数据库逆向

Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.7:generate (default-cli) on project mall: Execution default-cli of goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.7:generate failed: Exception getting JDBC Driver

怎么解决？？
讲句真心话，这里的操作真溜，问了个工作三年经验的java，人家都是手敲，这里一键生成，接着各种改错，实际项目能用吗？到时各种改错不会耽误事？
