ojdbc中多线程处理resultset结果集的问题

[JavaChuXueZhe06]

在oracle数据库中查数据的时候大概有20W条数据， 我是分页查询的，查询很快，但是对这些处理的时候很耗时，我想通过多线程处理rs，或者每个多线程获取自己的rs，尝试了几次没有成功，还请大神指点一二。。。
代码如下：
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

public class JDBCUtils {
private final static String dbdriver = "oracle.jdbc.driver.OracleDriver";
private final static String dburl = "";
private final static String dbuser = "";
private final static String dbpassword = "";
private static Connection conn = null;
private static PreparedStatement ps = null;
private static ResultSet rs = null;
static {
try {
Class.forName(dbdriver);
} catch (ClassNotFoundException e) {
System.out.println(e);
}
}

public static Connection createConnection() {
try {
conn = DriverManager.getConnection(dburl, dbuser, dbpassword);
} catch (SQLException e) {
System.out.println(e);
}
return conn;
}

public static void main(String[] args) throws SQLException {
conn = createConnection();
int count = 0;
long start = System.currentTimeMillis();
String sql = "select res_name,city from (select rownum ro,res_name ,city from PM_TC_EUTRANCELL_CT_HOUR p) where ro>? and ro <=?";
for (int i = 0; i < 150000; i += 3000) {// 172615
//发现每次查询3000 较好 快且不占那么多内存
ps = conn.prepareStatement(sql);
ps.setObject(1, i);
ps.setObject(2, i + 3000);
rs = ps.executeQuery();
//这里的rs希望通过多线程处理
while (rs.next()) {
count++;
//这里count++模拟数据的处理
}
System.out.println("count--" + count);
}

long stop = System.currentTimeMillis();
System.out.println("处理时间--" + (stop - start));
System.out.println(count);
closeAll();
}

public static void closeAll() {
try {

if (rs != null) {
rs.close();
}

if (ps != null) {
ps.close();
}

if (conn != null) {
conn.close();
System.out.println("连接已关闭");

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

}
