spring boot 2.x版本下使用spring cloud配置eureka

spring 2.X版本下和1.5的依赖有区别。主要是eureka变成了netflix-eureka

一、首先是server项目：
1.pom.xml：

<?xml version="1.0" encoding="UTF-8"?>

4.0.0

<groupId>com.example</groupId>
<artifactId>test-springcloud-client</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>

<name>test-springcloud-client</name>
<description>Demo project for Spring Boot</description>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.0.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
</properties>

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

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <!--eureka依赖-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-eureka</artifactId>
    </dependency>

    <!--server方依赖-->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
    </dependency>
</dependencies>

<!--管理spring cloud所有组件的版本-->
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Finchley.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
            <exclusions>
            </exclusions>
        </dependency>
    </dependencies>
</dependencyManagement>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

2.application.yml：

server:
port: 8989
spring:
profiles:
active: dev
eureka:
server:
enable-self-preservation: false
instance:
preferIpAddress: true
hostname: ${spring.cloud.client.ip-address}
instanceId: ${spring.cloud.client.ip-address}:$ {server.port}
client:
registerWithEureka: false
fetchRegistry: false
serviceUrl:
defaultZone: http:// ${eureka.instance.hostname}:$ {server.port}/eureka/

3.启动类上加@EnableEurekaServer

二、client客户端：
1.pom.xml

<?xml version="1.0" encoding="UTF-8"?>

4.0.0

<groupId>com.example</groupId>
<artifactId>test-springcloud-client</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>

<name>test-springcloud-client</name>
<description>Demo project for Spring Boot</description>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.0.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
</properties>

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

<!--管理spring cloud所有组件的版本-->
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Finchley.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
            <exclusions>
            </exclusions>
        </dependency>
    </dependencies>
</dependencyManagement>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

2.application.yml

eureka:
client:
serviceUrl:
defaultZone: http://localhost:8989/eureka/
server:
port: 8081
spring:
application:
name: hello

3.启动类上加@EnableEurekaClient
4.写一个controller方法

三、测试
访问 localhost:8989就能访问到注册中心，可以看到client方发布的name=hello，的服务在这里插入图片描述

要访问服务，可以使用192.168.1.109：8081/请求名

spring boot 2.x版本下使用spring cloud配置eureka
