Question

我创建了一个自定义调解器。当我在/ repository / components / lib＆＃39;中部署jar时文件夹，它抛出以下异常。请检查下面的代码和例外。

我在component / lib / component / dropins中复制了synapse-core_2.1.2.wso2v2，但这没有帮助。我不认为我需要复制这些库，因为它们是作为WSO2 ESB一部分的核心库。

有人可以帮助我们为什么会抛出这个例外吗？我在developer studio中创建了这个Mediators并创建了jar。它应该没有任何问题地部署。

代码：

public boolean mediate(MessageContext synCtx) { 

    SynapseLog synLog = getLog(synCtx);

    if (synLog.isTraceOrDebugEnabled()) {
        synLog.traceOrDebug("Start : Cache mediator");

        if (synLog.isTraceTraceEnabled()) {
            synLog.traceTrace("Message : " + synCtx.getEnvelope());
        }
    }

    ConfigurationContext cfgCtx =
            ((Axis2MessageContext) synCtx).getAxis2MessageContext().getConfigurationContext();

例外：

只有在您开发了自定义类介体

时，您的自定义jar才会转到repository / components / lib

如果您已经开发了一个真正的中介（具有您可以在中介中使用的特定名称，并且它是序列化器和工厂，并且它'在META-INF / services中输入MediatorFactory＆amp; MediatorSerializer），您必须生成一个带有maven-bundle-plugin的jar转到repository / components / dropins
