mybatisplus jdbcType=INT

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.
