javaeetutorial6 學習筆記 -the web tier

    真是不多寫博客,做爲一我的軟件人真是失敗,以爲本身的知識面實在是太窄了,決定學習,而後記錄下重點。html

    我的認爲何書都不如官方提供的tutorial,今天突發奇想看看javaee,我一直都相信基礎牢固學什麼都快,框架更不用說了,沒有結實的基礎你學架構只能說是會用吧。廢話很少說了。java

    web application 剛開始看我就又有了深入的理解了。。。。以前只是硬編碼,回想起來那時候真是。。。。接下來的這段話應該把javaee技術都歸納進來了.web

    In the Java EE platform, web componentsprovide the dynamic extension capabilities for a web server. Web components can be Java servlets, web pages implemented with JavaServer Faces technology, web service endpoints, or JSP pages.Figure 3–1illustrates the interaction between a web client and a web application that uses a servlet. The client sends an HTTP request to the web server. A web server that implements Java Servlet and JavaServer Pages technology converts the request into an HTTPServletRequest object. This object is delivered to a web component, which can interact with JavaBeans components or a database to generate dynamic content. The web component can then generate an HTTPServletResponseor can pass the request to another web component. A web component eventually generates a HTTPServletResponseobject. The web server converts this object to an HTTP response and returns it to the client.架構

     我的以爲理解了這段內容,你對javaee總體應該有所瞭解了。框架

    個人英文也很差  ,沒辦法  ,只有學。還有一點我想說,千萬不要以爲本身不行,我問過不少人,也是從被人教育的階段過來的,一點要記住,就是鍥而不捨,第一遍看不懂就看第二遍第三遍,直到懂,若是你這樣堅持下去,那麼你絕對是高手。ide
