SpringCloud框架搭建+实际例子+讲解+系列二

上一节简单讲解了SpringCloud的一些东西和我要实现的功能，大致的思路框架。这一节我们将把核心流程展示如下。

一、创建maven父项目（负责整体项目的编译和打包功能，没有实际代码）

pom文件如下所示：

<?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>mymall-master</groupId>
    <artifactId>mymall-master</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>pom</packaging>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.3.5.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <modules>
        <module>common-moudle</module>
        <module>accountservice</module>
        <module>eurekaserver</module>
        <module>mallserviceApp</module>
    </modules>
</project>

二、创建子项目

（1）Eureka-Server 服务管制中心

pom文件如下：

<?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>
    <parent>
        <groupId>mymall-master</groupId>
        <artifactId>mymall-master</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>

    <groupId>eureka-server</groupId>
    <artifactId>eureka-server</artifactId>
    <version>1.0-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
        </dependency>
    </dependencies>
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Brixton.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
</project>

Application.class如下：

package com.application;

import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@EnableEurekaServer
@SpringBootApplication
public class Application {
    public static void main(String[] args){
        new SpringApplicationBuilder(Application.class).web(true).run(args);
    }
}

application-server1.properties-----application-server2.properties-----application-server3.properties文件如下:

spring.application.name=eureka-server
server.port=1111
eureka.instance.hostname=server1
eureka.client.serviceUrl.defaultZone=http://server2:1112/eureka/,http://server3:1113/eureka/

spring.application.name=eureka-server
server.port=1112
eureka.instance.hostname=server2
eureka.client.serviceUrl.defaultZone=http://server1:1111/eureka/,http://server3:1113/eureka/

spring.application.name=eureka-server
server.port=1113
eureka.instance.hostname=server3
eureka.client.serviceUrl.defaultZone=http://server1:1111/eureka/,http://server2:1112/eureka/

其中server1 、server2、server3的变量设置如下：（本人是win7）

win:C:\Windows\System32\drivers\etc\hosts文件中，添加：

127.0.0.1 server1

127.0.0.1 server2

127.0.0.1 server3

编译项目，启动服务管制中心，本例子是启动了三个端口的服务管制中心，代表了三台服务器：

java  - jar eureka-server-1.0-SNAPSHOT.jar --spring.profiles.active=server1

java  - jar eureka-server-1.0-SNAPSHOT.jar --spring.profiles.active=server2

java  - jar eureka-server-1.0-SNAPSHOT.jar --spring.profiles.active=server3
