我尝试使用Apache Kafka启动一个生产者，它曾经工作得很好，但现在当尝试在CLI中运行此代码时：

./kafka-avro-console-producer --bootstrap-server localhost:9092 --property schema.registry.url=http://localhost:8081/ --topic trainee --property value.schema.id=3

字符串

缺少必需的参数“[topic]”

  memory in bytes per partition>           partition. When records are received 
                                           which are smaller than this size the

                                           of them. This property specifies the

                                           leadership changes. (default: 300000)

                                           the producer.                        
--producer.config <String: config file>  Producer config properties file. Note  
                                           that [producer-property] takes       
                                           precedence over this config.         
--property <String: prop>                A mechanism to pass user-defined       
                                           properties in the form key=value to  
                                           the message reader. This allows      
                                           custom configuration for a user-     
                                           defined message reader. Default      
                                           properties include:

--request-timeout-ms <Integer: request   The ack timeout of the producer        
  timeout ms>                              requests. Value must be non-negative 
                                           and non-zero (default: 1500)         
--retry-backoff-ms <Integer>             Before each retry, the producer        
                                           refreshes the metadata of relevant   
                                           topics. Since leader election takes  
                                           a bit of time, this property         
                                           specifies the amount of time that    
                                           the producer waits before refreshing 
                                           the metadata. (default: 100)         
--socket-buffer-size <Integer: size>     The size of the tcp RECV size.         
                                           (default: 102400)                    
--sync                                   If set message send requests to the    
                                           brokers are synchronously, one at a  
                                           time as they arrive.                 
--timeout <Integer: timeout_ms>          If set and the producer is running in  
                                           asynchronous mode, this gives the    
                                           maximum amount of time a message     
                                           will queue awaiting sufficient batch 
                                           size. The value is given in ms.      
                                           (default: 1000)                      
--topic <String: topic>                  REQUIRED: The topic id to produce      
                                           messages to.
