The Research And Design Of Maintaining Stability Information Management System Based On J2EE

At the present stage,China is undergoing a period of intense social transformation.There will be various social problems and conflicts triggered by the restructuring of society.Instability incidents triggered by contradictions among the people become more frequent.The growing problem of social stability has become an important factor affecting the process of reform and development.This thesis designed and developed a stable information management system based on J2 EE technology architecture.SSM(Spring+SpringMVC+MyBatis)framework set was adopted for system development.Combined with fuzzy search methods to filter information data,Through the intelligent classification of the information of maintaining stability,the purpose of timely warning and improving work efficiency can be achieved.The main studying contents of this thesis are as follows: Firstly,the system introduced the text analysis technology,including Chinese word segmentation tool Ansj,classification algorithm SVM and other machine learning content,which is the key technology for the system to achieve intelligent early warning.Secondly,this thesis analyzed the functional requirements and business requirements of the system,elaborates on the functions that each major module of the system needs to achieve,and introduces some non-functional requirements.Finally,designed system as a three-tier architecture,set up the required software environment,designed the database structure of the system for the functions that need to be implemented,given the main database table and E-R diagram,and then on the basis of the module design to carry on the development and implementation,five modules are as examples to show manual and the main interface.The system is an internal information management system that extends to all public security bureaus and branches of the city.It is capable of identifying case type,generating fixed format documents,querying,statistical analysis,etc.The integrated office system has played an important role in improving the efficiency of government departments.
