4、执行反向工程，即根据数据库表生成相应的.aj文件，如果是第一次执行的话，可能会提示JDBC driver not available for ‘com.mysql.jdbc.Driver'，如下

roo> database reverse engineer --schema feedback_schema --package ~.domain
Searching 'com.mysql.jdbc.Driver' on installed repositories
1 matches found with 'com.mysql.jdbc.Driver' on installed repositories
ID   BUNDLE SYMBOLIC NAME                                    DESCRIPTION
--------------------------------------------------------------------------------
01   org.springframework.roo.wrapping.mysql-connector-java   Spring Roo - Wrapping - mysql-connector-java
--------------------------------------------------------------------------------
[HINT] use 'addon info bundle --bundleSymbolicName' to see details about a search result
[HINT] use 'addon install bundle --bundleSymbolicName' to install a specific add-on version
Located add-on that may offer this JDBC driver
JDBC driver not available for 'com.mysql.jdbc.Driver'

5、根据提示安装org.springframework.roo.wrapping.mysql-connector-java，执行命令如下
roo> addon info bundle --bundleSymbolicName org.springframework.roo.wrapping.mysql-connector-java

8、添加日志

logging setup --level INFO --package ALL_SPRING
