今天遇到一个问题,webservice发布的时候报下面的错误:
Java代码
- <strong>Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 1 counts of IllegalAnnotationExceptions
- Two classes have the same XML type name "http://xxx.yyyy.comcreateProcessResponse". Use @XmlType.name and @XmlType.namespace to assign different names to them.
- this problem is related to the following location:
- at xxx.yyy.gwfp.ws.dto.CreateProcessResponse
- at private xxx.yyy.gwfp.ws.dto.CreateProcessResponse xxx.yyy.gwfp.ws.jaxws_asm.CreateProcessResponse._return
- at xxx.yyy.gwfp.ws.jaxws_asm.CreateProcessResponse
- this problem is related to the following location:

代码如下:
Java代码- @Stateless
- @WebService()
- public class AccountWS
- @WebMethod()
- public CreateProcessResponse createProcess(@WebParam(name = "request") CreateProcessRequest request)
- return null;
起初找不出来原因,后来才发现,由于JAX-WS对webservice里面得每个方法都生成一个类,生成的类名为: methodName
+ "Response",所以就回导致生成的类和原来的类有两个相同的xml type。
知道原因后,除了我们修改方法名外,还有下面的3种解决方法:
- 更换返回值对象的name
@XMLType(name="CreateProcessResponseMsg", namespace="http://xxx.yyy.com")
- 更换返回值对象的namespace
@XMLType(name="CreateProcessResponse", namespace="http://xxx.yyy.com/message")
- 给方法上加上下面的注解
@WebMethod(operationName="differentFromMethodName")
其实在最开始的时候说生成的class的名称是方法名+Response,是不准确的,operationName的默认值就是方法名,其实就是operationName+Response, 这个注解其实会改变生成的类的名称,对接口是没有影响的.
