此篇文章讲解在之前使用的nacos的基础上整合Gateway，之前整合的nacos项目不在赘述 环境准备 1、启动nacos 2、准备服务A启动后注册到注册中心nacos中
下面创建gateway 1、创建一个spring boot项目，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 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.15.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.mythical</groupId> <artifactId>rosefinch-gateway</artifactId> <version>0.0.1-SNAPSHOT</version> <name>gateway</name> <description>小程序网关</description> <properties> <java.version>1.8</java.version> <spring-cloud.version>Greenwich.SR1</spring-cloud.version> </properties> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-gateway</artifactId> </dependency> <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-alibaba-nacos-discovery</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</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> <!-- 整合springCloud Alibaba --> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-alibaba-dependencies</artifactId> <version>0.9.0.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> </plugin> </plugins> </build> </project>2、application.yml文件如下:
server: port: 8083 spring: application: name: gateway cloud: nacos: discovery: server-addr: localhost:8848 #指定 namespace,此id在nacos中创建一个命名空间即可生成，一定要与A服务中一致，不然gateway路由不到A服务 namespace: 4c6a61af-7019-4bda-a83b-e4ebb8edcdd4 #指定集群 cluster-name: NJ gateway: discovery: locator: #让gateway通过服务发现组件找到其他的微服务 enabled: true management: endpoints: web: exposure: include: '*' endpoint: health: show-details: always3、启动gateway服务
4、访问验证 rosefinch-web是A的服务名称 user/getAllUser是A的方法路径
http://127.0.0.1:8083/rosefinch-web/user/getAllUser 5、结果： 通过gateway访问到了A服务
这个只是实现了一下路由功能，后续会完善gateway的一些项目应用
