java 解析 excel數據並將數據插入mysql

1. 創建解析主程序,代碼如下:

package com.java.parseExcel;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.text.DecimalFormat;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.LinkedList;
import java.util.List;

import org.apache.poi.ss.usermodel.Cell;

import org.apache.poi.ss.usermodel.DateUtil;
import org.apache.poi.ss.usermodel.Row;

import org.apache.poi.ss.usermodel.WorkbookFactory;

import com.java.bean.CallListInfoBean;

public class ExcelParse {
	private Sheet sheet; // 表格類實例
	@SuppressWarnings("rawtypes")
    LinkedList[] result; // 保存每個單元格的數據 ，使用的是一種鏈表數組的結構

        init();
        
        //判斷是何種格式的Excel文件，主要是表頭，數據格式不同，解析字段方式不一樣
        LinkedList reList =  result[0];

        }
        return list;
    }
	
	// 讀取excel文件，創建表格實例
	private void loadExcel(InputStream is) {

				}
				break;
			case Cell.CELL_TYPE_STRING:

			default:

				break;
			}
		}
		return cellValue.trim();
	}
   
	
	// 初始化表格中的每一行，並得到每一個單元格的值
	@SuppressWarnings({ "rawtypes", "unchecked" })
    public void init() {
		int rowNum = sheet.getLastRowNum() + 1;
		result = new LinkedList[rowNum];
		for (int i = 0; i < rowNum; i++) {
			Row row = sheet.getRow(i);

			result[i] = new LinkedList();
			for (int j = 0; j < row.getLastCellNum(); j++) {

2. 創建對應的mysql相關bean

package com.java.bean;

public class CallListBean {
	/**用戶姓名*/
	private String name;
	/**用戶電話號碼*/
	private String localNum;
	/**通話開始時間*/
	private String startTime;
	/**通信地點*/
	private String position;
	/**通信方式*/
	private String method;
	/**對方號碼*/
	private String dialNumber;
	/**通信時長*/
	private String callDuration;
	private String file_download_url;
	private String caseID;
	/**通話日期*/
	private String day; 
	/**通話時間*/
	private String time;
	public CallListBean(){
		
	}
	public CallListBean(String name, String localNum,String startTime, String position, String method,
			String dialNumber,String callDuration,String file_download_url,String caseID,String day,String time) {
		this.name = name;
		this.localNum = localNum;
		this.startTime = startTime;
		this.position = position;
		this.method = method;
		this.dialNumber = dialNumber;
		this.callDuration = callDuration;
		this.file_download_url = file_download_url;
		this.caseID = caseID;
		this.day = day;
		this.time = time;
	}

	public String getCaseID() {
		return caseID;
	}
	public void setCaseID(String caseID) {
		this.caseID = caseID;
	}
	public String getFile_download_url() {
		return file_download_url;
	}
	public void setFile_download_url(String file_download_url) {
		this.file_download_url = file_download_url;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getLocalNum() {
		return localNum;
	}
	public void setLocalNum(String localNum) {
		this.localNum = localNum;
	}
	public String getStartTime() {
		return startTime;
	}
	public void setStartTime(String startTime) {
		this.startTime = startTime;
	}
	public String getPosition() {
		return position;
	}
	public void setPosition(String position) {
		this.position = position;
	}
	public String getMethod() {
		return method;
	}
	public void setMethod(String method) {
		this.method = method;
	}
	public String getDialNumber() {
		return dialNumber;
	}
	public void setDialNumber(String dialNumber) {
		this.dialNumber = dialNumber;
	}
	public String getCallDuration() {
		return callDuration;
	}
	public void setCallDuration(String callDuration) {
		this.callDuration = callDuration;
	}
	
	public String getDay() {
		return day;
	}
	public void setDay(String day) {
		this.day = day;
	}
	public String getTime() {
		return time;
	}
	public void setTime(String time) {
		this.time = time;
	}
	@Override
	public String toString() {
		return "CallListBean [name=" + name + ", localNum=" + localNum
				+ ", startTime=" + startTime + ", position=" + position
				+ ", method=" + method + ", dialNumber=" + dialNumber
				+ ", callDuration=" + callDuration + ", file_download_url="
				+ file_download_url + ", caseID=" + caseID + ", day=" + day
				+ ", time=" + time + "]";
	}
}

3. 創建日期解析類

package com.java.parseExcel;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.GregorianCalendar;

public class ParserDateUtil {
	/**
	 * @param dateStr
	 * @return 獲取當前是星期幾
	 */
	public static String getCurrentWeekOfMonth(String dateStr) {

		String weekStr = "";
		int year = 0, month = 0, day = 0;
		try {
			String[] year_month_day = null;
			if (dateStr.split("/").length>1) {
			    year_month_day = dateStr.split("/");
			} else if (dateStr.split("-").length>1) {
			    year_month_day = dateStr.split("-");
			}
			
			if (!"".equals(year_month_day[0])) {
				year = Integer.parseInt(year_month_day[0]);
			}
			if (!"".equals(year_month_day[1])) {
				month = Integer.parseInt(year_month_day[1]);
			}
			if (!"".equals(year_month_day[2])) {
				day = Integer.parseInt(year_month_day[2]);
			}
			Calendar calendar = new GregorianCalendar(year, month - 1, day);
			weekStr = getCurrentWeekOfMonth(calendar);
		} catch (Exception e) {
			e.printStackTrace();
		}
		return weekStr;
	}

	/**
	 * @param calendar
	 * @return 獲取當前是星期幾;
	 */
	public static String getCurrentWeekOfMonth(Calendar calendar) {
		String strWeek = "";
		int dw = calendar.get(Calendar.DAY_OF_WEEK);
		if (dw == 1) {
			strWeek = "SUN";
		} else if (dw == 2) {
			strWeek = "MON";
		} else if (dw == 3) {
			strWeek = "TUE";
		} else if (dw == 4) {
			strWeek = "WED";
		} else if (dw == 5) {
			strWeek = "THU";
		} else if (dw == 6) {
			strWeek = "FRI";
		} else if (dw == 7) {
			strWeek = "SAT";
		}
		return strWeek;
	}

	/**
	 * @param calendar
	 * @return 返回當前是星期幾;
	 */
	public static int getCurrentWeekOfMonthIndex(Calendar calendar) {
		// System.out.println(calendar.get(Calendar.DAY_OF_WEEK));
		return calendar.get(Calendar.DAY_OF_WEEK);
	}
	
	//字符串轉換成日期格式
	public static String[] getFormatDate(String dateString){
		String[] s = new String[3];
		String date = dateString.trim();
		String year = date.substring(0, 4);
		String month = date.substring(4, 6);
		String day = date.substring(6, 8);
		String hour = date.substring(8, 10);
		String minute = date.substring(10, 12);
		String second = date.substring(12, 14);
		String strDate1 = year+"-"+month+"-"+day+" "+hour+":"+minute+":"+second;
		String strDate2 = year+"-"+month+"-"+day;
		String strDate3 = hour+":"+minute+":"+second;
		s[0] = strDate1;
		s[1] = strDate2;
		s[2] = strDate3;
		return s;
	}

	public static void main(String[] args) {
	    ParserDateUtil pd = new ParserDateUtil();
	    String a = pd.getCurrentWeekOfMonth("2016-11-11");
	    System.out.println(a);
	}
}

4. 最終mysql中輸入如下
