Introduction
SSH: The new MVC software development model. SSH = Struts Spring Hibernate) which, Struts for process control, Spring for business transfer, Hibernate for database operations of the package, this new development model allows us to develop more convenient, fast, clear thinking! Hibernate is a persistence framework to deal with the database is a common, common database can be connected.
Spring is an open source framework to address the complexity of enterprise application development created. One of the main advantages of the framework is its layered architecture. Layered architecture allows you to choose which one component, as well as to provide an integrated J2EE application development framework.
Struts is a MVC-based framework for Sun J2EE platform. Servlet and JSP is mainly used technology to achieve. The struts can fully meet the needs of application development. Easy to use, quick fast, in the past year, the most attention. Struts the Servlet, JSP, custom tags and information resources (message resources) into a unified framework, developers do not use when developing their own code to achieve full re-MVC model, a great saving of time, so that the Struts is a very good framework.
Hibernate is a JDO tool. It works through the file to value objects and database tables to create a mapping between, so we only need to manipulate the value objects and Hibernate to provide some basic classes, we can achieve the purpose of using the database. For example, using Hibernate's query, can return a value object containing a list (List). Without having access to the same way as the traditional JDBC result set data to be loaded into a value-by-object, for our coding save a lot of work. Hibernate HQL is a class provided by the SQL language. EJBQL as it is to provide an object-oriented database query approach, but the function and use of HQL is very close to the standard SQL.
