}二、pdf转html
依赖:
<dependency>
<groupid>net.sf.cssbox</groupid>
<artifactid>pdf2dom</artifactid>
</dependency>
<dependency>
<groupid>net.mabboud.fontverter</groupid>

</dependency>
<dependency>
<groupid>org.reflections</groupid>
<artifactid>reflections</artifactid>
</dependency>
<!--pdf转文本-->
<dependency>

</dependency>代码:
import org.apache.pdfbox.pdmodel.pddocument;

// 获取html内容

}
pdfcontent = string.valueof(htmlcontent);
return pdfcontent;
} catch (ioexception e) {
e.printstacktrace();
system.err.println("读取 html 文件时出错。");
}
return null;
}
}三、方法补充
java实现word转html
1.引入maven依赖
<properties>
<poi.version>5.2.3</poi.version>
<xhtml.version>2.0.4</xhtml.version>
</properties>
<!--word转html-->
<dependency>
<groupid>org.apache.poi</groupid>

</dependency>

2.java代码

}
return null;
}

return writer.tostring();
} catch (exception e) {

}
return null;
}
/**

<artifactid>pdf2dom</artifactid>
<version>2.0.3</version>
</dependency>
<dependency>

<!--pdf转文本-->
<dependency>
<groupid>org.apache.pdfbox</groupid>
<artifactid>pdfbox</artifactid>
<version>2.0.24</version>
</dependency>实现关键代码
file file = new file(pdfurl);
string localpdffilepath = 要解析的pdf文件路径(本地)+ file.getname();
string newpdffilepath = 截取pdf后生成的pdf文件路径+ file.getname();
string outfilepath = 生成的html文件.html";
string pdfcontent = "";
pddocument pdfdocument = pddocument.load(new file(localpdffilepath));
// 检查文档中是否有页面
if (pdfdocument.getnumberofpages() > 0) {
// 移除第一页
pdfdocument.removepage(0);
}
// 保存更改后的pdf到新文件
pdfdocument.save(new file(newpdffilepath));
system.out.println("第一页已被移除,新pdf保存在: " + newpdffilepath);
pdfdocument.close();
// 转换成html格式文件
pddocument document = pddocument.load(new file(newpdffilepath));
writer writer = new printwriter(outfilepath, "utf-8");
new pdfdomtree().writetext(document, writer);
writer.close();
document.close();
// 获取html内容
try (bufferedreader reader = new bufferedreader(new filereader(outfilepath))) {
stringbuilder htmlcontent = new stringbuilder();
string line;
while ((line = reader.readline()) != null) {
htmlcontent.append(line).append("\n"); // 追加每一行内容,并添加换行符
}
pdfcontent = string.valueof(htmlcontent);
} catch (ioexception e) {
e.printstacktrace();
system.err.println("读取 html 文件时出错。");
