Expected Result

期待的结果是调用 sayHello

Just put your stack trace here!

I can't reproduce this issue in my environment.According to the appearance of NullPointerException of the method "sayHello" of DemoServiceComponent,it seems like it is a problem that you can't get a bean named "demoServiceComponent" from the Spring container.
You can try following steps:
1.check if the maven dependency of spring in the external libarary ,mine is 5.2.8.If your version is wrong,maybe it is a bug of ide.And you can try to refresh the maven.
2.you can set a breakpoint after the consumer invoke the method sayHello,and put your debug stack trace here.

your zookeeper version is too hign,dubbo 's zk client version is 3.4.13

I tried using 3.4.13/3.4.14 with jdk15, and it stills problem as above.
I tried using zookeeper 3.4.3, and it works!
