Pork Cold Chain Vehicle Information Collection And Display System

With the impact of the African swine fever epidemic and the upgrading and development of the logistics industry,Beijing has introduced a new plan for pork from other provinces to enter Beijing,which has completely banned the entry of live pigs into Beijing,and instead uses the cold chain method to transport white pork.This change has greatly affected the business model of the slaughterhouse in Beijing.The focus of work has changed from live pig slaughtering to cold chain transportation of white strips.The new business will naturally generate new demands.This topic starts from this and is based on the actual situation.On the basis of on-the-spot research,the subject refers to the common mode of software engineering development and conducts research and development.Therefore,this article adopts the more common java web development technology stack,based on spring and various middleware,combined with mySQL database to complete the development of the whole system.And made research on the message queue middleware,compared and analyzed several common message queue products in large-scale development projects,and made technical selection based on the actual situation and problems faced.At the same time,the token-based authentication mode is also studied,and the design of JWT is used in the project.Starting from the actual project background,this paper first introduces the related technologies that will be used in the project,and then analyzes the requirements and technical points of the entire system through the object-oriented software engineering model.The queue middleware is compared and analyzed,and the main points and final results of self-designed message queue middleware are described.Finally,some conclusions are made on the research content and results.
