# eureka 服务的注册与发现
|
||
|
||
## 一、项目结构
|
||
|
||
eureka-server为服务注册中心，负责服务的管理；
|
||
|
||
eureka-client 为eureka客户端；
|
||

||

|
||
|
||
## 二、三步搭建eureka 服务注册中心
|
||
|
||
#### 2.1 引入eureka服务端依赖
|
||
|
||
```xml
|
||
<dependency>
|
||
<groupId>org.springframework.cloud</groupId>
|
||
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
|
||
</dependency>
|
||
```
|
||
|
||
#### 2.2 eureka 服务端配置
|
||
|
||
```yaml
|
||
server:
|
||
port: 8010
|
||
eureka:
|
||
instance:
|
||
hostname: localhost
|
||
client:
|
||
# 设置为false,代表不向注册中心注册自己
|
||
register-with-eureka: false
|
||
# 注册中心主要用于维护服务，并不需要检索服务，所以设置为false
|
||
fetch-registry: false
|
||
serviceUrl:
|
||
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
|
||
```
|
||
|
||
#### 2.3 启动类上增加注解@EnableEurekaServer激活eureka服务端自动配置
|
||
|
||
```java
|
||
@SpringBootApplication
|
||
@EnableEurekaServer
|
||
public class EurekaServerApplication {
|
||
|
||
public static void main(String[] args) {
|
||
SpringApplication.run(EurekaServerApplication.class, args);
|
||
}
|
||
|
||
}
|
||
```
|
||
|
||
## 三、三步搭建eureka 客户端
|
||
|
||
#### 3.1 引入eureka客户端依赖
|
||
|
||
```xml
|
||
<dependency>
|
||
<groupId>org.springframework.cloud</groupId>
|
||
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
|
||
</dependency>
|
||
```
|
||
|
||
#### 3.2 eureka 客户端配置
|
||
|
||
```yaml
|
||
server:
|
||
port: 8020
|
||
# 指定服务命名
|
||
spring:
|
||
application:
|
||
name: eureka-client
|
||
# 指定注册中心地址
|
||
eureka:
|
||
client:
|
||
serviceUrl:
|
||
defaultZone: http://localhost:8010/eureka/
|
||
```
|
||
|
||
#### 3.3 启动类上增加注解@EnableDiscoveryClient激活eureka客户端自动配置
|
||
|
||
```java
|
||
@SpringBootApplication
|
||
@EnableDiscoveryClient
|
||
public class EurekaClientApplication {
|
||
|
||
public static void main(String[] args) {
|
||
SpringApplication.run(EurekaClientApplication.class, args);
|
||
}
|
||
|
||
}
|
||
```
|
||
|
||
## 4.启动项目
|
||
|
||
#### 4.1 进入注册中心控制台，查看服务注册情况
