Java ORM code for study

Usage:

1. Add annotation to the table class: Table, Id and Column;
2. Add a child class for the JdbcUtils class;
3. Initialization the child class by uri, username, password and parameters array;
4. Use JdbcUtils#Connection() function to connect to the MySQL database;
5. You can use insert, updateById, deleteById and selectById;
6. You can use delete and select function;
7. NOW you can use setAutoCommit(), commit(), rollback(), rollback(sp) and getSavepoint() to transactional.

Note:

1. If you MySQL database have used datetime, it can only be converted into String;
2. It supports int, Integer, double, 'DoubleandString`.
3. The function select has a parameter where, equals SQL's, but now it is only support =. The delete function also.
