@Segment Annotation

Marks an interface method and defines a SQL snippet.

Example: define and reuse a column list

@SimpleMapper
public interface UserMapper {
    // Method name becomes the SQL snippet name
    @Segment("user_uuid, user_name, login_name, login_password, email, seq, register_time")
    void user_do_allColumns();

    // If you use a string array, elements are joined with spaces
    @Insert({
            "insert into user_info (@{macro,user_do_allColumns})",          // use the macro rule to reference the snippet
            "values (#{userUuid}, #{name}, #{loginName}, #{loginPassword}, #{email}, #{seq}, #{registerTime})" })
    int createUser(UserInfo tbUser);
}

• The createUser method references the SQL snippet defined by user_do_allColumns using the macro rule.
