Convert snake case to camel case in dao automatic generation tool.

[daisukenishino2]

Requirement

This need arises when the criteria of DDL is a snake case
and the criteria of programming language is a camel case.

Target of fix

In the measures to convert the table name and column name of the definition file, not only code but also generated SQL is changed, so I felt better to fix it at the code level.
