Detailed Description
For a clearer understanding of the contents of the present invention, reference will be made to the accompanying drawings and examples.
The calling between the client program and the server program needs to be assisted by the client stub and the server stub to communicate and call, the socket is used for communicating between the client stub and the server stub, and when the client calls one server for multiple times, the server stub needs to process for multiple times to influence the calling time. Data can be accessed through a responsive caching technology, and the condition of no blocking and disconnection is ensured by using responsive distributed subscription and responsive subscription on IO operation related to data access. The following logic is completed before the client invokes the server stub: and receiving the high-frequency request, judging whether the existing request exists in the cache component, simultaneously using response type processing to obtain a result from the cache component for the existing data, finishing the processing and returning a response to the client stub.
The first aspect of the present invention relates to a responsive RPC calling method based on cache storage, which has a step flow as shown in fig. 1, and includes:
and S1, receiving the remote calling request. And during RPC communication, calling RPC stub processing by the client program and initiating remote calling.
S2, the first responsive thread is used for issuing the remote calling request. The client side initiates a request with high frequency to responsively publish the data to the subscriber and release the current client thread.
S3, using the second thread to query whether the cache stores the corresponding cache result corresponding to the remote invocation request, preferably, by using the key name to match the remote invocation request. The key name preferably comprises an interface name and a calling method, the subscriber judges whether the interface name + method is used as the key name to be stored in a cache after starting other thread responsive subscriptions, finds a corresponding cache object, and if a request sent by the client has the corresponding cache object < key, value >, the data is returned to the client program from the cache storage.
And S4, when the cache storage is inquired to store the corresponding cache result corresponding to the remote call request, directly returning the corresponding cache result from the cache storage, and releasing the first thread and the second thread.
S5, when the cache storage is inquired that the corresponding cache result corresponding to the remote call request is not stored, calling the corresponding result from the remote service application according to the remote call request, and releasing the first thread and the second thread.
And S6, acquiring corresponding result data of the remote service application by using the responsive third thread.
And S7, storing corresponding result data of the remote service application into a cache memory by using a fourth thread, storing the result in the form of a key name and a key value to form a cache result, and releasing the third thread and the fourth thread.
When the method is executed, the algorithm of the CaffeineCache is used by default when the switch of the cache component is started, different cache strategies need to be selected according to different application scenes in a multithreading high-concurrency scene, and the cache side rate can be configured at different levels. In a preferred embodiment, the SPI of the Cache may be increased to provide a Cache interface for a Cache selectable algorithm, for example, the selectable algorithm includes: LRU, FIFO, Expire algorithm, etc., with optional parameters in the algorithm specified by the xml configuration file. In another preferred embodiment, a cache mechanism may be additionally configured and used, and may be divided into different cache levels: (1) the client can configure a global cache policy, and all service references start the cache; (2) caching policies can be configured through the interface level referenced to a certain service; (3) and a caching strategy started for a single method is supported, so that flexible application is realized.
