Spring IO Platform as the first line of the spring site to address version dependencies in the Spring project portfolio

Brief introduction:Spring IO platform is the first item in the spring website. It integrates the core API of spring into a platform for modern applications. Provides version dependencies in the spring project portfolio. These dependencies are tested and can be guaranteed to work correctly.Why should I use it?

Purpose of adding spring IO platform:Avoid the issue of versioning conflicts between your own project's external dependencies (external dependencies). For more details see: Spring IO Platform OverviewSpecific procedures: Step1, add spring

Resolving jar Package Dependencies: Spring IO platform Launch BOM

As a result, depending on the module or external integration, dependent processing needs to correspond to the respective version number. For example,

Analysis of IO Model-blocking, non-blocking, IO multiplexing, signal driven, asynchronous IO, synchronous IO

, nonblocking I/O, and I/O multiplexing models are synchronous I/O models, because in the process of waiting for the data, the processes in these three models do not do anything else, even if the non-blocking polling can be considered as a synchronization. The book also argues that the signal-driven I/O model is synchronous I/O, which says that POSIX defines the synchronous IO operation as "causing the request process to block until I/O operation is c

Background: Pio DMA interrupt polling The speed of early I/O devices is not too high compared with that of CPU. The CPU periodically polls the IO Device once to see if there are any processing requirements. If yes, it will be processed and then return to continue working. So far, the floppy disk still keeps this round robin method.With the rapid increase in CPU performance, this inefficient way of working wastes a lot of CPU time. As a result, interru

Linux System Management of IO ports and IO memory

I. I/O portA port is the address of a register in an interface circuit that can be accessed directly by the CPU. Almost every peripheral is made from a register on a read-write device. The CPU sends commands to the registers in the interface circuit through these addresses, namely ports, to read the status and transmit the data. Peripheral registers, also known as "I/O ports", typically include: control registers, status registers, and data registers, and the registers of a peripheral are usuall
