Hello Spring Cloud Alibaba（六）之使用dubbo

dubbo介绍dubbo使用建立公共接口api模块服务提供者服务消费者启动 说明

dubbo介绍

dubbo是一款高性能、轻量级的开源Java RPC框架，它提供了三大核心能力：面向接口的远程方法调用，智能容错和负载均衡，以及服务自动注册和发现。

建立公共接口api模块

服务提供者

引入依赖 引入dubbo，common-api依赖，完整依赖如下： <?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>top.musuixin</groupId> <artifactId>hello-alibaba</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <groupId>top.musuixin</groupId> <artifactId>hello-alibaba-provider</artifactId> <version>0.0.1-SNAPSHOT</version> <name>hello-alibaba-provider</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <!-- 表明这是一个spring-cloud应用--> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-alibaba-nacos-config</artifactId> </dependency> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-alibaba-nacos-discovery</artifactId> </dependency> <!-- dubbo--> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-dubbo</artifactId> </dependency> <dependency> <groupId>top.musuixin</groupId> <artifactId>hello-alibaba-common-api</artifactId> <!-- 版本可以在通用依赖中设置--> <version>0.0.1-SNAPSHOT</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project> 配置dubbo 配置如下： spring: cloud: nacos: config: server-addr: 192.168.0.100:8848 file-extension: yaml discovery: server-addr: 192.168.0.100:8848 application: name: hello-alibaba-provider server: port: 8030 dubbo: protocol: # 协议名称 name: dubbo #服务端口 port: 7000 registry: # nacos注册中心 address: nacos://192.168.0.100:8848 application: name: hello-alibaba-provider 建立包类 开启dubbo

服务消费者

引入依赖，与提供者一样配置文件 spring: cloud: nacos: config: server-addr: 192.168.0.100:8848 file-extension: yaml discovery: server-addr: 192.168.0.100:8848 sentinel: transport: #服务端的ip:port dashboard: 192.168.0.100:8858 #这里要配置客户端的ip client-ip: 192.168.0.1 application: name: hello-alibaba-consumer server: port: 8000 dubbo: protocol: name: dubbo port: 7010 registry: # nacos注册中心 address: nacos://192.168.0.100:8848 application: name: hello-alibaba-consumer 建立包类

启动

先启动服务提供者、后启动消费者
