Abstract

The invention relates to the technology of a Java virtual machine, in particular to a data checking method and device of a Java virtual machine, wherein the data checking method of the Java virtual machine includes the following steps:(1) obtaining a check label of data to be visited, wherein the check label consists of a check code, data source information, and time information used to identify the last check time of the data;(2) determining whether or not to check the data to be visited according to the time information and / or the data source information;(3) checking the check code of the data to be visited if checking to the data to be visited is determined. The data checking method and device of the Java virtual machine can simplify the data check process of the Java virtual machine under certain fault-tolerant conditions.

Description

technical field [0001] The invention relates to Java virtual machine technology, in particular to a Java virtual machine data verification method and device. Background technique [0002] A virtual machine is an abstract computer, which is realized by simulating various computer functions on an actual computer. The Java Virtual Machine (Java Virtual Machine, referred to as JVM) is an abstract computer that runs all Java programs and is the operating environment of the Java language. [0003] During the running of the Java virtual machine, there may be some errors in the data accessed by the Java virtual machine. In order to make the Java virtual machine run normally, it is necessary to verify the data in the Java virtual machine. In the prior art, there are multiple methods for verifying the data in the Java virtual machine. Take a more commonly used method as an example: in order to verify the data in the Java virtual machine, the Java virtual machine heap and A check bit...
