spring+motan+zookeeper入門
一、vm centos中安裝zookeeper
在zookeeper根目錄新建data logs資料夾
新建並配置zoo.cfg
tickTime=2000
dataDir=/software/zookeeper-3.4.11/data
dataLogDir=/software/zookeeper-3.4.11/logs
clientPort=2181
initLimit=5
syncLimit=2
切換到bin目錄# ./zkServer.sh start啟動zookeeper 再# ./zkServer.sh status 檢視是否啟動成功
二、
idea新建maven專案 選擇webapp
完成後new module 同樣選中webapp 依賴
一個專案中的多個模組。
pom新增spring和motan依賴

spring-mvc.xml配置

api介面實現類
@MotanService
public class HelloWorldImpl implements HelloWorld
{
private Logger log = LoggerFactory.getLogger(getClass());
@Override
public String hello(String name) {
log.debug("hello,name");
return "hello,"+name;
}
}
motan優雅啟動(什麼鬼我也不知道 別人那看來的)
public class MotanServletContextListener implements ServletContextListener {
@Override
public void contextDestroyed(ServletContextEvent arg0) {
}
@Override
public void contextInitialized(ServletContextEvent event) {
//這個時候spring已經初始化完成,呼叫以下的類來調整motan狀態
MotanSwitcherUtil.setSwitcherValue(MotanConstants.REGISTRY_HEARTBEAT_SWITCHER, true);
}
}
main方法 用作測試 省去寫controller麻煩
public class Main
{
public static void main(String[] args)
{
@SuppressWarnings("unused")
ApplicationContext applicationContext = new ClassPathXmlApplicationContext(
new String[] {"classpath*:spring.xml"});
MotanSwitcherUtil.setSwitcherValue(MotanConstants.REGISTRY_HEARTBEAT_SWITCHER, true);
System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>server start...");
}
}
忘了web.xml
<?xml version="1.0" encoding="utf-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee"

>>>>>client模組
service
@Service
public class SayHello
{
@MotanReferer
private HelloWorld hello;
private Logger log = LoggerFactory.getLogger(getClass());
public String say(String name){
String result = hello.hello(name);
System.out.println(result);
log.debug(result);
return result;
}
}
main
public class Main
{
public static void main(String[] args) throws InterruptedException {
ApplicationContext ctx = new ClassPathXmlApplicationContext(new String[] {"classpath:spring.xml" });
SayHello service = (SayHello) ctx.getBean(SayHello.class);
for (int i = 0; i < 10; i++) {
service.say("motan" + i);
Thread.sleep(1000);
}
System.out.println(">>>>>>>>>>>motan demo is finish.");
System.exit(0);
}
}
別忘了修改zookeeper地址。
啟動發現失敗 不能註冊zookeeper
centos中關閉防火牆 #systemctl stop firewalld.service
新增log4j發現報錯資訊:session xxxx
首先檢查zookeeper是否啟動成功 ,然後修改連線退出時間在spring.xml中
<motan:registry regProtocol="zookeeper" name="registry" address="192.168.94.128:2181" connectTimeout="2000"/>
如果數值較小 則修改為100000
同時修改zookeeper中zoo.cfg引數 設定minSessionTimeout 和maxSessionTimeout 為100000和200000
重啟服務,重啟專案。
啟動成功!!
