Extjs + DWR + spring + hibernate development HRMS (1)

Nowadays, ssh combinations are widely used in Java EE applications, and Ajax technologies are everywhere. We generally use struts compliant with the MVC design pattern to regulateProgramStructure, use the excellent ORM Component hibernate to simplify database access operations, use the system adhesive spring to improve development efficiency, and use Ajax for asynchronous access to improve user experience. Today, a demo is a simplified HRMS (Human Resource Management System). On SSH, spring has its own MVC Framework implementation, so we use it to replace struts, on Ajax, we use two framework components: extjs and DWR. The former can provide very dazzling page effects, and the latter can easily access the Java Server.Code.

 

Because there are many technologies involved, I cannot elaborate on them one by one. If you do not know much about the relevant knowledge, you can first take a look at their introduction and basic usage methods. Well, let's take a look at our page effects:

2. on the home page of the employee management module-edit employee information:

 

3. on the home page of the employee management module-delete an employee:
