a good maven settings.xml article

https://www.cnblogs.com/jingmoxukong/p/6050172.html

till now, we have achieved the first step.(we assume readers already have maven environments)

generate odl project skeleton

mvn archetype:generate 
-DarchetypeGroupId=org.opendaylight.controller # project organizers exclusive identifier
-DarchetypeArtifactId=opendaylight-startup-archetype 
-DarchetypeRepository=https://nexus.opendaylight.org/content/repositories/public 
-DarchetypeVersion=1.3.2-Carbon 
-DgroupId=org.hut.hello 
-DartifactId=hello 
-DclassPrefix=Hello 
-Dcopyright=cmyhhxx

complie odl project skeleton

get into the project root path

mvn clean install 
-DskipTests 
-Dmaven.javadoc.skip=true 
-Dcheckstyle.skip=true

import the project into idea

get into the project root path

mvn idea:idea

open the .ipr file in idea,you can code in idea

edit the yang code

get into the following path

module hello {
    yang-version 1;
    namespace "urn:opendaylight:params:xml:ns:yang:hello";
    prefix "hello";

    rpc hello-world {
        input {
            leaf name {
                type string;
            }
        }
        output {
            leaf greeting {
                type string;
            }
        }
    }
}

compile the project and edit HelloProvider.java

get into the /api path

mvn clean install -DskipTests -Dmaven.javadoc.skip=true -Dcheckstyle.skip=true

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;
    }

    /**
     * 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");
    }

    @Override
    public Future<rpcresult<helloworldoutput>> helloWorld(HelloWorldInput input) {
        HelloWorldOutputBuilder h1 = new HelloWorldOutputBuilder();
        h1.setGreeting("hhhhhh"+input.getName());
        return RpcResultBuilder.success(h1.build()).buildFuture();
    }
}

register odl-rpc-implments into impl-buleprint.xml

compile the code

get into the /impl path

mvn clean install -DskipTests -Dmaven.javadoc.skip=true -Dcheckstyle.skip=true

get into the project root path

mvn clean install -DskipTests -Dmaven.javadoc.skip=true -Dcheckstyle.skip=true

test the hello project

cd /${your_project_home}/karaf/target/assembly/bin
./karaf

test from the apidoc

http://${your_host_ip}:8181/apidoc/explorer/index.html

test from a REST client
- choose postman or insomnia to send restful api

post url:
http://${your_odlserver_ip}:8181/restconf/operations/hello:hello-world

how to solve the problem java.lang.NumberFormatException: For input string: "0x100" if you met

vim /etc/profile

add the follwing into the end of the profile

export TERM=xterm-color
