如何运行com.moonspider.dbmap.GenerateConfig

从命令行？

例如，要使用MySQL数据库运行，请按以下方式运行：

java -cp /path/to/lib/mysql-connector-java-3.1.14-bin.jar:dbmap-r12.jar \
com.moonspider.dbmap.Generator -t jpa -d entities -url jdbc:mysql://localhost/jpagen \
-pkg com.xyz.data.entity -u user -p pass -driver com.mysql.jdbc.Driver
