Abstract

The embodiment of the invention provides a transaction processing method and a Java virtual machine. The method comprises the steps of: receiving a request of a unit for calling a certain function, and calling a module object capable of realizing the function through a weak reference object; returning the module object to the unit so as to carry out transaction processing; and judging whether the module object is weakly reachable, if so, clearing the module object. According to the transaction processing method and the Java virtual machine provided by the embodiment of the invention, when a module management container receives the request for calling a set-up function sent by the unit, the module object capable of realizing the set-up function is called through the weak reference object, and after the unit calls the module object to perform transaction processing, if the module object is weakly reachable, the module object can be cleared by the virtual machine, so that the memory resource occupied by the module can be released in time, and the memory resource is saved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a business processing method and a Java virtual machine. Background technique [0002] In a virtual machine using Java or other programming languages, the virtual machine judges whether the memory can be released according to the garbage collection algorithm. The judgment method is the reachability of the object. If the object is reachable, it cannot be released. If the object is unreachable need to be released. When the virtual machine is running, objects directly or indirectly referenced from the root set of references are reachable objects, and other objects are unreachable objects. Unreachable objects are garbage and need to be collected to free memory. [0003] Usually, "Root set of references" is used as the starting point of garbage collection. Objects that can be traversed are reachable, and objects that cannot be traversed are unreachable. Among them, "Root set of r...
