With the development of Internet applications, the functions of application programs are becoming more and more complex, which makes the real-time requirements of business data generation become higher. In order to improve user experience and response speed, applications need to receive and process data from various data sources in real time, such as user behavior logs, device status information, and operational data. Traditional solutions include using WebSocket technology to request data based on polling or HTTP long polling. However, these solutions have the following problems:
- Difficulty in development: Both traditional WebSocket and polling mechanisms require front-end pages to write corresponding codes, and developers need to be familiar with asynchronous programming, JavaScript, HTML5 and other related technologies; at the same time, the server-side also needs to design WebSocket interfaces to implement corresponding logic.
- Low performance: Since the client frequently sends requests, the server will be overloaded; the polling method is inefficient and unreliable because it consumes resources and continuously queries the database.
- Unable to cope with complex business requirements: When the types of business data sources are diverse and the data flow is changeable, the traditional WebSocket and polling mechanisms still cannot meet the requirements.
Therefore, the "Message Queue" (Message Queue) provided by the cloud computing platform has become a new infrastructure layer technology in the service architecture. The message queue is a typical advanced distributed middleware component, which decouples the application program from the message middleware, and can be used for asynchronous transmission, decoupling system dependencies, and improving overall performance.
This article will introduce how to use the integration of RabbitMQ message queue and Spring Boot RESTful API. I hope that this article can explain in detail how the message queue integrates with the Spring Boot RESTful API, and how to deal with complex business scenarios, so as to improve the ease of use, scalability, usability and maintainability of the RESTful API.
