dubbo 环境搭建

初次体验，做个总结和记录,主要在引入依赖包的时候遇到问题多。jdk环境是1.8
添加依赖，这个依赖比较少了

最好先在maven的setting.xml中设置自己的本地maven库的地址。这样在后续打包发布之后consumer才可以拿到jar。

添加一个properties文件,添加一些

dubbo.reference.check=false
dubbo.registry.client=curator
dubbo.application.name=provider1
dubbo.application.owner=debug

dubbo.protocol.name=dubbo
dubbo.protocol.dubbo.port=20903

dubbo.protocol.name=rest
dubbo.protocol.rest.port=9013
dubbo.protocol.rest.server=tomcat

添加一个xml配置文件

<?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-4.3.xsd
        http://code.alibabatech.com/schema/dubbo
        http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
    <!--发布出去的dubbo服务类所在包的注解-->
    <dubbo:annotation package="com.zah.dubbostudy2.service.dubbo" />

    <!--注册中心zookeeper配置信息-->
    <dubbo:registry address="zookeeper://127.0.0.1:2181" />
    <!--支持两种协议的调用：rpc-dubbo协议；http协议-rest api-url调用-->
    <dubbo:protocol name="rest" threads="500" contextpath="v1" server="tomcat" accepts="500" port="9013"/>
    <dubbo:protocol name="dubbo" port="20903"/>
    <!--消费方信息配置-->
    <dubbo:application name="consumer1" owner="debug" organization="dubbox"/>
</beans>

网上有的xml，注解的不能够被引用。这个没有问题，都是测试通过的。
然后配置一下消费者方的文件，properties文件都差不多，就是端口号和名称改一下

dubbo.reference.check=false
dubbo.registry.client=curator
dubbo.application.name=provider2
dubbo.application.owner=debug

添加配置文件xml

<?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-4.3.xsd
        http://code.alibabatech.com/schema/dubbo
        http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
    <!--发布出去的dubbo服务类所在包的注解-->
    <dubbo:annotation package="com.nn.dubbostudy3.server.service.dubbo" />

    <!--注册中心zookeeper配置信息-->
    <dubbo:registry address="zookeeper://127.0.0.1:2181" />
    <!--支持两种协议的调用：rpc-dubbo协议；http协议-rest api-url调用-->
    <dubbo:protocol name="rest" threads="500" contextpath="v1" server="tomcat" accepts="500" port="9014"/>
    <dubbo:protocol name="dubbo" port="20904"/>

    <!--消费方信息配置-->
    <dubbo:application name="consumer2" owner="debug" organization="dubbox"/>
    <!--deploy content-->
    <dubbo:reference id="dubboItemService" interface="com.nn.project.service.IDubboItemService"
       protocol="dubbo" version="1.0" timeout="20000"/>
</beans>

其它问题就比较容易解决了。

dubbo 的控制台搭建
官网http://dubbo.apache.org/zh-cn/docs/admin/introduction.html
按照操作使用maven构建。
如果发现tomcat端口被占用，windows下
netstat -ano|findstr 8080
taskkill /pid 55565 /f
