我正在尝试在Apache Geode上创建连续查询。但是低于例外
Caused by: java.lang.IllegalStateException: CqService is not available.

我已经创建了我的区域使用
create region --name=Student --type=REPLICATE --enable-statistic=true --enable-subscription-conflation=true
请在下面找到我用于创建查询服务和注册CQ的代码
@Bean
QueryService getQueryService() throws CqException, QueryInvalidException, CqExistsException, CqClosedException, RegionNotFoundException{
ClientCache cache =appContext.getBean(ClientCache.class);
QueryService qservice= cache.getQueryService();
CqAttributesFactory cqf = new CqAttributesFactory();
cqf.addCqListener(new CqListener() {
@Override
public void close() {
// TODO Auto-generated method stub
}
@Override
public void onEvent(CqEvent aCqEvent) {
// TODO Auto-generated method stub
System.out.println("Event Recieved !");
}
@Override
public void onError(CqEvent aCqEvent) {
// TODO Auto-generated method stub
}
});
CqQuery studentTracker=qservice.newCq("StudentQuery","SELECT name from /Student where rollNo==0",cqf.create());
// qservice.executeCqs("/Student");
studentTracker.execute();
// System.out.println(qservice.getCqStatistics().numCqsActive()+" *****************");
studentTracker.close();
return qservice;
}
如果有人能分享Gemfire连续查询的工作示例,那将是一个很大的帮助
我从Geode用户列表中得到了上述问题的答案。我使用了错误版本的GeodeM2发布后支持连续查询功能
