java - IBM 字符集 header 导致异常

Question

我们有一个 Spring Integration 流程，它使用 Websphere MQ Manager 队列中的消息。这些消息经过一个简单的过程，然后放入另一个队列(在同一个 MQ 管理器中)。

当我们尝试将消息写入最终目标队列时，出现以下错误:

Caused by: javax.jms.JMSException: MQJMS1006: invalid value for 'JMS_IBM_Character_Set': 'IBM850'.

        at org.springframework.integration.handler.AbstractMessageHandler.handleMessage(AbstractMessageHandler.java:127) ~[spring-integration-core-4.2.0.RELEASE.jar:?]

我们从初始队列中获取的消息具有以下 IBM 特定 header :

JMS_IBM_Character_Set=IBM850,
JMS_IBM_MQMD_CodedCharSetId=850,
JMS_IBM_Encoding=17,
JMS_IBM_PutApplType=11,
JMS_IBM_Format=        ,
JMSXDeliveryCount=1,
JMS_IBM_PutTime=12534150,
JMS_IBM_MsgType=8

当我们尝试将处理后的消息写入最终的 Websphere MQ 队列时，它们仍然存在。

该项目正在使用以下 IBM MQ 依赖项 jar:

compile 'com.ibm:com.ibm.mq:7.0.1.3'
compile 'com.ibm:com.ibm.mqjms:7.0.1.3'
compile 'com.ibm:com.ibm.mq.jmqi:7.0.1.3'
compile 'com.ibm:com.ibm.mq.headers:7.0.1.3'

解决此异常的正确方法是什么？我们应该:

1. 在写入之前从消息中删除所有 JMS_IBM_XXX header 到最终的 Websphere MQ 队列？
2. 使用不同版本的 jar？
3. 完全做点别的事情吗？

在从 Websphere MQ 队列获取消息并最终将其写入另一个 Websphere MQ 队列的任何其他流中，我们似乎没有遇到此问题。

引用WebSphere MQ 7.5 - MS_IBM_Character_Set :

Prior to WebSphere® MQ V7.5, applications using WebSphere MQ messaging provider migration mode could set the JMS_IBM_Character_Set property of a message to a numerical Coded Character Set Identifier.

When the message was sent, the Coded Character Set Identifier stored in the JMS_IBM_Character_Set property was mapped to the MQMD field CodedCharacterSetID.

When using the WebSphere MQ V7.5 classes for JMS, a JMSException containing the message:

MQJMS1006: invalid value for 'JMS_IBM_Character_Set': '<number>'

is thrown if an application tries to send a message that has the JMS_IBM_Character_Set property set to a numerical Coded Character Set Identifier.

The JMS_IBM_Character_Set property must be set to the Java character set string that maps to the Coded Character Set Identifier that the application wants to use. For more information, see Mapping JMS fields onto WebSphere MQ fields (outgoing messages)

由于您使用的是 7.0.1.3 版本，而不是 7.5 或更高版本，因此该值必须是“数字 Coded Character Set Identifier”，这意味着它应该是 850(数字)，而不是 IBM850。

在版本 7.5 中，它应该是 IBM850。
