用springcloud创建分布式框架

创建Maven项目

1. groupId：公司名+项目名，com.wsh.springcloudFramework
2. artifactId: 项目名+模块名称， springcloudframework

一.搭建注册中心

• 添加pom.xml，注意版本问题，这个应该是最新的了

<groupId>com.wsh.springcloudFramework</groupId>
    <artifactId>springcloudframework</artifactId>
    <version>1.0-SNAPSHOT</version>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.2.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
    </properties>
    <dependencies>
        <dependency>
            <!--eureka server -->
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>

        <dependency>
            <!-- spring boot test-->
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
        </dependency>
    </dependencies>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Finchley.M7</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

    <repositories>
        <repository>
            <id>spring-milestones</id>
            <name>Spring Milestones</name>
            <url>https://repo.spring.io/milestone</url>
            <snapshots>
            <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>

• 增加application.yml，idea直接创建file文件，然后更改后序

#端口号
server:
  port: 8888
#eureka配置
eureka:
  instance:
    #注册中心ip地址
    hostname: localhost
  client:
    #是否注册到eureka
    registerWithEureka: false
    #是否检测服务信息
    fetchRegistry: false
    #注册地址
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

• 创建运行类

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

@SpringBootApplication
@EnableEurekaServer
public class mainApplication {

    public static void main(String[] args) {
        SpringApplication.run(mainApplication.class, args);
    }
}

• 然后访问http://localhost:8888/，就可以看到效果了
