Starting With Apache Wicket (Version 9.X+)

欢迎来到“从 Apache Wicket 开始”课程。通过本课程，您将通过熟悉解决特定选择的 JAVA Web 应用程序开发领域的几种技术，为您现有的 JAVA 和 Apache Wicket 9+（带有 SpringBoot）知识增加价值。

我们将重点关注在企业 JAVA 开发中通常有用的几个主题，但不限于此。SpringBoot 在这里用作底层框架，但这里介绍的解决方案并不特定于该平台，并且可以重用，例如最近的 Quarkus 支持等。

本课程的主要思想是帮助新的或现有的 Apache Wicket 开发人员以简单的方式采用某些知识。所提出的解决方案已在生产级 Wicket 应用程序中使用了数年，所使用的库以稳定性和积极开发而闻名。这将保护投资于采用某些库或项目的价值。

本课程涵盖的主题：
在课程中，我们创建了基本的 Apache Wicket 单页应用程序，每次讲座都会为其添加新的增强功能。最终，我们创建了具有许多不同功能的单个应用程序。主要议题包括：

• 使用 Apache Wicket 创建功能齐全的单页应用程序
• 以 MS Excel 格式导出应用程序数据，并具有格式化和其他一些功能
• 以带有格式、嵌入图像或条形码的 PDF 格式导出应用程序数据
• 包括 MongoDB 作为持久数据存储
• 使用 GridFS 作为附件/文件上传数据存储（准备中）

本课程的重要部分是了解使用 Apache Wicket 时“我们不需要做什么”。简化可能是巨大的，古老的说法“最好的代码是你不必编写的代码”在这里得到了证明。

重要的：

源代码可通过本课程最后一课所附的链接获得。您可以克隆存储库并使用我们在本课程中构建的代码片段。

Description

Hello,

welcome to the ‘Starting with Apache Wicket’ course. With this course you are going to add a value to your existing JAVA and Apache Wicket 9+ (with SpringBoot) knowledge by getting familiar with several techniques for solving specifically selected areas of JAVA web application development.

We will focus on several topics often useful in corporate JAVA development but not exclusively. SpringBoot is being used here as an underlying framework, but solutions presented here are not specific to this platform and can be reused e.g. with recent Quarkus support etc.

Primary idea of this course is to help a new or existing Apache Wicket developers to adopt certain knowledge in easy way. Solutions presented are being used for several years in production grade Wicket applications and libraries used are well known for stability and active development. This will protect the value invested into adopting some libraries or projects.

Topics covered by this course:
During a course we create basic Apache Wicket single page application and each lecture will add a new enhancement to it. Eventually we create single application with many different features. Main topics include:

• creating a full featured single page application using Apache Wicket
• export application data in MS Excel format with formatting and some other features
• export application data in PDF format with formatting, embedded images or bar-codes
• including MongoDB as persistent data storage
• using GridFS as an attachment/file uploads data storage (PREPARING)

Important part of this course is to realize ‘what we don’t need to do’ when using Apache Wicket. Simplification can be huge and old saying that ‘the best code is the code you don’t have to write’ proves here.

Important:

The source code is available through the link attached to the last lesson in this course. You can clone the repo and use the code snippets we are building in this course.

Summary:

‘Starting with Apache Wicket’ course is targeted for individuals or small/medium teams of professional Java developers that want to be productive and competitive in this large market. Techniques presented here can be reused easily in application development of many kinds.
