OpenDaylight开发环境搭建
作者：互联网
安装环境：Ubuntu18.04
一、安装依赖
1. 安装JDK：
sudo apt update sudo apt install openjdk-8-jdk-headless
选择默认的 JDK：
~$ sudo update-alternatives --config java There are 2 choices for the alternative java (providing /usr/bin/java). Selection Path Priority Status ------------------------------------------------------------ * 0 /usr/lib/jvm/java-11-openjdk-amd64/bin/java 1111 auto mode 1 /usr/lib/jvm/java-11-openjdk-amd64/bin/java 1111 manual mode 2 /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java 1081 manual mode Press <enter> to keep the current choice[*], or type selection number: 2 ~$ java -version
设置 JAVA_HOME:
echo JAVA_HOME=export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 >> ~/.bashrc source ~/.bashrc
2. 安装 maven：
sudo apt install maven
mvn -v
3. 安装 Sublime-Text3：（可选）
wget -qO - https://download.sublimetext.com/sublimehq-pub.gpg | sudo apt-key add - sudo apt-get install apt-transport-https echo "deb https://download.sublimetext.com/ apt/stable/" | sudo tee /etc/apt/sources.list.d/sublime-text.list sudo apt-get update sudo apt-get install sublime-text
二、搭建 ODL 代码框架
1. 获取配置 mvn 的 setting.xml：
~$ mkdir .m2
~$ wget -q -O - https://raw.githubusercontent.com/opendaylight/odlparent/master/settings.xml > ~/.m2/settings.xml
如果无法下载，则可以拷贝以下内容：
<?xml version="1.0" encoding="UTF-8"?>

2. 生成 odl 代码框架：
~$ mvn archetype:generate -DarchetypeGroupId=org.opendaylight.controller -DarchetypeArtifactId=opendaylight-startup-archetype -DarchetypeVersion=1.3.0-Carbon
Define value for property 'groupId': org.opendaylight.hello
Define value for property 'artifactId': hello
[INFO] Using property: version = 0.1.0-SNAPSHOT
Define value for property 'package' org.opendaylight.hello: :
Define value for property 'classPrefix' Hello: :
Define value for property 'copyright': ming
[INFO] Using property: copyrightYear = 2017
Confirm properties configuration:
groupId: org.opendaylight.hello
artifactId: hello
version: 0.1.0-SNAPSHOT
package: org.opendaylight.hello
classPrefix: Hello
copyright: ming
copyrightYear: 2017
Y: : y
3. 编译：
~$ cd hello/ ~/hello$ mvn clean install -DskipTests -Dmaven.javadoc.skip=true -Dcheckstyle.skip=true
4. 启动 odl 控制器：
~/hello$ cd karaf/target/assembly/bin
~/hello/karaf/target/assembly/bin$ ./karaf
opendaylight-user@root> feature:list | grep hello
5. Web 界面登录：
访问：http://127.0.0.1:8181/index.html 用户名密码都是 admin 。
三、RPC 实现
1. 编写、编译 yang 文件：
文件：~/hello/api/src/main/yang/hello.yang
module hello {
yang-version 1;
namespace "urn:opendaylight:params:xml:ns:yang:hello";
prefix "hello";
revision "2015-01-05" {
description "Initial revision of hello model";
}
rpc hello-world {
input {
leaf name {
type string;
}
}
output {
leaf greeting {
type string;
}
}
}
}
编译：（生成 RPC 定义等内容）
~/hello/api$ mvn clean install -DskipTests -Dmaven.javadoc.skip=true -Dcheckstyle.skip=true
2. 编写 impl-blueprint.xml文件：
注册 RPC。
文件：~/hello/impl/src/main/resources/org/opendaylight/blueprint/impl-blueprint.xml
<?xml version="1.0" encoding="UTF-8"?>
<!-- vi: set et smarttab sw=4 tabstop=4: -->

<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0"
xmlns:odl="http://opendaylight.org/xmlns/blueprint/v1.0.0"
odl:use-default-for-reference-types="true">
<reference id="dataBroker"
interface="org.opendaylight.controller.md.sal.binding.api.DataBroker"
odl:type="default" />
<bean id="provider"
class="org.opendaylight.hello.impl.HelloProvider"
init-method="init" destroy-method="close">
<argument ref="dataBroker" />
</bean>
<odl:rpc-implementation ref="provider"/>
</blueprint>
3. 实现 RPC 处理函数：
文件：~/hello/impl/src/main/java/org/opendaylight/hello/impl/HelloProvider.java
package org.opendaylight.hello.impl;
import org.opendaylight.controller.md.sal.binding.api.DataBroker;
import org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.hello.rev150105.HelloService;
import org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.hello.rev150105.HelloWorldInput;
import org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.hello.rev150105.HelloWorldOutput;
import org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.hello.rev150105.HelloWorldOutputBuilder;
import org.opendaylight.yangtools.yang.common.RpcResult;
import org.opendaylight.yangtools.yang.common.RpcResultBuilder;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.util.concurrent.Future;
public class HelloProvider implements HelloService {
private static final Logger LOG = LoggerFactory.getLogger(HelloProvider.class);
private final DataBroker dataBroker;
public HelloProvider(final DataBroker dataBroker) {
this.dataBroker = dataBroker;
}
@Override
public Future<RpcResult<HelloWorldOutput>> helloWorld(HelloWorldInput input) {
HelloWorldOutputBuilder helloBuilder = new HelloWorldOutputBuilder();
helloBuilder.setGreeting("Hello " + input.getName());
return RpcResultBuilder.success(helloBuilder.build()).buildFuture();
}
/**
* Method called when the blueprint container is created.
*/
public void init() {
LOG.info("HelloProvider Session Initiated");
}
/**
* Method called when the blueprint container is destroyed.
*/
public void close() {
LOG.info("HelloProvider Closed");
}
}
~/hello$ mvn clean install -DskipTests -Dmaven.javadoc.skip=true -Dcheckstyle.skip=true
4. 启动 odl：
~/hello/karaf/target/assembly/bin$ ./karaf
5. 查看、测试 API：
打开：http://localhost:8181/apidoc/explorer/index.html
点击：hello(2015-01-05) -> post /operations/hello:hello-world
在参数部分输入：
{
"input": {
"name": "SDN"
}
}
点击：Try it out!
