Question

我正在使用JBoss 6 AS并试图通过AOP将拦截器添加到部署应用程序的某些包中的类中。这是场景：

我有一个app.jar，其中包含我想要添加建议的类。这个JAR还有一些EJB（ejb-jar.xml，jboss.xml）。

我在JBoss拦截器上创建了这样的：

package util;
import org.jboss.aop.joinpoint.Invocation;
import org.jboss.aop.joinpoint.MethodInvocation;
public class MyInterceptor implements org.jboss.aop.advice.Interceptor {
    @Override
    public Object invoke(Invocation invocation) throws Throwable {
        long startTime = System.currentTimeMillis();
        try {
            return invocation.invokeNext();
        } finally {
            long endTime = System.currentTimeMillis() - startTime;
            System.out.println("MyInterceptor : " + endTime);
            if (invocation instanceof MethodInvocation) {
                MethodInvocation mi = (MethodInvocation) invocation;
                String clazz = "";
                String method = "";
                try {
                    clazz = mi.getTargetObject().getClass().toString();
                    method = mi.getMethod().getName();
                } catch (Throwable e) {
                    System.out.println("Error when trying to get target info");
                }
                System.out.println("MyInterceptor : " + endTime);
            }
        }
    }

    @Override
    public String getName() {
        return "MyInterceptor";
    }
}

我创建了一个jboss-aop.xml文件，其中包含：

<?xml version="1.0" encoding="UTF-8"?>
<aop xmlns="urn:jboss:aop-beans:1.0">
    <interceptor name="MyInterceptor"  class="util.MyInterceptor"/>
    <bind pointcut="execution(* my.app.*->*(..))">
        <interceptor-ref name="MyInterceptor"/>
    </bind>
</aop>

我已设置enableLoadTimeWeaving（bootstrap / aop.xml）
我pluggable-instrumentor.jar在正确的地方（JBOSS / bin）
我使用选项-javaagent:pluggable-instrumentor.jar
我已经创建了一个JAR文件interceptor.jar，我放了MyInterceptor.class并在其META-INF中放置了jboss-aop.xml文件

现在，问题是，当我运行我的应用程序并且来自my.app包中的任何类的某些方法被调用时，拦截器似乎拦截了调用，但它引发了一个讨厌的{{1} }。这是我的错误堆栈的一部分：

StackOverflowError

基本上会发生这样的情况：在java.lang.StackOverflowError at org.jboss.resteasy.core.SynchronousDispatcher.unwrapException(SynchronousDispatcher.java:345) [:6.1.0.Final] at org.jboss.resteasy.core.SynchronousDispatcher.handleApplicationException(SynchronousDispatcher.java:321) [:6.1.0.Final] at org.jboss.resteasy.core.SynchronousDispatcher.handleException(SynchronousDispatcher.java:214) [:6.1.0.Final] at org.jboss.resteasy.core.SynchronousDispatcher.handleInvokerException(SynchronousDispatcher.java:190) [:6.1.0.Final] at org.jboss.resteasy.core.SynchronousDispatcher.getResponse(SynchronousDispatcher.java:534) [:6.1.0.Final] at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:496) [:6.1.0.Final] at org.jboss.resteasy.core.SynchronousDispatcher.invokePropagateNotFound(SynchronousDispatcher.java:155) [:6.1.0.Final] at org.jboss.resteasy.plugins.server.servlet.ServletContainerDispatcher.service(ServletContainerDispatcher.java:212) [:6.1.0.Final] at org.jboss.resteasy.plugins.server.servlet.FilterDispatcher.doFilter(FilterDispatcher.java:59) [:6.1.0.Final] at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:274) [:6.1.0.Final] at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:242) [:6.1.0.Final] at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:275) [:6.1.0.Final] at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:161) [:6.1.0.Final] at org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:181) [:6.1.0.Final] at org.jboss.modcluster.catalina.CatalinaContext$RequestListenerValve.event(CatalinaContext.java:285) [:1.1.0.Final] at org.jboss.modcluster.catalina.CatalinaContext$RequestListenerValve.invoke(CatalinaContext.java:261) [:1.1.0.Final] at org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:88) [:6.1.0.Final] at org.jboss.web.tomcat.security.SecurityContextEstablishmentValve.invoke(SecurityContextEstablishmentValve.java:100) [:6.1.0.Final] at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:159) [:6.1.0.Final] at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) [:6.1.0.Final] at org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:158) [:6.1.0.Final] at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) [:6.1.0.Final] at org.jboss.web.tomcat.service.request.ActiveRequestResponseCacheValve.invoke(ActiveRequestResponseCacheValve.java:53) [:6.1.0.Final] at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:362) [:6.1.0.Final] at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:877) [:6.1.0.Final] at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:654) [:6.1.0.Final] at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:951) [:6.1.0.Final] at java.lang.Thread.run(Thread.java:745) [:1.7.0_79] Caused by: java.lang.StackOverflowError at my.app.JoinPoint_invoke_N_5164114663869737738_3.invokeJoinpoint(JoinPoint_invoke_N_5164114663869737738_3.java) [:] at my.app.MyInterceptor$MyInterceptorAdvisor.invoke_N_5164114663869737738(MyInterceptor$MyInterceptorAdvisor.java) [:] at my.app.MyInterceptor.invoke(MyInterceptor.java) [:] at my.app.JoinPoint_invoke_N_5164114663869737738_3.invokeNext(JoinPoint_invoke_N_5164114663869737738_3.java) [:] at my.app.JoinPoint_invoke_N_5164114663869737738_3.invokeJoinpoint(JoinPoint_invoke_N_5164114663869737738_3.java) [:] at my.app.MyInterceptor$MyInterceptorAdvisor.invoke_N_5164114663869737738(MyInterceptor$MyInterceptorAdvisor.java) [:] at my.app.MyInterceptor.invoke(MyInterceptor.java) [:]被提升之前，这四行被抛出：

如果有人有类似的问题，任何帮助都会被指定！

Answer 1

我发现了问题...我把拦截器放在同一个包my.app而不是util ...所以最终它会无休止地调用它直到堆栈已满。所以...我的坏

带有AOP的JBoss 6 AS抛出StackOverflowError
