java - 如何使用 Java 和 OpenOffice UNO API 操作 odt 文件中的嵌入文件

Question

我找到了一种在 ODF 文件中存储自定义文件的方法，方法是将它们存储在新的资源目录中，并将其包含在新 mimetype 下的 list 中。

我想知道如何在我的 Java OpenOffice 插件中完成以下任务:

1. 读取我的资源中的文件:是否可以获取其内容的 InputStreamReader？
2. 创建新文件:我可以以某种方式创建并写入新文件吗？

关于如何实现这一目标的任何想法。我是 UNO API 的新手，有点困惑。

Answer 1

/* this java code need one jar file named with odfdom-java 0.8.6 , and it will able to read any odt file and can store in string and can also change the content of the original file on new or existing file what ever your requirement . if you want to create new file then give new file name and path at the method "document.save("D:/newFile.odt")".

            } else if (file.getName().endsWith(".odt")) {

                //getting contents of odt file in string

                // for replacing Email id

                        System.out.println("Contact no Removed succesfully :: ");
                    }


                // save the modified document back to a original file other wise it will create new odt file
                document.save(fileName);
            }
        }

        catch (Exception e) {
            //logger.error("Exception : " + e);
            System.out.println("Not found ::");
        }
