利用dorado實現excel數據上傳到mysql數據庫

    實現過程當中遇到巨多的bug, 初步估計至少20個異常,可是最後仍是實現了. 具體的過程不細說了, 把大概須要注意的幾點說一下

1    基本步驟是:   java代碼讀取excel表中的數據,  dorado中配置mysql的鏈接,   設計對應excel的表,  設計映射表,  

　　其中我遇到的一些坑:    mysql數據庫不支持序列化, 而聯合主鍵又得有主鍵, 至今不知道怎麼處理聯合主鍵, 我是直接添加了一個id做爲主鍵

     保存的時候用了hibernate的save接口, 可是沒法保存到數據庫中, 緣由有幾點:   配置文件沒有<prop key="hibernate.connection.autocommit">true</prop>

　　或者是沒有寫@Transaction註解, 就沒提交

   配置mysql的時候,必定要仔細, 還要導入相應的jar包, 通常classNotFound就是jar包沒有導入的問題

　　數據庫設計的時候,  字段不能有關鍵字 如 desc

　　導入mysql方言的時候hibernate.dialect=org.hibernate.dialect.MySQL5Dialect其中的y是小寫, 寫成大寫就涼了

2　　個人基本代碼以下

實體類,  excel表格中除了沒有id, 別的字段都有,  我開始以name和datee做爲主鍵, 走了不少彎路

@Entity
@Table(name="EXDATA")
public class ExcelEntity {
//private static final long serialVersionUID = 6076304611179489259L;

@Id
@Column(name="id")
private int id;
@Column(name="name")
private String name;
@Column(name = "dept")
private String dept;
@Column(name="datee")
private String datee;
@Column(name = "result")
private String result;
@Column(name = "lateTime")
private String lateTime;
@Column(name = "beforeTime")
private String beforeTime;
@Column(name = "goWork")
private String goWork;
@Column(name = "afterWork")
private String afterWork;
@Column(name = "descc")
private String descc;
@Column(name = "sign")
private String sign;
@Column(name = "deptLeader")
private String deptLeader;
@Column(name = "govLeader")
private String govLeader;

 

繼承自hibernateD的dao類

@Repository
public class ExcelDao extends HibernateDao<ExcelEntity,Integer>{

}

 

實現類

@Component
public class ExcelDemo {
// 注入dao對象
@Resource
public ExcelDao excelDao;

@Transactional
@Expose
public void getAllByExcel(){

List<ExcelEntity> list=new ArrayList<ExcelEntity>();

try{

// 獲取excel表格對象
Workbook rwb=Workbook.getWorkbook(new File("E:\\創新產品事業部12月未正常打卡記錄.xls"));
Sheet rs=rwb.getSheet(0);
int clos=rs.getColumns();//獲得全部的列
int rows=rs.getRows();//獲得全部的行
int index=0;
for (int i =2; i < rows; i++) {//除去表頭,應該從第三行開始
for (int j = 0; j < clos; j++) {
//第一個是列數，第二個是行數
String name=rs.getCell(j++, i).getContents();
String dept=rs.getCell(j++, i).getContents();
String datee=rs.getCell(j++, i).getContents();
String result=rs.getCell(j++, i).getContents();
String lateTime=rs.getCell(j++, i).getContents();
String beforeTime=rs.getCell(j++, i).getContents();
String goWork=rs.getCell(j++, i).getContents();
String afterWork=rs.getCell(j++, i).getContents();
String descc=rs.getCell(j++, i).getContents();
String sign=rs.getCell(j++, i).getContents();
String deptLeader=rs.getCell(j++, i).getContents();
String govLeader=rs.getCell(j++, i).getContents();
// 將一行數據封裝到實體中

ExcelEntity entity=new ExcelEntity();
entity.setAfterWork(afterWork);
entity.setBeforeTime(beforeTime);
entity.setDept(dept);
entity.setDeptLeader(deptLeader);
entity.setdescc(descc);
entity.setGovLeader(govLeader);
entity.setGoWork(goWork);
entity.setLateTime(lateTime);
entity.setResult(result);
entity.setSign(sign);
entity.setName(name);
entity.setDatee(datee);

entity.setId(index++);

list.add(entity);
}
}

}catch(Exception e){
e.printStackTrace();
}


//保存操做
for (ExcelEntity excelEntity : list) {


System.out.println(excelEntity);

excelDao.save(excelEntity);
System.out.println("save執行完畢");

}



}
}

  最後是一些配置文件, 雖然用的少,可是真的重要  app-context.xml,  還有一個配置文件, 是configure.propertiesl就是存放一些屬性供app-context的變量使用,比較簡單

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

隨便附上excel導出的代碼

@Expose
public void getAllBySql(){
/**
* 從數據庫讀取數據
*/

List<ExcelEntity> list=new ArrayList<ExcelEntity>();
list=excelDao.getAll();

// 將數據保存到excel中


//開始寫入excel,建立模型文件頭
String[] titleA = {"id","姓名","部門","日期","考勤結果","遲到時間","早退時間","上班","下班","說明","簽字","領導","老闆"};
//導入的excel的位置
File file = new File("e:/TestFile.xls");
if(file.exists()){
//若是文件存在就刪除
file.delete();
}
try{

file.createNewFile();
//建立工做簿
WritableWorkbook workbookA = Workbook.createWorkbook(file);

WritableSheet sheetA = workbookA.createSheet("sheet1", 0);
Label labelA = null;
//設置列名
for (int i = 0; i < titleA.length; i++) {
labelA = new Label(i,0,titleA[i]);//第0行
sheetA.addCell(labelA);
}
// 設置單元格屬性
WritableCellFormat wc = new WritableCellFormat();
// 設置居中
wc.setAlignment(Alignment.CENTRE);
// 設置邊框線
wc.setBorder(Border.ALL, BorderLineStyle.THIN);

//插入數據
int i=1;//從第二行開始

for (ExcelEntity excelEntity : list) {
int j=0;//從第1列開始

Integer id=excelEntity.getId();

//向特定格子寫入數據
Label label = new Label(j++, i,id.toString(),wc);
sheetA.addCell(label);
Label label01 = new Label(j++, i,excelEntity.getName(),wc);
sheetA.addCell(label01);
Label label02 = new Label(j++, i,excelEntity.getDept(),wc);
sheetA.addCell(label02);
Label label03 = new Label(j++, i,excelEntity.getDatee(),wc);
sheetA.addCell(label03);
Label label04 = new Label(j++, i,excelEntity.getResult(),wc);
sheetA.addCell(label04);
Label label05 = new Label(j++, i,excelEntity.getLateTime(),wc);
sheetA.addCell(label05);
Label label06 = new Label(j++, i,excelEntity.getBeforeTime(),wc);
sheetA.addCell(label06);
Label label07 = new Label(j++, i,excelEntity.getGoWork(),wc);
sheetA.addCell(label07);
Label label09 = new Label(j++, i,excelEntity.getAfterWork(),wc);
sheetA.addCell(label09);
Label label08 = new Label(j++, i,excelEntity.getdescc(),wc);
sheetA.addCell(label08);

i++;
}
workbookA.write();
workbookA.close();

} catch (Exception e) { e.printStackTrace(); System.out.println("文件寫入失敗，報異常..."); }
