Background With the rapid development of network technology and computer technology, most of internet applications currently adopt a structure that a client is connected with a server to realize that the client obtains information expected by a client user from the server. To avoid clients from repeating creation of server connections multiple times when they need to use the server, the server typically provides a number of connections to different clients in a connection pool. In the related art, when receiving a connection request from a client, a server judges whether a connection pool has an idle connection or not, if so, receives the connection request and allocates connection resources for the client, and if not, refuses the connection request. However, once the client that has established a connection with the server is in a busy state, all the connections in the server connection pool may be occupied at the same time, but if the client is not automatically disconnected after the client transitions to the idle state, the connections in the server connection pool are continuously occupied, which results in that the server connection pool cannot provide connection resources for other clients. Disclosure of Invention The application provides a method, a device, electronic equipment and a computer readable storage medium for allocating connection resources of a server connection pool, which are used for solving the problem that the connection in the server connection pool is continuously occupied under the condition that a client is not automatically disconnected after the client is converted into a service idle state in the prior art, so that the server connection pool cannot provide connection resources for other clients.
