SchemaExport(cfg).create(boolean script,boolean...

create

public void create(boolean script,
                   boolean export)

Run the schema creation script. Parameters: script- print the DDL to the consoleexport- export the script to the database

drop

public void drop(boolean script,
                 boolean export)

Run the drop schema script. Parameters: script- print the DDL to the consoleexport- export the script to the database

execute

public void execute(boolean script,
                    boolean export,
                    boolean justDrop,
                    boolean justCreate)

create()和drop（） 都是调用的execute()方法，create (boolean script,boolean export)中

script 控制 是否将建表语句输入到控制台，export 控制是否将 建表语句输入到 数据库，实际上控制是否建表！

drop 方法同理！
