使用 Axis2 wsdl2java 生成的异常类不会扩展异常

Question

我正在尝试使用wsdl2java生成一个客户端。wsdl如下：

</wsdl:definitions>

我发现的问题是，如果要解压缩类（使用选项-u），类AdminServiceException不会扩展java.lang.Exception，因此代码不会编译，因为它不能抛出该类。所以情况是这样的：

如果我打包类（没有选项-u），则类定义如下：

    public class AdminServiceException extends java.lang.Exception{....}

但是如果我使用选项-u，则类生成如下：

    public  class AdminServiceException
    implements org.apache.axis2.databinding.ADBBean{....}

这是不正确的，因为它不能被抛出。有什么想法吗？

我只是修改了WSDL使其更加简单。如下所示：

我使用wsdl2java创建了如下代码：

/opt/eco/ecoprd/axis2-1.6.1/bin >> ./wsdl2java.sh  -u -uri test2.wsdl -or
 Using AXIS2_HOME: /opt/eco/ecoprd/axis2-1.6.1
 Using JAVA_HOME:  /usr/local/jdk1.6.0_16
Retrieving document at 'test2.wsdl'.

但当我试图编译代码时：

/opt/eco/ecoprd/axis2-1.6.1/bin >> javac -cp $CLASSPATH  src/com/rsa/csd/ws/admin/*.java
src/com/rsa/csd/ws/admin/Fault.java:95: cannot find symbol

我尝试使用Eclipse IDE用您的第二个wsdl生成客户端。它生成并编译得很好。这意味着wsdl很好用。生成AdminServiceException.java

public class AdminServiceException extends java.lang.Exception{
    private static final long serialVersionUID = 1333311238212L;
    private com.rsa.csd.ws.admin.UserAdminServiceServiceStub.Fault faultMessage;

        public AdminServiceException() {
            super("AdminServiceException");
        }
        public AdminServiceException(java.lang.String s) {
           super(s);
        }
        public AdminServiceException(java.lang.String s, java.lang.Throwable ex) {
          super(s, ex);
        }
        public AdminServiceException(java.lang.Throwable cause) {
            super(cause);
        }

    public void setFaultMessage(com.rsa.csd.ws.admin.UserAdminServiceServiceStub.Fault msg){
       faultMessage = msg;
    }
    public com.rsa.csd.ws.admin.UserAdminServiceServiceStub.Fault getFaultMessage(){
       return faultMessage;
    }
}

对于命令行使用：/wsdl2java.sh-g ssi-uri test2.wsdl您不必提及-u，它将为实现您所使用的绑定的数据绑定器生成单独的类。

Answer 2

wsdl2java应该已经为服务类生成了一个骨架类和/或接口。检查骨架以查看相关服务函数是如何声明的。您可能会发现，它们被声明为抛出类似AdminServiceExceptionException的东西。出于某种原因，Axis2基于WSDL中错误的定义创建了一个类，然后创建了另一个扩展Exception的类，作为第一个类的容器。

Answer 3

如果您使用JAXB数据绑定（JAXBRI），您必须确保以下元素中的wsdl:message名称（AdminServiceException）：

<wsdl:message name="AdminServiceException">
        <wsdl:part element="impl:fault" name="fault"/>
</wsdl:message> 

与元素名称不同（impl:fault）。在你的情况下，它们实际上是不同的。

否则，您将得到"AdminServiceException未扩展java.lang.Exception"错误。
