spring boot +dubbo+zookeeper
dubbo是一个分布式服务框架,致力于提供高性能和透明化的RPC远程服务调用方案,以及SOA服务治理方案。
结合本公司的开发也是用的dubbo这款优秀的框架,加上 最近工作重心的。所以对于dubbo的学习已经是迫在眉睫了。
在中秋假期,抽空实战了一把基于spring boot +dubbo+zookeeper 。其中也遇到了 很多的坑。
在这里记录一下。
我们看下dubbo的官网。http://dubbo.apache.org/en-us/ 。这里不在做赘述。
我们开始上手去实战一个初步的demo。用实战的角度去学习他。
在官网上也给我们了例子。
我们按照官网去实现它
首先 我们去搭建zookeeper。之所以选择zookeeper 我感觉还是资料多吧。
我们去下载zookeeper 然后启动就可以。
我这里用的是服务模式启动的。所以我在项目中用的 是3000的端口
我们去常见一个通用的api
1 2 3 4 5 6 7 8 9 10 11 12 13 | package com.example.demo; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class DemoApplication { public static void main(String[] args) { SpringApplication.run(DemoApplication. class , args); } } |
配置文件
1 2 3 | spring: application: name: interface |
我们去创建provider
pom.xml
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 | <?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 . 8 .RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.studay.leizi</groupId> <artifactId>leiziuser-server</artifactId> <version> 0.0 . 1 -SNAPSHOT</version> <name>leiziuser-server</name> <description>Demo project for Spring Boot</description> <properties> <java.version> 1.8 </java.version> </properties> <dependencies> <!-- Spring Boot dependencies --> <dependency> <groupId>com.alibaba.boot</groupId> <artifactId>dubbo-spring-boot-starter</artifactId> <version> 0.2 . 0 </version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> </dependency> <dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo-spring-boot-starter</artifactId> </dependency> <!-- Zookeeper dependencies --> <dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo-dependencies-zookeeper</artifactId> <version> 2.7 . 3 </version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version> 2.6 . 4 </version> <scope>compile</scope> <exclusions> <exclusion> <artifactId>spring</artifactId> <groupId>org.springframework</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>com.example</groupId> <artifactId>demo</artifactId> <version> 0.0 . 1 -SNAPSHOT</version> <scope>compile</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version> 2.1 . 0 .RELEASE</version> <executions> <execution> <goals> <goal>repackage</goal> </goals> </execution> </executions> </plugin> </plugins> </build> </project> |
实现方法
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | package com.studay.leizi.leiziuserserver.imp; import com.alibaba.dubbo.config.annotation.Service; import com.example.demo.service.DemoService; import org.springframework.beans.factory.annotation.Value; @Service public class DefaultDemoService implements DemoService { @Value ( "dubbo-auto-configuration-provider-demo" ) private String serviceName; public String sayHello(String name) { return String.format( "Hello, %s" , name); } } |
application.yml配置
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | spring: application: name: dubbo-registry-zookeeper-consumer-sample dubbo: registry: address: zookeeper: //127.0.0.1:3000 protocol: zookeeper id: my-registry protocol: name: dubbo port: 12345 id: dubbo status: server application: id: cusss name: cusss scan: basePackages: com.studay.leizi.leiziuserserver server: port: 8081 |
这个时候我们去启动。
启动成功,我们去创建服务消费方
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 | package com.styday.leiziapi.connec; import com.alibaba.dubbo.config.annotation.Reference; import com.alibaba.dubbo.config.annotation.Service; import com.example.demo.service.DemoService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; @Service @Component public class Demoe implements DemoService { @Reference DemoService demoService; @Override public String sayHello(String name) { return demoService.sayHello(name); } } |
为了方便我们查看调用是否成功,我们编写controller
package com.styday.leiziapi.connter; import com.styday.leiziapi.connec.Demoe; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.*; @RestController("/home") public class Consned { @Autowired Demoe demoe; @GetMapping("/getPayInfo") public String say(@RequestParam("name") String name) { return demoe.sayHello(name); } }
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | application.yml配置<br>spring: application: name: consumer dubbo: registry: address: zookeeper: //127.0.0.1:3000 protocol: name: dubbo port: 2081 id: dubbo application: id: cusss name: cusss scan: basePackages: com.styday.leiziapi.connec.Demoe server: port: 9999 |
启动完毕后, 启动。
、
我们可以用dubbo管理后台,去看服务的注册。下载地址 https://github.com/apache/dubbo/tree/2.5.x、
mvn clean package -Dmaven.test.skip=true
然后 放在Tomcat启动。
配置下
webapps\dubbo-admin-2.6.0\WEB-INF\dubbo.properties
然后启动后登陆就可以
这样就可以在管理后台查看我们的服务了。
