Struts2 is a popular and mature web application framework based on MVC design patterns, and it is not only an upgraded version of Struts1, but also a brand new Struts architecture. /b10> Initially, the Goal of simplifying the development of web technicians was achieved by providing an enhanced and improved Struts framework based on the WebWork framework and the Struts framework. /b12> Soon after, the Webwork framework and the Struts community teamed up to create the now-popular Struts2 framework.

Benefits of the Struts2 framework

Understanding these key benefits will prompt you to consider Struts2:
  • POJO Forms and POJO Actions - Struts2 removes the Action Forms section of the Struts framework. Under the Struts2 framework, you can receive form input with any POJO, and you can think of any POJO as an Action class.
  • Label support - Struts2 improves label forms, while new tags allow developers to write less code.
  • AJAX Support - Struts2 is recognized for receiving Web 2.0 technology and has created AJAX tags that are very similar to the standard Struts2 tag, integrating AJAX support into its results.
  • Easy to integrate - Struts can be used in a variety of ways, and it's now easier to integrate with other types of frameworks, such as Spring, Tiles, SiteMesh, and more.
  • Template support - Supports the use of templates to generate views.
  • Plug-in support - There are a number of plug-ins available for Struts2, while using plug-ins enhances and expands Struts2 core behavior.
  • Performance Analysis - Struts2 provides comprehensive performance analysis for debugging and configuration applications, and Struts also provides integrated debugging in the form of embedded debugging tools.
  • Easy to modify labels - In Struts2, tag tags can be adjusted using Freemarker's template, and modifying tags does not require JSP or Java knowledge, basic HTML, XML, and CSS knowledge is sufficient.
  • Promotes reduced configuration - Struts2 uses default values for various settings to facilitate reduced configuration, and you don't need to configure anything unless you deviate from the default settings set by Struts2.
  • View Technology - Struts2 supports a variety of view options (JSP, Freemarker, Velocity, XSLT, etc.).
These are the top ten advantages of making Struts2 a quasi-enterprise framework.

The disadvantages of the Struts2 framework

Although Struts2 has the advantages of a large column, we would like to mention some of the disadvantages about it that still need to be improved:
  • Larger learning curve - With Struts MVC, you have to be familiar with JSP, Servlet APIs, and a large, complex framework.
  • Lack of documentation - Struts has fewer online resources than the Servlet and JSP APIs standards, and many beginners will find Apache online documents confusing and unstided.
  • Not transparent enough - Many applications that use Struts are performed in the background compared to normal Java-based Web applications, which makes the framework less easy to understand.
Finally, a good framework should provide common behaviors that can be used by all types of applications, and Struts2 is one of the best Web frameworks and is frequently used for the development of RIA (Rich Internet Applications).
