Erlang SDK Manual on Apache Dubbo

Quick Start

Mon, 01 Jan 0001 00:00:00 +0000

It is recommended to first define the interface jar using Java, and use the erlanalysis tool to parse Java interfaces into Erlang lib.

Import Dependency Libraries

Using the Rebar Build Tool.

Add dubblerl to your project’s rebar.config

{deps, [
 {dubboerl, {git, "https://github.com/apache/dubbo-erlang.git", {branch, "master"}}}
]}.

Using the `erlang.mk` Build Tool

To be added

Import Interface Libraries

Suppose the interface lib you exported is called dubbo_service.

If you didn’t upload your lib to your git repository, it is recommended that you copy the dubbo_service lib into the project’s apps directory.
If it is uploaded to your git repository, you can import it like this:

{deps, [
 {dubboerl, {git, "https://github.com/apache/dubbo-erlang.git", {branch, "master"}}},
 {dubbo_service,{git,"${INTERFACE_LIB_URL}",{branch,"master"}}} %% replace ${INTERFACE_LIB_URL} with your lib git repo URL
]}.

Consumer Configuration

Please reference Reference Config

Consumer Configuration

Mon, 01 Jan 0001 00:00:00 +0000

Basic Configuration

Consumer configurations need to be added to the sys.config file under the dubboerl application configuration.

{dubboerl,[
	%% other config ...
	{consumer,[
		{<<"interface fullname">>,[Option]},
		%% eg:
		{<<"org.apache.dubbo.erlang.sample.service.facade.UserOperator">>,[]},
	]}
]}

Option configuration items are to be added.

Provider Configuration

Mon, 01 Jan 0001 00:00:00 +0000

Basic Configuration

Provider configuration items need to be added to the sys.config file under the dubboerl application configuration item.

{dubboerl,[
	%% other config ...
	{provider,[
		{module_implements,interface_module,interface_fullname,[Options]},
		%% eg:
		{userOperator_impl,userOperator,<<"org.apache.dubbo.erlang.sample.service.facade.UserOperator">>,[Option]}
	]}
]}

ConfigName	Type	DefaultValue	Remarks
module_implements	atom()	-	The service implementation module name
interface_module	atom()	-	Interface module name converted from java jar
interface_fullname	binary()	-	Fully qualified name of the interface’s Java class

Option is to be added.

Serialization Configuration Options

Mon, 01 Jan 0001 00:00:00 +0000

Currently, this library only implements the dubbo:// communication protocol.

Two serialization methods are implemented: hessian and json.

Configuration Example

The serialization configuration needs to be added to the dubboerl application configuration in the sys.config file.

{dubboerl,[
	%% other config ...
	{protocol,hessian}
]}

ConfigName	Type	DefaultValue	Remarks
protocol	atom()	hessian	hessian,json
