springcloud-eureka与gateway简易搭建过程_Java

eureka

spring cloud eureka主要负责实现微服务架构中的服务治理功能，简易搭建步骤为：

新建euereka-server项目

创建maven项目，在pom.xml中配置以下依赖信息：

<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>
    <java.version>1.8</java.version>
    <spring-cloud.version>greenwich.release</spring-cloud.version>
</properties>
<build>
    <plugins>
        <plugin>
            <groupid>org.springframework.boot</groupid>
            <artifactid>spring-boot-maven-plugin</artifactid>
        </plugin>
    </plugins>
</build>
<dependencies>
    <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>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencymanagement>

新建服务启动类

@enableeurekaserver
@springbootapplication
public class startapplication {
    public static void main(string args[]){
        springapplication.run(startapplication.class,args);
    }
}

配置相关属性

在application.properties中增加如下配置：

spring.application.name=eureka-server
server.port=8761
# 不向注册中心注册自己
eureka.client.register-with-eureka=false
# 不需要检索服务
eureka.client.fetch-registry=false
# 关闭保护机制，使服务正常退出，方便开发与调试
eureka.server.enableselfpreservation=false
eureka.client.service-url.defaultzone=http://*.*.226.80:8762/eureka/

启动服务

启动服务后，可通过eureka提供的web控制台查看服务注册状态

编写微服务进行注册测试

新建maven项目，在pom.xml中增加如下依赖：

<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>
    <java.version>1.8</java.version>
    <spring-cloud.version>greenwich.release</spring-cloud.version>
</properties>
<dependency>
    <groupid>org.springframework.boot</groupid>
    <artifactid>spring-boot-starter-web</artifactid>
</dependency>
<dependency>
    <groupid>org.springframework.cloud</groupid>
    <artifactid>spring-cloud-starter-netflix-eureka-client</artifactid>
</dependency>
<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>

在application.properties中增加如下配置：

eureka.client.register-with-eureka=true
eureka.client.fetchregistry=true
eureka.client.server.waittimeinmswhensyncempty=0
eureka.client.service-url.defaultzone=http://10.18.226.209:5054/eureka/
eureka.instance.prefer-ip-address=true
eureka.instance.instance-id=springcloud-test:5051

启动服务，可以看到已经成功注册到eureka上

至此eureka已经部署完成

springcloudgateway

springcloudgateway作为springcloud生态系中的网关，为微服务架构提供统一的路由管理，并且根据http请求进行相应的匹配、断言、过滤，其简易搭建方法如下：

新建gateway项目

新建maven项目，在pom.xml中增加如下依赖：

<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>
    <java.version>1.8</java.version>
    <spring-cloud.version>greenwich.release</spring-cloud.version>
</properties>
<dependency>
    <groupid>org.springframework.cloud</groupid>
    <artifactid>spring-cloud-starter-gateway</artifactid>
</dependency>
<dependency>
    <groupid>org.springframework.cloud</groupid>
    <artifactid>spring-cloud-starter-netflix-eureka-client</artifactid>
</dependency>
<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>

配置相关属性

在application.properties中增加如下配置：

spring.application.name=springcloud-gateway-test
server.port=5052
server.tomcat.uri-encoding=utf-8
###############################################################
#默认所有服务转发操作
spring.cloud.gateway.discovery.locator.enabled=true
#小写服务名
spring.cloud.gateway.discovery.locator.lower-case-service-id=true
