　Easyjweb [Java open source web development framework]

Easyjweb is an MVC framework that is based on Java technology and applied to the rapid development of Web applications. The framework design concept comes from many domestic project practices, the framework fully signs the popular open-source Web frameworks (struts, JSF, tapestry, and webwork), draws on its advantages and essence, and uses velocity as the template page engine, is an MVC development framework that completely isolates pages and code. Is a simple Web framework that can quickly develop small and medium-sized web application systems.

With the supporting development tools provided by easyjwebtools, you can quickly develop web applications based on the easyjweb framework, including code generation of common application software, database addition, deletion, and modification (crud) code Generation, automatic page template generation, and configuration file management.

　Framework features:◆ Zero-configuration file configuration is supported. In the past, every time we came into contact with a framework, we always had to be overwhelmed by its configuration file. Easyjweb supports Zero Configuration. You can build your application on the basis of the framework without writing a configuration file. (Suitable for small website systems ).

◆ Simple template page design support: discard JSP and use simple velocity script language as the page template.

◆ Completely separated page programs: the display page and program logic are completely separated, which overcomes the difficulty of maintaining traditional JSP pages.

◆ Page component-based framework. Flexible page component configuration, you can directly set field-level event components through the configuration file.

◆ Quick development support: With easyjwebtools, You can automatically generate application software template code, customize and manage your own J2EE code template, code Generation templates support the most popular practical Java development frameworks (such as Hibernate and spring) for rapid development.
