springboot 整合dubbox
1, 没了,,,
2, 安装zookeeper
可见: http://www.cnblogs.com/wenbronk/p/6636926.html
2.1 下载:
wget http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.8/
解压:
tar -zxf zookeeper-3.4.8.tar.gz
修改配置文件:
cd zookeeper-3.4.8/conf
cp zoo_sample.cfg zoo.cfg # zookeeper 默认是用../conf/zoo.cfg 如果没有这个文件则报错
vim zoo.cfg
其他, 能启动就行吧
cd zookeeper-3.4.8/bin
./start.sh start #启动zookeeper 关闭: ./start.sh stop
我的zookeeper是安装在docker上的, 安装方式可见: http://www.cnblogs.com/wenbronk/p/6438492.html
3, maven工程
|--dubbo-prent 父工程(pom)
|
|_____dubbo-cosumer 消费者(war)
|
|_____duboo-provide 生产者(pom)
|
|_____interface 消费者和生产者都依赖这个, 一个接口, 实现rpc(jar)
|
|_____service 实际的rpc调用的方法(war)
其中interface 被 dubbo-consumer和service所依赖
4, parent
parent主要用来统一管理使用的, 在其pom中进行jar包的统一依赖管理
pom.xml配置:
"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">

5, dubbo-provide, 这儿没什么用, 管理生产者和接口, 实际中还可以用来依赖统一的工具包等
pom.xml中没啥东西
"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">

6, interface:
用来rpc调用的接口, 只有一个类:
TestService.java
package com.wenbronk.dubbo.service;
public interface TestService {
public String test();
}
7, service
服务的生产者:
pom.xml中用来依赖包
"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">

发布dubbo服务, 在application.properties中加入以下配置:
server.port=8081
# Dubbo 消费者
spring.dubbo.application.name=provider
spring.dubbo.registry.address=zookeeper://192.168.50.202:2181
spring.dubbo.protocol.name=dubbo
spring.dubbo.protocol.port=20880
spring.dubbo.scan=com.wenbronk.dubbo
注意配置 scan的扫描路径
App.java
package com.wenbronk.dubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class App {
public static void main(String[] args) throws Exception {
SpringApplication.run(App.class, args);
}
}
TestServiceImpl.java
package com.wenbronk.dubbo.service.impl;
import com.alibaba.dubbo.config.annotation.Service;
import com.wenbronk.dubbo.service.TestService;
@Service(version="1.0.0")
public class TestServiceImpl implements TestService {
@Override
public String test() {
System.out.println("success");
return "finally, i am coming";
}
}
8, 最后, 是cosumer
pom.xml中配置, 同service中一样,
application.properties
## 避免和 server 工程端口冲突
server.port=8080
## Dubbo 服务消费者配置
spring.dubbo.application.name=consumer
spring.dubbo.registry.address=zookeeper://192.168.50.202:2181
spring.dubbo.scan=com.wenbronk.dubbo
App.java 同service一样
TestController.java
package com.wenbronk.dubbo.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.alibaba.dubbo.config.annotation.Reference;
import com.wenbronk.dubbo.service.TestService;
@RestController
public class TestController {
@Reference(version="1.0.0")
private TestService testService;
@RequestMapping("/abc")
public String test() {
System.out.println("controller.sucess");
testService.test();
return "success";
}
}
最初因为说dubbo-start不支持新的spring了, 所以下载了当当的dubbox自己编译, 后来发现, 还是可以用的
附: dubbox编译
dubbo, 阿里不维护了, 当当继续开源: 因为没有发布在仓库, 所以自己编译
git clone https://git.oschina.net/smarti/spring-boot-mybatis-sample.git
然后跳过test进行编译, 可以发布在本地仓库中
mvn install -Dmaven.test.skip=true
听说用注解的话, 不支持事物, 还没遇到, 遇到在更新
