You can find a mail with Content-Type: TEXT/HTMLlike this:
你可以找到这样的邮件Content-Type: TEXT/HTML：
Object content = message.getContent();
if (content instanceof Multipart) {
Multipart mp = (Multipart) content;
for (int i = 0; i < mp.getCount(); i++) {
BodyPart bp = mp.getBodyPart(i);
if (Pattern
.compile(Pattern.quote("text/html"),
Pattern.CASE_INSENSITIVE)
.matcher(bp.getContentType()).find()) {
// found html part
System.out.println((String) bp.getContent());
} else {
// some other bodypart...
}
}
}
Output:
输出：
<H1>Hi there</H1><p>Bye.</p>
