jaxws的web service的自定义fault.

在jaxws中自定义fault比较绕弯，以下是自定义一个fault的过程。

1 建立web service以及 web method.

@WebService
public interface PersonService {

@WebMethod
public Person getPersonById(String id) throws MyException;

}

2 MyException.里面一定要有一个faultInfo的object.

@WebFault(name = "MyException")
public class MyException extends Exception implements Serializable {

private static final long serialVersionUID = 1L;

private MyFault faultInfo;

public MyException(String s, MyFault faultInfo) {
super(s);
this.faultInfo = faultInfo;
}

public MyFault getFaultInfo() {
return faultInfo;
}

public void setFaultInfo(MyFault faultInfo) {
this.faultInfo = faultInfo;
}
}

3 定义MyFault.

public class MyFault {

private String errMsg;
private int errCode;

public String getErrMsg() {
return errMsg;
}

public void setErrMsg(String errMsg) {
this.errMsg = errMsg;
}

public int getErrCode() {
return errCode;
}

public void setErrCode(int errCode) {
this.errCode = errCode;
}

}

4 发布web service. 查看wsdl，可以看到以下内容。
- <message name="MyException"> 
            <part element="tns:MyException" name="fault" />  

 </message>

 

- <portType name="PersonService">
- <operation name="getPersonById">
  <input message="tns:getPersonById" />
  <output message="tns:getPersonByIdResponse" />
  <fault message="tns:MyException" name="MyException" />
  </operation>
  </portType>

 

<xs:element nillable="true" name="MyException" type="tns:myFault" />

- <xs:complexType name="myFault">

- <xs:sequence>

  <xs:element name="errCode" type="xs:int" />

  <xs:element name="errMsg" type="xs:string" minOccurs="0" />

  </xs:sequence>

</xs:complexType>

 

5 在client验证。

try {
      p = ps.getPersonById("exception");
     } catch (MyException me) {

      MyFault myFault = me.getFaultInfo();

      log.log(Level.INFO, "Error ErrCode = "
        + myFault.getErrCode());
      log.log(Level.INFO, "Fault ErrMsg = "
        + myFault.getErrMsg());
}

 

绕了好大一圈，擦汗。

貌似jaxws2.1可以直接map java exception到fault. 有时间可以试一试。
