jodconverter4.1.0版本改進解析

jodconverter 4.1.0版本的話,改進了api的結構,同時新增了local以及online的模塊,本文就來分析一下。php

maven

<dependency>
			<groupId>org.jodconverter</groupId>
			<artifactId>jodconverter-spring-boot-starter</artifactId>
			<version>4.1.0</version>
		</dependency>

依賴變化

新版的話,對原來的jodconverter-core進行了抽離,將對libreoffice相關jar包的依賴從core模塊中抽取出來,抽到jodconverter-local模塊當中。 另外也新增了jodconverter-online模塊,以支持libreoffice online server的遠程調用。html

  • Uno local方式是本地啓動libreoffice,而後使用uno進行編程,操做本地的office。 Uno-Arc

相關的jar依賴以下git

<dependency>
    <groupId>org.libreoffice</groupId>
    <artifactId>juh</artifactId>
    <version>5.4.2</version>

</dependency>
  • online

This is LibreOffice Online, which provides basic collaborative editing of documents in a browser by re-using the LibreOffice core. Rendering fidelity should be excellent, and interoperability match that of LibreOffice. 能夠部署到本身的私有云端,而後經過有ui界面能夠操做,也經過http對外提供api服務。 好比github

- API: HTTP POST to /lool/convert-to/<format>
        - the format is e.g. "png", "pdf" or "txt"
        - the file itself in the payload
    - example
        - curl -F "data=@test.txt" https://localhost:9980/lool/convert-to/docx > out.docx
	- or in html:
          <form action="https://localhost:9980/lool/convert-to/docx" enctype="multipart/form-data" method="post">
              File: <input type="file" name="data"><br/>
              <input type="submit" value="Convert to DOCX">
          </form>

jodconverter-online模塊基於這個api使用apache http client進行了client端的封裝並進行鏈接池的優化處理。spring

api變化

4.1.0版本改進了api,方便進行流式操做 舊版的以下docker

jodConverter.convert(inputFile, outputFile);

新版以下apache

File inputFile = new File("spreadsheet.xls");
File outputFile = new File("spreadsheet.ods");
JodConverter
         .convert(inputFile)
         .to(outputFile)
         .execute();

或者編程

InputStream inputStream = ...
OutputStream outputStream = ...
JodConverter
         .convert(inputStream)
         .as(DefaultDocumentFormatRegistry.XLS)
         .to(outputStream)
         .as(DefaultDocumentFormatRegistry.ODS)
         .execute();
