ECharts是一款基于JavaScript的數據可視化圖表庫,提供直觀,生動,可交互,可個性化定制的數據可視化圖表。 ECharts最初由百度團隊開源,并于2018年初捐贈給Apache基金會,成為ASF孵化級項目。 2021年1月26日晚,Apache基金會官方宣布ECharts項目正式畢業。

以上只是一些關鍵代碼,所有代碼請參見下面代碼倉庫
Tika是一個內容分析工具,自帶全面的parser工具類,能解析基本所有常見格式的文件,得到文件的metadata,content等內容,返回格式化信息。總的來說可以作為一個通用的解析工具。特別對于搜索引擎的數據抓去和處理步驟有重要意義。Tika是Apache的Lucene項目下面的子項目,在lucene的應用中可以使用tika獲取大批量文檔中的內容來建立索引,非常方便,也很容易使用。Apache Tika toolkit可以自動檢測各種文檔(如word,ppt,xml,csv,ppt等)的類型并抽取文檔的元數據和文本內容。Tika集成了現有的文檔解析庫,并提供統一的接口,使針對不同類型的文檔進行解析變得更簡單。Tika針對搜索引擎索引、內容分析、轉化等非常有用。
應用程序員可以很容易地在他們的應用程序集成Tika。Tika提供了一個命令行界面和圖形用戶界面,使它比較人性化。在本章中,我們將討論構成Tika架構的四個重要模塊。下圖顯示了Tika的四個模塊的體系結構:
每當一個文本文件被傳遞到Tika,它將檢測在其中的語言。它接受沒有語言的注釋文件和通過檢測該語言添加在該文件的元數據信息。支持語言識別,Tika 有一類叫做語言標識符在包org.apache.tika.language及語言識別資料庫里面包含了語言檢測從給定文本的算法。Tika 內部使用N-gram算法語言檢測。
Tika可以根據MIME標準檢測文檔類型。Tika默認MIME類型檢測是使用org.apache.tika.mime.mimeTypes。它使用org.apache.tika.detect.Detector 接口大部分內容類型檢測。內部Tika使用多種技術,如文件匹配替換,內容類型提示,魔術字節,字符編碼,以及其他一些技術。
org.apache.tika.parser 解析器接口是Tika解析文檔的主要接口。該接口從提取文檔中的文本和元數據,并總結了其對外部用戶愿意寫解析器插件。采用不同的具體解析器類,具體為各個文檔類型,Tika 支持大量的文件格式。這些格式的具體類不同的文件格式提供支持,無論是通過直接實現邏輯分析器或使用外部解析器庫。
使用的Tika facade類是從Java調用Tika的最簡單和直接的方式,而且也沿用了外觀的設計模式。可以在 Tika API的org.apache.tika包Tika 找到外觀facade類。通過實現基本用例,Tika作為facade的代理。它抽象了的Tika庫的底層復雜性,例如MIME檢測機制,解析器接口和語言檢測機制,并提供給用戶一個簡單的接口來使用。

啟動Spring Boot應用
前在SpringBoot項目中一直使用的是SpringFox提供的Swagger庫,上了下官網發現已經有接近兩年沒出新版本了!前幾天升級了SpringBoot 2.6.x 版本,發現這個庫的兼容性也越來越不好了,有的常用注解屬性被廢棄了居然都沒提供替代!無意中發現了另一款Swagger庫SpringDoc,試用了一下非常不錯,推薦給大家!
SpringDoc是一款可以結合SpringBoot使用的API文檔生成工具,基于OpenAPI 3,目前在Github上已有1.7K+Star,更新發版還是挺勤快的,是一款更好用的Swagger庫!值得一提的是SpringDoc不僅支持Spring WebMvc項目,還可以支持Spring WebFlux項目,甚至Spring Rest和Spring Native項目,總之非常強大,下面是一張SpringDoc的架構圖。
接下來我們介紹下SpringDoc的使用,使用的是之前集成SpringFox的mall-tiny-swagger項目,我將把它改造成使用SpringDoc。
首先我們得集成SpringDoc,在pom.xml中添加它的依賴即可,開箱即用,無需任何配置。

SpringDoc還有一些常用的配置可以了解下,更多配置可以參考官方文檔。
springdoc:
swagger-ui:
# 修改Swagger UI路徑
path: /swagger-ui.html
# 開啟Swagger UI界面
enabled: true
api-docs:
# 修改api-docs路徑
path: /v3/api-docs
# 開啟api-docs
enabled: true
# 配置需要生成接口文檔的掃描包
packages-to-scan: com.macro.mall.tiny.controller
# 配置需要生成接口文檔的接口路徑
paths-to-match: /brand/**,/admin/**
在SpringFox的Swagger庫好久不出新版的情況下,遷移到SpringDoc確實是一個更好的選擇。今天體驗了一把SpringDoc,確實很好用,和之前熟悉的用法差不多,學習成本極低。而且SpringDoc能支持WebFlux之類的項目,功能也更加強大,使用SpringFox有點卡手的朋友可以遷移到它試試!
