Redis项目（一）项目搭建

Redis项目（一）项目搭建

项目架构

基于微服务进行开发，微服务是目前比较热门的架构方式，具有以下特点：

• 职责单一：理论上一个微服务只解决一件事（小）
• 隔离性强：服务单独部署，服务之间互相隔离，互不影响，因此一个服务宕机并不影响其他服务运行。

项目基础搭建

基于Spring Cloud Hoxton.SR8搭建。

第一步：创建Maven的父级工程，添加对应依赖

第二步：创建基于Eureka的注册中心微服务

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloudgroupId>
            <artifactId>spring-cloud-starter-netflix-eureka-serverartifactId>
        dependency>
    dependencies>

server:
  port: 8080

spring:
  application:
    name: ms-registry

# 配置 Eureka Server 注册中心
eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://localhost:8080/eureka/

第三步：添加网关微服务

    <dependencies>
        
        <dependency>
            <groupId>org.springframework.cloudgroupId>
            <artifactId>spring-cloud-starter-gatewayartifactId>
        dependency>
        
        <dependency>
            <groupId>org.springframework.cloudgroupId>
            <artifactId>spring-cloud-starter-netflix-eureka-clientartifactId>
        dependency>
    dependencies>

server:
  port: 80

spring:
  application:
    name: ms-gateway
  cloud:
    gateway:
      discovery:
        locator:
          enabled: true # 开启配置注册中心进行路由功能
          lower-case-service-id: true # 将服务名称转小写
      routes:
        - id: ms-diners # 这里的id是标识这个路由规则的唯一标识符
          uri: lb://ms-diners #lb：负载均衡
          predicates:
            - Path=/hello/**  #路径为 /hello/** 的请求转发到名为 ms-diners 的微服务
# 配置 Eureka Server 注册中心
eureka:
  instance:
    prefer-ip-address: true
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
  client:
    service-url:
      defaultZone: http://localhost:8080/eureka/

第四步：添加用户食客微服务

        <dependency>
            <groupId>org.springframework.cloudgroupId>
            <artifactId>spring-cloud-starter-netflix-eureka-clientartifactId>
        dependency>
        
        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-webartifactId>
        dependency>

server:
  port: 8081 # 端口

spring:
  application:
    name: ms-diners # 应用名

@RestController
@RequestMapping("hello")
public class HelloController {

    @GetMapping
    public String hello(String name) {
        return "hello " + name;
    }

}

第五步：启动测试

访问localhost/hello?name=fengzi

因为网关端口80,80端口是浏览器默认端口，所以可以省略端口号

public String hello(String name) {
    return "hello " + name;
}

}

### 第五步：启动测试

访问[localhost/hello?name=fengzi](http://localhost/hello?name=fengzi)
