创建测试word模板： word模板.docx
工具类使用：
public static void main(String[] args) {
Map<String, String> replace = new HashMap<>();
replace.put("name","李四");
replace.put("age", "31");
try {
// word内容替换
CreatePdfUtils.replaceWords("C:\Users\lisi\Desktop\word模板.docx",
"C:\Users\lisi\Desktop\word版文档.docx", replace);
// word转pdf
CreatePdfUtils.wordToPdf("C:\Users\lisi\Desktop\word版文档.docx");
} catch (IOException e) {
throw new RuntimeException(e);
}
}
最终生成的word文档和转换后的pdf:
