当应用程序不和IBM MQ的安装程序在一台主机上时，就需要通过IP远程访问IBM MQ队列了，此时可用TCP/IP协议

1. 在创建队列 管理器时，要勾选创建服务器连接通道

2. 创建一个本地队列Q1

3. 右键通道选项，新建服务器连接通道，名称SVRCONN.ONE

4. 代码访问示例，此示例访问windows上的IBM MQ，windows系统设置了用户名和密码

1. import com.ibm.mq.*;

2. import com.ibm.mq.constants.MQConstants;

3.  

4. public class MqDemo {

5.  

6. private MQQueueManager qMgr;

7. private MQQueue sendQueue;

8. private MQQueue receiveQueue;

9. private static int CCSID = 1381;

10. private static String hostname = "192.168.1.133";

11. int port = 1466;

12. static String queueManagerName = "QM_2";

13. static String queueName = "Q1";

14. static String channel = "SVRCONN.ONE";

15. static String userId = "tiger";

16. static String password = "tiger";

17.  

18. public MqDemo() throws MQException {

19.  

20. MQEnvironment.hostname = hostname;

21. MQEnvironment.port = port;

22. MQEnvironment.channel = channel;

23. MQEnvironment.CCSID = CCSID;

24. MQEnvironment.userID = userId; //MQ中拥有权限的用户名

25. MQEnvironment.password = password; //用户名对应的密码

26. qMgr = new MQQueueManager(queueManagerName);//创建队列管理器

27.  

28. }

29.  
30.  

31. public void sendMsg(String msgStr) {

32. int openOptions = MQConstants.MQOO_INPUT_AS_Q_DEF | MQConstants.MQOO_OUTPUT | MQConstants.MQOO_INQUIRE;

33. try {

34. // 建立通道的连接

35. sendQueue = qMgr.accessQueue(queueName, openOptions, null, null, null);

36.  

37. MQMessage msg = new MQMessage();// 要写入队列的消息

38. msg.format = MQConstants.MQFMT_STRING;

39. msg.characterSet = CCSID;

40. msg.encoding = CCSID;

41. msg.writeUTF(msgStr);

42.  

43. MQPutMessageOptions pmo = new MQPutMessageOptions();

44. msg.expiry = -1; // 设置消息用不过期

45.  

46. sendQueue.put(msg, pmo);// 将消息放入队列

47. qMgr.disconnect();

48. } catch (Exception e) {

49. e.printStackTrace();

50. } finally {

51. if (sendQueue != null) {

52. try {

53. sendQueue.close();

54. } catch (MQException e) {

55. e.printStackTrace();

56. }

57. }

58. }

59. }

60.  

61. public void receiveMsg() {

62. int openOptions = MQConstants.MQOO_INPUT_AS_Q_DEF | MQConstants.MQOO_OUTPUT | MQConstants.MQOO_INQUIRE;

63. try {

64. receiveQueue = qMgr.accessQueue(queueName, openOptions, null, null, null);

65. int depth = receiveQueue.getCurrentDepth();

66. System.out.println("该队列当前的深度为:" + depth);

67.  

68. // 将队列的里的消息读出来

69. while (depth-- > 0) {

70. MQMessage rcvMessage = new MQMessage();// 要读的队列的消息

71. MQGetMessageOptions gmo = new MQGetMessageOptions();

72. receiveQueue.get(rcvMessage, gmo);

73. String msgText = rcvMessage.readUTF();

74. System.out.println("消息的内容:" + msgText);

75. }

76. } catch (Exception e) {

77. e.printStackTrace();

78. } finally {

79. if (receiveQueue != null) {

80. try {

81. receiveQueue.close();

82. } catch (MQException e) {

83. e.printStackTrace();

84. }

85. }

86. try {

87. qMgr.disconnect();

88. } catch (MQException e) {

89. e.printStackTrace();

90. }

91. }

92. }

93.  
94.  
95.  

96. public static void main(String[] args) throws MQException {

97. new MqDemo().sendMsg("消息1");

98. new MqDemo().sendMsg("消息2");

99. new MqDemo().sendMsg("消息3");

100. new MqDemo().receiveMsg();

101. }
