Performance optimization and best practices
Posted: Thu Jan 23, 2025 8:44 am
In the development of RESTful API, in addition to functional implementation, performance optimization is also an aspect that cannot be ignored. Here are some optimization tips:
1. Asynchronous processing
Spring Boot supports asynchronous requests. You can use @Asyncannotations to make some time-consuming operations (such as database queries and external API calls) asynchronous, thereby improving the response performance of the API.
2. Cache mechanism
For some repeatedly queried data, you can use cache to reduce jordan mobile phone number list database access and improve API response speed. Spring Boot provides integration with cache frameworks such as Redis, .EhCache
Example: Using Redis Cache
First, add the Redis dependency:
Through @Cacheableannotations, Spring will cache the query results to avoid repeated queries to the database.
3. Data paging and filtering
When the amount of data is large, the API response time may be slow. Paging and filtering can effectively reduce the server burden and improve performance.
Example: Paginated Query
Implement the paging function in UserService:
This method can effectively control the amount of data returned and avoid returning too much data at one time, resulting in slow response.
4. Current Limitation and Prevention of Malicious Requests
To prevent abuse or malicious attacks, we can limit the frequency of API calls through a current limiting strategy. For example, use tools such as Bucket4j, Redisto implement API request frequency limits.
Developing RESTful APIs with Spring Boot can not only improve development efficiency, but also provide rich functions and scalability. This article demonstrates how to create a simple user management RESTful API through examples, and introduces JWT authentication, performance optimization and other aspects. In actual development, we should flexibly use the features of Spring Boot according to project requirements to build efficient, secure and maintainable RESTful APIs.
