Java執行Oracle儲存過程並接收多個返回值(集合/數值)

Java程式碼：

package com.pure.util;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;

public class DBHelper {

	public Connection getConnection(){
		Connection conn=null;
		try{
			//Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");//SqlServer
			//conn=DriverManager.getConnection("jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=test", "sa", "123");
			
			Class.forName("oracle.jdbc.driver.OracleDriver");
			conn=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:test","root","123");

		}catch(Exception e){
			e.printStackTrace();
		}
		return conn;
	}
	public void close(ResultSet rs,PreparedStatement ps,Connection conn){
		try{
			if(rs!=null){
				rs.close();
			}
			if(ps!=null){
				ps.close();
			}
			if(conn!=null){
				conn.close();
			}
		}catch(Exception e){
			e.printStackTrace();
		}
	}
	public static void main(String[] args) {
		DBHelper db=new DBHelper();
		System.out.println(db.getConnection());
	}
}
 

package test;

import java.sql.ResultSet;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import oracle.jdbc.OracleTypes;
import com.util.DBHelper;

public class Test {
	/**

	 * java -jar test.jar 14 
	 * @param args
	 */
	public static void main(String[] args) {
		//System.out.println("數量="+testCall(parseInt(args[0]))); //jar執行
		System.out.println("數量="+testCall(14));
	}
	public static int testCall(int param){
		DBHelper db=new DBHelper();
		Connection conn= db.getConnection();
		
		int count = 0;
		try{
			CallableStatement call=conn.prepareCall("{call sp_test_1(?,?,?)}");//執行sp_test_1儲存過程(注：儲存過程接收引數和輸出引數Java都有打？問號)
			call.setInt(1, param);//設定引數
			call.registerOutParameter(2, OracleTypes.INTEGER);//接收返回值
			call.registerOutParameter(3,OracleTypes.CURSOR);//接收返回值
			call.execute();//執行
		
			count=call.getInt(2); //拿取儲存過程返回值 
			
			
			List<Map> list=new ArrayList<Map>(); 
			//ResultSet rs=call.getResultSet();
			ResultSet rs=(ResultSet)call.getObject(3);//拿取儲存過程返回的集合
			while(rs.next()){
				Map map=new HashMap();
				map.put("id", rs.getInt("ID"));
				map.put("user_name", rs.getString("USER_NAME"));
				map.put("login_name", rs.getInt("LOGIN_NAME"));
				list.add(map);
			}
			
			System.out.println("listSize="+list.size());
			
		
		}catch(Exception e){
			e.printStackTrace();
		}finally{
			
		}
		return count;
	}
	public static int parseInt(Object obj){
		try{
			return Integer.parseInt(obj.toString());
		}catch(Exception e){
			return 0;
		}
	} 
}
