spring boot +motan+zookeeper整合，jdk1.8+idea开发环境
由于换了公司，公司用的是motan-RPC框架，所以就自己建了一个demo测试一下，有不足之处还请谅解，在网上搜了很多资料，motan+spring boot的整合还是比较少的，所以也耗时了几个小时。废话不多说，直接上干货。
首先是zookeeper的安装，详见我的另一篇博客（https://blog.csdn.net/qq_27394485/article/details/85098947），这里就不赘述。
一、server端：
idea项目整体目录
motan依赖：

0.2.1
com.weibo
motan-transport-netty
0.2.1
slf4j-log4j12

motan-springsupport
0.2.1

log4j
com.weibo
motan-registry-zookeeper
0.2.1
slf4j-log4j12
org.slf4j
log4j
log4j
api 暴露服务，server是spring boot 实现
下面上详细代码：
HelloService：
/**
*
*/
public interface HelloService {
void say(String name);
}HelloServiceImpl:
public class HelloServiceImpl implements HelloService {
@Override
public void say(String name) {
System.out.println("hello "+name);
}
}MotandemoServerApplication.java
import com.weibo.api.motan.common.MotanConstants;
import com.weibo.api.motan.util.MotanSwitcherUtil;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ImportResource;
@SpringBootApplication
@ImportResource(locations={"classpath*:motan-server.xml"})
public class MotandemoServerApplication {
public static void main(String[] args) {
SpringApplication.run(MotandemoServerApplication.class, args);
MotanSwitcherUtil.setSwitcherValue(MotanConstants.REGISTRY_HEARTBEAT_SWITCHER, true);
}
}接下来是服务提供者的xml文件，即motan-server.xml，里面配置了一些RPC调用的信息以及注册信息等，玩过dubbo的应该很熟悉。
二、client端
client是个我以前写的springbootdemo，我在里面加了一个motan-client.xml文件和包等即可完成，比较简单，但是容易出错，有人说是motan的bug，一会上错误信息。
controller类
@RestController
@EnableAutoConfiguration
public class HelloSpringBootApplication {
@Autowired
private ExceptionService exceptionService;
@Autowired
private UserService userService;
@Autowired
private HelloService helloService;
@RequestMapping("hello")
public Object helloWorld(@RequestParam(value = "age",required = false) int age) throws Exception{
int result=exceptionService.exceptionTest(age);
helloService.say("刘先生");
return new Result(200,"success",result);
//return "hello world! This is springboot demo!";
}
motan-client.xml
springboot启动类
@SpringBootApplication
@MapperScan("com.example.springbootdemo.dao")
@ImportResource(locations={"classpath*:motan-client.xml"})
public class SpringbootdemoApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootdemoApplication.class, args);
MotanSwitcherUtil.setSwitcherValue(MotanConstants.REGISTRY_HEARTBEAT_SWITCHER, true);
}
}
三、运行阶段
启动zookeeper服务端后，先启动motan-server端，具体启动信息如下：
2018-12-22 21:18:37.879 INFO 14444 --- [ main] org.apache.zookeeper.ZooKeeper : Initiating client connection, connectString=127.0.0.1:2181 sessionTimeout=60000 watcher=org.I0Itec.zkclient.ZkClient@3549bca9

可以看到一直有心跳信息打印。
接下来是客户端启动：

接下来是在浏览器中请求：
可以看到server端的信息也在控制台打印出来了
至此motan+spring boot +zookeeper跑起来了。
忘了说client启动的时候报的错了，其中一个是我在pom.xml关掉了log等相关包后，motan的zookeeper包说找不到log相关包，所以我就打开了一个就正常了。另外一个是，client在启动的时候会报500错误，连接不上zookeeper，但是我多试几次后又好了，不知道是什么问题，还有待研究。
写的比较潦草，还望见谅，其中也有一些地方没搞懂原理，在学习后会更新的。
