java – 将希伯来字符插入MySQL表时获取问号

DDL如下：

String cityTable = "CREATE TABLE IF NOT EXISTS hebrew_test.table ("
                            +"id int(11) NOT NULL AUTO_INCREMENT,"
                            +"en varchar(30) NOT NULL,"
                            +"he varchar(30) COLLATE utf8_bin NOT NULL,"
                            +"PRIMARY KEY (id)"
                            +") ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin AUTO_INCREMENT=1;";
String insert = "INSERT INTO hebrew_test.table (en,he) VALUES ('A','a')";
String insert2 = "INSERT INTO hebrew_test.table (en,he) VALUES ('B','?')";
String insert3 = "INSERT INTO hebrew_test.table (en,he) VALUES ('C','???')";


executeSQLCommand(cityTable);
executeSQLCommand(insert);
executeSQLCommand(insert2);
executeSQLCommand(insert3);

我得到的输出表：

1   A   a
2   B   ?
3   C   ???

代替：

1   A   a
2   B   ?
3   C   ???

我试过Hebrew appears as question marks in Netbeans,但那不是同一个问题.我在表格中得到了问号.

我还将表定义为UTF8_bin,如上面的代码所示.
