Play Spring boot integration Dubbo using spring boot and Dubbo integration, here I have tried to use annotations, the simple use of annotations to register the service is actually no problem, but when you involve the use of annotations in the service to refer to the transaction, injection of other objects, There will be some problems. So I decided to give up the annotations, using XML, which may be described here is Dubbo, but if the use of Dubbox, it is basically compatible. Next, we'll talk about using XML as a way to develop with spring boot. 1. Create a project to add dependencies in Pom.xml the project name is: (1) springboot-dubbo-provide (2) Springboot-dubbo-api (3) Springboot-dubbo-consume Springboot-dubbo-api project is mainly to put some service interface, used to provide consumers with. Springboot-dubbo-provide Engineering is used to provide services. Springboot-dubbo-consume works for consumers. Open Pom.xml in the Springboot-dubbo-provide project to add the following dependencies, complete the code as follows: [HTML] View plain copy 4.0.0 Com.chengli Springboot-dubbo-provide 0.0.1-snapshot Jar Springboot-dubbo-provide http://maven.apache.org org.springframework.boot spring-boot-starter-parent 1.4.3.RELEASE UTF-8 1.8 2.5.3 3.4.6 0.1 com.chengli springboot-dubbo-api 0.0.1-snapshot org.springframework.boot spring-boot-starter /dependency>!--Dubbo--> Com.alibaba Dubbo org.springframework spring ${com.al Ibaba.dubbo.version} org.apache.zookeeper zookeep Er ${org.apache.zookeeper.version} com.github.

Just define the interface implementation in the API. When using spring boot to integrate with Dubbo, it is important to note that you do not use the Devtools hot start provided by spring Boot, because Devtools provides two classloader, and the load policy issue causes an error and cannot be started. If hot loading is required in development, use the springloaded provided by spring. Interested friends can add groups to explore mutual learning:
