SpringCloud Eureka注册中心使用

SpringCloud版本区别

1、maven依赖配置，SpringCloud目前有四个版本，经测试Camden,Dalston两个版本构建Eureka正常，其它两版本存在jar依赖问题，因此选取Dalstont版本，目前采用最新和SR5 依赖以下

<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>com.pkfare</groupId>
	<artifactId>eureka</artifactId>
	<version>1.0.0</version>
	<packaging>jar</packaging>

					<target>1.8</target>
					<encoding>UTF-8</encoding>
				</configuration>
			</plugin>
		</plugins>
	</build>
</project>

2、Eureka启动，propertySource加载配置文件路径，默认引入resources下的application.properties

@SpringBootApplication
@EnableEurekaServer
@PropertySource("file:/var/server-config/eureka/config.properties")
public class Application {
	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}
}

3、Eureka的配置

 1.独立模式 registerWithEureka,fetchRegistry关闭注册

spring.application.name=eureka-server
server.port=8889
eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false

2.集群模式 eureka.client.serviceUrl.defaultZone相互注册实现集群化

spring.application.name=eureka-server
server.port=8889
eureka.client.serviceUrl.defaultZone=http://127.0.0.1:8888/eureka/

3.安全认证模式 defaultZone必定要配置，用于服务地址注册，默认不配启用8761端口

spring.application.name=eureka-server
server.port=8889
eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false
security.basic.enable=true
security.user.name=vito
security.user.password=123456
eureka.client.serviceUrl.defaultZone=http://vito:123456@127.0.0.1:8889/eureka/
eureka.client.healthcheck.enabled=true
