grails 中render xml json 使用記錄

asdtiang — Mon, 10 Jan 2011 04:24:00 GMT

只有使用了，才知道方便和強大啊，這主要還是依賴于groovy的MarkupBuilder，詳見：http://groovy.codehaus.org/Creating+XML+using+Groovy%27s+MarkupBuilder
只有理解了它，在grials里使用render xml才能如魚得水啊。其實很簡單

def xml = new MarkupBuilder(writer)
xml.records() {
car(name:'HSV Maloo', make:'Holden', year:2006) {
    country('Australia')
    record(type:'speed', 'Production Pickup Truck with speed of 271kph')
}
}
對應的xml文檔：


        Australia
        Production Pickup Truck with speed of 271kph


只要分清對應關系就可以了。屬性和屬性值，節點，節點的值怎么畫到groovy里。
下面是controller里的返回xml代碼：
def tests=TestAjaxPage.findAll()
  render(contentType:"text/xml") {
   tests1 {
    for(b in tests) {
     test(title:b.title,dateCreated:b.dateCreated){
      h b.content
      }
    }
   }
  }

對應的返回文檔為：

haha

這其實對于b/s,再混用c/s的程序中交換數據還是很有用的，so easy

render json就要麻煩點了，主要是1.1版本和1.3.6版本寫法不一樣：
先寫1.1的吧：
render(contentType:"text/json") {
     max "max"
     resultList{
      Book.getAll().each{oneitem->
            Book(
         id:oneitem.id,
         name:oneitem.name,
         )
      }
     }
    }
1.3.6的寫法如下：
def tests=TestAjaxPage.findAll()
  render(contentType:"text/json") {
   max (max1:"max")
   tests1= array{
    tests.each {one->
        TestAjaxPage(
       id:one.id,
       content:one.content,
       title:one.title,
       dateCreated:one.dateCreated
       )
    }
   }
  }
返回數據：{"max":{"max1":"max"},"tests1":[{"id":1,"content":"qewrqwe","title":"qwereqwr","dateCreated":"2011-01-07T10:11:52Z"}]}
最后var e=originalRequest.responseText.evalJSON();就是在js里調用下.evalJSON()，就可以看做對象訪問數據。

版本不同，我手里一致用1.1的中文文檔，做的時候自己用的1.3.6，郁悶了好久，出不來。最后看1.3.6的文檔才發現寫法不一樣呢

grails acegi 在線用戶統計

asdtiang — Mon, 10 Jan 2011 04:03:00 GMT

主要參考文檔：http://grails.1312388.n4.nabble.com/Information-about-all-logged-in-users-with-Acegi-or-SpringSecurity-in-Grails-td1372911.html

根據文檔，基本操作翻譯如下：（注意只統計在線用戶，也就是登錄的用戶）

在SecurityConfig中設置 useHttpSessionEventPublisher 為true,
// HttpSessionEventPublisher
useHttpSessionEventPublisher = true
這樣不用更改web.xml文件

resources.groovy:文件增加以下bean：
   beans = {

sessionRegistry(org.springframework.security.concurrent.SessionRegistryImpl)

sessionController(org.springframework.security.concurrent.ConcurrentSessionControllerImpl) {
maximumSessions = -1 //表示同一個賬戶可以多次登錄，但只計一個在線用戶
         sessionRegistry = ref('sessionRegistry')
}
}

BootStap對應增加以下內容：
class BootStrap {

def authenticationManager
def sessionController

def init = { servletContext ->
authenticationManager.sessionController = sessionController
}
      def destroy = {}
}

測試

class OnlineController {
def sessionRegistry
def test={
render sessionRegistry.getAllPrincipals().length
}

}
主要類的文檔：
ConcurrentSessionControllerImpl：
http://static.springsource.org/spring-security/site/docs/2.0.x/apidocs/org/springframework/security/concurrent/ConcurrentSessionControllerImpl.html
SessionRegistryImpl：
http://static.springsource.org/spring-security/site/docs/2.0.x/apidocs/org/springframework/security/concurrent/SessionRegistryImpl.html

grails acegi ajax登錄

asdtiang — Fri, 07 Jan 2011 06:47:00 GMT

js代碼如下：

login代碼示例：

def ajaxSuccess = {
        nocache(response)
        def config = authenticateService.securityConfig.security
        def postUrl = "${request.contextPath}${config.defaultTargetUrl}"
        render "{success: true,url:'${postUrl}'}"http://這里返回的是json
    }

def authfail = {

        def username = session[AuthenticationProcessingFilter.SPRING_SECURITY_LAST_USERNAME_KEY]
        def msg = ''
        def exception = session[AbstractProcessingFilter.SPRING_SECURITY_LAST_EXCEPTION_KEY]
        if (exception) {
            if (exception instanceof DisabledException) {
                msg = "[$username] 用戶被禁用."
            }
            else {
                msg = "[$username] 錯誤的用戶名或密碼."
            }
        }

        if (isAjax()) {
            render "{error: '${msg}'}"
        }
        else {
            flash.message = msg
            redirect action: auth, params: params
        }
    }

頁面：

<form action='${request.contextPath}/j_spring_security_check'

method='POST' id='ajaxLoginForm' name='ajaxLoginForm' target="_blank">

用戶名<input id="j_username" name="j_username" type="text" />

密碼<input name="j_password" id="j_password" type="password" /><input onclick='authAjax(); return false;'type="image" src="login.jpg" />

form>

暫時想不起來為什么用兩個form呢，最后引入js:

grails searchable highlight顯示查詢結果

asdtiang — Wed, 22 Dec 2010 09:46:00 GMT

查不到中文的結果，所以這里記一下
以前用lucene時，還比較好控制，用searchable還不太適應。

def index = {
        if (!params.q?.trim()) {
            return [:]
        }
        try {
            params.withHighlighter= songHighlighter
            return [searchResult: searchableService.search(params.q, params)]
        } catch (SearchEngineQueryParseException ex) {
            return [parseException: true]
        }
    }
  // This closure does the per-hit highlighting
// sr is the actual Map returned by search, so use that for storage
   def songHighlighter = { highlighter, index, sr ->
    // lazy-init the storage
    if (!sr.highlights) {
        sr.highlights = []
    }
    //content為domain的屬性
    sr.highlights[index] = highlighter.fragment("content")
   }// Do the search, passing he highlighter option

頁面更改：

<g:each var="result" in="${searchResult.results}" status="index">
          <div class="result">
            <g:set var="className" value="${ClassUtils.getShortName(result.getClass())}" />
            <g:set var="link" value="${createLink(controller: className[0].toLowerCase() + className[1..-1], action: 'show', id: result.id)}" />
            <div class="name"><a href="${link}">${result.title}a>div>

            <div class="desc">${searchResult.highlights[index]}div>
            <div class="displayLink">${link}div>
          div>
        g:each>

查詢結果示例，直接輸出的searchResults

{total=3, hits=org.compass.core.impl.DefaultCompassDetachedHits@4eb331, max=10, scores=[0.34462962, 0.34462962, 0.19071755], results=[asdf, asdf, 中國（拼音：Zhōngguó），是中華人民共和國的簡稱。古代華夏族建國于黃河流域一帶，以為居天下之中，故稱。還有一種解釋古代中國人認為天圓地方，中國位于正中，故稱中國，后成為專稱。清朝，作為官方正式稱呼，現代主要指中華人民共和國（英譯為：The People's Republic of China，簡稱China）。陸地面積960萬平方千米，東部和南部大陸海岸線1.8萬多千米，內海和邊海的水域面積約470多萬平方千米。海域分布有大小島嶼7600個。首都北京。中國具有五千年的文明史，是世界四大文明古國之一。因其文化傳播的廣泛性、獨特性和成熟性而對周邊國家和民族的文化產生深遠影響，同時不斷吸收各個民族的文明成果，是世界上少數最早產生文明并延續至今的國家之一。 ], offset=0, highlights=[null, null, 中國（拼音：Zhōngguó），是中華人民共和國的簡稱。古代華夏族建國于黃河流域一帶，以為居天下之中，故稱。還有一種解釋古代中國人認為天圓地方，中國位于正中，故稱中國，后成為專稱。清朝，作為官方正式]}

查詢結果高亮顯示css為b,
只要在css里加上b{color : red;}，就顯示為紅色了。

從結果可以看出，要了highlights就沒有必要要results,信息重復，但each里用了，要下班了，明天研究下吧

剛到公司，想起來了，當時在domain類下重寫了toString()方法，不重寫results里就沒有那么多內容了。

grails fckeditor上傳圖片顯示不了的問題

asdtiang — Wed, 11 Aug 2010 04:06:00 GMT

fckeditor插件的安裝就不用多說了，在使用時有時會出現上傳圖片顯示的情況，
config配置如下：

appName='tatu'///為項目的名稱
//?set?per-environment?serverURL?stem?for?creating?absolute?links

????????grails.serverURL?=?"http://www.changeme.com"
????}
????development?{
????????grails.serverURL?=?"http://localhost:8080/${appName}"
????}
????test?{
????????grails.serverURL?=?"http://localhost:8080/${appName}"
????}

}

fckeditor?{

????}

有時會遇到上傳了，顯示不了，查看一下上傳文件沒有在項目文件夾下面，這里可以改源碼：
找到FckeditorController的execute方法

????????def?type?=?params.Type
????????def?currentPath?=?"${baseDir}${spaceDir}${type}${currentFolder}"
????????def?currentUrl

grails 實現級聯下拉列表

asdtiang — Tue, 10 Aug 2010 03:22:00 GMT

不多說，可以實現多級，http://xihuyu2000.javaeye.com/blog/349722，這個地方可以實現兩級，但我這里可以實現多級，直接上代碼吧。

說明，手機充值有服務商，面值，和區域，現在數據庫設計有點問題，不過能說明問題就行。

class TelDeltaPro {
    String id
    String name//服務商
    String area//區域
    String price//面值
    String goodId
    int sum//沖值總次數
    static mapping={
        id generator:'uuid'
    }
}

頁面主要代碼：

<tr>
            <td><span class="indexText2">服務商span>td>
            <td><g:select name="proName"
                from="${com.likai.asdtiang.domain.platform.TelDeltaPro.list()}"
                optionKey="name" optionValue="name"
                onchange="${remoteFunction(controller:'telDeltaPro', action:'price', params:'\'name=\'+this.value', update:[success:'price'])}">g:select>
            td>
        tr>
        <tr>
            <td><span class="indexText2">面值span>td>
            <td>
            <div id="price">div>

            td>
        tr>
        <tr>
            <td><span class="indexText2">地區span>td>
            <td>
            <div id="area">div>
            td>
        tr>
        <tr>
            <td>td>
            <td><input type="submit" value="提交">td>
        tr>

主要是onchange="${remoteFunction(controller:'telDeltaPro', action:'price', params:'\'name=\'+this.value', update:[success:'price'])}"這個地方，remoteFunction查下文檔就可以了。

contorller主要代碼如下：

def price={
        log.info params.name+"name"
        session.putValue "telName",params.name
        def str=""""proName" name="price" onchange="${remoteFunction(controller:'telDeltaPro',
         action:'area', params:'\'price=\'+this.value', update:[success:'area'])}">"""
        def li=TelDeltaPro.findAllByName(session.telName)
        li.each{
            str=str+""""${it.price}">${it.price}"""
        }
        str=str+""""""
        render(text:str,contentType:"text/html",encoding:"UTF-8")
    }
    def area={
        log.info params.price+"    price"
        def str=""""area" >"""
        def li=TelDeltaPro.findAllWhere(name:session.telName, price:params.price)
        li.each{
            str=str+""""${it.area}">${it.area}"""
        }
        str=str+""""""
        render(text:str,contentType:"text/html",encoding:"UTF-8")

    }

代碼應該很簡單的，看下就懂了。
最后應該注意下：導入AJAX腳本，因為remoteFunction用到了AJAX

"prototype" />

grails acegi使用----注冊時發送email

asdtiang — Tue, 20 Apr 2010 10:29:00 GMT

在這里記一下，注冊時發送出email就行了，至于如果運行配置和運行acegi在官網上就能查到。
    useMail = true
   mailHost = "smtp.sina.com"
   mailUsername = "xxxxxxx"
   mailPassword = "xxxxxxx"
   mailProtocol = "smtp"
   mailFrom = "xxxxxxx@sina.com"
   mailPort = 25
   javaMailProperties=["mail.smtp.auth":"true","mail.smtp.socketFactory.fallback":"false"]
   defaultRole="user"
   defaultTargetUrl = "/login/main.gsp"

其中javaMailProperties=["mail.smtp.auth":"true","mail.smtp.socketFactory.fallback":"false"]是關鍵，spring的email默認不進行認證的，如果只加"mail.smtp.auth":"true",也不行，問了下網友，加上后面的屬性就行了。
在這里也學習到grails的service歸約規則：
8. The Service Layer

Grails服務的一個重要方面是，有能力利用Spring 框架的依賴注入能力。 Grails支持 "依賴注入通過規約". 換句話說，你可以使用一個屬性名表示的一個服務的類名，自動把他們注入到 controllers, tag libraries,等等。

作為示例，給定的服務名為BookService, 如果你像下面這樣在controller中放置一個名為bookService 的屬性:

class BookController {
def bookService
…
}

在這種情況下，Spring 容器將自動注入一個基于它自己配置作用域的服務實體。所有的依賴注入是通過名字的; Grails 不支持類型注入。你也可以像下面這樣指定類型:

class AuthorService {
BookService bookService
}

不過, 存在副作用，即在開發模式下BookService的改變會在加載時拋出一個錯誤。

依賴注入與服務

你可以使用相同的技術在一個服務中注入另一個服務。如果說，你的AuthorService需要一個 BookService, 可以像下面這樣聲明 AuthorService:

class AuthorService {
def bookService
}

依賴注入與Domain類

你甚至可以在domain類中注入服務，這可以幫助開發出各種豐富的domain:

class Book {
…
def bookService
def buyBook() {
bookService.buyBook(this)
}
}

gsp學習筆記pageinate

asdtiang — Sat, 27 Feb 2010 03:36:00 GMT

Grails Reference

paginate

用途

創建下一個/上一個按鈕和一個 breadcrumb 實現分頁.

示例

domain class實例:

class Book {
     String title
     String author
}

controller實例:

class BookController {
  def list = {
     [books: Book.list(params)]
  }
}

標簽頁代碼:

						"book" action="list" total="${Book.count()}" />

或

						"Forward" prev="Back"
            maxsteps="0" controller="book"
            action="list" total="${Book.count()}" />

描述

屬性

total (必需) - 頁數的總數量.
action (可選) - 要鏈接的action名稱,如果不指定,鏈接到當前action.
controller (可選) - 要鏈接的controller名稱,如果不指定,鏈接到當前的controller.
id (可選) - link的id
params (可選) - 包含請求參數的 map.
prev (可選) - 顯示上一頁 (根據默認值定義 "Previous" 做為默認的分頁)
next (可選) - 顯示下一頁
max (可選) - 每頁顯示的總記錄 (默認為 10條記錄).
maxsteps (可選) - 分頁的數量.
offset (可選) - 僅用于 params.offset 為空.

gsp學習筆記each select set

asdtiang — Wed, 24 Feb 2010 02:37:00 GMT

gsp中的select標簽使用：

<g:select?name="category.id"?from="${org.asdtiang.study.grails.Category.list()}"
??????????????????????????????????????????????optionKey="id"?optionValue="categoryName"
?value="${goodsInstance?.category?.categoryName}"??/>

from指定數據來源。
optionKey="id"表示依次用數據源中每個Category的id作為每個選項的值（即中test對應內容）
value指定當前列表中與value等值的選項。

application - The javax.servlet.ServletContext instance
applicationContext The Spring ApplicationContext instance
flash - The flash object
grailsApplication - The GrailsApplication instance
out - The response writer for writing to the output stream
params - The params object for retrieving request parameters
request - The HttpServletRequest instance
response - The HttpServletResponse instance
session - The HttpSession instance
webRequest - The GrailsWebRequest instance

1?<html>
2???<body>
3?????Hello?${params.name}
4???body>
5?html>
6?

GSP also supports logical and iterative tags out of the box. For logic there are if, else and elseif which support your typical branching scenarios:

1?<g:if?test="${session.role?==?'admin'}">
2????<%--?show?administrative?functions?--%>
3?g:if>
4?<g:else>
5????<%--?show?basic?functions?--%>
6?g:else>
7?
8?

For iteration GSP has the each and while tags:

?1?<g:each?in="${[1,2,3]}"?var="num">
?2????<p>Number?${num}p>
?3?g:each>
<g:each?in="${goodsInstanceList}"?status="i"?var="goodsInstance">
<%-- in指定遍歷的集合，status指定索引，var指定每次取出元素的名稱，默認為it --%>
??????????????????????? <tr?class="${(i?%?2)?==?0???'odd'?:?'even'}">
????????????????????????
????????????????????????????<td><g:link?action="show"?id="${goodsInstance.id}">${fieldValue(bean:?goodsInstance,?field:?"id")}g:link>td>
????????????????????????
????????????????????????????<td>${fieldValue(bean:?goodsInstance,?field:?"title")}td>??????????????????????? 
<%--fieldValue方法的作用是取出指定bean的指定屬性，能自動執行encodeAsHtml()操作，以防止跨站腳本攻擊--%>
????????????????????????????<td><img?alt="不能顯示"?src="${fieldValue(bean:?goodsInstance,?field:?"photoUrl")}"?style="width:300px;?height:300px"?>td>
????????????????????????
????????????????????????????<td>${goodsInstance.category?.categoryName}td>

????????????????????????
????????????????????????tr>
??g:each>

?4?
?5?<g:set?var="num"?value="${1}"?/>
?6?<g:while?test="${num?>
?7?<p>Number?${num++}p>
?8?g:while>
?9?
