我试图从文本文件中获取数据并插入到 mysql 数据库中。一些行已成功插入,但是在运行程序时它显示此错误消息。
java.io.IOException: Read error

这是我的程序
public class InsertDB {
Connection conn ;
String url = "jdbc:mysql://localhost:3306/";
String dbName = "dna";
String driver = "com.mysql.jdbc.Driver";
String userName = "root";
String password = "123";
public void inserdata()
{
String[] RowItems = new String[11];
int[] intRowItems=new int[10];
try{
conn = DriverManager.getConnection(url+dbName,userName,password);
Statement st = conn.createStatement();
// Open the file that is the first
// command line parameter
FileInputStream fstream = new FileInputStream("result.txt");
// Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
StringTokenizer stringTokenizer ;
while ((strLine = br.readLine()) != null) {
stringTokenizer=new StringTokenizer(strLine);
int j=0;
while(stringTokenizer.hasMoreTokens()){
RowItems[j]=stringTokenizer.nextToken();
j++;
}
int c2,c3,c4,c5,c6,c7,c8,c9,c10,c11;
c2=Integer.valueOf(RowItems[1]).intValue();
c3=Integer.valueOf(RowItems[2]).intValue();
c4=Integer.valueOf(RowItems[3]).intValue();
c5=Integer.valueOf(RowItems[4]).intValue();
c6=Integer.valueOf(RowItems[5]).intValue();
c7=Integer.valueOf(RowItems[6]).intValue();
c8=Integer.valueOf(RowItems[7]).intValue();
c9=Integer.valueOf(RowItems[8]).intValue();
c10=Integer.valueOf(RowItems[9]).intValue();
c11=Integer.valueOf(RowItems[10]).intValue();
String temp=RowItems[0];
String insert="INSERT into protein_predicted VALUES('"+temp+"','"+c2+"','"+c3+"','"+c4+"','"+c5+"','"+c6+"','"+c7+"','"+c8+"','"+c9+"',' "+c10+"','"+c11+"')";
st.executeUpdate(insert);
in.close();
}
System.out.println("Insertted successfully");
}
catch (SQLException e) {
throw new RuntimeException(e);
}
catch (Exception e){//Catch exception if any
//System.err.println("Error: " + e.getMessage());
e.printStackTrace();
//Close the input stream
}
}
public static void main(String args[])
{
InsertDB a=new InsertDB();
a.inserdata();
}
我的文本文件包含这样的多列和多行
1BG8A 76 33 0 18 1 0 1 5 2 16
请帮我解决这个问题..谢谢
