What is Struts2?




Struts2 is a framework that simplifies the development of Java web applications. It is based on the Model-View-Controller (MVC) design pattern, which separates the business logic, the presentation layer, and the user interaction. Struts2 provides a set of components and tools that help developers create dynamic, interactive, and user-friendly web pages.


A brief history of Struts2




Struts2 was created in 2006 as a successor to Struts1, which was one of the first and most widely used Java web frameworks. Struts1 was developed by Craig McClanahan in 2000 and donated to the Apache Software Foundation in 2001. However, over time, Struts1 became outdated and difficult to maintain. It had several limitations and drawbacks, such as:


  • It was tightly coupled with servlets and JSPs, which made it hard to test and reuse code.



  • It used a single controller servlet that handled all requests, which created performance issues and scalability problems.



  • It relied on XML configuration files that were verbose and error-prone.



  • It did not support annotations, generics, or other modern Java features.



Struts2 was designed to overcome these limitations and provide a more flexible, powerful, and easy-to-use framework. It was originally developed by WebWork, another Java web framework that was similar to Struts1 but more advanced. WebWork merged with Struts1 in 2005 and became Struts2 in 2006. Some of the main improvements and advantages of Struts2 over Struts1 are:


  • It is loosely coupled with servlets and JSPs, which allows developers to use other technologies such as Freemarker, Velocity, or Tiles for the view layer.



  • It uses multiple interceptors that can be applied to different actions or requests, which improves performance and modularity.



  • It supports annotations, generics, dependency injection, and other modern Java features that make coding easier and more expressive.



  • It uses OGNL (Object-Graph Navigation Language), a powerful expression language that can access and manipulate any object in the application.



The main features of Struts2




Struts2 offers a rich set of features that help developers create web applications faster and better. Some of the main features of Struts2 are:


  • Actions: Actions are the core components of Struts2 that handle the requests from the users and perform the business logic. Actions can be simple Java classes or POJOs (Plain Old Java Objects) that implement the Action interface or extend the ActionSupport class. Actions can also have properties, methods, and annotations that define their behavior and configuration.



  • Interceptors: Interceptors are components that intercept the requests before and after they reach the actions. Interceptors can perform various tasks such as validation, logging, authentication, or encryption. Interceptors can be configured globally or locally, and can be stacked together to form interceptor stacks.



  • Results: Results are components that determine what happens after an action is executed. Results can be different types such as JSPs, redirects, JSON, or custom results. Results can also have parameters that specify their attributes and options.



  • Validators: Validators are components that validate the input data from the users and display error messages if the data is invalid. Validators can be defined in XML files, annotations, or programmatically. Validators can also be grouped together to form validator groups.



  • Internationalization: Internationalization is the process of making an application support multiple languages and locales. Struts2 supports internationalization by using resource bundles, which are files that contain key-value pairs of messages in different languages. Struts2 also provides tags and utilities that help developers display and format messages according to the user's locale.



  • Struts2 Plugins: Struts2 plugins are modules that extend the functionality of Struts2 by providing additional features or integrations with other frameworks or technologies. For example, there are plugins for AJAX, Spring, Hibernate, REST, JUnit, and more. Struts2 plugins can be easily installed by adding them to the classpath of the application.



The benefits of using Struts2




Using Struts2 has many benefits for developers and users alike. Some of the benefits of using Struts2 are:


  • It is easy to learn and use: Struts2 has a simple and consistent architecture that follows the MVC pattern and the convention over configuration principle. It also has a clear and comprehensive documentation that explains how to use Struts2 effectively.



  • It is flexible and customizable: Struts2 allows developers to choose their own technologies and tools for the view layer, the persistence layer, or the testing framework. It also allows developers to create their own components or plugins to suit their specific needs.



  • It is powerful and expressive: Struts2 supports many advanced features and concepts such as annotations, generics, dependency injection, OGNL, interceptors, validators, results, plugins, and more. These features make coding easier and more expressive, while also improving performance and functionality.



  • It is compatible and scalable: Struts2 is compatible with any Java web container or application server that supports servlets 2.4 or higher. It also supports various web standards and protocols such as HTTP, HTTPS, REST, JSON, XML, etc. It also supports clustering and load balancing for high availability and scalability.
