Groovy轻松入门——Grails实战基础篇(4)

 

ok.gsp:

9，修改demo/grails-app/conf/ApplicationBootStrap.groovy，将一个User实例保存到数据库(grails自带hsqldb和jetty)中，内容如下：

class ApplicationBootStrap { def init = { servletContext -> new User(name: "demo",password: "123456").save() } def destroy = { } }

 

10，在“命令行”中，输入“grails run-app”，运行我们的Web应用，输出如下：
