摘 要
房屋是人类生活栖息的重要场所，随着城市中的流动人口的增多，人们对房屋租赁需求越来越高，为满足用户查询房屋、预约看房、房屋租赁的需求，特开发了本基于Spring Boot的房屋租赁系统。
本文重点阐述了房屋租赁系统的开发过程，以实际运用为开发背景，基于Spring Boot框架，运用了Java技术和MYSQL数据库进行开发，充分保证系统的安全性和稳定性。本系统界面良好，操作简单方便，通过系统概述、系统分析、系统设计、数据库设计、系统测试这几个部分，详细的说明了系统的开发过程，最后并对整个开发过程进行了总结，实现了房屋租赁的功能。
本基于Spring Boot的房屋租赁系统运行效果稳定，操作方便、快捷，界面友好，是一个功能全面、实用性好、安全性高，并具有良好的可扩展性、可维护性的房屋租赁平台。

Abstract
Housing is an important place for human life. With the increase of the floating population in the city, people’s demand for housing rental is getting higher and higher. Boot's housing rental system.
This article focuses on the development process of the housing rental system, taking actual application as the development background, based on the Spring Boot framework, using Java technology and MYSQL database for development, and fully ensuring the security and stability of the system. The system has a good interface, simple and convenient operation. Through the system overview, system analysis, system design, database design, system testing, the development process of the system is explained in detail. Finally, the whole development process is summarized and realized The function of house leasing.
The Spring Boot-based house leasing system has stable operation effect, convenient and fast operation, and friendly interface. It is a house leasing platform with comprehensive functions, good practicability, high safety, and good scalability and maintainability.
Key words：House rental, Java technology, MYSQL database, Spring Boot framework
