SpringCloud implements service registration and discovery through Eureka

For Spring Cloud's service registration and discovery through Eureka, the Maven coordinates of commonly used dependency class libraries are as follows: <dependencies> <!-- Spring Boot Web Starter --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- Spring Cloud Eureka Client --> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency> </dependencies> A brief introduction to these dependent class libraries is as follows: 1. 'spring boot starter web': The basic dependency library used to create Spring Boot applications, which includes the Web MVC framework and required dependencies. 2. 'spring cloud starter netflix eureka client': The Eureka client dependency library provided by Spring Cloud provides the ability to register applications with Eureka servers and discover other services. The following is a complete example that demonstrates how to use Spring Cloud and Eureka to complete service registration and discovery. Firstly, create a Spring Boot application class' SpringCloudEurekaClientApplication 'and add' @ Enable EurekaClient 'in the annotation' @ SpringBootApplication 'to enable the Eureka client. import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.EnableEurekaClient; @SpringBootApplication @EnableEurekaClient public class SpringCloudEurekaClientApplication { public static void main(String[] args) { SpringApplication.run(SpringCloudEurekaClientApplication.class, args); } } Then, create a controller class' HelloController 'to handle HTTP requests and return responses. import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class HelloController { @GetMapping("/") public String index() { return "Hello, Eureka Client!"; } } Finally, configure the address of the Eureka server in the 'application. properties' file. properties spring.application.name=hello-service eureka.client.service-url.default-zone=http://localhost:8761/eureka/ After completing the above code writing and configuration, run the 'SpringCloudEurekaClientApplication' class. The application will automatically register itself with the Eureka server and can be accessed through the` http://localhost:8761 `Visit the Eureka console to view registered services. Summary: By using Spring Cloud and Eureka, service registration and discovery can be easily achieved. By simple configuration and a few lines of code, the application can be registered with the Eureka server and communication and discovery between services can be achieved. At the same time, Spring Cloud also provides rich functions, such as load balancing, fuses, etc., making the development of Microservices architecture simpler and more reliable.
