The invention relates to the technical field of
software development, and discloses an inter-component communication method and device,
electronic equipment and a
system.The method comprises the steps that when a service calling request of any first
service component is detected, the service calling request of any first
service component is searched through a service searching method set by an intermediate
service component; searching whether a target service instance complying with a target
service protocol corresponding to the service calling request exists in a service instance
pool corresponding to the intermediate service component; wherein the target service instance is a service instance corresponding to the second
business component; and when finding that a target service instance complying with a target
service protocol corresponding to the service calling request exists in a service instance
pool corresponding to the intermediate service component, obtaining the target service instance to call a business service requested by the service calling request. Visibly, the low-
coupling communication between the service components can be realized by setting the intermediate service component, so that the communication mechanism between the components is optimized, and the communication efficiency and flexibility between the components are improved.
