The invention discloses a method and device for implementing a multi-channel message bus. The method comprises the following steps: obtaining various message services provided by a server background,respectively creating data channels corresponding to the message services in a message bus; when a request message sent by a client is received, parsing the request message to obtain target message service requested for obtaining in the request message, then obtaining target message data corresponding to the target message service, and sending the target message service to the client through a corresponding data channel. Compared with the prior art, the method provided by the embodiment of the invention has the advantages that the independent data channels are created for the message servicesin the message bus, so that the data transmitted in the message bus can be dispersed to all data channels, a communication bottleneck that causes data congestion of the message bus can be avoided effectively, and thus improving the transmission efficiency of the message bus.
