AIDL+MemoryFile anonymous shared memory realizes cross-process large file transfer
Note: The content of this article is reproduced from the following article: Using AIDL to efficiently transfer large files across processes AIDL AIDL is a way to implement inter-process communication (Inter-Process Communication) in Android. AIDL‘s data transmission mechanism is based on Binder. Binder has a limit on the size of the data to be transmitted. […]
The use of Android anonymous shared memory
Note: The content of this article is reproduced from the following article: The use of anonymous shared memory in Android How does the drawing of Android View pass data to SurfaceFlinger? When communicating across processes, how to transfer data larger than 1MB? Using Anonymous shared memory (Ashmem) is a good choice. It can not only […]
Hibernate + Springboot implements the @Filter filter to automatically add conditional filtering. How to implement sprinboot multi-tenancy (shared table, by adding tenant_id)
Hibernate + Springboot implements @Filter filter to automatically add conditional filtering After three days and three nights of torture, I finally solved this requirement. First of all, this requirement is generally implemented through annotations. So the first step is to write an annotation by hand: @Target({<!– –>ElementType.PARAMETER, ElementType.METHOD})//The target location for annotation placement, METHOD can […]

Wireshark uses command line to analyze packets
1, those situations require the use of the command line Wireshark provides too much information at once. Use command line tools to limit the information printed out so that only relevant data is displayed, such as IP addresses on a single line. The command line tool is suitable for filtering packet capture files and providing […]
