Excel向数据库插入数据（执行一次只需连接一次）-batch简单使用

     由于前端时间向数据库插入excel中的数据时，每插入一条数据，就得连接一次数据库；后来发现这种做法不好，如果excel中有很多条数据，就得连接很多次数据库，这样就很浪费资源而且不安全，有时数据库也会报连接次数过多的异常，所以这次换了中处理方法，batch的简单用法。

1.上图就是本次所要上传数据库的数据的excel表，所需jar包：jxl.jar，ojdbc6.jar，使用mysql就mysql-connector-java-5.1.22-bin.jar；

2.创建实体类；

package com.excel.model;

import java.util.Date;

public class PHSample {
private String  id;                  
private String  sample_num;          
private String  customer_name;

private String  general;

3，创建dao

package com.excel.dao;

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

public class DBhelperOracle {
 Connection con=null;
 ResultSet res=null;
// PreparedStatement pre=null;
 PreparedStatement pre=null;
 
 //连接数据库
 public void DBbase(){
     try {

//        String url="jdbc:oracle:thin:@192.168.224.87:1523:orcl";
//        String userName="gb";
//        String passWord="gb123$";
        
        String url="jdbc:oracle:thin:@192.168.31.35:1521:orcl";
        String userName="gb_hospital";
        String passWord="gb_hospital123$";
            
        Class.forName(driver);
        con=DriverManager.getConnection(url,userName,passWord);
    } catch (Exception e) {
        e.printStackTrace();
    }
 }
 
 //查询
 public ResultSet Search(String sql,String args[]){
     DBbase();
     try {
        pre=con.prepareStatement(sql);
        if(args!=null){
            for(int i=0;i<args.length;i++){

 }
 
 //批量增删改（连接一次数据库）
 public int Adu(String sql,String args[]){
     int falg=0;

        String[] str={
