SpringBoot 整合 dubbo xml实现代码示例
昨天发布了注解方式,有人给我发了邮件希望能出一版本xml格式的,本来12点前能搞定的但是电脑稍微出了问题,导致idea 疯狂奔溃,搞了很久废话不多说了,有错误之处望大家指出发我邮箱.
用dubbo肯定是多模块化了 所以我们先创建一个聚合项目
这是项目结构
Dubbo_demo 的pom 这个主要用来聚合业务模块用不做任何业务处理
<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.hzb</groupId> <artifactId>Dubbo_demo</artifactId> <version>0.0.1-SNAPSHOT</version> <!--我们这是多模块开发 所以这边要 变成 pom--> <packaging>pom</packaging> <!--系统模块--> <modules> <module>hzbdubbo-consumer</module> <module>hzbdubbo-provider</module> </modules> <!--配置文件属性--> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <java.version>1.8</java.version> </properties> </project>
然后按照上面的方法创建两个项目一个是 服务的提供者 和服务的消费者
提供者和消费者不懂的话点击这个连接了解一下http://dubbo.io/
服务提供者代码片段:
生成基本项目按第一个图片的去生成
代码结构: 由于是demo不按规范结构来看得懂就行
服务提供者pom :
<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.hzb.dubbo.provider</groupId> <artifactId>hzbdubbo-provider</artifactId> <packaging>jar</packaging> <name>hzbdubbo-provider</name> <description>Demo project for Spring Boot</description> <parent> <groupId>com.hzb</groupId> <artifactId>Dubbo_demo</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <version>1.5.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> <version>1.5.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <version>1.5.2.RELEASE</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>2.4.10</version> <exclusions> <exclusion> <artifactId>spring</artifactId> <groupId>org.springframework</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> <version>3.4.6</version> <exclusions> <exclusion> <artifactId>slf4j-log4j12</artifactId> <groupId>org.slf4j</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>com.github.sgroschupf</groupId> <artifactId>zkclient</artifactId> <version>0.1</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>1.5.2.RELEASE</version> </plugin> </plugins> </build> </project>
注意pom中 parent 对应的是什么和聚合pom进行关联
dubbo.xml中配置:
<?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/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd"> <!-- 配置可参考 http://dubbo.io/User+Guide-zh.htm --> <!-- 服务提供方应用名,用于计算依赖关系 --> <dubbo:application name="dubbo-provider" owner="dubbo-provider" /> <!-- 定义 zookeeper 注册中心地址及协议 --> <dubbo:registry protocol="zookeeper" address="127.0.0.1:2181" client="zkclient" /> <!-- 定义 Dubbo 协议名称及使用的端口,dubbo 协议缺省端口为 20880,如果配置为 -1 或者没有配置 port,则会分配一个没有被占用的端口 --> <dubbo:protocol name="dubbo" port="-1" /> <!-- 声明需要暴露的服务接口 --> <dubbo:service interface="com.hzb.dubbo.provider.DemoService" ref="demoService" timeout="10000" /> <!-- 和本地 bean 一样实现服务 --> <bean id="demoService" class="com.hzb.dubbo.provider.DemoServiceImpl" /> </beans>
这个想要了解配置的意思点击这个连接:http://dubbo.io/books/dubbo-user-book-en/英文版https://help.github.com/categories/github-pages-basics/
服务提供者启动类代码:
package com.hzb.dubbo.provider; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.ImportResource; @SpringBootApplication // 使用 dubbo.xml 配置 @ImportResource(value = {"classpath:dubbo.xml"}) public class DubboProviderApplication { public static void main(String[] args) { SpringApplication.run(DubboProviderApplication.class, args); System.out.println("服务提供者启动成功"); } }
服务 service接口代码:
业务实现代码:“
接下来就是服务消费者了:
项目结构:
消费者pom 也是要注意pom中和上面有哪些不一样 和 多了那个依赖
<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.hzb.dubbo.consumer</groupId> <artifactId>hzbdubbo-consumer</artifactId> <packaging>jar</packaging> <name>hzbdubbo-consumer</name> <description>Demo project for Spring Boot</description> <parent> <groupId>com.hzb</groupId> <artifactId>Dubbo_demo</artifactId> <version>0.0.1-SNAPSHOT</version> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <version>1.5.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</artifactId> <version>1.5.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <version>1.5.2.RELEASE</version> <scope>test</scope> </dependency> <!-- 阿里巴巴提供的格式化依赖 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.1.41</version> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>dubbo</artifactId> <version>2.4.10</version> <exclusions> <exclusion> <artifactId>spring</artifactId> <groupId>org.springframework</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>org.apache.zookeeper</groupId> <artifactId>zookeeper</artifactId> <version>3.4.6</version> <exclusions> <exclusion> <artifactId>slf4j-log4j12</artifactId> <groupId>org.slf4j</groupId> </exclusion> </exclusions> </dependency> <dependency> <groupId>com.github.sgroschupf</groupId> <artifactId>zkclient</artifactId> <version>0.1</version> </dependency> <dependency> <groupId>com.hzb.dubbo.provider</groupId> <artifactId>hzbdubbo-provider</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <version>1.5.2.RELEASE</version> </plugin> </plugins> </build> </project>
dubbo.xml配置:
启动类:
测试调用服务Controller
接下来就是先把服务提供者启动起来 然后在启动消费者
运行结果
