例外 - 值java.sql.SQLException：不允許操作的ResultSet關閉

Question

我越來越喜歡爲

java.sql.SQLException: Before start of result set when calling getInt() method 

我的代碼如下:::

public void setdateTOSource(){ 
    try{ 
     String q = "SELECT * FROM ipp.resource;"; 
     ResultSet result = DB_Access.getData(q); 
     System.out.println("Size result set"+result.getFetchSize()); 
     while(result.next()){ 
      getIpSource().add(result.getString(1)); 
      System.out.println(result.getString(1)); 

     } 
     System.out.println("source size "+getIpSource().size());  
    } 
    catch(Exception e){ 
     System.out.println(e); 
    } 
} 
public void insertTargetToDb(List<String> targetValue){ 

    try{ 
     Connection con = DB_Connect.getDataBaseConnection(); 
     Statement statement1 = con.createStatement(); 

     int val=0; 
     String q1 = "SELECT MAX(area_id) as aa FROM ipp.area;"; 
     ResultSet resultset = statement1.executeQuery(q1); 
     if(resultset.next()){ 
      val = resultset.getInt(1); 
     };   
     val++; 

     String q2 = "INSERT INTO ipp.area VALUES("+val+",'"+getAreaName()+"',1);"; 
     Statement statement2 = con.createStatement(); 
     statement1.executeUpdate(q2); 
     for(int y=0;y<targetValue.size();y++){ 

      System.out.println("FS"); 

      String ip=targetValue.get(y); 
      System.out.println("ip" +ip); 
      String q3 ="SELECT resource_id FROM ipp.resource r where ip_address like '"+ip+"%';"; 
      Statement statement3 = con.createStatement(); 
      ResultSet resultset3 =statement3.executeQuery(q3); 

      System.out.println("FS1"); 
//   ResultSet result1 =DB_Access.getData(q3); 
      System.out.println("FS2"); 
      System.out.println("result set"+resultset3.getFetchSize()); 
//====================================================================    
while(resultset3.next()){ 
       setId(resultset.getInt(1)); 
      }   
      System.out.println("result :........."+resultset3.getInt("resource_id")); 
      System.out.println("FS3"); 

      String q4 = "INSERT INTO ipp.used_resource VALUES("+val+","+getId()+");"; 
      Statement statement4= con.createStatement(); 
      statement4.executeUpdate(q4); 
//   DB_Access.setData(q3); 
      statement3.close(); 
      statement4.close(); 
//   resultset3.close(); 
     } 
     resultset.close(); 
     statement1.close(); 
     statement2.close(); 
     con.close(); 
     addMessage("Area created Successfully"); 


    } 
    catch(Exception e){ 
     System.out.println(e); 
    } 
} 

異常自帶行後發生異常後，

// ========================== RESOURCE_ID是一個整數值

此行

while(resultset3.next()){ 
       setId(resultset.getInt(1)); 
      } 

必須被替換？

while(resultset3.next()){ 
       setId(resultset3.getInt(1)); 
      }
