Springboot under the Dubbo, zookeeper combined use

Recent research on the Dubbo framework

Believe to see this blog, the foundation of Dubbo should have

Zookeeper set up a little detour, the configuration of all kinds of trouble, Mom's good annoying.

Just wanted to use Docker, but there was a simple concept for Docker.

Spent the night studying Docker and found it really useful.

Build a zookeeper and play it.

Here is a record of some of the pits encountered!

1, Springboot introduction of Dubbo configuration file

Search the internet for a bit, probably two ways

1. This is done by Classpathxmlapplicationcontext loading the XML to get contextual context start

1 @SpringBootApplication2 3  Public classwreserveapplication {4 5      Public Static voidMain (string[] args)throwsIOException, interruptedexception {6Classpathxmlapplicationcontext context =NewClasspathxmlapplicationcontext (Newstring[]{"Dubbo-provider.xml"});7 Context.start ();8System.in.read ();//Press any key to exit9     }Ten  One}

2. Load by @ImportResource ({"Classpath:dubbo-provider.xml"}).

1 @SpringBootApplication2@ImportResource ({"Classpath:dubbo-provider.xml" })3  Public classwreserveapplication {4 @Bean5      PublicCountdownlatch Closelatch () {6         return NewCountdownlatch (1);7     }8 9      Public Static voidMain (string[] args)throwsIOException, interruptedexception {TenConfigurableapplicationcontext context = Springapplication.run (wreserveapplication.class, args); OneCountdownlatch Closelatch = Context.getbean (countdownlatch.class); A closelatch.await (); -  -     } the  -}

2. Some problems needing attention in dubbo-provider.xml and Dubbo-consumer.xml

Dubbo-provider.xml

<?XML version= "1.0" encoding= "UTF-8"?><Beansxmlns= "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-2.5.xsd Http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd ">        <dubbo:applicationname= "Demo-provider"/>    <!--Use Multicast Registry Center to export service -    <Dubbo:registryAddress= "zookeeper://192.168.99.100:2181"/>    <!--Use Dubbo protocol to export service on port 20880 -    <Dubbo:protocolname= "Dubbo"Port= "20880"/>    <!--service implementation, as same as regular local bean -    <BeanID= "HelloService"class= "Com.zhyonk.service.Impl.HelloServiceImpl"/>    <!--Declare the service interface to be exported -    <Dubbo:serviceInterface= "Com.zhyonk.service.HelloService"ref= "HelloService"/>    </Beans>

Dubbo-consumer.xml

<?XML version= "1.0" encoding= "UTF-8"?><Beansxmlns= "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 ">    <dubbo:applicationname= "Wreserve-wechat"></dubbo:application>    <!--Zookeeper Registration Center -    <Dubbo:registryAddress= "zookeeper://192.168.99.100:2181"></Dubbo:registry>    <Dubbo:consumerCheck= "false"Timeout= "60000" />    <!--generate a remote service proxy that can be used like a local bean demoservice -    <dubbo:referenceID= "HelloService"Interface= "Com.zhyonk.wreserve.service.HelloService"Protocol= "Dubbo"Timeout= "15000" /></Beans>

1, consumers to access the provider,

<id= "HelloService"        interface= " Com.zhyonk.wreserve.service.HelloService "  protocol=" Dubbo "

    <!--service implementation, as same as regular local bean -    <BeanID= "HelloService"class= "Com.zhyonk.service.Impl.HelloServiceImpl"/>    <!--Declare the service interface to be exported -    <Dubbo:serviceInterface= "Com.zhyonk.service.HelloService"ref= "HelloService"/>

One of the interface must require the same path, or not correspond, the following situation will occur

Under normal circumstances, the dubbo-admin will show

2, if you do not have to build trouble, you can use the site to automatically generate http://start.dubbo.io/

We'll be here first, sleep.
