阅读更多

第八个版本，完成学生的增删改查操作。

 

如果我们的Action直接继承struts的Action，即org.apache.struts.action.Action，则我们需要为每个操作创建一个Action，一共需要创建六个Action：

进入增加学生页面的Action：

/MyStruts08/src/com/coderdream/action/student/AddStudentAction.java

删除学生的Action：
/MyStruts08/src/com/coderdream/action/student/DeleteStudentAction.java

保存学生的Action：
/MyStruts08/src/com/coderdream/action/student/SaveStudentAction.java

显示学生列表的Action：
/MyStruts08/src/com/coderdream/action/student/StudentAction.java

更新已存在学生信息的Action：
/MyStruts08/src/com/coderdream/action/student/UpdateStudentAction.java

进入查看学生信息页面的Action：
/MyStruts08/src/com/coderdream/action/student/ViewStudentAction.java

 

AddStudentAction.java

 

package com.coderdream.action.student;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

public class AddStudentAction extends Action {

	/**
	 * 处理客户端请求
	 */
	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request,
			HttpServletResponse response) throws Exception {

		// StudentDao studentDao = new StudentDao();
		System.out.println("AddStudentAction");

		return mapping.findForward("success");
	}

}

 
DeleteStudentAction.java

 

 

package com.coderdream.action.student;

import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import com.coderdream.db.StudentDao;
import com.coderdream.form.StudentForm;

public class DeleteStudentAction extends Action {

	/**
	 * 处理客户端请求
	 */
	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request,
			HttpServletResponse response) throws Exception {

		// 得到学生的学号
		StudentForm studentForm = (StudentForm) form;
		String sno = studentForm.getNo();
		System.out.println("sno: " + sno);

		// 删除学生
		StudentDao studentDao = new StudentDao();
		int result = studentDao.deleteStudent(sno);
		System.out.println("Delete Result: " + result);

		// 查询最新的学生列表
		List<StudentForm> studentFormList = studentDao.quertAllStudent();
		request.setAttribute("studentFormList", studentFormList);

		return mapping.findForward("success");
	}

}

 
SaveStudentAction.java

public class SaveStudentAction extends Action {

	/**

		studentForm.setName(studentForm.getName());
		studentForm.setSex(studentForm.getSex());

同时，增加一个首页，用于导航不同的模块，如：学生列表、课程课程等等，对应的Action为IndexAction。

IndexAction.java

package com.coderdream.action;

import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

public class IndexAction extends Action {

	/**
	 * 处理客户端请求
	 */
	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request,
			HttpServletResponse response) throws Exception {
		return mapping.findForward("success");
	}

}
