What is the interface binding of MyBatis? What are the ways to implement it?

Interface binding is to define an interface arbitrarily in MyBatis, and then bind the methods in the interface to SQL statements. We can call the interface methods directly, so that we can have more flexible choices and settings than the original methods provided by SqlSession.

Interface binding can be implemented in two ways

By annotating binding, you add @ Select, @ Update and other annotations to the interface's methods, which contain Sql statements to bind

Bind by writing SQL in xml. In this case, to specify that the namespace in the xml mapping file must be the full path name of the interface. When the Sql statement is relatively simple, use annotation binding, when the SQL statement is more complex, use xml binding, generally use xml binding more.
