Excel表中的数据导入mysql数据库
1,
à拷贝jar包
Jxl.jar/mysql.jar
2,à添加数据库的操作类src/com.chen.toolsbean

同包内的配置文件
dbinfo.properties
# key
username=root
password=

要转到数据的表信息
package com.chen.domain;
public class Person {
private int id;
private String name;
private String sex;
private String jiguan;
private int age;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getJiguan() {
return jiguan;
}
public void setJiguan(String jiguan) {
this.jiguan = jiguan;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
读取Excel表的数据：
package com.chen.tomysql;
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.List;
import jxl.Sheet;
import jxl.Workbook;
import com.chen.domain.Person;
public class Excel {
public List<Person> addCustomerAssign(File file) {
List<Person> ls = new ArrayList<Person>();
jxl.Workbook rwb = null;
try {
InputStream is = new FileInputStream(file);
rwb = Workbook.getWorkbook(is);
Sheet rs = rwb.getSheet(0);
int rsRows = rs.getRows();
for (int i = 1; i < rsRows; i++) {
// 如第一行为属性项则从第二行开始取数据(int i=0 ;i<rsRows;i++)
String cell1 = rs.getCell(0, i).getContents() + " ";
String cell2 = rs.getCell(1, i).getContents() + " ";
String cell3 = rs.getCell(2, i).getContents() + " ";
String cell4 = rs.getCell(3, i).getContents() + " ";
if (cell1 != null && !cell1.equals(" ") && cell2 != null
&& !cell3.equals(" ") && !cell4.equals(" ")) {
Person person = new Person();
person.setName(rs.getCell(0, i).getContents());
person.setSex(rs.getCell(1, i).getContents());
person.setJiguan(rs.getCell(2, i).getContents());
person.setAge(Integer.parseInt(rs.getCell(3, i)
.getContents()));
ls.add(person);
}
}
System.out.println("取得信息！");
} catch (Exception e) {
e.printStackTrace();
} finally {
rwb.close();
}
return ls;
}
}
把Excel表中的数据写到Mysql中的类：
package com.chen.tomysql;
import com.chen.domain.Person;
import com.chen.toolsbean.SqlHelper;
public class ExcelToMysql {
public static Boolean insertMysql(Person person) {
System.out.println("调取插入信息的方法！");
String sql = "insert into Person(name,sex,jiguan,age) values(?,?,?,?)";
String[] parameters = { person.getName(), person.getSex(),
person.getJiguan(), person.getAge() + "" };
boolean flag = false;
try {
SqlHelper.executeUpdate(sql, parameters);
System.out.println("插入信息!");
flag = true;
} catch (Exception e) {
e.printStackTrace();
} finally {
}
return flag;
}
}
测试类：(其中J:\\Person.xls文件内容：

sex |
jiguan |

Mysql数据库中Person表的字段
package com.chen.tomysql;
import java.io.File;
import java.util.Iterator;
import java.util.List;
import org.junit.Test;
import com.chen.domain.Person;
public class ExcelToMysqlTest {
@Test
public void test() throws Exception {
Excel excel = new Excel();
List<Person> list = excel.addCustomerAssign(new File("J:\\Person.xls"));
Iterator<Person> iter = list.iterator();
System.out.println(iter.hasNext());
while (iter.hasNext()) {
Person person = iter.next();
if (ExcelToMysql.insertMysql(person)) {
System.out.println("Success!");
} else {
System.out.println("Fail!");
}
}
}
}
