Comparison of similarities and differences between Spring Cloud and Spring Boot from an architectural perspective
Spring Cloud and Spring Boot are currently the most popular microservice development frameworks in the Java field. They are both Derived from Spring Framework. Although they are both used to build enterprise-level applications, there are some differences at the architectural level. This article will compare Spring Cloud and Spring Boot from the architectural level, and illustrate their similarities and differences through specific code examples.
Overall Architecture
Service Registration and Discovery
Specific code examples:
(1) Spring Boot application code examples using Eureka for service registration and discovery:
@SpringBootApplication @EnableEurekaClient public class UserServiceApplication { public static void main(String[] args) { SpringApplication.run(UserServiceApplication.class, args); } }
(2) Spring Cloud application code example using Eureka for service registration and discovery:
@SpringBootApplication @EnableDiscoveryClient public class UserServiceApplication { public static void main(String[] args) { SpringApplication.run(UserServiceApplication.class, args); } }
Load Balancing
Specific code examples:
(1) Spring Boot application code examples using Ribbon to achieve load balancing:
@Bean @LoadBalanced public RestTemplate restTemplate() { return new RestTemplate(); }
(2 ) Spring Cloud application code example using Ribbon to achieve load balancing:
@SpringBootApplication @EnableDiscoveryClient public class UserServiceApplication { public static void main(String[] args) { SpringApplication.run(UserServiceApplication.class, args); } @Bean @LoadBalanced public RestTemplate restTemplate() { return new RestTemplate(); } }
Through the above example code, we can see that Spring Cloud pays more attention to the architectural design of distributed systems than Spring Boot, providing A complete set of microservice solutions has been developed. Spring Boot focuses more on simplifying the creation and deployment of Spring applications. In actual applications, you can choose an appropriate framework to build applications based on specific needs.
