Two classes have the same XML type name 排错【转】

今天遇到一个问题，webservice发布的时候报下面的错误:

<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.com}createProcessResponse". 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:

        at xxx.yyy.gwfp.ws.jaxws_asm.CreateProcessResponse

    at com.sun.xml.bind.v2.runtime.IllegalAnnotationsException$Builder.check(IllegalAnnotationsException.java:102)

    at org.apache.cxf.jaxb.JAXBDataBinding.initialize(JAXBDataBinding.java:322)</strong>

代码如下

@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.
