dubbo zookeeper配置中心

dubbo中有没有方法可以获取到配置中心拿到的所有配置? 或者说与spring中的定义的properties配置合并, 自定义优先级。 当zookeeper配置发生改变时有没有办法进行监听? 不想自己去连接zk获取或者进行监听。 非常感谢。。

关于ssm+dubbo+zookeeper搭建时提供者的问题

搭了一个ssm+dubbo+zookeeper的框架,webserver是tomcat,碰到个奇怪的问题,在spring-dubbo.xml配置里给了端口20880,发布dubbo-service项目,dubbo admin里出现了定义的服务,但是提供者清单里却有2个ip端口一致的提供者,再次发布dubbo-service项目,tomcat日志报Address aready bind in use这个错,所以又改了一下端口20881,结果如下图![图片说明](https://img-ask.csdn.net/upload/201702/24/1487937262_295726.png)![图片说明](https://img-ask.csdn.net/upload/201702/24/1487937342_158045.png)![图片说明](https://img-ask.csdn.net/upload/201702/24/1487937401_692271.png),可以看到又出现了2个ip端口一致的提供者,而且停止其中的一个另一个也停止,查询进程20880 和20881两个端口都是由一个tomcat的进程占用的,我是在tomcat里发布了两个war,一个是dubbo2.8.4的war一个是我自己的dubbo-service项目的war,有谁知道怎么回事么?为什么会有两个ip端口一致的提供者,明明是一个服务,而且20880和20881两个端口除非关闭tomcat,否则一直被占用。

dubbo如何正确关闭Spring容器

查看dubbo文档,Dubbo是通过JDK的ShutdownHook来完成优雅停机的: http://dubbo.io/User+Guide-zh.htm#UserGuide-zh-%E4%BC%98%E9%9B%85%E5%81%9C%E6%9C%BA 但能实现优雅停机的前提是,在启动时,需要指定参数-Ddubbo.shutdown.hook=true: com.alibaba.dubbo.container.Main.main源码: ``` if ("true".equals(System.getProperty(SHUTDOWN_HOOK_KEY))) { Runtime.getRuntime().addShutdownHook(new Thread() { public void run() { for (Container container : containers) { try { container.stop(); logger.info("Dubbo " + container.getClass().getSimpleName() + " stopped!"); } catch (Throwable t) { logger.error(t.getMessage(), t); } synchronized (Main.class) { running = false; Main.class.notify(); } } } }); } ``` 我的问题是,如果没有指定-Ddubbo.shutdown.hook=true而实际中采用kill PID(不是kill -9 PID)的方式来停止应用,Spring容器能正常关闭吗,Spring的bean能不能正确销毁?

如何解决重复加载Spring配置文件

菜鸟有一问题请教: 任务描述:我采用struts1.2+hibernate3.0+spring2.0搭建框架,开发项目。在使用dwr技术实现检查机构名是否存在功能。功 能实现在业务层,由于要调用数据层的方法,我使用spring的依赖注入方式,将数据层实现类注入到数据层的接口对象。 问题描述:在web.xml中配置dwr方式一: <servlet> <servlet-name>dwr</servlet-name> <servlet-class> org.directwebremoting.servlet.DwrServlet </servlet-class> <init-param> <param-name>debug</param-name> <param-value>true</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>dwr</servlet-name> <url-pattern>/dwr/*</url-pattern> </servlet-mapping> 这样配置,无法实现注入,数据层接口对象为null; 在web.xml中配置dwr方式二: 在以上配置上加入以下: <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> 这种方式spring配置文件会重复加载,因为在strut配置文件中添加对spring的支持是采用插件方式。 我的问题:怎样解决重复加载spring配置文件?

Dubbo采用RMI协议时怎样设置servicePort(服务端口)

如果不用dubbo,直接用spring暴露RMI的时候需要配置2个端口。其中一个是registerPort,即注册端口; 还有一个是servicePort即服务端口,用来传输数据用。例子如下: <bean id="isms2001RMIService" class="com.newera.mc.isms.rmi.impl.ISMS2001RMIServiceImpl" scope="prototype" /> <bean id="isms2001SrvExporter" class="org.springframework.remoting.rmi.RmiServiceExporter"> <property name="service" ref="isms2001RMIService" /> <property name="serviceName" value="isms2001RMIService" /> <property name="serviceInterface" value="com.newera.mc.isms.rmi.ISMS2001RMIService" /> <property name="registryPort" value="${rmi.registryPort}" /> <property name="servicePort" value="${rmi.servicePort}" /> </bean> 因为内网中设置了防火墙,必须把各端口都确定下来,否则随机端口是不允许访问的。 但在dubbo中怎样设置这个servicePort呢?
