Spring Boot and Spring Cloud are two very popular Java development frameworks. They are both developed by Spring Framework, but their positioning and functions are different. This article will introduce the difference between Spring Boot and Spring Cloud.
1. Spring Boot
Spring Boot is a lightweight application framework designed to make Spring application development faster and easier. Spring Boot provides a rapid development environment through automatic configuration. Developers do not need to manually configure various dependencies and environments, but only need to add the required dependencies to quickly build a runnable application. Spring Boot also provides many commonly used functions, such as embedded web server, security, logging, monitoring and so on.
The advantage of Spring Boot is that it can quickly build a runnable application. Developers don't need to care about various tedious configurations, but only need to focus on the development of business logic. In addition, Spring Boot also provides some extensible mechanisms, such as custom starter and custom automatic configuration, so that developers can expand and customize according to their own needs.
2. Spring Cloud
Spring Cloud is a framework for building distributed systems. It is built on Spring Boot and provides some additional functions, such as service discovery, service governance, load balancing, circuit breakers, configuration centers, etc. The purpose of Spring Cloud is to help developers build highly available, scalable, and maintainable distributed systems.
The core components of Spring Cloud include:
- Eureka: Used to implement service discovery and registration.
- Zuul: Used to implement API gateways and routing.
- Ribbon: Used to achieve load balancing.
- Hystrix: Used to implement circuit breakers.
- Config: used to implement the configuration center.
The advantage of Spring Cloud is that it can help developers build distributed systems and provides some very useful functions, such as service discovery, load balancing, circuit breakers, etc., making it easier for developers to build highly available, scalable, scalable Maintained distributed systems.
3. The difference between Spring Boot and Spring Cloud
The main difference between Spring Boot and Spring Cloud is their positioning and functionality. The positioning of Spring Boot is to quickly build a runnable application. It provides common functions such as automatic configuration, embedded web server, security, log, monitoring, etc., so that developers can quickly build a runnable application. The positioning of Spring Cloud is to build a distributed system. It provides functions such as service discovery, load balancing, circuit breaker, and configuration center, making it easier for developers to build a highly available, scalable, and maintainable distributed system.
In addition, there are some differences between Spring Boot and Spring Cloud in use. Spring Boot can be used alone, while Spring Cloud needs to be built on Spring Boot. Developers can use Spring Boot to quickly build a runnable application, and then use Spring Cloud to build a distributed system. In addition, the components of Spring Cloud can be used independently. For example, Zuul can be used as an API gateway instead of Eureka for service discovery and registration.
Four. Summary
Spring Boot and Spring Cloud are two very popular Java development frameworks. They are both developed by Spring Framework, but their positioning and functions are different. The positioning of Spring Boot is to quickly build a runnable application. It provides common functions such as automatic configuration, embedded web server, security, log, monitoring, etc., so that developers can quickly build a runnable application. The positioning of Spring Cloud is to build a distributed system. It provides functions such as service discovery, load balancing, circuit breaker, and configuration center, making it easier for developers to build a highly available, scalable, and maintainable distributed system.
In general, both Spring Boot and Spring Cloud are excellent frameworks that can help developers quickly build high-quality applications or distributed systems. In actual development, developers can choose to use one or two of the frameworks according to their own needs to achieve the best development efficiency and quality.
