Dependencies

Dubbo dependencies

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.

Optional dependencies

These dependencies needs to be added to project manually，when you need them.

  • netty-all 4.0.35.Final
  • mina: 1.1.7

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

  2. Bytecode generation ↩︎

  3. Configuration parsing ↩︎

  4. Network transmission ↩︎

  5. JAVAEE ↩︎ ↩︎ ↩︎ ↩︎
