jdk8配置dubbo2.5.4

来源：互联网发布：手机c语言编程软件ios 编辑：程序博客网时间：2024/06/03 23:38

由于喜欢尝鲜，于是在Java9出来以后就马上把jdk换成了jdk1.9，结果最近刚学dubbo的时候一直都配置不成功，于是退回jdk1.8。一下就是配置dubbo的过程

安装Zookeeper

下载Zookeeper，然后把conf目录下的zoo.sample.cfg 改为 zoo.cfg
修改zoo.cfg，将dataDir修改为指定目录
tickTime=2000 initLimit=10 syncLimit=5 dataDir=/home/eros/data/zookeeper clientPort=2181 maxClientCnxns=60

安装tomcat

下载dubbo-admin包

如果是使用jdk8的话，可以在网上下载别人已经修改好的包，jdk1.8-dubbo-admin
下载完成后将war包放在tomcat的webapps目录下

启动Zookeeper服务器

sudo ./zkServer.sh start

启动tomcat

sudo ./startup.sh

访问http://localhost:8080/ 观察是否启动成功

在浏览器输入http://localhost:8080/dubbo-admin-2.5.4/，用户名和密码都是root

在Common模块中定义所有要暴露的接口

public interface IService {    int calculate(int x,int y);}

启动Server

dubbo.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd        http://code.alibabatech.com/schema/dubbo http://code.alibabatech.com/schema/dubbo/dubbo.xsd">    <bean id="providerImpl" class="org.eros.dubbo.server.service.ProviderServiceImpl"/>    <!-- 用dubbo协议在19091端口暴露服务 -->    <dubbo:protocol name="dubbo" port="19091"/>    <!-- 使用zookeeper注册中心暴露服务地址 -->    <dubbo:registry address="zookeeper://127.0.0.1:2181"/>    <!-- 提供方应用信息，用于计算依赖关系 -->    <dubbo:application name="ProviderService"/>    <dubbo:service interface="org.eros.dubbo.common.entity.IService" ref="providerImpl" timeout="100000"/></beans>

Spring配置类

@Configuration@ComponentScan@ImportResource("classpath:dubbo.xml")@EnableAspectJAutoProxypublic class Configure {}

接口的具体实现

public class ProviderServiceImpl implements IService{    @Override    public int calculate(int x, int y) {        return x+y;    }}

import java.io.IOException;public class Main {    private static final Logger logger= LogManager.getLogger(Main.class);    public static void main(String[] args) {        AnnotationConfigApplicationContext context=new AnnotationConfigApplicationContext(Configure.class);        context.start();        logger.debug("提供者服务已注册成功!");        try {            System.in.read();        } catch (IOException e) {            e.printStackTrace();        }    }}
