​​springcloud整合eureka实现服务注册与发现​​

1.项目目录：

2.代码实现：

创建eureka父类服务，pom添加依赖

 <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.6.2</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.cxh</groupId>
    <artifactId>eureka</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>eureka</name>
    <description>Demo project for Spring Boot</description>
    <packaging>pom</packaging>
    <properties>
        <java.version>1.8</java.version>
        <spring-cloud-dependencies.version>2021.0.0</spring-cloud-dependencies.version>
    </properties>

    <dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>$spring-cloud-dependencies.version</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
    </dependencyManagement>

创建module模块eureka-server服务

添加依赖

 <parent>
        <groupId>com.cxh</groupId>
        <artifactId>eureka</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.cxh</groupId>
    <artifactId>server</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>server</name>
    <description>Demo project for Spring Boot</description>
    <properties>
        <java.version>1.8</java.version>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
            <version>1.4.7.RELEASE</version>
        </dependency>
    </dependencies>

yml配置

server:
  port: 8001

eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://localhost:$server.port/eureka/

启动器添加注解

@EnableEurekaServer
@SpringBootApplication
public class ServerApplication 

    public static void main(String[] args) 
        SpringApplication.run(ServerApplication.class, args);
    

创建module模块eureka-client服务

添加依赖

 <parent>
        <groupId>com.cxh</groupId>
        <artifactId>eureka</artifactId>
        <version>0.0.1-SNAPSHOT</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.cxh</groupId>
    <artifactId>eureka-client</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>eureka-client</name>
    <description>Demo project for Spring Boot</description>
    <properties>
        <java.version>1.8</java.version>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

    </dependencies>

yml配置

server:
  port: 8002



eureka:
  client:
    service-url:
      defaultZone: http://localhost:8001/eureka/

spring:
  application:
    name: eureka-client

启动器添加注解

@EnableEurekaClient
@SpringBootApplication
public class EurekaClientApplication 

    public static void main(String[] args) 
        SpringApplication.run(EurekaClientApplication.class, args);
    

3.实现效果：

运行eureka-server， eureka-client项目， 浏览器打开​​http://localhost:8001/​​
