更新已弃用的 WAS-MQ 代码

Question

我正在将基于 WAS 6.1 的应用程序迁移到 WAS 7.0 我发现下面两条语句

com.ibm.mq.MQEnvironment.securityExit = null; // 1

和

MQQueueConnectionFactory factory = new MQQueueConnectionFactory();
factory.setTransportType(JMSC.MQJMS_TP_CLIENT_MQ_TCPIP); // 2

1. 在线#1 securityExit 是 deprecated 文档说：

   The security exit used when connecting to a queue manager. It allows you to customise the security flows that occur when an attempt is made to connect to a queue manager. If you want to provide your own security exit, define a class that implements the MQSecurityExit interface and assign securityExit to an instance of that class. If you set this field to null no security exit is called.

   据我了解，com.ibm.mq.MQSecurityExit 接口需要实现。 将 securityExit 分配给该类的实例是什么意思？

2. 在线#2 JMSC 是 deprecated。医生说：

   This parameter can be passed to MQConnectionFactory.setTransportType(int) to indicate that the application should connect to the queue manager in client TCP/IP mode.

   对于文档说的界面也是：

   Use the constants defined in the classes in the com.ibm.mq.constants package instead

   com.ibm.mq.constants 的文档没有多大帮助。

感谢您在替换已弃用的语句方面的任何帮助。

这意味着您需要创建 MQSecurityExit 类的实现实例并设置安全出口属性。像这样的

   // in MySecurityExit.java
   class MySecurityExit implements MQSecurityExit 
   {
       // you must provide an implementation of the securityExit method
       public byte[] securityExit(MQChannelExit       channelExitParms,
                                  MQChannelDefinition channelDefinition,
                                  byte[]              agentBuffer)
       {
           // your exit code goes here...
       }
   }

   // in your main program...
   MQEnvironment.securityExit = new MySecurityExit();
   ...    // other initialisation
   MQQueueManager qMgr        = new MQQueueManager("");

setTransportType 方法确定您的应用程序如何连接到 WMQ 队列管理器，应用程序和队列管理器是否通过共享内存或套接字或 HTTP 等进行通信。此方法的可能值定义为 here
