JDBC 使用批量插入的方式操作longtext、longblob类型的字段，插入的数据超过32K，字段值就会变成dat文件名，而单条操作字段值则正常，驱动包：gbase-connector-java-9.5.0.1-build1-bin.jar

使用批量提交，插入之后LONGTEXT、LONGBLOB字段值会变成T--1-1782994247-167481407-140437503252224.dat、T--1-1782994247-168814956-140437503252224.dat
    public static void insert() {

        String url = "jdbc:gbase://IP:5258/sysdb?autoReconnect=true&zeroDateTimeBehavior=round&transformedBitIsBoolean=true";
        try {
            Connection con = DriverManager.getConnection(url, "root", "123456");
            PreparedStatement psmt = null;

            String sql = "INSERT INTO test1 (id, name1, name2) VALUES (1, ?, ?)";
            psmt = con.prepareStatement(sql);
            con.setAutoCommit(false);


            StringBuilder stringBuilder64 = new StringBuilder();
            for (int i = 0; i < 65536; i++) {
                stringBuilder64.append("A");
            }

            for (int i = 1; i <= 1; i++) {

                if(i==1){
                    psmt.setString(1, stringBuilder64.toString());
                    psmt.setBytes(2, stringBuilder64.toString().getBytes());
                }
                psmt.addBatch();
            }
            psmt.executeBatch();
            con.commit();
            psmt.clearBatch();
            con.setAutoCommit(true);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

如果不使用批量插入，LONGTEXT、LONGBLOB字段值就是正常的：AAAAAA……

StringBuilder stringBuilder = new StringBuilder();
for (int i = 0; i < 65536; i++) {
    stringBuilder.append("A");
}
String sourceUrl = "jdbc:gbase://IP:5258/sysdb?autoReconnect=true&zeroDateTimeBehavior=round&transformedBitIsBoolean=true";

String sourceUser = "root";
String sourcePassword = "123456";

Connection sourceConn = null;
Connection targetConn = null;
PreparedStatement sourceStmt = null;
PreparedStatement targetStmt = null;
ResultSet rs = null;


try {
    // 连接源数据库
    sourceConn = DriverManager.getConnection(sourceUrl, sourceUser, sourcePassword);
    sourceStmt = sourceConn.prepareStatement("INSERT INTO test1 (id, name1, name2) VALUES (2, ?, ?)");
    sourceStmt.setString(1, stringBuilder.toString());

    sourceStmt.setBytes(2, stringBuilder.toString().getBytes());
    sourceStmt.execute();


    System.out.println("Data transferred successfully.");
} catch (SQLException e) {
    e.printStackTrace();
} finally {

}

为什么会出现这种情况？
