我在我的服务器上构建了一个rocketmq服务,它是2m-noslave集群,它可以向rocketmq发送消息,但我的消费者无法接收消息,有人告诉我哪里错了,thinks...this是我的消费者CLass代码:
public class Consumer{
public static final String CONSUMER_GROUP_NAME = "broker-b";
public static final String CLUSTER_ADDR = "120.27.128.207:9876;120.27.146.42:9876";
我在使用Rocket MQ(v4.1.0-孵化)客户端时遇到严重问题,如下所示:
2017-10-16 16:18:12:457[ERROR][SimpleProducer$1.onException(SimpleProducer.java:44)] - send message to mq fail:
org.apache.rocketmq.remoting.exception.RemotingTooMuchRequestException: invokeAsyncImpl invoke too fast
at org.apache.rocketmq.remoting.netty.N
我正在创建一个Rails应用程序,并刚刚添加了一个文件(app/spec/models/test_spec.rb ),其中包含5个新的rspec测试:
describe Topic do
describe "scopes" do
before do
@public_topic = Topic.create # default is public
@private_topic = Topic.create(public: false)
end
describe "publicly_viewable
我正在尝试创建一个简单的网页,它显示从web服务接收的数据。
@Service
@Transactional
public class TopicService {
@Autowired
private TopicRepository topicRepository;
public int saveTopic(Topic topic){
return topicRepository.save(topic).getId();
}
public Iterable<Topic> findAllTopics(){
我的Django项目中有以下模型(models.py):
class Topic(models.Model):
id = models.AutoField(primary_key=True)
title = models.CharField(max_length=140)
def __unicode__(self):
return self.title
class ArgumentElement(models.Model):
id = models.AutoField(primary_key=True)
contents = mode
