Java replaces the word document text and inserts an image at a specified position, and word inserts an image.

Java replaces the word document text and inserts an image at a specified position, and word inserts an image.

First, describe the dependent package.

<Dependency> <groupId> org. apache. poi </groupId> <artifactId> poi-excelant </artifactId> <version> 3.12 </version> </dependency> <groupId> org. apache. poi </groupId> <artifactId> poi-scratchpad </artifactId> <version> 3.12 </version> </dependency> <groupId> org. apache. poi </groupId> <artifactId> poi-ooxml </artifactId> <version> 3.8 </version> </dependency> <groupId> org. apache. p Oi </groupId> <artifactId> poi-ooxml-schemas </artifactId> <version> 3.8 </version> </dependency> <! -- Generate an image --> <dependency> <groupId> org. jfree </groupId> <artifactId> jfreechart </artifactId> <version> 1.0.19 </version> </dependency> <! -- Images can be inserted --> <groupId> org.docx 4j </groupId> <artifactId> docx4j </artifactId> <version> 3.3.1 </version> </dependency>

Example,

For example, if "$1" is "1231" in the string to be replaced, insert a bookmark at the specified position and name it "test". The inserted image is as follows:

I am not doing too much research. It is valid for my tests.
