3.Sping Cloud组件之Eureka_java好学生

3.1.创建Springboot项目

3.2.项目pom依赖

3.3.application.yml配置

server:

port: 6060 #Eureka Server和Tomcat端口(不配默认8761,Tomcat8080)

spring:

application:

name: eureka #应用名称，也就是微服务名称，不写默认空

security: #注册到eureka需要用户名和密码

user:

name: admin

password: 123

?

eureka:

server:

enable-self-preservation: false #禁用保护,默认true

eviction-interval-timer-in-ms: 10000 #清理间隔（默认是60*1000）

client:

fetch-registry: false #是否从eureka server获取服务信息，默认true

register-with-eureka: false #是否向eureka server注册，默认true

service-url:

defaultZone: http://localhost:6060/eureka/ #注册地址(不配默认8761)

3.4.启动类：

@SpringBootApplication

@EnableEurekaServer

publicclassKgc47eureka6060Application {

?

publicstaticvoidmain(String[] args) {

SpringApplication.run(Kgc47eureka6060Application.class, args);

}

?

}

3.5.设置csr检查（坑）

在2.0以后，需要加入这个检查设置，不然eureka-client无法注册到eureka-server上去

@EnableWebSecurity

publicclassWebSecurityConfigextendsWebSecurityConfigurerAdapter {

?

@Override

protectedvoidconfigure(HttpSecurityhttp) throwsException {

http.csrf().disable(); //禁止使用csr验证

super.configure(http);

}

}

3.6.运行访问

3.7.创建eureka-client客户端项目(除了eureka server注册中心以外其他都是eureka-客户端（都要导web包，其他包情况而定）)

仍然是创建springboot项目，只是在选择组件的注意

3.8.项目pom依赖

<?xmlversion="1.0" encoding="UTF-8"?>

<projectxmlns="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 " target="_blank">https://maven.apache.org/xsd/maven-4.0.0.xsd">

</project>

3.9.application.yml配置

提供者：

server:

port: 7001

?

spring:

application:

name: provider

?

eureka:

client:

register-with-eureka: true #向eurek server 注册

fetch-registry: true #获取信息列表

service-url:

defaultZone: http://admin:123@localhost:6001/eureka/ #注意用户名和密码 @

3.10.启动类

@SpringBootApplication

@EnableEurekaClient与@EnableDiscoveryClient（这个注解可以向任何注册中心注入）一样

publicclassKgc47consumer8090Application {

?

publicstaticvoidmain(String[] args) {

SpringApplication.run(Kgc47consumer8090Application.class, args);

}

?

}

3.11.查看eureka主页

访问 http://127.0.0.1:6060 ，在applications中显示客户端信息
