本来是没问题的，可是我将mysql的包换了个版本（换回去还是一样），就开始报这个错了，不过在IDEA中没有报错。 俺解决了，是将JSTL包下的tld文件全部复制到了web-inf中，不知道有没有更优雅的解决办法？

项目的jar包和文件均没有错，通过maven和gitlab导入，在win系统下可运行；可是在mac系统下编译运行会报错，编译后打包文件在win系统下也会报相同错误。 07/29 13:45:04 ERROR [] http.MainServlet.initServletBean:492 - Context initialization failed

【背景】： 1、jenkins部署maven工程做自动编译打包构建 2、工程集成了spring+springboot+mybatis 3、多模块方式部署maven工程，有一个总的pom工程。 4、总的pom工程由上游依赖（已install到仓库中） 【问题描述】： 构建此pom工程给多模块编译打包，报错 ``` ...I18nController.java:package org.springframework.web.bind.annotation does not exist. ...I18nController.java ..cannot find symbol.. ... ``` 【定位】： 1、初步排查应该是缺包导致的问题，根据代码报错找到为导入包为spring-web中的一个类找不到 2、因为继承jenkins构建使用的maven未配置localRepository，因此构建时下载的临时仓库在slave的WORKSPACE下的m2chche目录下。 3、可以明确在该m2chche种找到spring-web对应版本已下载的jar包。 4、在jenkins执行日志中，搜索加载到的"org/springframework/spring"时，其他的spring-jdbc，spring-tx，spring-core，spring-aop等包都能查到，但是查不到spring-web的。 5、根据spring boot的pom文件往上找依赖，在spring-boot-starter 找到spring-boot-starter-web，在往上找到spring-web的依赖，scope配置的 compile 至此暂没有头绪了。 【求助】：请教大家了解maven的朋友，给点指导，谢谢！

【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

课程分为两条主线： 1&nbsp;从Tensorflow的基础知识开始，全面介绍Tensorflow和Keras相关内容。通过大量实战，掌握Tensorflow和Keras经常用到的各种建模方式，参数优化方法，自定义参数和模型的手段，以及对训练结果评估与分析的技巧。 2&nbsp;从机器学习基础算法开始，然后进入到图像分类领域，使用MNIST手写数据集和CIFAR10图像数据集，从简单神经网络到深度神经网络，再到卷积神经网络，最终完成复杂模型：残差网络的搭建。完成这条主线，学员将可以自如地使用机器学习的手段来达到图像分类的目的。
