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
