Java Web框架 Aranea

Aranea 是一個 Java 的MVC 框架，提供一個通用簡單的方法來構建 Web 應用組件，以及可重用的業務邏輯和界面。

下面是一個登錄界面：

public class LoginWidget extends TemplateBaseWidget {
  /* Widget we will create and attach to this widget. */
  private FormWidget form;

  protected void init() throws Exception {
    /* Sets the view selector that will be used for rendering this widget. 
     * The path to real JSP file is determined by:
     *
     * StandardJspFilterService field jspPath (configured in aranea-conf.xml) 
     * + viewselector 
     * + ".jsp" */
    setViewSelector("login");

    /* Register a global proxying eventlistener - it receives all widget events and upon 
     * receiving event named "someEvent" proxies it to "handleEventSomeEvent" method 
     * 
     * This listener is added by default in super class and is only shown here for
     * illustrative purposes. It can also be cleared and overridden when needed.
     */   
     addGlobalEventListener(new ProxyEventListener(this));

    /* Create a new FormWidget with two self-described input fields. */
    form = new FormWidget();
    // Add the input fields. Arguments taken by addElement():  
    // String elementName, String labelId, Control control, Data data, boolean mandatory
    form.addElement("username", "#User", new TextControl(), new StringData(), false);
    form.addElement("password", "#Password", new TextControl(), new StringData(), false);

    // attach created form to our widget. 
    addWidget("loginForm", form);
  }

  // event handlers
}
