javaWeb校园宿舍管理解析

篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了javaWeb校园宿舍管理解析相关的知识，希望对你有一定的参考价值。
关于3种身份的登录验证已经完成，现在我们开始逐步完成菜单中的选项。
首先看管理员进入系统的菜单选项，第一个是楼宇管理员，看源码关于该功能，只是简单的增删改查，工作中其实往往大多数也是针对实体类的增删改查，无非是持久层技术不同或者企业有大牛将这些方法统一，方便拿来直接用，先看效果页面。
上面一个页面关于楼宇管理员管理包含四个功能：查询（条件查询和全查询）、删除、修改、新增。
首先我们来理清楚思路，管理员身份登录，进入index.jsp页面，我们会发现菜单相应操作都在left.jsp中，首先定位到--楼宇管理者管理
<a href="TeacherManager.action">楼宇管理员管理</a>
从这里我们就知道关于请求，我们首先得配置struts2的action，下面我们在struts.xml中添加
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <package name="strutsqs" extends="struts-default" namespace="/" > <!-- 登录action --> <action name="GoLogin" class="com.action.GoLogin"> <result name="input">/Login.jsp</result> <result name="success">/Index.jsp</result> </action> <!-- 楼宇管理者管理action --> <action name="TeacherManager" class="com.action.TeacherManager"> <result name="success">/TeacherManager.jsp</result> </action> </package> </struts>
增加action类--TeacherManager以及TeacherDao增加查询方法
package com.dao;
import java.util.List;
import com.bean.TeacherBean;
public interface TeacherDao {
/**
* @date 2016-10-18 下午6:03:50
* @Title: CheckLogin
* @Description: 根据用户名称以及密码验证是否存在该管理员账号
* @return String 返回类型
* @throws
*/
public String CheckLogin(TeacherBean teacher);
/**
*
* @date 2016-10-19 下午4:35:52
* @Title: getTeacherList
* @Description: 获取teahcer
* @return List<TeacherBean> 返回类型
* @throws
*/
public List<TeacherBean> getTeacherList(String SearchRow,String Searchkey);
}TeacherDao的实现类TeacherDaoImpl
package com.dao.impl;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import org.apache.ibatis.session.SqlSession;
import com.bean.TeacherBean;
import com.dao.TeacherDao;
import com.utils.SessionFactoryUtil;
public class TeacherDaoImpl implements TeacherDao{
@Override
public String CheckLogin(TeacherBean teacher) {
SqlSession session = SessionFactoryUtil.getSqlSessionFactory().openSession();
Map<String,Object> params = new HashMap<String ,Object>();
params.put("Teacher_Username", teacher.getTeacher_Username());
params.put("Teacher_Password", teacher.getTeacher_Password());
TeacherBean teacherbean = (TeacherBean) session.selectOne("com.mybatis.model.Teacher.selectByUsernameAndPassword", params);
session.close();
if(teacherbean!=null){
return teacherbean.getTeacher_ID()+"";
}
return null;
}
@Override
public List<TeacherBean> getTeacherList(String SearchRow,String Searchkey) {
SqlSession session = SessionFactoryUtil.getSqlSessionFactory().openSession();
Map<String,Object> params = new HashMap<String ,Object>();
params.put("filed", SearchRow);
params.put("value", Searchkey);
List<TeacherBean> teacherbean=session.selectList("com.mybatis.model.Teacher.selectTeacherList",params);
return teacherbean;
}
}当然在少不了在mabatis配置查询语句，这里我用了mybatis的if以及动态列添加，用if来判断是否是条件查询，同时动态传参当列名条件，因此注意map中field的传递需跟表字段保持一致（不区分大小写）
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper

</html>以上关于楼宇管理员查询包含条件查询已经完成，剩下的思路都是一样的，都是先增加action，然后增加dao方法，action需要增加页面的就增加页面，下面我不详细说了，只贴代码。
涉及新增，因此需要创建序列:
CREATE SEQUENCE seq_teacher INCREMENT BY 1 START WITH 1 NOMAXVALUE NOCYCLE CACHE 10;
增加增删改的action配置
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <package name="strutsqs" extends="struts-default" namespace="/" > <!-- 登录action --> <action name="GoLogin" class="com.action.GoLogin"> <result name="input">/Login.jsp</result> <result name="success">/Index.jsp</result> </action> <!-- 楼宇管理者管理action --> <action name="TeacherManager" class="com.action.TeacherManager"> <result name="success">/TeacherManager.jsp</result> </action> <action name="TeacherAddSave" class="com.action.TeacherAddSave"> <result name="success" type="redirect">TeacherManager.action</result> </action> <action name="TeacherDel" class="com.action.TeacherDel"> <result name="success" type="redirect">TeacherManager.action</result> </action> <action name="TeacherUpdate" class="com.action.TeacherUpdate"> <result name="success">/TeacherUpdate.jsp</result> </action> <action name="TeacherUpdateSave" class="com.action.TeacherUpdateSave"> <result name="success" type="redirect">TeacherManager.action</result> </action> </package> </struts>
