List of issuesThe list Builder can create a table directly,However, if there are 1 million elements in a table, the table takes up too much space,And often we just need to access the first few elements, the vast majority of elements behind the space wasted.GeneratorIf the list element can be calculated according to an algorithm, then we can continuously deduce the subsequent elements in the process of the loop. Instead of creating the entire list at the beginning.This saves a lot of space.The me

MyBatis Generator (MBG) is a MyBatis code generator that helps us generate corresponding entity classes, XML mapper files, interfaces, and help classes based on the design of tables in the database (that is, we can use this class for simple crud operations). This avoids the need to manually create the corresponding classes and XML files for each table of data, which saves us a lot of time to develop functio
