IllegalAnnotationException：两个类具有相同的XML类型名称

Question

我正在JBoss 5和Java 1.6下开发Web服务。什么可能导致这种异常？以下是我简化的Web服务代码。

@Stateless 
@WebService() 
public class AccountWS { 

@WebMethod() 
public CreateAccountResponse createAccount(@WebParam(name = "request") CreateAccountRequest request) { 
    return null; 
} 

下面是完整的堆栈跟踪。

Answer 1

我发现我的问题的原因。

发生此问题的原因是JAX-WS为每种方法生成一个类，并通过级联methodName + "Response"构造类名。在我的情况下，JAX-WS新生成的类将与我的响应对象具有相同的名称。

实施例：

@Stateless 
@WebService() 
public class AccountWS { 

    @WebMethod() 
    public CreateAccountResponse createAccount(@WebParam(name = "request") CreateAccountRequest request) { 
     return null; 
    } 
} 

JAX-WS将产生一个新的类CreateAccountResponse对于具有相同的名称作为响应对象Web方法createAccount。

解决方案：

确保响应对象和方法的名称不匹配。同样的事情也适用于方法参数。

Answer 2

你必须使用相同的名称（createAccountResponse）和对应的Java类型com.unidata.sif.kona.account.message.CreateAccountResponse和com.unidata.sif.webservice.kona.jaxws.CreateAccountResponse同一个命名空间（http://kona.webservice.sif.unidata.com/）两个XML架构元素。第二个是由WebMethod注释生成的“automagicaly”，它将更容易更改消息元素的XMLType注释。

要解决这个问题，您应该为其中的一个更改name，或者定义两个分开的名称空间（一个用于消息元素，另一个用于WS请求和响应组件）。我建议最后一种方法（两个分开的命名空间）。

即：

1.更改消息元素com.unidata.sif.kona.account.message.CreateAccountResponse的名称。

@XMLType(name="CreateAccountResponseMsg", namespace="http://kona.webservice.sif.unidata.com") 

2.改变在消息元素的命名空间（包com.unidata.sif.kona.account.message）

@XMLType(name="CreateAccountResponse", namespace="http://kona.webservice.sif.unidata.com/message") 

Answer 3

另一种解决方案是使用@WebMethod(operationName="differentFromMethodName")。这甚至会更改客户端上的接口方法名称。 JAX-WS仍然使用SEI的方法名称为wsgen和wsimport生成类;但现在消息元素类与JAX_WS内部生成的不同。

我不想触摸wsgen生成的类（消息元素类）。

Answer 4

我得到了同样的错误，但我不能ajust使用@XmlType注释（从库中推出） 那么另一种解决方案是提供一个com.unidata.sif.kona.account.message/package-info.java与下面的代码内

@javax.xml.bind.annotation.XmlSchema(namespace = "http://kona.webservice.sif.unidata.com/") 
package com.sopra.banking.processengine.servicecontract.v1_1.dto;
