public class InsertWords {
/**

*/
public static void main(String[] args) throws Exception{
// TODO 自动生成方法存根
DBtools.connect();
Connection conn = DBtools.conn;
PreparedStatement pstmt = conn.prepareStatement("insert into words values(?,?)");
ClassLoader cl = InsertWords.class.getClassLoader();
BufferedReader br = new BufferedReader(new InputStreamReader(cl.getResourceAsStream("cet4.txt")));
String s,word,mean;
s = br.readLine();
while(s!=null){
int i = s.indexOf(" ");
if(i==-1) {
s = br.readLine();
continue;
}
word = s.substring(0,i );
mean = s.substring(i);
System.out.print(word);
System.out.println(mean);
pstmt.setString(1, word);
pstmt.setString(2,mean);
pstmt.executeUpdate();
s = br.readLine();

追问：；没有 我都能录入 但是库里显示的本该是中文的地方 却是问号
答案：加qq8293813
其他：该不会是命令里word指词汇，你输入word，和命令冲突吧。 数据库里主键冲突了，相同记录已经存在，例如abandon
上一个：mysql数据库创建带union 的 视图时报错
下一个：有关于XAMPP 的问题-MySQL 数据库 未激活
