MyBatis Tips[SQL mapper framework for Java]

MyBatis is a first class persistence framework with support for custom SQL, stored procedures and advanced mappings in Java.

I would like to introduce some tips about MyBatis.

🐡 About multiple arguments in DAO

When defining the interface in Dao file and having multiple arguments, you should use @Param xxx.

public List getAllbyDate(@Param("date") Date date, @Param("myid") int myid);

If there are multiple arguments and you do not use @ Param, the error is as follows:

org.apache.ibatis.binding.BindingException: Parameter 'myid' not found. Available parameters are [1, 0, param1, param2]

Please be careful.

🐯 Special Thanks
