odl-boron-sr3之hello rpc

环境安装，请看这里。
之前的文章，已经建立了hello，详情看这里。
现在做一个hello的rpc。官方文档看这里。

环境：odl-boron-sr3和mvn和java

ps：本篇文章只有过程，没有细致讲解（因为我也不太懂呀）
1.添加rpc api：
编辑api/src/main/yang/hello.yang，修改为下面代码（这里新增了输入和输出）

    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 {        input {            leaf name {                type string;            }        }        output {            leaf greeting {                type string;            }        }    }}

2.进到api文件夹执行mvn clean install
3.实现rpc api：
进入impl/src/main/java/org/bupt/siwind/hello/impl，然后新建文件HelloImpl.java并填入下面代码。

再编辑HelloProvider.java,修改为下面代码（init函数启动时会调用hello rpc）：

3.注册rpc api：
编辑impl/src/main/resources/org/opendaylight/blueprint下的impl-blueprint.xml，修改为下面代码：

4.到impl文件夹中执行mvn clean install
5.到hello文件夹中执行mvn clean install
6.运行./karaf/target/assembly/bin/karaf
执行log:display | grep Hello输出没有error，就说明成功了。
7.测试rest，用postman或相关软件。
url：http://127.0.0.1:8181/restconf/operations/hello:hello
method:post
basic auth:admin admin
body:

{"input": {    "name": "Songqiu"  }}
