基于SSH的企業(yè)人力資源信息化系統(tǒng)研究
[Abstract]:With the increasingly fierce competition in the market, enterprises must carry on information construction and improve productivity. Making use of computer software and hardware technology and network technology, the establishment of networked, electronic and information-based human resource system is one of the important construction links. In this paper, we design and implement an enterprise human resource information system using the mature Struts,Spring and Hibernate application framework. The system is close to the business requirements of the enterprise and adopts a hierarchical design method, which enables the system to improve the flexibility and robustness of the program as far as possible under the premise of satisfying the needs of the users. Starting with the background and research significance of the project, this paper proves the social value and technical value of the choice of the subject. Then the related technology of the project is described. Application framework is the core technology in this paper. Starting from the concept and principle of software architecture, this paper introduces the concept of application framework, and studies the three application frameworks used in the development of the system: Struts,Spring and Hibernate,. At the same time, the combination of three kinds of frameworks is given. The result of system requirement analysis is used not only as the basis of software design, but also as the standard of software acceptance. The primary goal of the system design is to realize the specific business logic to support the business operation of the enterprise, then to meet the performance requirements, to have better availability, and to achieve smoother human-computer interaction. In this paper, the functional requirements, performance requirements and hardware and software environment constraints of the system are described in detail. The system design in this paper includes three aspects: system function module partition, system static structure design and system key business process design. The function module of the system is divided according to the functional requirement analysis, but it is no longer oriented to individual roles, but it considers the functions of all the roles comprehensively, integrates them and designs the modules reasonably. In the static structure design of the system, the definition of the class can be divided into two kinds: the first is the entity class, which represents the business entity in the business logic processed by the system. The second is the business logic processing class. The definition of the business processing class corresponds to the function items of each function module. The design of business process reflects the dynamic behavior of the system. Finally, this paper gives the implementation of the system, which consists of four parts: the development environment of the system, the implementation of business logic, the encryption of key information and error prevention and control. The system development environment describes the hardware environment and development tools of the system development. The business logic implementation of the system describes the implementation of MVC architecture, using Hibernate encapsulation data access layer and Struts Spring business layer implementation. The encryption of the key information adopts MD5 algorithm to encrypt the user's password information in one way, which ensures the security of the user's password. The purpose of error prevention and control is to avoid some uncontrollable reasons, and the user's operation may result in abnormal or normal data loss of the system.
