java - Spring Web 服务客户端 XwsSecurityInterceptor afterCompletion 异常

Question

我已经实现了一个 Spring Web Service Server 和 Client，配置如下。

我已选择使用 simplePasswordSecurity 机制，双方 都适合处理此问题。到目前为止，我可以将我的请求从客户端发送到服务器，服务器将处理请求并发回响应。

在我的终端日志中，我可以看到客户端收到了响应，但是我不知从哪里得到了这个异常:

java.lang.AbstractMethodError: org.springframework.ws.soap.security.xwss.XwsSecurityInterceptor.afterCompletion(Lorg/springframework/ws/context/MessageContext;Ljava/lang/Exception;)V
at org.springframework.ws.client.core.WebServiceTemplate.triggerAfterCompletion(WebServiceTemplate.java:806)
at org.springframework.ws.client.core.WebServiceTemplate.doSendAndReceive(WebServiceTemplate.java:615)
at org.springframework.ws.client.core.WebServiceTemplate.sendAndReceive(WebServiceTemplate.java:555)

....

我得到这个异常的任何想法？

Answer 1

您的类路径中很可能有不兼容的 JAR。

抽象方法错误

AbstractMethodError 是 JVM 在应该存在的方法实际上不存在时抛出的运行时错误。

这不应该发生在您自己的代码中:编译器会阻止您调用不存在的方法。

但是，当使用外部 JAR(依赖于其他外部 JAR)时，编译器无法警告您。

假设我有 A-1.0.jar，它包含类 A，它有一个方法 doStuffV1()。
然后是 A-2.0.jar，其中包含对类 A 的更新，它添加了另一个方法 doStuffV2()。最后，假设我有 B-2.0.jar，它是用 A-2.0.jar 编译的，具有扩展 A 的类 B。

在您的项目中，如果您只导入 B-2.0.jar，并且您使用类 B 并调用 doStuffV2，编译器不会提示:您正在使用一个正在工作的类。

但是，如果在运行时，您将 A-1.0.jar 和 B-2.0.jar 放入类路径中，那么当您的代码执行时，您将得到 AbstractMethodError :B-2.0 时存在的内容。 jar 已编译，在运行时不存在。这是一次崩溃。

适用于 Spring WS Jars 2.0.0 到 2.2.0

在 Spring WS 中，如果您查看正在引用的 Spring WS 2.0.0 Javadoc，您可以在此处 (http://docs.spring.io/spring-ws/sites/2.0/apidocs/index.html) 看到 afterCompletion 签名:

public void afterCompletion(MessageContext messageContext,Object endpoint,Exception ex)

但是如果您查看 2.2.0 api ( http://docs.spring.io/spring-ws/docs/2.2.0.RELEASE/api/ )，确实存在相同的方法，只是签名不同。对于 Java 编译器和运行时，这不是同一个方法:

public void afterCompletion(MessageContext messageContext,Exception ex)throws WebServiceClientException

来自堆栈跟踪的信息

您的堆栈跟踪表明运行时从 WSTemplate 类尝试调用更高版本(请参阅第一行)。

java.lang.AbstractMethodError: ...XwsSecurityInterceptor.afterCompletion(Lorg/springframework/ws/context/MessageContext;Ljava/lang/Exception;)Vat org...WebServiceTemplate.triggerAfterCompletion(WebServiceTemplate.java:806)

这对我来说是

1. 你有一个 2.2.0 版本的 Spring-WS-Core (WebServiceTemplate.class)
2. 使用 2.1.0 版本(或介于两者之间的版本)的 Spring WS Security (XwsSecurityInterceptor)。

那是不兼容的。您应该使两个版本保持同步。

编辑:通过您的 POM，这似乎得到了证实。
