Article Introduction：1. Definition of file mapping File mapping is a mechanism that maps files on disk to the virtual memory space of a process. In this way, the process can read and write files directly through the memory address without having to go through regular system calls such as read and write. In file mapping, we use the Linux mechanism to connect the file and the virtual memory of the process, so that the process can directly read and write file data in the memory without directly accessing the disk. This mechanism provides a more efficient file access method and also simplifies the file operation process. File mapping is often referred to as memory mapping, and the two are often the same. Memory mapping covers the operation of mapping files into memory and mapping anonymous memory into the process address space. File mapping is memory mapping

This function returns a byte slice representing the mapped area, allowing read and write access, and sharing modifications with the file. Using syscall.Munmap to unmap can improve read and write performance. As shown in practical cases, memory mapping is much faster than traditional reading methods.

Article Introduction：This article mainly introduces the basic class mapping and object relational mapping of Hibernate mapping in detail. It is of great practical value. Friends in need can refer to it and recall some of the things we did when we didn’t learn ssh. When we created the database tables, the first step was to build the database. Model the E-R diagram, then build the relationship model through the entity model, and then create the corresponding table. There are three types of relationships between entities, one-to-one, one-to-many (or many-to-one), and many-to-many. Now, if we want to map the corresponding table based on the class, we can only map the database table through the relationship between classes and mapping files. us...
