Example project path

The first step is to rely on

Dependencies required by the server in Maven's .pom file:

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-eureka</artifactId>
        <version>1.3.1.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
        <version>1.5.3.RELEASE</version>
        <exclusions>
            <exclusion>
                <groupId>com.fasterxml.jackson.core</groupId>
                <artifactId>jackson-databind</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

The second step is to configure

Define a configuration file, either named application.yml or application.properties.

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8762/eureka/
server:
  port:
    9999
spring:
  application:
    name: provider

The third step, service class

Build a service provider class, take rest as an example:

package com.silence.spring.cloud.provider;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class ProviderController {

    @RequestMapping("/getInfo")
    public String getInfo() {

        return "provider";

    }

}

The fourth step, start

Build the startup class:

package com.silence.spring.cloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication
@EnableEurekaClient
public class ProviderApplication {

    public static void main(String[] args) {

        SpringApplication.run(ProviderApplication.class, args);

    }

}

verify

Similarly, check the registration center http://localhost:8762/ , if the following figure appears, it proves that the service registration is successful.
