SpringBoot怎么搭建Dubbo项目实现斐波那契第n项

    step1 新建项目

    方法1:直接在IDEA里新建如图:

    方法2:在start.spring.io新建

    可能有的小朋友已经发现了,名列前茅种方式的Server URL就是第二个的网站,都是一样的

    要新建两个项目,名列前茅个项目如上图所示,第二个项目只需要将provider改为consumer

    其余不变,解压后通过IDEA打开

    step2 新建需要的包和接口以及实现类

    provider 项目结构:

    consumer 项目结构:

    请注意,两个ServiceAPI在项目中的的所在位置,或者说包名要严格一致,否则后续会出问题

    如果不一致,可以按照如下方式按需进行更改

    xsd放到指定目录下:

    C:Users用户名.lemminxcachehttpcode.alibabatech.comschemadubbo

    文件:dubbo.xsd

    step3 在两个项目的resource下新建配置文件

    需要新建的名字为:spring-dubbo.xml

    provider的该配置文件中写入:

    <?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"       xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd	   http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">    <!-- dubbo应用名称 -->    <dubbo:application name="springboot-buddo-provider"/>    <!-- 发布者 dubbo协议  -->    <dubbo:protocol name="dubbo" port="20881"/>    <!-- 定义bean -->    <bean id="providerImpl" class="com.springdubbo.demo.springbootdubbo.apiImpl.ProviderImpl"/>    <!-- dubbo服务 发布者发布服务  需要暴露的服务接口 -->    <dubbo:service interface="com.springdubbo.demo.springbootdubbo.ServiceAPI" ref="providerImpl"                   registry="N/A"/></beans>

    consumer的该配置文件内写入:

    <?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"       xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsd	   http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">    <!-- dubbo应用名称 -->    <dubbo:application name="springboot-buddo-consumer"/>    <!-- 远程服务调用代理 -->    <dubbo:reference id="consumerImpl"                     interface="com.springdubbo.demo.springbootdubbo.ServiceAPI"                     url="dubbo://localhost:20881" /></beans>

    step4 代码编写

    导入依赖

    在两个项目的pom.xml下均添加依赖:

    <dependency>	<groupId>com.alibaba.spring.boot</groupId>	<artifactId>dubbo-spring-boot-starter</artifactId>	<version>2.0.0</version></dependency>

    provider

    ProviderImpl

    Service注解一定不要忘记加,而且一定要是dubbo的Service

    package com.springdubbo.demo.springbootdubbo.apiImpl;import com.alibaba.dubbo.config.annotation.Service;import com.springdubbo.demo.springbootdubbo.ServiceAPI;/** * @author wuyt * @data 2022/6/11 * @apiNote */@Servicepublic class ProviderImpl implements ServiceAPI {    public String getMessage(String message) {        return "springboot-dubbo-provider  =>>>>>" + message;    }    public String getTheFeibN(int n) {        //斐波那契数列第n项的实现逻辑    }}

    ServiceAPI

    package com.springdubbo.demo.springbootdubbo;/** * @author wuyt * @data 2022/6/11 * @apiNote */public interface ServiceAPI {    public String getMessage(String message);    public String getTheFeibN(int n);}

    SpringbootDubboApplication

    一定要加上ImportResource注解

    package com.springdubbo.demo.springbootdubbo;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.annotation.ImportResource;@SpringBootApplication@ImportResource("classpath:spring-dubbo.xml")public class SpringbootDubboApplication {    public static void main(String[] args) {        SpringApplication.run(SpringbootDubboApplication.class, args);    }}

    consumer

    ServiceAPI

    package com.springdubbo.demo.springbootdubbo;/** * @author wuyt * @data 2022/6/11 * @apiNote */public interface ServiceAPI {    public String getMessage(String message);    public String getTheFeibN(int n);}

    SpringbootDubboApplication

    package com.springdubbo.demo.springbootdubbo;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.ConfigurableApplicationContext;import org.springframework.context.annotation.ImportResource;@SpringBootApplication@ImportResource("classpath:spring-dubbo.xml")public class SpringbootDubboApplication {	public static void main(String[] args) {		ConfigurableApplicationContext count = SpringApplication.run(SpringbootDubboApplication.class, args);		ServiceAPI impl = (ServiceAPI)count.getBean("consumerImpl");//		System.out.println(impl.getMessage("Hello dubbo"));		System.out.println(impl.getTheFeibN(10));	}}

    端口冲突更改

    可以修改provider或者是consumer其中任意一个的端口号

    这里修改consumer运行的端口号:

    step5 运行

    首先运行provider,然后运行consumer

    结果:
