SpringCloud Eureka註冊中心使用

SpringCloud版本區別java

1、maven依賴配置,SpringCloud目前有四個版本,經測試Camden,Dalston兩個版本構建Eureka正常,其它兩版本存在jar依賴問題,因此選取Dalstont版本,目前採用最新和SR5 依賴以下spring

<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>



	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	</properties>

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.5.9.RELEASE</version>
	</parent>
	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>Dalston.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>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-security</artifactId>
		</dependency>
	</dependencies>
	<build>
		<resources>
			<resource>
				<directory>src/main/java</directory>
			</resource>
			<resource>
				<directory>src/main/resources</directory>
			</resource>
		</resources>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<configuration>
					<source>1.8</source>
					<target>1.8</target>
					<encoding>UTF-8</encoding>
				</configuration>
			</plugin>
		</plugins>
	</build>
</project>

2、Eureka啓動,propertySource加載配置文件路徑,默認引入resources下的application.propertiesapache

@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的配置安全

 1.獨立模式 registerWithEureka,fetchRegistry關閉註冊app

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

2.集羣模式 eureka.client.serviceUrl.defaultZone相互註冊實現集羣化maven

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

3.安全認證模式 defaultZone必定要配置,用於服務地址註冊,默認不配啓用8761端口spring-boot

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
