JDBC呼叫資料庫：

package com.hthk.iisz.util;

import java.sql.Connection;
import java.sql.DriverManager;

public class SqlServerConnectionzUtil {
 public static Connection getConnection() {
  String driverName = "oracle.jdbc.driver.OracleDriver";
  String dbURL = "jdbc:oracle:thin:@172.25.15.139:1526:atomsu";
  String userName = "atoms";
  String userPwd = "abc123";
  Connection dbConn = null;
  try {
   Class.forName(driverName);
   dbConn = DriverManager.getConnection(dbURL, userName, userPwd);
   System.out.println("連線資料庫成功");
   return dbConn;
  } catch (Exception e) {
   e.printStackTrace();
   System.out.print("連線失敗");
  }
  return dbConn;
 }
}
 

連線好資料庫後呼叫其儲存過程和執行SQL語句：

package com.hthk.iisz.dao;

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.sql.Types;

import com.hthk.iisz.util.SqlServerConnectionzUtil;

public class TcnConnectDatabaseDao {

 Connection conn;
 PreparedStatement stmt;
 ResultSet rs;

 public int getConnection(String id, String phone) throws SQLException {
  try {
   Connection conn = SqlServerConnectionzUtil.getConnection();// 得到jdbc
                  // Connection
   CallableStatement cstmt = conn
     .prepareCall("{call  mytv_super_pkg.CHECK_STATUS(?,?,?)}");// 呼叫儲存過程
   cstmt.setString(1, id);// in引數
   cstmt.setString(2, phone);// in引數
   System.out.println(id+"--------"+phone);
   cstmt.registerOutParameter(3, Types.INTEGER);// out引數
   cstmt.execute();
   return cstmt.getInt(3);// 得到3位置的out值
  } catch (SQLException e) {
   e.printStackTrace();
   return 0;
  }
 }

 public String getExpiryDate(String id) throws SQLException {
  try {
   Connection conn = SqlServerConnectionzUtil.getConnection();// 得到jdbc
                  // Connection
   Statement stmt = conn.createStatement();
   ResultSet rs = stmt
     .executeQuery("select expiry_date from mytv_super_offer where random_id="
       + id);// 執行SQL語句
   while (rs.next()) {
    return rs.getString("expiry_date");
   }
  } catch (SQLException e) {
   e.printStackTrace();
   return null;
  } finally {
   // 關閉資料庫,一般是後開的先關,對應上面
   try {
    if (rs != null) {
     // 如果rs一開始就是null的話，如果不判斷就一直出SQL異常，所以應該先判斷一下
     rs.close();
    }
    if (stmt != null) {
     // 如果stmt一開始就是null的話，如果不判斷就一直出SQL異常，所以應該先判斷一下
     stmt.close();
    }
    if (conn != null) {
     // 如果conn一開始就是null的話，如果不判斷就一直出SQL異常，所以應該先判斷一下
     conn.close();
    }
   } catch (SQLException se) {
    se.printStackTrace();
   }
  }
  return null;
 }
}
