Spring Consolidated JMS (i)-Basic article

　　

RMI uses synchronous communication, and JMS uses asynchronous communication.

There are two main concepts in JMS: The message broker and the destination (destination).

　　

　　

The disadvantage of synchronous communication, which can be solved by using JMS:

　　　　　　

Run Apache-activemq-5.10.0-bin[1]\apache-activemq-5.10.0\bin\win32 under Activemq.bat to start the JMS service.

In order to eliminate redundant JMS code, such as establishing a connection, exception handling, etc., we should use Jmstemplate to send and receive messages.

Similar to JdbcTemplate, Jmstemplate captures check-time exceptions, encapsulates them, and throws them in the form of non-check exceptions.

　　

Code to send the message:

@Component ("Producerserviceimpl") Public classProducerserviceimplImplementsProducerservice {Privatejmstemplate jmstemplate; Public voidSendMessage (Destination Destination,FinalString message) {jmstemplate.send (destination,NewMessagecreator () { PublicMessage CreateMessage (Session session)throwsjmsexception {returnsession.createtextmessage (message);        }            }); }              Publicjmstemplate getjmstemplate () {returnjmstemplate; } @Resource Public voidsetjmstemplate (jmstemplate jmstemplate) { This. jmstemplate =jmstemplate; }}
