Automatic generation of DAO, Model, mapping related files using Mybatis-generator

Recently, I have been learning the SSM framework, and today we have a question about mybatis generation and record it.

http://blog.csdn.net/zhshulin/article/details/37956105, I tested it on this blog.

First introduce MyBatis belongs to semi-automatic ORM, in the use of this framework, the greatest amount of work is to write mapping mapping files, because manual writing is easy to make mistakes, we can use Mybatis-generator to help us automatically generate files.

3. Conduct the test

Hold down the SHIFT key in the directory and right-click the "Open command Window Here" to copy and paste the file code of the generated statement. This one is not mentioned in the blog, but bitter me, but fortunately found another blog, is the solution of the mystery. Http://www.cnblogs.com/smileberry/p/4145872.html

Entering statements on the command line

Java-jar Mybatis-generator-core-1.3.2.jar-configfile Generatorconfig.xml-overwrite

4. If you encounter such a wrong workaround　　

When the use of MyBatis generated when encountered problems, the preamble does not allow the content of the problem, if there is such a problem, need to open with notepad++ tool, choose the format to UTF-8 no BOM format encoding , then run the solution, the principle is to XML file replaced by UTF-8 format will have a BOM header Java read the time will be error
