ObjectiveThe previous article, said MyBatis introduction, talked about the MyBatis has two basic configuration files, one to configure the environment information, one to write SQL statements. The former I named it config.xml,config.xml content is:

class index, parent class index, and interface index collectionThe above describes the class file, the magic number from the beginning, the minor version number, the major version number, the constant pool entry, the constant pool, the access flag.

According to the SQL standard, both the catalog and schema are abstract concepts in a SQL environment and can be understood as a hierarchy in a container or database object namespace, primarily to address naming conflicts. Conceptually, a database

The class fully qualified name is java.lang.ClassThe class class object stores the classes ' fully qualified name, attributes, methods, and parent classes of the other class.Suppose a class A is defined,When creating a Class A object, you also
