Spring-Cloud
1.创建注册中心:
pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>spring-cloud</groupId>
<artifactId>spring_cloud_eureka</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.7.RELEASE</version>
</parent>
<!-- dependencyManagement dependencies区别 如果在dependencyManagement 设置了版本信息 那在dependencies就不需要设置版本啦 -->
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Brixton.SR5</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka-server</artifactId>
</dependency>
</dependencies>
</project>
app.class
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer
public class ServerApp {
public static void main(String[] args) {
SpringApplication.run(ServerApp.class, args);
}
}
application.properties
#端口名称
server.port=6699
#服务名称
spring.application.name=master-service
#设置为false代表不注册自己服务
eureka.client.register-with-eureka=false
#由于注册中心的只测就是维护服务示例,他并不需要去检索服务,所以设置为false
eureka.client.fetch-registry=false
#地址
eureka.instance.hostname=127.0.0.1
#访问地址
eureka.client.serviceUrl.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka/
2.创建服务端注册到注册中心
pom.xml
<parent>
<groupId>org.springframework.boot</groupId>

<version>1.3.7.RELEASE</version>
</parent>

<dependency>

<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<!-- 要注册的需要引用 -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>

</dependency>
<!-- 加入断路器依赖 -->
<dependency>

</dependency>
</dependencies>
<!--依赖管理，用于管理spring-cloud的依赖，其中Camden.SR3是版本号 -->

</dependencies>
</dependencyManagement>
