导入jar包

配置dto.properties文件

dto.driverClass = com.mysql.jdbc.Driver
dto.jdbcUrl = jdbc:mysql://localhost:3306/spring
dto.user = root
dto.password = 123456
dto.package = bean
dto.mapper = mapper
dto.tablePrefix = t_

写个main方法生成代码

public class Test {
    public static void main(String[] args) throws Exception {
        DTOHelper dto = new DTOHelper();
        dto.createDto();
    }
}

最后生成的文件
