What's the best library for reading Outlook .msg files in Java?
提问by muriloq
I would like to read the text and binary attachments in a saved Outlook message (.msg file) from a Java application, without resorting to native code (JNI, Java Native Interface).
我想从 Java 应用程序读取保存的 Outlook 消息（.msg 文件）中的文本和二进制附件，而不使用本机代码（JNI，Java 本机接口）。
Apache POI-HSMFseems to be in the right direction, but it's in very early stages of development...

You could use Apache POIFS, which seems to be a little more mature, but that would appear to duplicate the efforts of POI-HSMF.
You could use POI-HSMF and contribute changes to get the features you need working. That's often how FOSS projects like that expand.
You could use com4j, j-Interop, or some other COM-level interop feature and interact directly with the COM interfaces that provide access to the structured document. That would be much easier than trying to hit it directly through JNI.
您可以使用 Apache POIFS，它似乎更成熟一些，但这似乎重复了 POI-HSMF 的工作。
您可以使用 POI-HSMF 并进行更改以获得所需的功能。像这样的 FOSS 项目通常就是这样扩展的。
您可以使用 com4j、j-Interop 或其他一些 COM 级别的互操作功能，并直接与提供对结构化文档的访问的 COM 接口交互。这比尝试通过 JNI 直接命中要容易得多。

msgparseris a small open source Java library that parses Outlook .msg files and provides their content using Java objects. msgparser uses the Apache POI - POIFSlibrary to parse the message files which use the OLE 2 Compound Document format.
msgparser是一个小型开源 Java 库，用于解析 Outlook .msg 文件并使用 Java 对象提供其内容。msgparser 使用Apache POI - POIFS库来解析使用 OLE 2 复合文档格式的消息文件。

Have you tried to use Jython with the Python win32 extensions (http://www.jython.org/Project/+ http://python.net/crew/mhammond/win32/)? If this is for a "personal" or "internal" project Jython with Python may be a very good choice. If you are building a "shrink wrapped" software package this may not be the best option.
您是否尝试过将 Jython 与 Python win32 扩展（http://www.jython.org/Project/+ http://python.net/crew/mhammond/win32/）一起使用？如果这是用于“个人”或“内部”项目，Jython with Python 可能是一个非常好的选择。如果您正在构建“收缩包装”软件包，这可能不是最佳选择。
