java - 如何使用 Apache POI HSMF 读取公共(public)属性

Question

我尝试使用 POI hsmf 从 Outlook .msg 文件中提取字段 BillingInformation，但每次都会收到 ChunkNotFoundException。我已在 Outlook 中验证该字段中有内容。

public class MessageReader {
    private static final int SUBJECT_CHUNK = 0x0037;
    private static final int BILLING_INFORMATION_CHUNK = 0x00008535;
    public static void main(String[] argv) {
        try {
            MAPIMessage mapiMessage = new MAPIMessage("MessageWithBillingInformation.msg");
            System.out.println(mapiMessage.getStringFromChunk(new StringChunk(SUBJECT_CHUNK, true)));
            System.out.println(mapiMessage.getStringFromChunk(new StringChunk(BILLING_INFORMATION_CHUNK, true)));
        } catch (IOException e) {
            e.printStackTrace();  
        } catch (ChunkNotFoundException e) {
            e.printStackTrace();  
        }
    }
}

我找到的所有文档都将 0x00008535 列为帐单信息的正确 ID: http://msdn.microsoft.com/en-us/library/cc765867.aspx

谢谢

Answer 1

使用 chunkID 0x800A 可以读取账单信息字段，因此代码如下所示:

public class MessageReader {
private static final int SUBJECT_CHUNK = 0x0037;
private static final int BILLING_INFORMATION_CHUNK = 0x800A;
public static void main(String[] argv) {
    try {
        MAPIMessage mapiMessage = new MAPIMessage("MessageWithBillingInformation.msg");
        System.out.println(mapiMessage.getStringFromChunk(new StringChunk(SUBJECT_CHUNK, true)));
        System.out.println(mapiMessage.getStringFromChunk(new StringChunk(BILLING_INFORMATION_CHUNK, true)));
    } catch (IOException e) {
        e.printStackTrace();  
    } catch (ChunkNotFoundException e) {
        e.printStackTrace();  
    }
}

}
