1.2 Overview of research at home and abroad
With the continuous development of the domestic economic situation, China's Internet has entered a rare period of peak development, which makes Chinese and foreign capitalists turn to the Internet market one after another. However, the unreasonable structure of many management areas, the shortage of personnel and the increase of management needs make more people have the awareness of Internet management.
In today's highly developed information, information management reform has become a more extensive and comprehensive trend. The "communication platform for mothers-to-be" is based on Mysql database and implemented on the basis of springboot framework programming. In order to ensure the sustainable development of China's economy, the information age has been updated and flourished day by day. At the same time, with the rapid development of the information society, expectant mothers' pregnancy communication platforms are faced with more and more information, so it is difficult to obtain their needs for efficient information. Exchange platform information is effective in querying, storing, managing and sharing information, and has important practical significance for our study, work and life. Therefore, the academic circles at home and abroad have conducted in-depth and extensive research on this, and a new research field - the platform for expectant mothers to communicate during pregnancy was born.
1.3 Contents of the study
At present, many people still use traditional paper tools as the main tool for information management, while the application of network technology only plays an auxiliary role. In terms of awareness of network tools, the more traditional office software is still the main tool people use, while the relatively comprehensive and professional information management software of the pregnancy communication platform for expectant mothers is still not understood or recognized by most people.

related technology
2.1 B/S Architecture
There are also many features of the B/S structure, for example, signal requests can be made in many browsers. And it can properly reduce the user's workload. By installing or configuring a small amount of running software on the client, the user's workload can be gradually reduced. The operation of these functions is mainly controlled by the server. Mature, the most important feature is that the cooperation with the browser brings great convenience to software development. It can not only reduce development costs, but also continuously strengthen the software functions of the system. The layers are independent of each other and the presentation layer is the B/S The structure completes the main features of the interconnection.
2.2 Java technology introduction
The Java language is good at developing Internet-type applications and enterprise-level applications. It is now quite mature, and it is also one of the most used programming languages. The Java language is very object-oriented and can be designed in line with the human thinking mode. Encapsulation is to hide the properties and methods of the object as much as possible, so that the outside world does not know how to achieve it, and the outside world can access it through the interface. Inheritance means that each class will have a parent class, and all subclasses have the methods of the parent class, which can be inherited, but only the final modified class cannot be inherited. Through inheritance, the code can be reused and the software can be improved. Development efficiency is also a prerequisite for polymorphism.
Like C language, C# language, etc., Java is also a program development language, and its characteristic is object-oriented. As a language for program development and design, it has many features, the main features of which are object-oriented, boasting platform, and distributed operation. Java language projects not only have high security and stability, but also can run concurrently.
In order to improve the speed and efficiency of development, it is necessary to reuse the code and simplify the complexity of the program. To meet the above requirements, the Java language is implemented through encapsulation, inheritance and polymorphism, which can achieve information encapsulation to a large extent. , improve code reuse rate, reduce redundancy, and improve efficiency. It alleviates the problem of memory leaks that existed in a large number of programs in the past. The so-called memory leak is that the program applies for a piece of storage space from the operating system, such as defining a variable, but for some reason, this variable has not been used, but still occupies the memory space of the system, maybe one or two such variables are right The program and the operating system will not have a big impact, but imagine that if there are too many such variables defined, the memory space of the system will be reduced step by step, resulting in reduced performance or even downtime of the machine. However, there is a garbage collection mechanism in Java, which greatly avoids the occurrence of memory leaks. In the Java virtual machine, the garbage collection mechanism will implement garbage collection for objects that have not been pointed to by reference variables for a long time. Simply put, Destroy this object to avoid memory leaks.
2.3 MySQL database introduction
MySQL is a Relational Database Management System, literally translated as a relational database management system, MySQL has its unique characteristics, these characteristics make it one of the most popular RDBMS, MySQL wants to compare with other databases such as ORACLE, DB2 etc. It is a database with small size and high speed. The key point is that it conforms to the real rental environment of this graduation project, has low cost of ownership, and has the characteristics of developing source code. This is also the main reason for choosing it.
This system uses the MySQL database, and establishes multiple database tables to store data related to rental and car rental platforms. The system mainly uses statements such as query (select), modification (update), deletion (delete) and increase (insert) to realize system functions.
2.4 Spring Boot framework
Spring Boot is a new framework from the Pivotal team aimed at simplifying the initial setup and development of new Spring applications. The framework uses a specific configuration approach, eliminating the need for developers to define boilerplate configurations. In this way, Spring Boot aims to be a leader in the burgeoning field of rapid application development.
Spring Boot features:
1. Create a separate Spring application;
2. Embedded Tomcat, no need to deploy WAR files;
3. Simplify Maven configuration;
4. Automatically configure Spring;
5. Provide production-ready features, such as indicators, health checks and external configuration;
6. Absolutely no code generation and XML configuration requirements;
installation steps:
At its most basic, Spring Boot is a collection of libraries that can be used by any project's build system. For simplicity, the framework also provides a command line interface that can be used to run and test Boot applications. Published versions of the framework, including the integrated CLI (command line interface), can be downloaded and installed manually from the Spring repository. An easier way is to use the Groovy enVironment Manager (GVM), which handles Boot version installation and management. Boot and its CLI can be installed from the GVM command line GVM install springboot. The Homebrew package manager can be used when installing Boot on OS X. To complete the installation, first switch to the pivotal repository using brew tap pivotal/tap and then execute the brew install springboot command.

第6章 系统测试
结 论
此时项目已经完成，即使实施的时间不是很长，但是这个过程中需要准备很长的一段时间去对系统设计开发所实际到的技术进行学习。在学习的过程中，我逐渐认识得到了我自身存在的一些不足。对于一些控制是必要的应用技能，能够理解，整个过程中仅仅是一个掌握了常用的性能和控制方法，我觉得挺容易的。从该系统中，系统的分析和设计的调查数据，并且已经经历了几个月，并努力几个月，该系统已经完成。很显然，该系统仍有很多不成熟，在系统设计过程中有许多技术缺陷存在。在设计的过程中也涉及到了很多自己无法解决的问题，主要通过找专业的网站和论坛来解决这些问题，对于圆满完成我的毕业设计，他们也贡献了很大一部分力量。系统的开发环境和配置都是可以自行安装的，系统使用springboot框架开发工具，使用比较成熟的Mysql数据库进行对系统前台及后台的数据交互，根据技术语言对数据库，结合需求进行修改维护，可以使得系统运行更具有稳定性和安全性，从而完成实现系统的开发。
回顾毕业设计的整个过程，既付出汗水也收获了很多。虽然经历了各种各样的困难，自己的不断研究探索，系统的实现仍有不足之处。
在以后的学习及工作中，我仍然继续学习计算机方面的技术，让我在后期的平台开发中可以更好更快的实现需求功能。
