At the same time, the corresponding SSH framework has attracted wide attention of academic field and the field of application development. This paper analyzed the technological superiority of the lightweight J2EE-based framework, introduced the structure and function of each framework in different layers and makes deeply researches on the features and role of Struts used in the persistent layer based on MVC design pattern, Spring used in the business layer and Hibernate used in the persistent layer. The paper discusses the SSH (Struts+Spring+Hibernate) multi-layers Web application integration framework and introduced the methods and the advantages of integration to achieve loose couples of layers and components and improve the reusability and maintains of the system.
