[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0043] Spring Cache is a lightweight Java development framework that provides caching functionality. The cache expiration time of cached data can be set during initialization, but in actual application, the cache expiration time needs to be dynamically adjusted according to specific circumstances.
[0044] In the prior art, an expiration time can be added to the name attribute of the cached data, and the logic for reading the original cache name can be modified, for example, "@Cacheable (value = key # 60)", where the expiration time is after the "#", and then the logic for reading the cache name in SpringCache is modified to parse out the time "60", or extended support is provided based on the CacheManager interface of Spring Cache, all of which modify the original logic, making the modified logic incompatible with the original logic, and the cache expiration time configuration of the cached data unstable; you can also add a configuration file, and group the cached data according to the configuration file, configure different cache expiration times for different groups, and parse the cache expiration time according to the configuration, but it is not possible to configure the cache expiration time for each cached data.
[0045] To this end, the present application correspondingly provides a cache expiration time configuration scheme for cached data, which effectively and stably configures the cache expiration time of each cached data.
[0046] See also Figure 1 As shown, the embodiment of the present application discloses a method for configuring the cache expiration time of cached data, including:
[0047] Step S11: adding target annotation attributes corresponding to each cache data in the cache annotation of the Spring Cache cache framework; wherein the target annotation attributes are attributes configured based on the cache expiration time of the cache data.
[0048] In this embodiment, new annotation attributes are added without changing the existing annotation parsing logic of the Spring Cache caching framework to configure different expiration times for different cached data, for example Figure 2A specific cache expiration time configuration diagram of cache data is shown. Based on the cache expiration time configuration attribute of the cache data, the target annotation attribute is obtained, and while being compatible with the original annotation attribute, the target annotation attribute corresponding to each cache data is added to the cache annotation of the Spring Cache caching framework.
[0049] Step S12: extracting the cache expiration time of each cached data from each target annotation attribute.
[0050] In this embodiment, the extraction of the cache expiration time of each cached data from each target annotation attribute includes: extracting the cache expiration time of each cached data from each target annotation attribute using the reflection mechanism in the cache interceptor. The built-in cache interceptor (CacheInterceptor) of the Spring Cache caching framework is extended to add the processing logic of the cache data expiration time. The processing logic is specifically used to extract the cache expiration time of each cached data from each target annotation attribute using the reflection mechanism in the cache interceptor. For example, the cache expiration time I of cache data a, the cache expiration time II of cache data b, and the cache expiration time III of cache data c are extracted from the target annotation attribute A, the target annotation attribute B, and the target annotation attribute C respectively using the reflection mechanism.
[0051] Step S13: Using thread variables to save the cache expiration time of each cache data to a storage medium, completing the configuration of the cache expiration time of each cache data, so as to clean up each cache data based on the cache expiration time of each cache data saved in the storage medium.
[0052] In this embodiment, the use of thread variables to save the cache expiration time of each cached data to a storage medium includes: putting the cache expiration time of each cached data into a thread variable, and saving the cache expiration time of each cached data read from the thread variable to a storage medium. The processing logic of the cached data expiration time is also specifically used to use ThreadLocal (thread variable) to assist in transmitting the expiration time, for example Figure 2 As shown, the cache expiration time of each cache data is put into the thread variable, and then the cache expiration time of each cache data read from the thread variable is saved to the storage medium, and after the cache expiration time of each cache data is put into the thread variable, business operations are also performed to persist the data.
[0053] In this embodiment, before clearing each cache data based on the cache expiration time of each cache data stored in the storage medium, it also includes: writing cache management logic based on cache expiration time in the extended class of the cache interceptor. Add cache expiration time processing logic in doPut() and doGet() of the extended class of CacheInterceptor, that is, write cache management logic based on cache expiration time in the extended class of the cache interceptor.
[0054] It can be understood that without changing the existing functions of the Spring Cache interceptor CacheInterceptor, only extensions are made, which is in line with the open and closed principle of software design; the supported cache types are consistent with Spring Cache and are not limited to specific cache types. It is only necessary to extend its annotation class and a cache interceptor class in the Spring Cache framework, and the design is more concise; the required storage medium can be based on the existing cache storage, and can also be persisted to other storage devices; this embodiment is universal, and other cache functions can be extended through custom annotations.
[0055] In this embodiment, the clearing of each cache data based on the cache expiration time of each cache data stored in the storage medium includes: enabling the cache management logic based on the cache expiration time to clear each cache data based on the cache expiration time of each cache data stored in the storage medium. It is understandable that after the cache management logic based on the cache expiration time is written in the extension class of the cache interceptor, the cache management logic based on the cache expiration time is enabled, so that each cache data can be cleared based on the cache expiration time of each cache data stored in the storage medium.
[0056] In a specific embodiment, the clearing of each cached data based on the cache expiration time of each cached data stored in the storage medium includes: if the current time meets the preset triggering condition of the scheduled clearing task, then clearing each cached data based on the cache expiration time of each cached data stored in the storage medium. The scheduled clearing task triggering condition is set in advance in the background. If the current time meets the preset triggering condition of the scheduled clearing task, the scheduled clearing task begins to execute, that is, the expiration time is taken out from the storage medium to determine whether the cached data is expired. If it is expired, the cached data and its expiration time configuration are deleted, that is, each cached data is cleared based on the cache expiration time of each cached data stored in the storage medium.
[0057] In another specific embodiment, the clearing of each cache data based on the cache expiration time of each cache data stored in the storage medium includes: when a data reading task is received, determining the target cache data corresponding to the data reading task; clearing the target cache data based on the cache expiration time of the target cache data stored in the storage medium. When the cache data needs to be read, it can be determined whether the target cache data a needs to be cleared according to the cache expiration time I of the target cache data a, for example Figure 3 A specific cache data cleaning diagram is shown. If the cache expiration time I has been exceeded, the target cache data a is determined to be expired and is in an invalid state. Therefore, the target cache data a is cleaned, the business is entered to read the corresponding data, and the read data is returned. If the cache expiration time I has not been exceeded, it means that the target cache data a is still valid. Therefore, the data reading task can be responded to, that is, the target cache data a is read from the corresponding cache and the target cache data a is returned.
[0058] In this embodiment, each cache data is cleaned up based on the cache expiration time of each cache data stored in the storage medium, including: reading the cache expiration time of the current cache data stored in the storage medium; determining whether the current time matches the cache expiration time of the current cache data; if they match, deleting the current cache data, the target annotation attribute corresponding to the current cache data, and the cache expiration time of the current cache data. For example, the storage medium stores cache expiration time I of cache data a, cache expiration time II of cache data b, and cache expiration time III of cache data c, wherein cache expiration time II of cache data b is determined as the cache expiration time of the current cache data, and it is determined whether the current time matches the cache expiration time II of the current cache data. If so, it means that the cache data b is in an invalid state, so the current cache data b, the target annotation attribute B corresponding to the current cache data, and the cache expiration time II of the current cache data are deleted; next, the cache expiration time III of cache data c can be determined as the cache expiration time of the current cache data. If the cache expiration time III does not match the current time, it means that the cache data c is in a valid state, so no processing is performed.
[0059] The beneficial effects of the present application are as follows: the present application adds target annotation attributes corresponding to each cache data in the cache annotation of the Spring Cache caching framework; wherein the target annotation attribute is an attribute configured based on the cache expiration time of the cache data; extracts the cache expiration time of each cache data from each target annotation attribute; uses thread variables to save the cache expiration time of each cache data to a storage medium, completes the configuration of the cache expiration time of each cache data, so as to clean up each cache data based on the cache expiration time of each cache data stored in the storage medium. It can be seen that the present application adds target annotation attributes corresponding to each cache data in the cache annotation of the Spring Cache caching framework, that is, while keeping the cache annotation of the original Spring Cache caching framework, adds corresponding attributes configured based on the cache expiration time of the cache data for different cache data, does not need to introduce configuration files, and does not need to modify the original logic of reading the cache name, minimizes the intrusion into the program, and avoids incompatibility after the cache expiration time is configured, that is, realizes effective and stable configuration of the cache expiration time of each cache data.
[0060] See also Figure 4 As shown, the embodiment of the present application discloses a cache expiration time configuration device for cached data, including:
[0061] The attribute adding module 11 is used to add target annotation attributes corresponding to each cache data in the cache annotation of the Spring Cache cache framework; wherein the target annotation attribute is an attribute configured based on the cache expiration time of the cache data;

[0063] The configuration completion module 13 is used to use thread variables to save the cache expiration time of each cache data to the storage medium, and complete the configuration of the cache expiration time of each cache data, so as to clean up each cache data based on the cache expiration time of each cache data saved in the storage medium.
[0064] The beneficial effects of the present application are as follows: the present application adds target annotation attributes corresponding to each cache data in the cache annotation of the Spring Cache caching framework; wherein the target annotation attribute is an attribute configured based on the cache expiration time of the cache data; extracts the cache expiration time of each cache data from each target annotation attribute; uses thread variables to save the cache expiration time of each cache data to a storage medium, completes the configuration of the cache expiration time of each cache data, so as to clean up each cache data based on the cache expiration time of each cache data stored in the storage medium.
