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

时间：2010-11-23 09:09:13

标签： java jboss jaxb jbossws

我正在JBoss 5和Java 1.6下开发Web服务。什么可能导致这个例外？以下是我简化的网络服务代码。

@Stateless
@WebService()
public class AccountWS {

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

以下是完整的堆栈跟踪。

答案 0 :(得分：82)

我找到了问题的原因。

出现此问题是因为JAX-WS为每个方法生成一个类，并且通过连接methodName + "Response"来构造类名。在我的例子中，JAX-WS新生成的类将与我的响应对象具有相同的名称。

示例：

@Stateless
@WebService()
public class AccountWS {

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

JAX-WS将为Web方法CreateAccountResponse生成一个新类createAccount，它与响应对象具有相同的名称。

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。

答案 1 :(得分：13)

您有两个具有相同名称（createAccountResponse）和相同名称空间（http://kona.webservice.sif.unidata.com/）的XML架构元素，这些元素对应于Java类型com.unidata.sif.kona.account.message.CreateAccountResponse和com.unidata.sif.webservice.kona.jaxws.CreateAccountResponse。由于第二个是由WebMethod注释生成的“automagicaly”，因此更改消息元素的XMLType anotation会更容易。

要解决此问题，您应该为其中一个更改name，或者定义两个独立的命名空间（一个用于消息元素，另一个用于WS请求和响应组件）。我推荐最后一种方法（两个独立的命名空间）。

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. 更改邮件元素的命名空间（包com.unidata.sif.kona.account.message）

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

答案 2 :(得分：4)

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的方法名为wsgen和wsimport生成类;但现在消息元素类与JAX_WS内部生成的类不同。

我不想触及wsgen生成的类（消息元素类）。

答案 3 :(得分：3)

我遇到了同样的错误，但我无法使用@XmlType注释来自类（来自库） 所以另一种解决方案是在

中提供com.unidata.sif.kona.account.message/package-info.java以下代码 
@javax.xml.bind.annotation.XmlSchema(namespace = "http://kona.webservice.sif.unidata.com/")
package com.sopra.banking.processengine.servicecontract.v1_1.dto;
