[英]Spring web service client XwsSecurityInterceptor afterCompletion exception
我已经实现了一个Spring Web 服务服务器和客户端，配置如下。
我选择了使用simplePasswordSecurity机制，并且双方都适合处理这个问题。 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将响应发回。
在我的终端日志中，我可以看到客户端收到了响应，但我突然收到了这个异常：
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)
....
任何想法为什么我得到这个例外？

您的类路径中很可能有不兼容的 JAR。
抽象方法错误
AbstractMethodError是一个运行时错误，当应该存在的方法实际上不存在时，JVM 会抛出该错误。
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，编译器不会警告您。
假设我有 A-1.0.jar，它包含 A 类，它有一个方法doStuffV1() 。
然后是 A-2.0.jar，它包含对 A 类的更新，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，B 类扩展了 A。
在您的项目中，如果您仅导入 B-2.0.jar，并且您使用 B 类并调用doStuffV2 ，则编译器不会抱怨：您正在使用一个正在运行的类。
但是，如果在运行时，您将类路径 A-1.0.jar 和 B-2.0.jar 放入，当您的代码执行时，您将得到AbstractMethodError ：编译 B-2.0.jar 时存在的内容，在运行时不存在。 这是一次崩溃。
应用于 Spring WS Jars 2.0.0 到 2.2.0
在 Spring WS 中，如果您查看您正在引用的 Spring WS 2.0.0 Javadoc，您可以在这里看到（ http://docs.spring.io/spring-ws/sites/2.0/apidocs/index.html ） 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，只是具有不同的签名。 对于 Java 编译器和运行时，这不是相同的方法：
public void afterCompletion(MessageContext messageContext, Exception ex) 抛出 WebServiceClientException
来自您的堆栈跟踪的信息
您的堆栈跟踪表明来自 WSTemplate 类的运行时尝试调用更高版本（请参阅第一行）。
java.lang.AbstractMethodError: ...XwsSecurityInterceptor.afterCompletion(Lorg/springframework/ws/context/MessageContext;Ljava/lang/Exception;)V at org...WebServiceTemplate.triggerAfterCompletion(WebServiceTemplate.java:806)
这向我表明
那是不兼容的。 您应该保持两个版本同步。
编辑：用你的 POM，这似乎得到证实。
使用JPA的Spring事务在AfterCompletion阶段抛出Exception
