Java 添加條碼、二維碼到PDF文檔

本文介紹如何通過Java程式在PDF文檔中添加條碼和二維碼。建立條碼時,可建立多種不同類型的條碼,包括Codebar、Code11、Code128A、Code128B、Code32、Code39、Code39 Extended 、Code93和Code93 Extended等等,本文以其中的Codebar、Code128A和Code39為例介紹建立方法,可通過參考此方法建立其他類型的條碼。

本文中的程式測試環境包括:

  • IDEA
  • JDK 1.8.0
  • Spire.Office.jar

注:jar導入,可通過建立Maven程式項目,并在pom.xml中配置Maven倉庫路徑,并指定Free Spire.Office for Java的Maven依賴,點選“Import Changes”即可導入JAR包。(如果使用的Eclipse, 點選儲存按鈕導入),配置如下:

<repositories>
        <repository>
            <id>com.e-iceblue</id>
            <url>http://repo.e-iceblue.cn/repository/maven-public/</url>
        </repository>
</repositories>

<dependencies>
    <dependency>
      <groupId>e-iceblue</groupId>
      <artifactId>spire.office.free</artifactId>
      <version>3.1.1</version>
    </dependency>
</dependencies>      

另外,也可通過下載下傳jar包,手動導入Spire.Office.jar到Java程式。
