Java邮件邮件正文
我正在尝试读取电子邮件,将电子邮件保存为对象,保存其附件,然后将对象作为JSON发布到API。除了主体仅作为com.sun.mail.util输出外,其他一切都正常工作。BASE64DecoderStream@1q9q9qj4. 我以为代码会处理带有附件的消息体,但它似乎不起作用Java邮件邮件正文,java,jakarta-mail,pop3,Java,Jakarta Mail,Pop3,我正在尝试读取电子邮件,将电子邮件保存为对象,保存其附件,然后将对象作为JSON发布到API。除了主体仅作为com.sun.mail.util输出外,其他一切都正常工作。BASE64DecoderStream@1q9q9qj4. 我以为代码会处理带有附件的消息体,但它似乎不起作用 public class ReadEmails { private static String saveDirectory = "C://attachments"; public void setS

您的问题不清楚<代码>正文仅输出为com.sun.mail.util。BASE64DecoderStream@1q9q9qj4输出在哪里?如果不清楚,很抱歉,当我将NewCase对象发布到API时,它会被输入到数据库中。在这里,保存消息的字段包含com.sun.mail.util。BASE64DecoderStream@1q9q9qj4而不是实际的消息。API和数据库在其他方面工作得很好,所以我认为在将NewCase对象转换为JSO对象时可能会出现问题。问题在于将part.getContent()
转换为字符串时,因为这里的part.getContent()
是一个实例
