MyBatis-Plus: Using jdbcType='INT' for Database Columns

The 'jdbcType' attribute in MyBatis-Plus is used to specify the JDBC data type for a particular column in a database table.

For example, if you have a column named 'age' in your table and you want to specify its JDBC data type as INT, you can use the 'jdbcType' attribute like this:

@TableField(jdbcType = JdbcType.INTEGER)
private Integer age;

This tells MyBatis-Plus to map the 'age' column to the INT JDBC data type when performing database operations.
