DN exists with the same pattern and partition.</faultstring>
         <detail>
            <axlError>
               <axlcode>4052</axlcode>
               <axlmessage>Cannot insert or update pattern. A DN exists with the same pattern and partition.</axlmessage>
               <request>addLine</request>
            </axlError>
         </detail>
      </soapenv:Fault>
   </soapenv:Body>
</soapenv:Envelope>

抛出以下异常:

您能指出为什么我从未收到 AXLError 吗？

Answer 1

这是 CXF 映射 @WebFault 的标准方法。如果您尝试/捕获接收 WebFault 的 WebService 方法，它将引发 AXLError 异常，其中将包含 com.cisco.axl.api._11.AXLError 中的故障详细信息getFaultInfo()。

我没有看到堆栈跟踪中调用 CXF 类。看来您的客户端正在使用 JDK 中包含的 JAX-WS 的内部实现。也许您忘记将 CXF jar 添加到运行时依赖项中？如果您使用 Maven，您可以使用以下代码片段将它们添加到您的类路径中:
