In related technologies, the lock is usually set in the database where the resource is located, that is, the database provides the lock mechanism. However, in this way, when the database locks a certain resource (such as a table item), it directly locks the database resource. At the same time, other non-related businesses will be denied access to this resource, which will affect the efficiency of business execution and make the database performance low

The invention discloses an access control method and an access control device. The access control method comprises the following steps: receiving a first lock acquisition request sent by a first client, wherein the first lock acquisition request comprises a first lock element and a second lock element which correspond to the first client; establishing a first lock which corresponds to the first client and comprises the first element and the second lock element which have a corresponding reaction, and returning a lock acquisition success response to the first client so that the first client accesses resources of a database; receiving a second lock acquisition request sent by a second client, wherein the second lock acquisition request comprises a first lock element and a second lock element which correspond to the second client; if the first lock element in the second lock acquisition request is the same as that in the first lock acquisition request, indicating that data access conflict happens and returning a lock acquisition failure response to the second client, so that the second client side stops accessing the resources of the database. According to the technical scheme provided by the embodiments disclosed by the invention, the business processing efficiency is improved.
Description
technical field [0001] The present disclosure relates to network technology, in particular to an access control method and device. Background technique [0002] When a resource is shared between different systems or different hosts of the same system, it is necessary to prevent the above-mentioned different systems or hosts from accessing the resource at the same time, resulting in inconsistent data in the resource. At this time, the resource needs to be locked. The role of the lock That is, for example, when a host accesses a resource, the simultaneous access of another host is denied. In related technologies, the lock is usually set in the database where the resource is located, that is, the database provides the lock mechanism. However, in this way, when the database locks a certain resource (such as a table item), it directly locks the database resource. At the same time, other non-related businesses will be denied access to this resource, which will affect the efficien...
