ECharts是一款基于JavaScript的数据可视化图表库,提供直观,生动,可交互,可个性化定制的数据可视化图表。 ECharts最初由百度团队开源,并于2018年初捐赠给Apache基金会,成为ASF孵化级项目。 2021年1月26日晚,Apache基金会官方宣布ECharts项目正式毕业。

以上只是一些关键代码,所有代码请参见下面代码仓库
Tika是一个内容分析工具,自带全面的parser工具类,能解析基本所有常见格式的文件,得到文件的metadata,content等内容,返回格式化信息。总的来说可以作为一个通用的解析工具。特别对于搜索引擎的数据抓去和处理步骤有重要意义。Tika是Apache的Lucene项目下面的子项目,在lucene的应用中可以使用tika获取大批量文档中的内容来建立索引,非常方便,也很容易使用。Apache Tika toolkit可以自动检测各种文档(如word,ppt,xml,csv,ppt等)的类型并抽取文档的元数据和文本内容。Tika集成了现有的文档解析库,并提供统一的接口,使针对不同类型的文档进行解析变得更简单。Tika针对搜索引擎索引、内容分析、转化等非常有用。
应用程序员可以很容易地在他们的应用程序集成Tika。Tika提供了一个命令行界面和图形用户界面,使它比较人性化。在本章中,我们将讨论构成Tika架构的四个重要模块。下图显示了Tika的四个模块的体系结构:
每当一个文本文件被传递到Tika,它将检测在其中的语言。它接受没有语言的注释文件和通过检测该语言添加在该文件的元数据信息。支持语言识别,Tika 有一类叫做语言标识符在包org.apache.tika.language及语言识别资料库里面包含了语言检测从给定文本的算法。Tika 内部使用N-gram算法语言检测。
Tika可以根据MIME标准检测文档类型。Tika默认MIME类型检测是使用org.apache.tika.mime.mimeTypes。它使用org.apache.tika.detect.Detector 接口大部分内容类型检测。内部Tika使用多种技术,如文件匹配替换,内容类型提示,魔术字节,字符编码,以及其他一些技术。
org.apache.tika.parser 解析器接口是Tika解析文档的主要接口。该接口从提取文档中的文本和元数据,并总结了其对外部用户愿意写解析器插件。采用不同的具体解析器类,具体为各个文档类型,Tika 支持大量的文件格式。这些格式的具体类不同的文件格式提供支持,无论是通过直接实现逻辑分析器或使用外部解析器库。
使用的Tika facade类是从Java调用Tika的最简单和直接的方式,而且也沿用了外观的设计模式。可以在 Tika API的org.apache.tika包Tika 找到外观facade类。通过实现基本用例,Tika作为facade的代理。它抽象了的Tika库的底层复杂性,例如MIME检测机制,解析器接口和语言检测机制,并提供给用户一个简单的接口来使用。

启动Spring Boot应用
前在SpringBoot项目中一直使用的是SpringFox提供的Swagger库,上了下官网发现已经有接近两年没出新版本了!前几天升级了SpringBoot 2.6.x 版本,发现这个库的兼容性也越来越不好了,有的常用注解属性被废弃了居然都没提供替代!无意中发现了另一款Swagger库SpringDoc,试用了一下非常不错,推荐给大家!
SpringDoc是一款可以结合SpringBoot使用的API文档生成工具,基于OpenAPI 3,目前在Github上已有1.7K+Star,更新发版还是挺勤快的,是一款更好用的Swagger库!值得一提的是SpringDoc不仅支持Spring WebMvc项目,还可以支持Spring WebFlux项目,甚至Spring Rest和Spring Native项目,总之非常强大,下面是一张SpringDoc的架构图。
接下来我们介绍下SpringDoc的使用,使用的是之前集成SpringFox的mall-tiny-swagger项目,我将把它改造成使用SpringDoc。
首先我们得集成SpringDoc,在pom.xml中添加它的依赖即可,开箱即用,无需任何配置。

SpringDoc还有一些常用的配置可以了解下,更多配置可以参考官方文档。
springdoc:
swagger-ui:
# 修改Swagger UI路径
path: /swagger-ui.html
# 开启Swagger UI界面
enabled: true
api-docs:
# 修改api-docs路径
path: /v3/api-docs
# 开启api-docs
enabled: true
# 配置需要生成接口文档的扫描包
packages-to-scan: com.macro.mall.tiny.controller
# 配置需要生成接口文档的接口路径
paths-to-match: /brand/**,/admin/**
在SpringFox的Swagger库好久不出新版的情况下,迁移到SpringDoc确实是一个更好的选择。今天体验了一把SpringDoc,确实很好用,和之前熟悉的用法差不多,学习成本极低。而且SpringDoc能支持WebFlux之类的项目,功能也更加强大,使用SpringFox有点卡手的朋友可以迁移到它试试!
