创建测试word模板： word模板.docx

工具类使用：

typescript 复制代码

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);
    }
}
