SpringCloud项目搭建步骤

SpringCloud项目搭建步骤

springCloud五大核心组件

五大核心组件如下:

服务发现——Netflix Eureka客户端

负载均衡——Netflix Ribbon

断路器——Netflix Hystrix

服务网关——Netflix Zuul

分布式配置——Spring Cloud Config

一、搭建eureka客户端

1.新建一个SpringBoot项目
2.pom文件(springcloud版本需要与springboot版本对应。详情点击)

<?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>

        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    
    <groupId>eureka-server</groupId>
    <artifactId>eureka-server</artifactId>
    <version>1.0-SNAPSHOT</version>
    <name>eureka-server</name>

    <properties>
        <java.version>1.8</java.version>
        <spring-cloud.version>2020.0.5</spring-cloud.version>
    </properties>


    <dependencies>

            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</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>

</project>

3.yml文件配置

server:
  port: 8761
eureka:
  instance:
    hostname: localhost
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka

4.启动类

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {

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

二、导入项目(搭建项目)

1.项目pom文件(非全部,对应拷贝)

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.4.2</version>
</parent>
 <properties>
 		<spring-cloud.version>2020.0.5</spring-cloud.version>
  </properties>
    <dependencies>
  		<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
    <dependencies>
   	<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

2.yml文件

server:
  port: 8762
  max-http-header-size: 10240
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
spring:
  application:
    name: xxx #注册中心名称,必填。
