The invention discloses a data access method, a message receiving resolver and a system, and belongs to the field of network storage. The method comprises the following steps of: receiving a data access request; determining a hard disk accessed by the data access request according to the data access request; and sending the data access request to a message queue associated with the hard disk so that the hard disk completes data access according to the data access request. The message receiving resolver comprises a receiving module, a determining module and a sending module. The system comprises the message receiving resolver, at least one hard disk and the message queue associated with each hard disk. One message queue associated with the hard disk is generated for each hard disk, and the received data access request is distributed to the corresponding message queue to wait in line and processed in parallel, so that the waiting time delay of each data access request is uniform when a large amount of data access requests simultaneously access the storage system, and quick access of data in multiple channels and multiple hard disks is realized.

The cache control unit 15 of the mobile terminal 10 receives an access request for an instance of an object that specifies data to which applications 13 refers, and in the case that an instance of the object does not exist, creates an instance of the object and a counter. In addition, an instance of a reference setting class is created, the reference that refers to the instance of the requested object is set and the result is returned to the application 13, and the counter is incremented by 1. In the case that a release notification for the instance of the reference setting class is received, the counter is decremented by 1, and when the counter has reached 0, the instance of the object is released.
