Spring Boot
Spring Boot 项目旨在简化创建产品级的 Spring 应用和服务。你可通过它来选择不同的 Spring 平台。可创建独立的 Java 应用和 Web 应用，同时提供了命令行工具来允许 'spring scripts'.
本篇文章主要介绍了SpringBoot的服务注册与发现示例,具有一定的参考价值，感兴趣的小伙伴们可以参考一下
微服务
实践“微服务”自然要学习如何做服务注册与发现
基于SpringBoot来进行微服务的学习，自然选择了与之息息相关的SpringCloud;当然可以选择其他的技术进行，比如dubbo
也可以用zookeeper来实现服务注册与发现，至于zookeeper来实现此功能好还是不好，各家之言都有
SpringCloud
Spring Cloud provides tools for developers to quickly build some of the common patterns in distributed systems .SpringCloud
SpringCloud 包含了 Distributed/versioned configuration、Distributed/versioned configuration等很多子项目。
- Distributed/versioned configuration
- Service registration and discovery
- Routing
- Service-to-service calls
- Load balancing
- Circuit Breakers
- Global locks
- Leadership election and cluster state
- Distributed messaging
服务注册与发现
SpringCloud模块
spring-cloud-starter-eureka-server
工程module
- 服务注册中心
- 服务module
服务注册中心
创建discovery module,并在 build.gradle中引入 spring-cloud-starter-eureka-server依赖
apply plugin: 'org.springframework.boot'
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:"+ springCloudVersion
}
}
repositories {
mavenCentral()
}
dependencies {
compile ('org.springframework.cloud:spring-cloud-starter-eureka-server')
}
jar {
baseName = 'discovery-bootcwenao'
}
通过注解 @EnableEurekaServer 提供注册中心服务
/**
* @author cwenao
* @version $Id DiscoveryBootcwenaoApplication.java, v 0.1 2017-01-12 9:56 cwenao Exp $$
*/
@EnableEurekaServer
@SpringBootApplication
public class DiscoveryBootcwenaoApplication {
public static void main(String[] args) {
new SpringApplicationBuilder(DiscoveryBootcwenaoApplication.class).web(true).run(args);
}
}
application.yml 配置eureka属性
server:
port: 8761
eureka:
instance:
hostname: discovery
client:
registerWithEureka: false
fetchRegistry: false
service-url:
defaultZone: http://discovery:${server.port}/eureka/访问 http://localhost:8761
服务注册
创建服务module, 在build.gradle中引入 spring-cloud-starter-eureka
apply plugin: 'org.springframework.boot'
dependencyManagement {
imports {
mavenBom "org.springframework.cloud:spring-cloud-dependencies:"+ springCloudVersion
}
}
dependencies {
compile('org.springframework.cloud:spring-cloud-starter-eureka')
compile('org.springframework.cloud:spring-cloud-stream')
}
sourceSets {
main {
resources.srcDirs = ['src/main/resources', 'src/main/java']
resources.includes = ['**/*.xml', '**/*.yml']
}
}
jar {
baseName = 'apigateway-bootcwenao'
}
通过注解 @EnableDiscoveryClient 进行服务注册
@SpringBootApplication
@EnableDiscoveryClient
public class ApiGatewayBootcwenaoApplication {
public static void main(String[] args) {
SpringApplication.run(ApiGatewayBootcwenaoApplication.class, args);
}
}
application.yml 配置eureka属性
server:
port: 10002
spring:
application:
name: apigateway
eureka:
client:
registerWithEureka: true
fetchRegistry: true
serviceUrl:
defaultZone: http://localhost:8761/eureka/
注册完成后，可以通过 spring.application.name 的配置来访问该服务
访问 http://localhost:8761 发现服务已经在注册中心上注册
服务注册中心启用用户名密码
通过配置applicaiton.yml用户名密码
security:
basic:
enabled: true
user:
name: aa
password: abcd配置服务提供方application.yml
eureka:
instance:
hostname: configserver
prefer-ip-address: true
client:
registerWithEureka: true
fetchRegistry: true
service-url:
defaultZone: http://aa:abcd@localhost:8761/eureka/
