The Design And Implementation Of Intelligent Temperature Sharing System Based On J2EE

With the rapid development of Mobile Internet,Mobile Health is increasingly valued by people.In Mobile Health,the monitoring and measuring on human body temperature is a vital indicator in obtaining the health status of the human body.However,the traditional thermometer can only perform single measurement on temperature and has no recording function.In order to address these problems,this dissertation proposes the intelligent temperature sharing system based on J2EE.This system can offer people precise temperature measurement,save temperature information,and record the trend of body temperature variation over a period of time.And it can also share body temperature information with other people,thus getting corresponding health advice.Based on the development of J2EE technology,this dissertation finishes the design and implementation of intelligent temperature sharing system.This dissertation firstly studies the J2EE specified technologies,and designs overall system framework based on MVC pattern.Secondly,this dissertation researches into relevant database technologies,designs and implements the system database.Thirdly,based on the framework of Spring and Hibernate,this dissertation finishes the system development work,defines system interfaces,and designs data transmission scheme based on JSON and management strategy of transaction.Finally,in order to make the system possess better maintainability and extendibility,this dissertation investigates the design patterns and their application in the system.In addition,this dissertation designs optimization strategies for the system in very high concurrency situations.Firstly,this dissertation analyzes the main characteristics of high concurrency system,and gives analysis and summary on the design and optimization scheme of high concurrency system from the two aspects of database and thread pool.As for database,major factors that affect database performance are analyzed,and database is optimized from the three aspects of SQL statements tuning,read-write splitting database and reasonable application of index.As for thread pool,basic principle of thread pool is analyzed,optimization strategies for thread pool are designed through the analyses of simulation results.
