Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] figure 1 A resource object leak detection method provided by an embodiment of the present invention is shown, including:

[0025] S11. Scan the queue of weakly referenced objects, determine the target weakly referenced object, and analyze the target weakly referenced object to obtain corresponding metadata information;

[0026] S12. If the status information in the metadata information is not closed, determine the location information of the corresponding target resource object according to the metadata information, and determine the leaked resource object according to the location information.

[0027] Regarding step S11 and step S12, it should be noted that, in ...

Abstract

The embodiment of the present invention provides a resource object leakage detection method and device. The method comprises the steps of scanning the queue of weakly referenced objects, identifying the target weak reference object, parsing the target weak reference object to obtain the corresponding metadata information, if the state information in the metadata information is an unclosed state, determining the position information of the corresponding target resource object according to the metadata information, determining the leaked resource object according to the position information, andfinding the resource object which has not been recovered successfully through the weak reference object, so that the resource leak detection is accurate.

Description

technical field [0001] The invention relates to the technical field of data services, in particular to a resource object leakage detection method and device. Background technique [0002] In many business systems, the problem of slow response or even downtime of the business system often occurs because resource objects (such as database connection objects) are not closed. Once a fault occurs, the location is extremely complicated, which seriously affects the stable operation of the production system. Java technology plays a pivotal role in many web business systems, how to quickly locate the location of resource leak objects in the Java virtual machine has become a very challenging problem. [0003] The difficulty of this problem lies in how to judge whether the resource object is closed after garbage collection, that is, how to judge whether the resource object has executed the close method after the resource object is recycled. After the object is recycled in the Java vi...
