MySql 插入数据 帮忙看一下方法有什么问题

Java code:


public static void insertSong(List<Tone32> toneList){
Test23 t = new Test23();
try{
conn=t.getConn();
for(Tone32 tone : toneList){
String sql = "insert into tone (toneType,song,artist,price) values(?,?,?,?)";

pstm = conn.prepareStatement(sql);
pstm.setString(1, tone.getToneType());
pstm.setString(2, tone.getSong());
pstm.setString(3, tone.getArtist());
pstm.setDouble(4, tone.getPrice());

pstm.executeUpdate();
}
t.Close();
System.out.println("入库结束");
}catch(Exception e){
e.printStackTrace();
}
}




向MYSQL 里插入数据  我的toneList里有28000左右的数据

但是插入 12000多条的时候 抛异常

Java code:
