2 Key Technology Introduction
2.1 Spring boot framework
This technology is an open source application framework of the Java platform, and its purpose is to simplify the initial construction and development process of Sping. By default, the usage of many frameworks is configured, and the Jar package is automatically loaded, in order to allow members to run the spring application as quickly as possible.
The main advantages of SpinrgBoot are:
Provides a faster and broader entry experience for all spring development;
zero configuration;
Integrate the configuration of a large number of commonly used third-party libraries;
Provide ready features. Today, developers in the Java field are using SpinrgBoot, gradually becoming a leader in the development field.
2.2 Java language
The Java language is a complete object-oriented programming language. The idea of an object-oriented programming language is to regard objectively existing things as a type of object with state and behavior, and then find out the common state and behavior of the same type of object through an abstract method to form a model—class. Class is the core of the Java programming language and the basic abstract unit of the Java language. All kinds of things in the world are objects, which can be abstracted into classes with state and behavior. The main features of the Java language are:
Java language is a typical object-oriented. It provides classes, and classes provide object models. By using inheritance and polymorphism, code reuse can be achieved.
The Java language is safe. The biggest problem to be solved in the contemporary network environment is the security problem. Java has internal security measures to ensure the safety and integrity of the program.
The operation of the Java language is platform-independent. Java programs can run on any system, as long as the Java operating system is installed.
The Java language is multithreaded.
The Java language has memory management. Java can automatically manage memory, making good use of system resources and reducing waste.
2.3 MYSQL database technology
2.3.1 Introduction to MYSQL database technology
Using MYSQL's data independence, security and other characteristics to operate data in software projects can ensure the accuracy of data and reduce the application development time of programmers.
MYSQL supports the characteristics of multi-threading, which can conveniently use system resources and effectively improve the speed, and provides TCP/IP, ODBC and JDBC and other ways to connect to the database; although its functions are not powerful enough and the scale is relatively small, but It is sufficient for this system, and the expansion of the database table structure space for secondary development can also be carried out at the same time [4].
Using MYSQL to establish a system database is not only conducive to the early integration of data processing services, but also conducive to the development of the latter two data expansion operations.
2.3.2 Features of MYSQL database
