搭建spring cloud2.0基础框架
推荐使用idea作为ide,使用git作为版本管理工具,在idea中安装eclipse code fomatter后配置代码格式化工具，业务框架集成dev-tool做为热启动工具,推荐使用yml作为配置文件格式,更直观简洁
由于是spring cloud2,如果感觉下载依赖缓慢，建议修改一下maven的代理，添加一下到原来的<mirros>节点中,如下：
<mirror>
<!--This sends everything else to /public -->
<id>nexus</id>
<mirrorOf>*</mirrorOf>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
</mirror>
<mirror>
<!--This is used to direct the public snapshots repo in the
profile below over to a different nexus group -->
<id>nexus-public-snapshots</id>
<mirrorOf>public-snapshots</mirrorOf>
<url>http://maven.aliyun.com/nexus/content/repositories/snapshots/</url>
</mirror>
<mirror>
<id>UK</id>
<name>UK Central</name>
<url>http://uk.maven.org/maven2</url>
<mirrorOf>central</mirrorOf>
</mirror>
<mirror>
<id>sonatype</id>
<name>sonatype Central</name>
<url>http://repository.sonatype.org/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>高可用的注册中心
首先,你需要看到主要依赖是以下:
<!--eureka server注册中心-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>pom.xml文件中的书写格式推荐类似如下：
<?xml version="1.0" encoding="UTF-8"?>
<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.tristan</groupId>
<artifactId>registry-server</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<name>registry-server</name>
<description>注册中心服务器</description>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.3.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<!-- 将版本信息抽出来方便以后进行调整-->
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
<spring-cloud.version>Finchley.RELEASE</spring-cloud.version>
</properties>
<dependencies>
<!--eureka server注册中心-->
<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>${spring-cloud.version}</version><!-- 动态引用版本号-->

</dependency>
</dependencies>

<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>然后,需要配置配置文件,如下：
---
server:
port: 8771
spring:
profiles: peer1
application:
name: registry-server
eureka:
instance:
hostname: peer1
lease-expiration-duration-in-seconds: 15 # 剔除注册记录的最大容忍失联时间
lease-renewal-interval-in-seconds: 5 # 注册中心主动心跳的时间间隔
client:
serviceUrl:
defaultZone: http://localhost:8772/eureka/,http://localhost:8773/eureka/
server:
response-cache-update-interval-ms: 3000 # 从注册可用到真正可用的时间
response-cache-auto-expiration-in-seconds: 180 # 注册方注册保障的有效时间或者失效时间
eviction-interval-timer-in-ms: 3000 # 注册中心主动监测失效的时间间隔
# enable-self-preservation: false # 关闭自我保护
---
server:
port: 8772
spring:
profiles: peer2
application:
name: registry-server
eureka:
instance:
hostname: peer2
lease-expiration-duration-in-seconds: 15 # 剔除注册记录的最大容忍失联时间
lease-renewal-interval-in-seconds: 5 # 注册中心主动心跳的时间间隔
client:
serviceUrl:
defaultZone: http://localhost:8771/eureka/,http://localhost:8773/eureka/
server:
response-cache-update-interval-ms: 3000 # 从注册可用到真正可用的时间
response-cache-auto-expiration-in-seconds: 180 # 注册方注册保障的有效时间或者失效时间
eviction-interval-timer-in-ms: 3000 # 注册中心主动监测失效的时间间隔
# enable-self-preservation: false # 关闭自我保护
---
server:
port: 8773
spring:
profiles: peer3
application:
name: registry-server
eureka:
instance:
hostname: peer3
lease-expiration-duration-in-seconds: 15 # 剔除注册记录的最大容忍失联时间
lease-renewal-interval-in-seconds: 5 # 注册中心主动心跳的时间间隔
client:
serviceUrl:
defaultZone: http://localhost:8771/eureka/,http://localhost:8772/eureka/
server:
response-cache-update-interval-ms: 3000 # 从注册可用到真正可用的时间
response-cache-auto-expiration-in-seconds: 180 # 注册方注册保障的有效时间或者失效时间
eviction-interval-timer-in-ms: 3000 # 注册中心主动监测失效的时间间隔
# enable-self-preservation: false # 关闭自我保护 注册中心只是作为高可用即可，无需特别多台,当一台注册中心宕机时,后台hock设置重启即可,同时其他服务的注册由于同等配置可随时切入。
由于多台互相注册所以连入任何一台都能看到相同的服务状态注册列表
通过springBoot方式启动工程,RegistryServerApplication:
package com.tristan.registryserver;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@SpringBootApplication
@EnableEurekaServer //如果不加该注解或者在配置文件中配置则会导致启动失败，不保持启动状态，后台持续报错，访问eureka界面提示404
public class RegistryServerApplication {
public static void main(String[] args) {
SpringApplication.run(RegistryServerApplication.class, args);
}
}成功启动之后的日志:(开始时的报错为正常现象)

首先，配置依赖(注意:普通子服务需要web依赖才能正常启动）:
<!--web依赖,服务提供方必备-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--服务发现组件-->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<!--监控-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<!--dev-tool热启动-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<scope>runtime</scope>
</dependency>
<!--基于springBoot容器测试-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>然后，配置配置文件:

测试:
通过浏览器直接测试转发(所以只能测试get请求),
url为: http://localhost/TEMPLATE-SERVICE/test/test
访问结果: null2018-07-05T22:53:44.009
但是如果url为: http://localhost/TEMPLATE-SERVICE/test/test?test=tristanTest
访问结果为: tristanTest2018-07-05T22:55:36.695至此配置中心、简单网关，注册、发现、转发、访问、映射参数就ok了，更多的过几天再写
