This article is about the operation of spring | springboot integration dubbo. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's follow the editor to have a look.

Project background

Now domestic small and medium-sized companies, remote calls are basically dubbo, of course, knife companies are no exception, we used to use the version of dubbo 2.4.x, although it can also be used, but in the pursuit of new projects and new technologies, we updated to the version of dubbo 2.7.x

The previous integration mode of springboot integrated dubbo application

Introduce jar package of dubbo and zk

@ ImportResource ({"classpath*:dubbo/*.xml"}) public class Start extends SpringBootServletInitializer

The dubbo.properties content is as follows:

Dubbo.container=logback,springdubbo.application.name=dubbo-servicedubbo.registry.address=zookeeper://zookeeper.xxx.com:2181dubbo.log4j.file=logs/dubbo-service.logdubbo.log4j.level=WARNdubbo.protocol.port=20782dubbo.protocol.dispatcher=messagedubbo.protocol.threadpool=fixeddubbo.protocol.threads=200

And dubbo.provider.xml.

At this time, you should be able to see the application registered on dubbo-admin.

New way of integration

With the last wave of multi-module shelves built with gradle, today we add dubbo to it.

Official documents:

Https://github.com/apache/dubbo-spring-boot-project

First introduce related dependencies. Note here that dependencies are placed in the service layer, because it is the service layer that needs to provide dubbo services. Of course, to save trouble, you can also put it in business-impl, because we will call the dubbo interface of other projects, but strictly speaking, the application of basic service only takes data from its own database and returns it to the business application through the dubbo interface. Therefore, in the basic application, the dependency can only be referred to the service layer, and the business application can be directed directly to the business-impl layer.

Service providing layer

Implementation 'org.springframework.boot:spring-boot-starter'

TestImplementation 'org.springframework.boot:spring-boot-starter-test' compile group:' org.apache.dubbo', name: 'dubbo-spring-boot-starter', version:' 2.7.1 'compile (group:' org.apache.dubbo', name: 'dubbo-dependencies-zookeeper' Version: '2.7.2') {exclude group:'org.slf4j'} compile (' org.apache.dubbo:dubbo:2.7.2') {exclude group:' org.springframework' exclude group:' javax.servlet' exclude group:' log4j'}

Configure in application.properties:

Dubbo.application.name=forest-servicedubbo.registry.address=zookeeper://zookeeper.xxx.com:30038dubbo.protocol.name=dubbodubbo.protocol.port=21899dubbo.config-center.address=zookeeper://zookeeper.xxx.com:30038dubbo.metadata-report.address=zookeeper://zookeeper.xxx.com:30038dubbo.scan.base-packages=com.platform.market.service.impl

The directory structure of this era code is as follows:

Among them, on the implementation class, you need to add the following two comments:

@ Service@Componentpublic class ItemServiceImpl implements ItemService

Note that it is the service annotation in the dubbo package

Then we can see the service we started in dubbo-admin

Service consumption layer

It's very simple here. In a word, change the @ Autowire we wrote before to @ Reference in the dubbo package.

That's it.

You only need to quote the registered address in the configuration file.

Dubbo.application.name=xxxx-xxxxdubbo.registry.address=zookeeper://zookeeper.xxx.com:30038 above is the operation process of spring | springboot integrating dubbo. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article.
