Stored procedure call and running process of mybatis source code analysis

In this article, let's learn the usage and running process of mybatis calling stored procedures. First, we create a simple stored procedure

In fact, the meaning of this stored procedure is relatively simple, that is, enter age, and then execute select count (*) from users where users age = age into user_ count； Get the number of people whose age is equal to age and assign it to user_ Count is still relatively simple.

The next step is the call of the stored procedure. The call of the stored procedure can be completed by executing the following commands.

Next, let's look at how to call stored procedures using mybatis.

userMapper. XML add stored procedure call configuration:

Main function:

Operation results:

The final execution process is in DefaultResultSetHandler. There is a difference between calling ordinary SQL and stored procedure. The execution of SQL statement is CallableStatement.
