Groovy轻松入门——Grails实战之Web Flow篇
Spring Web Flow是Spring家族中的一位成员,他能简化Web应用的开发。在Grails0.6中就集成了Spring Web Flow这一Web应用开发利器。下面通过一个实例向大家展示一下在Grails中如何方便的使用Spring Web Flow。

2,“cd WebFlowDemo”,进入工程目录
3,“grails create-domain-class User”,创建一个域类User,输出如下
D:\_DEV\grails_apps\WebFlowDemo>grails create-domain-class User

4,将grails-app\domain\User.groovy修改为如下内容:
class
User
implements
Serializable {
String username
String password
}
String username
String password
}
5,“grails generate-all User”,生成所有与域类User相关的目录和文件,输出如下

6,将grails-app\controllers\UserController.groovy修改为如下内容
class UserController {
def index = { redirect(action:list,params:params) }
// the delete, save and update actions only accept POST requests
def allowedMethods = [delete: ' POST ' , save: ' POST ' , update: ' POST ' ]
def list = {
if ( ! params.max)params.max = 10
[ userList: User.list( params ) ]
}
def show = {
[ user : User.get( params.id ) ]
}
def delete = {
def user = User.get( params.id )
if (user) {
user.delete()
flash.message = " User ${params.id} deleted. "
redirect(action:list)
}
else {
flash.message = " User not found with id ${params.id} "
redirect(action:list)
}
}
def edit = {
def user = User.get( params.id )
if ( ! user) {
flash.message = " User not found with id ${params.id} "
redirect(action:list)
}
else {
return [ user : user ]
}
}
def update = {
def user = User.get( params.id )
if (user) {
user.properties = params
if (user.save()) {
flash.message = " User ${params.id} updated. "
redirect(action:show,id:user.id)
}
else {
render(view: ' edit ' ,model:[user:user])
}
}
else {
flash.message = " User not found with id ${params.id} "
redirect(action:edit,id:params.id)
}
}
def create = {
def user = new User()
user.properties = params
return [ ' user ' :user]
}
def save = {
def user = new User()
user.properties = params
if (user.save()) {
flash.message = " User ${user.id} created. "
redirect(action:show,id:user.id)
}
else {
render(view: ' create ' ,model:[user:user])
}
}
def loginSystemFlow = {
login {
on( " login " ) {
if ( " daniel " != params.username || " 123 " != params.password) {
flash.message = " username or password is invalid "
def user = new User()
user.properties = params
flash.user = user
return error ()
} else {
// 仅仅用来演示如何使用flow scope
flow.message = " Welcome, ${params.username} "
}
}.to " ok "
on( " register " ).to " showRegisterView "
}
ok()
showRegisterView()
}
}
7,在grails-app\views\user\目录下新建一个名为“ loginSystem”的子目录,该名称为UserController.groovy中的 loginSystemFlow的“loginSystem”相对应。
8,在grails-app\views\user\loginSystem\目录下新建 login.gsp, ok.gsp, showRegisterView.gsp三个GSP文件(这三个文件的文件名与
def loginSystemFlow = {
login {
...
}
ok()
showRegisterView()
}
中粗体突显的state名相对应,其中login为start state,而ok和showRegisterView为end state) ,并将其内容修改为:
login.gsp
< html >
< head >
< meta http-equiv ="Content-Type" content ="text/html; charset=UTF-8" />
< meta name ="layout" content ="main" />
< title > Login Page </ title >

</ td >
</ tr >
</ tbody >
</ table >
</ div >
< div class ="buttons" >
< span class ="button" >< g:submitButton class ="save"
name ="login" value ="Login" ></ g:submitButton >
</ span >
</ div >
< g:link action ="loginSystem" event ="register" > Register </ g:link >
</ g:form >

</ body >
</ html >
