springmvc+dubbo 启动过程几点问题,求解答
springmvc中引入dubbo的配置文件后,在启动web容器的时候会加载dubbo的配置文件 并由dubbo的解释器进行解析xml配置,装配到spring容器,问题来了,问题1:我并没有启动dubbo的服务,dubbo是怎么启动的?问题2:dubbo的启动是通过com.alibaba.dubbo.container.Main中的main方法启动的,源码中是在main方法中又启动了一个SpringContainer,这里的Main是谁来调用的?问题3:以上过程中是不是启动了两spring容器?
Dubbo服务部署到服务器上,从本地访问服务器上的服务访问不通
<br> ### /----------原问题----------/(问题已经解决,答案在后文) <br> <br> 如题,项目使用的是dubbo+nacos,在本地上启动provider端和customer端,可以正常访问。 (provider和customer端同时部署到服务器上,也可以正常访问) 但是,把provider端部署到linux服务器上,再从本地启动customer端就访问不了,一直显示超时(两者分开部署,访问显示超时)... ``` org.apache.dubbo.remoting.TimeoutException: Waiting server-side response timeout by scan timer. start time: 2019-10-21 11:32:02.027, end time: 2019-10-21 11:32:12.047, client elapsed: 1 ms, server elapsed: 10018 ms, timeout: 10000 ms, request: Request [id=5, version=2.0.2, twoway=true, event=false, broken=false, data=RpcInvocation [methodName=sayHello, parameterTypes=[], arguments=[], attachments={path=com.braisedpanda.suanfa.service.TestService, activelimit_filter_start_time=1571628722027, interface=com.braisedpanda.suanfa.service.TestService, version=1.0.0, timeout=10000}]], channel: /172.215.1.27:50876 -> /172.17.0.2:20880 at org.apache.dubbo.remoting.exchange.support.DefaultFuture.doReceived(DefaultFuture.java:189) ~[dubbo-2.7.3.jar:2.7.3] at org.apache.dubbo.remoting.exchange.support.DefaultFuture.received(DefaultFuture.java:153) ~[dubbo-2.7.3.jar:2.7.3] at org.apache.dubbo.remoting.exchange.support.DefaultFuture$TimeoutCheckTask.run(DefaultFuture.java:252) ~[dubbo-2.7.3.jar:2.7.3] at org.apache.dubbo.common.timer.HashedWheelTimer$HashedWheelTimeout.expire(HashedWheelTimer.java:648) ~[dubbo-2.7.3.jar:2.7.3] at org.apache.dubbo.common.timer.HashedWheelTimer$HashedWheelBucket.expireTimeouts(HashedWheelTimer.java:727) ~[dubbo-2.7.3.jar:2.7.3] at org.apache.dubbo.common.timer.HashedWheelTimer$Worker.run(HashedWheelTimer.java:449) ~[dubbo-2.7.3.jar:2.7.3] at java.lang.Thread.run(Thread.java:748) [na:1.8.0_211] ``` 网页报错:![图片说明](https://img-ask.csdn.net/upload/201910/21/1571629077_503413.png) 配置: ![图片说明](https://img-ask.csdn.net/upload/201910/21/1571629427_901327.png) ![图片说明](https://img-ask.csdn.net/upload/201910/21/1571629436_736567.png) 部署linux:![图片说明](https://img-ask.csdn.net/upload/201910/21/1571629510_364799.png) 网上各种方法都试过了,折腾一周了还是不行, 设置timeout时间,关闭Linux防火墙,删除了连接数据的代码,直到后来我甚至怀疑服务器有问题,又租了台服务器测试还是不行....... 快要崩溃了... 希望有大佬能指出问题... <br> <br> <br> /----------以下是问题解决方案----------/ ####先说下问题出现的原因: dubbo服务部署在linux服务器上时,它默认使用的是linux系统的内网,对外暴露的是内网的地址,这就导致我本地项目访问该服务器服务时,访问不通,出现超时错误。这就解释了为什么服务端和消费端同时部署在本地,或者同时部署在服务器上时,可以畅通无阻的访问了。 ![图片说明](https://img-ask.csdn.net/upload/201910/23/1571810544_540718.png) 如图片所示,我原先注册的服务全是172开头的内网,本地访问不通。后来修改了之后,dubbo对外暴露外网,可以顺利访问。 至于如何让dubbo在linux部署时暴露外网服务,网上有很多教程,说什么修改linux hosts主机名和公网ip,修改linux DNS地址,甚至还有禁用linux网卡.. 这些我都试过了,全都没用~ 每个人的情况都不一样,可能对有些人有用 ####我的解决办法: 1、 我在项目配置中添加了: spring.cloud.nacos.discovery.ip=39.98.131.xxx (这个ip地址,是你要部署服务器的公网地址。 比如你要部署到公网地址为39.98.131.588这台服务器上, 那上面就写39.98.131.588) 2、docker 运行镜像时,添加 DUBBO_IP_TO_REGISTRY语句 ``` docker run -d -e DUBBO_IP_TO_REGISTRY=39.98.131.xxx -e DUBBO_PORT_TO_REGISTRY=20880 -p 20880:20880 --name xxx xxxx(镜像名称) ``` 这下,这个问题终于解决了,真的坑,折腾我好久了,麻蛋~ 下面贴上我的配置,仅供参考,方面同样被这个问题困扰的小伙伴早点脱困 bootstrap.yml ``` ##应用名称 spring: main: allow-bean-definition-overriding: true # profiles: # active: public cloud: nacos: discovery: enabled: true register-enabled: true server-addr: ${spring.cloud.nacos.config.server-addr} namespace: ${spring.cloud.nacos.config.namespace} config: server-addr: 47.98.135.xxx:8848 group: provider namespace: c229ab10-2e39-4444-be97-048b3a5ef49d file-extension: yaml ``` <br> application.properties ``` spring.application.name=balance-suanfa-provider dubbo.application.name=balance-suanfa-provider dubbo.scan.base-packages=com.braisedpanda.suanfa.service dubbo.protocol.name=dubbo dubbo.protocol.port=20880 #这个本地测试就注释吧,部署到服务器上时,根据服务器公网填写 #spring.cloud.nacos.discovery.ip=39.98.131.xxx dubbo.registry.address=nacos://47.98.135.xxx:8848 dubbo.provider.loadbalance=myRoundRobin #dubbo.provider.actives=8 #dubbo.provider.executes=8 dubbo.provider.dispatcher=message dubbo.provider.threadpool=cached dubbo.provider.timeout=50000 dubbo.provider.delay=-1 dubbo.application.dump-directory=/tmp dubbo.provider.cluster=failfast dubbo.consumer.check=false dubbo.registry.check=false ``` 附上两篇有用的参考连接: https://juejin.im/post/5b2072016fb9a01e2d704431 https://www.jianshu.com/p/7c29a24a917d

dubbo服务端有返回,客户端接收到null的问题【紧急】
### 现象 服务端日志已经显示返回结果,结果为自定义对象 格式如下: ``` AcctQueryFacadeImpl.acctBalanceQuery00, resp=AcctBalanceQuery00Resp[uid=1355739,acctStatus=N,createTime=Fri Mar 04 21:36:31 CST 2016,updateTime=Wed Apr 20 19:52:24 CST 2016,acctId=4985191,balance=0,frozenBalance=0,withdrawBalance=0,respDesc=成功,respCode=000000], time=2ms ``` 客户端接收到的对象为null 该现象并不是必现, - 现象1:调用acctBalanceQuery00方法一天有几十万次,目前出现问题的仅3例 - 现象2:有2条失败数据,重试之后,1条成功,1条仍然失败 - 现象3:很多业务调用acctBalanceQuery00方法,但目前只有1个业务出问题,这些业务入参基本一样,(此现象也许是巧合) - 现象4:用dubbo telnet invoke acctBalanceQuery00方法,有结果返回,用出问题的数据invoke,也有结果返回,所有机器都试过 ### 环境 jdk1.8 dubbo版本 2.5.3 服务端4台,客户端10台左右 dubbo服务端配置如下: ``` <dubbo:application name="xxx" owner="yy"/> <dubbo:registry protocol="zookeeper" client="zkclient" address="${dubbo.zk.servers}" group="${dubbo.zk.group}"></dubbo:registry> <dubbo:protocol name="dubbo" port="20909"></dubbo:protocol> <dubbo:provider retries="0" timeout="6000"></dubbo:provider> <dubbo:service interface="xxxx" ref="xxx"></dubbo:service> ``` dubbo消费端配置: ``` <dubbo:application name="${application.name}" owner="${dubbo.application.owner}"/> <dubbo:registry protocol="zookeeper" client="zkclient" address="${dubbo.zk.servers}" group="${dubbo.zk.group}"></dubbo:registry> <dubbo:protocol name="dubbo" port="${dubbo.protocol.port}"></dubbo:protocol> <dubbo:monitor address="${dubbo.monitor.address}"></dubbo:monitor> <dubbo:consumer retries="0" timeout="6000" check="false"></dubbo:consumer> ```
非spring应用使用dubbo的问题?
我们的程序不是spring开发的,所以用了dubbo的api模式,把微服务应用中几个需要互相调用提供服务的接口和实现类作为提供者注册到dubbo,同时在需要调用服务的微服务应用中作为消费者引用和调用,这能够正常工作,同时在dubbo-admin界面中也能够看到注册的服务提供者和消费者,以及服务调用的统计。 但是我有一个问题,我们部署了nginx用于应用转发,根据url中的服务名(即微服务应用的id)部分,转发到不同的微服务应用,微服务可能会部署多个实例,也用nginx实现负载均衡。加入dubbo后,只有少数几个需要暴露给其它服务调用的服务基于dubbo的服务治理来管理,其它从浏览器和app发起的请求,直接走nginx转发微服务了,根本不走dubbo,因为遵循高内聚低耦合原则拆分微服务且尽量规避跨服务事务,所以微服务间的rpc调用非常少,这种情况下dubbo只管理很少的rpc调用,分布式治理的意义在哪里呢(分布式治理应该是管理所有的分布式调用包括负载均衡吧?)?难道我应该把所有的服务都注册到dubbo,浏览器访问也访问dubbo吗? 或者我应该问,如何更合理地使用dubbo呢? 另外,基于srping开发的应用,是否是把所有controller都注册到dubbo呢?无论这个controller是否会被其它微服务调用?基于Spring开发的应用,浏览器访问也经过Dubbo吗?
一个dubbo配置超时的问题。求助。
最近有个dubbo的项目,有超时的问题。看了下配置文件 dubbo:reference 里配置的时间300秒 dubbo:registry 里也配置了一个超时时间3秒 各种超时问题 另一个环境两个的时间是反过来配置的,目前没发现这类问题。 想问下大神们,这两个地方配置的timeout作用分别是什么?
关于Dubbo配置的问题~ spring整合Dubbo出现问题。

dubbo启动报错连接服务超时
dubbo启动会检查所有提供者,有的能调通,有的由于服务器设置不能调通。怎样设置只要有能调通的就不报错,而不是遇到调不通的就报错。求各位大神解答。。。。。。。。。。
dubbo 提供端如何配置才能限制服务端的ip?
在控制台可以根据服务一个一个配置,但是服务太多了,想请教一下,有没有可以直接在提供端一次性配置的?

dubbo工程可以部署在多个服务器上吗
我知道dubbo可以用来解耦 将业务分为多个模块 通过ZK实现web工程对后端工程的调用也可以后端工程之间调用 。如果我有多个dubbo服务,他们之间有调用关系,这样可以部署在不同服务器上吗?
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。。
Dubbo中的TargetChildListener这个类的定义在哪,为什么找不到
AbstractZookeeperClient<TargetChildListener> 这个TargetChildListener类的定义,具体在什么位置
maven项目配置dubbo报错,能找到相应的jar

Python爬虫精简步骤1 获取数据
爬虫的工作分为四步: 1.获取数据。爬虫程序会根据我们提供的网址,向服务器发起请求,然后返回数据。 2.解析数据。爬虫程序会把服务器返回的数据解析成我们能读懂的格式。 3.提取数据。爬虫程序再从中提取出我们需要的数据。 4.储存数据。爬虫程序把这些有用的数据保存起来,便于你日后的使用和分析。 这一篇的内容就是:获取数据。 首先,我们将会利用一个强大的库——requests来获取数据。 在电脑上安装
