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
