for input string 4294967295

jdbc查询oracle数据库blob字段时出错：

java.lang.NumberFormatException: For input string: “4294967295”

原因：数据库驱动包版本太低

  public int getPrecision(int paramInt)
    throws SQLException
  {
    int i = getValidColumnIndex(paramInt);
    int j = getDescription()[i].describeType;
    switch (j)
    {
    case 112: 
    case 113: 
      return Integer.parseInt(OracleDatabaseMetaData.getLobPrecision());//就是这句，getLobPrecision()返回了一个4294967295，这超出了Integer范围，所以报错，更新jar包即可解决问题
    case 8: 
    case 24: 
      return 2147483647;
    case 1: 
    case 96: 
      return getDescription()[i].describeMaxLength;
    }
    return getDescription()[i].precision;
  }
