非法注释例外：两个类具有相同的 XML 类型名称

java jaxb jboss jbossws

2022-09-01 04:07:10

我正在JBoss 5和Java 1.6下开发Web服务。什么可能导致此异常？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。

答案 1

我找到了问题的原因。

出现此问题的原因是 JAX-WS 为每个方法生成一个类，并且类名是通过连接 + 来构造的。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。methodName"Response"

例：

@Stateless
@WebService()
public class AccountWS {

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

JAX-WS 将为 Web 方法生成一个与响应对象同名的新类。CreateAccountResponsecreateAccount

溶液：

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 2

您有两个 XML 模式元素，它们具有相同的名称（）和相同的命名空间（），对应于 Java 类型和。由于第二个是由WebMethod注释生成的“自动魔术”，因此更改消息元素的XMLType注释将更容易。createAccountResponsehttp://kona.webservice.sif.unidata.com/com.unidata.sif.kona.account.message.CreateAccountResponsecom.unidata.sif.webservice.kona.jaxws.CreateAccountResponse

要解决此问题，您应该更改其中一个命名空间，或者定义两个单独的命名空间（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）。name

即：

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

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

2. 更改消息元素（包）处的命名空间com.unidata.sif.kona.account.message)

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