Bootstrap Job
一个play job任务就是一个在没有任何http请求的情况下执行一些特定的方法
应用程序在启动时或间隔一定时间后自动执行某个方法
应用程序启动便执行基础数据的初始化操作:
import models.User; import play.jobs.Job; import play.jobs.OnApplicationStart; import play.test.Fixtures; /** * 使用@OnApplicationStart注释Job,告诉Play在应用程序启动时便执行这个任务 * DEV模式和PROD模式下,任务执行情况不同 * DEV模式:等到第一个客户端请求才会执行 * PROD模式:应用程序启动时就执行 * @author lenovo * */ @OnApplicationStart public class Bootstrap extends Job { public void doJob() { //检查用户是否为空 if(User.count()==0) { Fixtures.loadModels("initial-data.yml"); } } }
其中,在yabe\conf目录下新建initial-data.yml文件,用来初始化Blog系统的基础数据!

It is the domain-specific representation of the information on which the application operates. Martin fowler defines it as : Responsible for representing concepts of the business, information about the business situation, and business rules. State that reflects the business situation is controlled and used here, even though the technical details of storing it are delegated to the infrastructure. This layer is the heart of business software. Post(secondBobPost): title: Just a test of YABE postedAt: 2009-03-25 author: bob content: > Well, it's just a test. Post(jeffPost): title: The MVC application postedAt: 2009-06-06 author: jeff content: > A Play! application follows the MVC architectural pattern as applied to the architecture of the Web. This pattern splits the application into separate layers: the Presentation layer and the Model layer. The Presentation layer is further split into a View and a Controller layer.

打开yabe\app\controllers\Application.java,修改index()
package controllers; import play.*; import play.mvc.*; import java.util.*; import models.*; public class Application extends Controller { public static void index() { //最新的博客 Post frontPost = Post.find("order by postedAt desc").first(); //过去的博客 List<Post> olderPosts = Post.find("order by postedAt desc").from(1).fetch(10); render(frontPost,olderPosts); } }
修改yabe\app\views\Application\index.html
action通过render()传递对象,在模块中只需要使用${xxx}就能获取到相应的对象,进而展现数据。
#{extends 'main.html' /} #{set title:'Home' /} #{if frontPost} <div class="post"> <h2 class="post-title"> <a href="#">${frontPost.title}</a> </h2> <div class="post-metadata"> <span class="post-author">by ${frontPost.author.fullname}</span> <span class="post-date">${frontPost.postedAt.format('MMMdd')}</span> <span class="post-comments"> | ${frontPost.comments.size() ?: 'no'} comment${frontPost.comments.size().pluralize()} #{if frontPost.comments} , latest by ${frontPost.comments[-1].author} #{/if} </span> </div> <div class="post-content"> ${frontPost.content.nl2br()} </div> </div> #{if olderPosts} <div class="older-posts"> <h3> Older posts <span class="from">from this blog</span> </h3> #{list items:olderPosts, as:'oldPost'} <div class="post"> <h2 class="post-title"> <a href="#">${oldPost.title}</a> </h2> <div class="post-metadata"> <span class="post-author">by ${oldPost.author.fullname}</span> <span class="post-date">${oldPost.postedAt.format('dd MMM yy')}</span> <div class="post-comments"> ${oldPost.comments.size() ?: 'no'} comment${oldPost.comments.size().pluralize()} #{if oldPost.comments} - latest by ${oldPost.comments[-1].author} #{/if} </div> </div> </div> #{/list} </div> #{/if} #{/if} #{else} <div class="empty"> There is currently nothing to read here! </div> #{/else}
抽取相同部分出来,提高代码复用性
新增yabe\app\views\tags\display.html
display.html被index.html使用标签(另一个模板)方式进行操作
由于index.html中通过#{display post:frontPost, as:'home' /}来调用display.html模板
则display.html中就可以通过_post 和 _as 来获取对应的参数值
#{extends 'main.html' /} #{set title:'Home' /} <div class="post ${_as == 'teaser' ? 'teaser' : ''}"> <h2> <a href="#">${_post.title}</a> </h2> <div class="post-metadata"> <span class="post-author">by ${_post.author.fullname}</span> <span class="post-date">${_post.postedAt.format('dd MMM yy')}</span> #{if _as!='full'} <span class="post-comments"> | ${_post.comments.size() ?: 'no'} comment${_post.comments.size().pluralize()} #{if _post.comments} , latest by ${_post.comments[-1].author} #{/if} </span> #{/if} </div> #{if _as!='teaser'} <div class="post-content"> <div class="about">Detail:</div> ${_post.content.nl2br()} </div> #{/if} </div> #{if _as=='full'} <div class="comments"> <h3> ${_post.comments.size() ?: 'no'} comment${_post.comments.size().pluralize()} </h3> #{list items:_post.comments, as:'comment'} <div class="comment"> <div class="comment-metadata"> <span class="comment-author">by ${comment.author},</span> <span class="comment-data">${comment.postedAt.format('dd MMM yy')}</span> </div> <div class="comment-content"> <div class="about">Detail: </div> ${comment.content.escape().nl2br()} </div> </div> #{/list} </div> #{/if}
修改index.html,直接通过display模板完成页面的显示
#{extends 'main.html' /} #{set title:'Home' /} #{if frontPost} <!--调用display模板--> #{display post:frontPost, as:'home' /} #{if olderPosts.size()} <div class="older-posts"> <h3> Older posts <span class="form">from this blog</span> </h3> #{list items:olderPosts ,as:'oldPost'} <!--调用display模板--> #{display post:oldPost, as:'teaser' /} #{/list} </div> #{/if} #{/if} #{else} <div class="empty"> There is currently nothing to read here! </div> #{/else}
刷新页面
修改yabe\public\stylesheets\main.css,对页面进行美观修饰
附:main.css
