-Examples of go-for-apache-dubbo

+Examples of dubbo-go

 

-## dubbo

+## What does this contain

 

-#### Build by these command

+* helloworld

+

+    A simplest example. It contain 'go-client', 'go-server', 'java-server' of dubbo protocol. 

+

+* general

+

+    A general example. It had validated zookeeper registry and different parameter lists of service. 

+  And it has a comprehensive testing with dubbo/jsonrpc protocol. You can refer to it to create your first complete dubbo-go project.

+

+* generic

+

+    A generic reference example. It show how to use generic reference of dubbo-go.

+

+* configcenter

+

+    Some examples of different config center. There is only one -- zookeeper at present.

+

+## How to build and run

+

+> Take `helloworld` as an example

 

 java server

+

 ```bash

-cd dubbo/java-server

+cd helloworld/dubbo/java-server

 sh build.sh

-```

 

-java client

-```bash

-cd dubbo/java-client

-sh build.sh

-```

-

-go server

-

-* sh ./assembly/\[os]/\[environment].sh

-```bash

-cd dubbo/go-server

-# $ARCH = [linux, mac, windows] and $ENV = [dev, release, test]

-sh ./assembly/$ARCH/$ENV.sh

-```

-

-go client

-```bash

-cd dubbo/go-client

-# $ARCH = [linux, mac, windows] and $ENV = [dev, release, test]

-sh ./assembly/$ARCH/$ENV.sh

-```

-

-#### Run by these command:

-

-java server

-```bash

-cd dubbo/java-server/target

+cd ./target

 tar -zxvf user-info-server-0.2.0-assembly.tar.gz

 cd ./user-info-server-0.2.0

 sh ./bin/server.sh start

 ```

 

 java client

+

 ```bash

-cd dubbo/java-client/target

+cd helloworld/dubbo/java-client

+sh build.sh

+

+cd ./target

 tar -zxvf user-info-client-0.2.0-assembly.tar.gz

 cd ./user-info-client-0.2.0

 sh ./bin/server.sh start

 ```

 

 go server

+

+* $ARCH = [linux, mac, windows] and $ENV = [dev, release, test]

+

 ```bash

-cd dubbo/go-server/target/linux/user_info_server-0.3.1-20190517-0930-release

-#conf suffix appoint config file, 

-#such as server_zookeeper.yml when "sh ./bin/load.sh start is zookeeper", 

-#default server.yml

-sh ./bin/load.sh start [conf suffix]

+cd helloworld/dubbo/go-server

+sh ./assembly/$ARCH/$ENV.sh

+

+cd ./target/linux/user_info_server-0.3.1-20190517-0930-release

+# $SUFFIX is a suffix of config file,

+# such as server_zookeeper.yml when $SUFFIX is "zookeeper", 

+# if $SUFFIX = "", default server.yml

+sh ./bin/load.sh start $SUFFIX

 ```

 

 go client

+

+* $ARCH = [linux, mac, windows] and $ENV = [dev, release, test]

+

 ```bash

-cd dubbo/go-client/target/linux/user_info_client-0.3.1-20190517-0921-release

+cd helloworld/dubbo/go-client

+sh ./assembly/$ARCH/$ENV.sh

+

+cd ./target/linux/user_info_client-0.3.1-20190517-0921-release

 # $SUFFIX is a suffix of config file,

 # such as client_zookeeper.yml when $SUFFIX = zookeeper", 

 # if $SUFFIX = "", config file is client.yml

 sh ./bin/load_user_info_client.sh start $SUFFIX

 ```
