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图片说明图片说明,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。

搭建zookeeper +dubbo +ssm遇到的问题

环境是我自己搭建的 我运行了页面 后台也不报错 就是一直在重复这句话2017-03-12 23:31:06,293 [localhost-startStop-1-SendThread(服务器地址:2181)] [org.apache.zookeeper.ClientCnxn]-[DEBUG] Got ping response for sessionid: 0x15ac2c6190b0008 after 2ms 请问这是怎么回事,zookeeper 我是搭建在本机虚拟机中的linux下的3.4.6 eclipse 中maven 中的jar 包是3.4.7,会是版本的问题么?求解答

SSM Dubbo 集成 Shiro 自定义Realm 注入 SysUserMapper 失败

先说下大概框架 SpringMVC Spring Mybatis 集成Dubbo,现在引入 shiro 服务端 配置 spring-mybatis.xml spring-service.xml 文件 消费端 配置 spring-mvc.xml 文件 当前 shiro.xml 配置文件 配置在了 消费端 。(服务端 ,消费端 都配置过 ,配置在服务端 ,页面拦截失效)。 spring-service.xml : ``` <context:component-scan base-package="com.artmall.manager.service"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> ``` spring-mvc.xml : ``` <!-- 扫描带注解的包 --> <context:component-scan base-package="com.artmall.manager"> <context:include-filter type="aspectj" expression="com.artmall.manager.common.aspect"/> <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> ``` # 出现问题: 自定义 Realm 的时候 引入 SysUserMapper , 服务端启动的时候 报错,Error creating bean with name 'userRealm': Could not autowire field :SysUserMapper。也就是说 SysUserMapper 注入是失败的 。 ** 理解**: shiro的自定义realm的认证阶段属于filter,当时的spring bean还没有读取进来。 见上配置文件 **服务端** 在启动的时候就已经 扫描 service了。 疑问的是 消费端 再启动的时候为什么 还会报这样的错。不知道是我理解的还不够到位还是什么 配置上有问题 希望有知道的朋友多多指点下 非常感谢。

150讲轻松搞定Python网络爬虫

【为什么学爬虫?】 &nbsp; &nbsp; &nbsp; &nbsp;1、爬虫入手容易,但是深入较难,如何写出高效率的爬虫,如何写出灵活性高可扩展的爬虫都是一项技术活。另外在爬虫过程中,经常容易遇到被反爬虫,比如字体反爬、IP识别、验证码等,如何层层攻克难点拿到想要的数据,这门课程,你都能学到! &nbsp; &nbsp; &nbsp; &nbsp;2、如果是作为一个其他行业的开发者,比如app开发,web开发,学习爬虫能让你加强对技术的认知,能够开发出更加安全的软件和网站 【课程设计】 一个完整的爬虫程序,无论大小,总体来说可以分成三个步骤,分别是: 网络请求:模拟浏览器的行为从网上抓取数据。 数据解析:将请求下来的数据进行过滤,提取我们想要的数据。 数据存储:将提取到的数据存储到硬盘或者内存中。比如用mysql数据库或者redis等。 那么本课程也是按照这几个步骤循序渐进的进行讲解,带领学生完整的掌握每个步骤的技术。另外,因为爬虫的多样性,在爬取的过程中可能会发生被反爬、效率低下等。因此我们又增加了两个章节用来提高爬虫程序的灵活性,分别是: 爬虫进阶:包括IP代理,多线程爬虫,图形验证码识别、JS加密解密、动态网页爬虫、字体反爬识别等。 Scrapy和分布式爬虫:Scrapy框架、Scrapy-redis组件、分布式爬虫等。 通过爬虫进阶的知识点我们能应付大量的反爬网站,而Scrapy框架作为一个专业的爬虫框架,使用他可以快速提高我们编写爬虫程序的效率和速度。另外如果一台机器不能满足你的需求,我们可以用分布式爬虫让多台机器帮助你快速爬取数据。 &nbsp; 从基础爬虫到商业化应用爬虫,本套课程满足您的所有需求! 【课程服务】 专属付费社群+每周三讨论会+1v1答疑

系列课程主要分为3大阶段:(1)首先掌握计算机视觉必备算法原理,结合Opencv进行学习与练手,通过实际视项目进行案例应用展示。(2)进军当下最火的深度学习进行视觉任务实战,掌握深度学习中必备算法原理与网络模型架构。(3)结合经典深度学习框架与实战项目进行实战,基于真实数据集展开业务分析与建模实战。整体风格通俗易懂,项目驱动学习与就业面试。 建议同学们按照下列顺序来进行学习:1.Python入门视频课程 2.Opencv计算机视觉实战(Python版) 3.深度学习框架-PyTorch实战/人工智能框架实战精讲:Keras项目 4.Python-深度学习-物体检测实战 5.后续实战课程按照自己喜好选择就可以

三个项目玩转深度学习(附1G源码)

从事大数据与人工智能开发与实践约十年,钱老师亲自见证了大数据行业的发展与人工智能的从冷到热。事实证明,计算机技术的发展,算力突破,海量数据,机器人技术等,开启了第四次工业革命的序章。深度学习图像分类一直是人工智能的经典任务,是智慧零售、安防、无人驾驶等机器视觉应用领域的核心技术之一,掌握图像分类技术是机器视觉学习的重中之重。针对现有线上学习的特点与实际需求,我们开发了人工智能案例实战系列课程。打造:以项目案例实践为驱动的课程学习方式,覆盖了智能零售,智慧交通等常见领域,通过基础学习、项目案例实践、社群答疑,三维立体的方式,打造最好的学习效果。

微信小程序开发实战之番茄时钟开发

微信小程序番茄时钟视频教程,本课程将带着各位学员开发一个小程序初级实战类项目,针对只看过官方文档而又无从下手的开发者来说,可以作为一个较好的练手项目,对于有小程序开发经验的开发者而言,可以更好加深对小程序各类组件和API 的理解,为更深层次高难度的项目做铺垫。

面试了一个 31 岁程序员,让我有所触动,30岁以上的程序员该何去何从?

最近面试了一个31岁8年经验的程序猿,让我有点感慨,大龄程序猿该何去何从。

用verilog HDL语言编写的秒表

在秒表设计中,分模块书写。用在七段数码管上显示。输入频率是1KHZ.可以显示百分秒,秒,分。如要显示小时,只需修改leds里的代码和主模块代码。改程序以通过硬件电路验证。完全正确。
