Ref ISSUE #103

[RongtongJin]

I tried your modify, but it do not work. Because when container.setRocketMQMessageListener was called, the parsed selectorExpression was overwritten.

[RongtongJin]

@liuliuzo Maybe you should delete the code this.selectorExpression = anno.selectorExpression(); in setRocketMQMessageListener method.

[liuliuzo]

@RongtongJin sorry i will build environment and adding test before submit next time. i am not delete this.selectorExpression = anno.selectorExpression(); in setRocketMQMessageListener method. because selectorExpression should have default value '*', other idea is change container.setRocketMQMessageListener(annotation); order in createRocketMQListenerContainer

@liuliuzo It would be helpful to verify if you could add some test in your polish. I would like to follow up and help to merge this pr:-)

[liuliuzo]

@vongosling sorry,i will better improve my pull request quality next time.

Could you modify the class MyExtRocketMQTemplate name, you could assign a concrete name Instead of a name with no actual meaning my**?
