01.SpringCloud中Eureka Server及其Eu

一.创建并且配置Eureka Server

01.可以在创建spring initialize的勾上Eureka Server

02.配置pom文件

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

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Finchley.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

03.配置启动类为Eureka server

@SpringBootApplication
//创建服务注册中心
@EnableEurekaServer
public class StartMain {
...
}

04.application.yml配置

server:
  port:7777    //端口号
eureka:
  client:
    service-url:
       defalutZone:http://localhost:7777/eureka/  //若果有多个eureka server就用逗号隔开
    fetch-registry: false  //禁止两个eureka server互相抓取内容，因为这是一个单点的EurekaServer，不需要同步其它EurekaServer节点的数据，故设为false
    register-with-eureka:false //禁止注册eureka server，因为它已经是了  自己注册自己 没有意义，其他的客户端项目可以注册这个eureka server。

二.创建并且配置Eureka Discovery

01.可以在创建spring initialize的勾上Eureka Discovery

02.pom文件的配置

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>        
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            <version>2.0.0.RELEASE</version>
        </dependency>
    </dependencies>
<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Finchley.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

03.配置client启动类

@SpringBootApplication
@EnableEurekaClient
public class StartMain {
...
}

04.application.yml配置

server:
  port:8080   //作为一个web项目，端口必须的配置
spring:
  application:
    name:user-provider     //eureka client的名字
eureka:
  client:
    service-url:
      defaultZone:http://localhost:7777/eureka/    //配置注册到eureka server的地址

三.给Eureka server添加用户名密码

01.在Eureka server中导入依赖

<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>

02.在yml文件中配置用户名可密码

security:
  basic:
    enabled: true
user:
  name: root
  password: 123456

03.给client配置security中的账号和密码 不然client就无法访问server

在client中的yml文件中配置
defaultZone: http://root:123456@localhost:7777/eureka/
