摘要: JAVAMAIL中提供搜索郵件的API，具體用法可以參考之前的博文，下面是我對其源代碼的學習：
1、運行實例：
package mysearch;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
public class ...

摘要: 關于BASE64編碼，建議參看WIKI中的相關說明。
1、編碼：

摘要: 對于email地址的定義，可以參考RFC822，里面有詳細的說明。
1、采用正則表達式的方式來驗證email地址：
JS處理方式（來自javascript.internet.com的Sandeep V. Tamhankar）：
function checkEmail(emailStr) {
if (emailStr.leng...

1、主要代碼：
/** *//**
* 搜索郵件
*/
public static void search(String subject, String from, boolean or) throws Exception 
{
Session session = Session.getDefaultInstance(System.getProperties(), null);
// session.setDebug(true);
Store store = session.getStore(new URLName("imap://test:test@127.0.0.1"));
store.connect();
Folder folder = store.getDefaultFolder();
// 在收件箱中搜索
folder = folder.getFolder("INBOX");
folder.open(Folder.READ_ONLY);
List<SearchTerm> terms = new ArrayList<SearchTerm>();
// 按主題查詢
terms.add(new SubjectTerm(subject));
// 按發件人查詢
terms.add(new FromStringTerm(from));
// 一個小時內的郵件(我本地的Megic Winmail郵件服務器查不到內容）
// long time = System.currentTimeMillis();
// SentDateTerm dateTerm = new SentDateTerm(ComparisonTerm.GE, new Date(
// time - 60 * 60 * 1000));
// terms.add(dateTerm);
SearchTerm arrays[] = new SearchTerm[terms.size()];
terms.toArray(arrays);
SearchTerm term = or ? new OrTerm(arrays) : new AndTerm(arrays);
Message[] msgs = folder.search(term);
System.out.println("FOUND " + msgs.length + " MESSAGES");
for (int i = 0; i < msgs.length; i++) {
System.out.println("--------------------------");
System.out.println("MESSAGE #" + (i + 1) + ":");
dumpEnvelope(msgs[i]);
}
}
/** *//**
* 打印郵件的內容
*
* @param m
* @throws Exception
*/
public static void dumpEnvelope(Message m) throws Exception {
Address[] a;
if ((a = m.getFrom()) != null) {
for (int j = 0; j < a.length; j++)
System.out.println("FROM: " + a[j].toString());
}
if ((a = m.getRecipients(Message.RecipientType.TO)) != null) {
for (int j = 0; j < a.length; j++) {
System.out.println("TO: " + a[j].toString());
}
}
System.out.println("SUBJECT: " + m.getSubject());
Date d = m.getSentDate();
System.out.println("SendDate: " + (d != null ? d.toString() : "UNKNOWN"));
}
public static void main(String[] args) {
try {
search("subject", "test2@test.com", false);
System.out.println("\n");
search("Fw: test", "test2@test.com", false);
System.out.println("\n");
search("null", "test2@test.com", true);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
2、測試輸出：
FOUND 0 MESSAGES
FOUND 1 MESSAGES
--------------------------
MESSAGE #1:
FROM: test2 <test2@test.com>
TO: test <test@test.com>
SUBJECT: Fw: test
SendDate: Tue Apr 21 20:38:23 CST 2009
FOUND 2 MESSAGES
--------------------------
MESSAGE #1:
FROM: test2 <test2@test.com>
TO: test <test@test.com>
SUBJECT: 測試郵件
SendDate: Mon Apr 20 21:42:53 CST 2009
--------------------------
MESSAGE #2:
FROM: test2 <test2@test.com>
TO: test <test@test.com>
SUBJECT: Fw: test
SendDate: Tue Apr 21 20:38:23 CST 2009
3、相關說明：
如果采用debug模式的話，可以看到調用和搜索串之間的對應關系：
第一次：SEARCH SUBJECT subject FROM test2@test.com ALL
第二次：SEARCH SUBJECT "Fw: test" FROM test2@test.com ALL
第三次：SEARCH OR SUBJECT null FROM test2@test.com ALL
