Question

我使用Apache Apollo -1.1作为我的JMS代理。

在其中，我试图在JMS标题上使用选择器，它在值中包含冒号。 JMS头如下：

SYMBOL=USDGBP17MAYFUT::CDE

当我尝试使用消息选择器

时

symbolSelector = "(SYMBOL='USDGBP17MAYFUT::CDE')"

OR

symbolSelector = "(SYMBOL LIKE 'USDGBP17MAYFUT!:!:CDE' ESCAPE '!')"

未选择正确的讯息。

如果我从JMS标题中的符号中删除冒号，并且相应地在symbolSelector中删除，则过滤工作正常。

请帮我使用正确的选择器，因为我需要带有冒号的符号。

更新

我尝试了以下作为转义字符（基于彼得的输入），但没有工作：

symbolSelector= "(SYMBOL LIKE 'USDINR17JUNFUT\\$:\\$:CDE_FO' ESCAPE '\\$')"

和

symbolSelector= "(SYMBOL LIKE 'USDINR17JUNFUT\\!:\\!:CDE_FO' ESCAPE '\\!')"

但我继续得到例外：

org.fusesource.stomp.client.ProtocolException: Received an error: Invalid selector expression:  (MESSAGE_TYPE='REGISTER_REQUEST') AND (SYMBOL LIKE 'USDINR17JUNFUT\$:\$:CDE_FO' ESCAPE '\$')

Answer 1

首先，Apache Apollo 1.1是现已停产的产品的早期版本。面对问题，我会考虑升级它。

无论如何，带冒号的选择器就像任何其他选择器一样。上面的两个语句在使用带有Apollo 1.1代理的ActiveMQ 5.8 / OpenWire v8 JMS客户端时都没有问题。它必须是别的东西。

测试命令以使用带选择器的msg。逃脱！适用于zsh，而不是Java / JMS。

for(int a=0, b=5 ; a<=5 ; a++,b--){
    // do your stuff here
}

在JMS选择器中转义冒号--Apache ActiveMQ Apollo
