向数据库插入数据第二种方法

<html><body><h1>学生添加</h1><s:form action="student/student_saveStudent" method="post" theme="simple"><br>姓名:<s:textfield name="student.name" label="姓名" required="true"></s:textfield><br>密码:<s:password label="密码" name="student.password" required="true"></s:password><br>年龄:<s:textfield name="student.age" label="年龄" required="true"></s:textfield><br>性别:<s:radio label="性别" name="student.sex" list="#{‘1‘:‘男‘,‘2‘:‘女‘}"></s:radio><br>出生年月:<s:textfield name="student.dte" label="出生年月" onfocus="WdatePicker({dateFmt : ‘yyyy-MM-dd HH:mm:ss‘})" class="Wdate"></s:textfield><br>爱好:<s:checkboxlist label="爱好" name="student.hobby" list="#{‘1‘:‘basketball‘,‘2‘:‘football‘,‘3‘:‘music‘,‘4‘:‘art‘}"></s:checkboxlist><br>省份:<s:select id="addr1" label="省份 " name="province" list="{‘河北省‘,‘山东省‘}"></s:select>城市:<select id="addr2"  name="city"></select><br>地址:<s:textfield label="location" name="student.address" id="addr3"></s:textfield><s:submit value="http://www.mamicode.com/提交"></s:submit></s:form></body></html>

将前台的name都设为student.**

package com.action;import java.io.IOException;import java.util.ArrayList;import java.util.List;import java.util.Map;import javax.servlet.http.HttpServletResponse;import net.sf.json.JSONArray;import org.apache.struts2.ServletActionContext;import com.dao.StudentDao;import com.dao.imp.StudentDaoImp;import com.entity.Sheng;import com.entity.Student;import com.opensymphony.xwork2.ActionContext;import com.opensymphony.xwork2.ActionSupport;public class StudentAction extends ActionSupport{	private StudentDao dao=new StudentDaoImp();	public StudentDao getDao() {		return dao;	}	public void setDao(StudentDao dao) {		this.dao = dao;	}	//new一个dao		private Student student;	//声明一个student对象	public Student getStudent() {		return student;	}	public void setStudent(Student student) {		this.student = student;	}				public String saveStudent(){					dao.saveStudent(student);		return "saveStudent";	}		}

 在后台声明一个student对象   加上get set方法     就会自动得到前台对象的值 

这时候再调用dao.saveStudent(student);将其保存到数据库中即可
