這次整理了先前大概wicket學習使用的簡單東西，創建了一個簡單登陸頁面。主要用來學習以下知識點內容。
wicket基礎配置文件等見上一篇文章：
頁面效果如下（用來測試控件學習使用的）

super(id, model);

}
@Override
protected void onSubmit() {
// form 提交後的處理
System.out.println(getModelObject().toString());
System.out.println(passwordField.getValue());
if(authenticate(usernameField.getValue(),passwordField.getValue())) {
MainPage mainPage = new MainPage(usernameField.getValue(),Login.this);
setResponsePage(mainPage);
}else {
//進入到失敗界面，或者登陸界面彈窗提示錯誤
System.out.println("輸入的用戶名或者密碼不對");

String errMsg = getLocalizer().getString("login.errors.invalidCredentials", this,"用戶名或者密碼不正確");

public final boolean authenticate (final String username,final String password) {
if(username.equals("zxr")&&password.equals("123456")) {
return true;
}else {
return false;
}
}
}
}
這裏主要是學習以下幾個內容：
1 wicket中頁面跳轉方式
1）直接使用類class
setResponsePage(MainPage.class);
2）這裏可以在類對象中設置變量值，實現傳遞參數
MainPage mainPage = new MainPage();
setResponsePage(mainPage);
2 wicket中樣式的引入，在頁面中要使用wicket:link
<wicket:linK>
<link rel="stylesheet" href="login.css" type="text/css"/>
</wicket:linK>
這裏給出GitHub的地址，不斷的學習後，不斷的去完善。
