[Seasar-user:4746] S2ContinerのComponentの登録状況の表示について

2006年 10月 5日 (木) 06:59:48 JST

志村です。
S2ContainerもHotdeployと同じ設定で動く Cooldeployが提供されて、大変効率的
に開発出来る環境になりました。

依然 Sugaさんが、Blogに書かれていた S2servletでComponentの登録表示をする変更を
ほとんどそのままですが、Cooldeploy環境で使用すると大変便利でしたので報告します。

http://localhost:8080/test/s2servlet?command=componentのように入力すると

S2ContainerServlet is running.

ComponentDef: [homePage] com.shimura.page.HomePage
    extends    net.sf.click.Page
  autoBinding = auto
  instanceMode = request

  Aspect: [E-MAIL ADDRESS DELETED]
    interceptor: org.seasar.framework.aop.interceptors.TraceInterceptor
    pointcut: [E-MAIL ADDRESS DELETED]

ComponentDef: [newLogic] com.shimura.page.impl.NewLogicImpl
    implements com.shimura.page.NewLogic
  autoBinding = auto
  instanceMode = prototype

  Aspect: [E-MAIL ADDRESS DELETED]
    interceptor: org.seasar.framework.aop.interceptors.TraceInterceptor
    pointcut: null

ComponentDef: [test3Logic] com.shimura.test.logic.impl.Test3LogicImpl
    implements com.shimura.test.logic.Test3Logic
  autoBinding = auto
  instanceMode = prototype

  Aspect: [E-MAIL ADDRESS DELETED]
    interceptor: org.seasar.framework.aop.interceptors.TraceInterceptor
    pointcut: null

の様に表示されます。
