The template file is as follows:
1. Introduce third-party dependencies
3. Generate a new PPT according to the template
Project requirements
In recent projects, there is a need to let Java code replace manual operation and automatically generate PPT, specifically, query database data, and then combine database data and template file (PPT) according to template file (PPT). Generate a new PPT file.
The template file is as follows:
Put the name, progress rate, continuous progress times , and pictures in the template file . Replace with specific person information .
Implementation process:
1. Introduce third-party dependencies
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>3.15</version>
</dependency>Apache POI is a free and open source cross-platform Java API written in Java. Apache POI provides APIs for Java programs to read and write Microsoft Office format files. POI is an acronym for "Poor Obfuscation Implementation", which means "Concise Obfuscation Implementation".
HSSF－提供读写MicrosoftExcelXLS格式档案的功能
XSSF－提供读写MicrosoftExcelOOXMLXLSX格式档案的功能
HWPF－提供读写MicrosoftWordDOC格式档案的功能
HSLF－提供读写MicrosoftPowerPoint格式档案的功能
HDGF－提供读MicrosoftVisio格式档案的功能
HPBF－提供读MicrosoftPublisher格式档案的功能
HSMF－提供读MicrosoftOutlook格式档案的功能
2. Write business code
