The @controller, @RestController, @RequestMapping annotations we used before. If you are unfamiliar with spring MVC and have not tried a QuickStart case, it is advisable to look at the SPRINGMVC annotation first; @Controller: Modifier class, which is used to create an object that handles HTTP requests @RestController: Annotations added after Spring4, the original return of JSON in @controller requires @responsebody to match, If you replace @controller directly with @restcontroller, you do not ne

Introduction to Apache POI Apache POI is a set of Java APIs for accessing Microsoft Office format documents (Word, Excel, and PowerPoint). The API used to manipulate Excel format files is HSSF, and the API for manipulating Word format files is HWPF and the API for manipulating PowerPoint format files is HSLF. POI's official website is http://poi.apache.org, the user can download the latest version 3.6 from here first, download after decompression ha

vulnerable connections (that is, passwords) for authentication systems. The industry is in great need of technology that can replace passwords. With embedded cryptographic processors, smart cards provide a very secure and easy-to-use authentication mechanism. However, the deployment of smart cards also poses a unique challenge. The entire industry needs better products to deploy and manage complex authentication technologies. In his keynote address at the RSA 2006 Conference, Bill Gates demons

bind the code to a specific Xalan API.Although JDOM has not implemented JAXP, JDOM is still very popular because of its simplicity and has become an API officially recommended by JCP. It is also a tree structure of XML, which is much easier to use than the w3c dom standard. The latest version of JDOM has started to use JAXP APIs internally. It will try its best to call JAXP

The FileSystem API (file system API) simulates a local file system that a network application can navigate to. You can develop applications to read, write, create, and index files in a sandbox virtual file system.The file system API interacts with other related APIs. It is based on the file write API (the files writer API), and the latter is based on the file API (FileName API). Each API has a different function. These

The Android mobile phone operating system has been well received by users. In particular, its open-source features have greatly attracted the favor of developers. Android is applicable to various types of mobile phones, from the lowest end to the highest end. The core Android API can be used on every mobile phone, but some APIs have some special applicability: this is the so-called Android optional API. Android sharing feature source code Android C

Mathieu fenniak, author of the original article, shouted in his blog: Do not design fragile Web APIs. Otherwise, your partners or third-party developers will hate you and leave you alone. He believes that the key to designing a relatively stable and strong API is to focus on the purpose of the application. The article also shares some precautions for designing excellent APIs. Let's take a look at the follow
