Necessary dependencies

JDK 1.6+ [1]

Default dependencies

use mvn dependency:tree > dep.log command to analysis,Dubbo default depends on the following 3rd party libraries:

[INFO] +- com.alibaba:dubbo:jar:2.5.9-SNAPSHOT:compile
[INFO] |  +- org.springframework:spring-context:jar:4.3.10.RELEASE:compile
[INFO] |  +- org.javassist:javassist:jar:3.21.0-GA:compile
[INFO] |  \- org.jboss.netty:netty:jar:3.2.5.Final:compile

All dependencies here are selected for the default configuration of the Dubbo, which are based on stability and performance considerations.

  • javassist.jar [2]: if <dubbo:provider proxy="jdk" /> or <dubbo:consumer proxy="jdk" />,or <dubbo:application compiler="jdk" />, is not required.
  • spring-context.jar [3]: If you are using ServiceConfig and ReferenceConfig API calls, is not required.
  • netty.jar [4]: if <dubbo:protocol server="mina"/> or <dubbo:protocol server="grizzly"/>,Then change to mina.jar or grizzly.jar. If <protocol name="rmi"/>, is not required.

  1. In theory, Dubbo only depend on JDK, not depend on any 3rd party libs, you can finish logic by useing JDK. ↩︎

  3. Configuration parsing ↩︎

  4. Network transmission ↩︎
