我正在尝试设置加密消息，如guide/example
所示我已经完成了jndi属性的所有步骤。当我去构建在这个站点给出的源代码（包括导入）时，我得到以下异常。
源代码：

我收到的错误消息如下：

由于这些错误提到第86行，即：
Context context = new InitialContext(properties);
在我看来，属性文件有问题，目前是以下内容（摘自教程网站，略有修改）：
java.naming.factory.initial = org.apache.qpid.jndi.PropertiesFileInitialContextFactory
# connection factories. This is where end-to-end encryption is configured on the client.
# connectionfactory.[jndiname] = [ConnectionURL]
connectionfactory.producerConnectionFactory = amqp://guest:guest@?brokerlist='tcp://localhost:5672?encryption_remote_trust_store='$certificates%255c/clientcerts''
connectionfactory.consumer1ConnectionFactory = amqp://<username>:<password>@?brokerlist='tcp://localhost:5672?encryption_key_store='path/to/client_1.jks'&encryption_key_store_password='<keystore_password>''
connectionfactory.consumer2ConnectionFactory = amqp://<username>:<password>@?brokerlist='tcp://localhost:5672?encryption_key_store='path/to/client_2.jks'&encryption_key_store_password='<keystore_password>''
# Rest of JNDI configuration. For example
# destination.[jniName] = [Address Format]
queue.myTestQueue = testQueue
所以，我想我的真正问题是，如何正确设置属性文件以便我可以运行这个示例？
