RocketMQ使用过滤器filterServer（4.3版本后）

cd /opt/software/rocketmq/bin
./mqshutdown broker
./mqshutdown namesrv

#开启对filter的支持
enablePropertyFilter=true

cd /opt/software/rocketmq/bin
nohup sh mqnamesrv & (运行后可能会有中断提示，不用管，使用Ctrl+C关闭)

cd /opt/software/rocketmq/bin
nohup sh mqbroker -c /opt/software/rocketmq/conf/2m-noslave/broker-a.properties >/dev/null 2>&1 &

//使用sql来进行过滤
consumer.subscribe("TopicFilter",MessageSelector.bySql(
        "TAGS is not null and TAGS in ('TagB','TagC') " +
        " and index is not null and (index between 5 and 9)"));

String filterCode = MixAll.file2String("过滤类的绝对路径");
System.out.println(filterCode);
consumer.subscribe("TopicFilter","xjf.filter.MessageFilterImpl(类的相对路径)",filterCode);
