OA项目实战学习（7）——初始化数据&权限配置显示

具体有哪些功能：

初始化数据

• 权限数据。
• 超级管理员。

Installer.java

package cn.xbmu.oa.install;

import javax.annotation.Resource;
import org.apache.commons.codec.digest.DigestUtils;
import org.hibernate.SessionFactory;
import org.hibernate.classic.Session;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;
import cn.xbmu.oa.domain.Privilege;
import cn.xbmu.oa.domain.User;
/**
 * 安装应用程序的时候，就初始化好数据
 * @author Administrator
 *
 */
@Component
public class Installer {
	@Resource
	private SessionFactory sessionFactory;
	@Transactional
	public void install() {
		Session session = sessionFactory.getCurrentSession();

		// =====================================
		// 1.超级管理员
		User user = new User();
		user.setName("超级管理员");
		user.setLoginName("admin");
		user.setPassword(DigestUtils.md5Hex("admin"));// 使用MD5摘要信息 加密
		session.save(user);// 保存
		// 2.权限数据
		Privilege menu, menu1, menu2, menu3, menu4, menu5;
		menu = new Privilege("系统管理", null, "FUNC20082.gif", null);
		menu1 = new Privilege("岗位管理", "roleAction_list", null, menu);
		menu2 = new Privilege("部门管理", "departmentAction_list", null, menu);
		menu3 = new Privilege("用户管理", "userAction_list", null, menu);

		session.save(menu);
		session.save(menu1);
		session.save(menu2);
		session.save(menu3);

		session.save(new Privilege("岗位列表", "roleAction_list", null, menu1));
		session.save(new Privilege("岗位添加", "roleAction_add", null, menu1));
		session.save(new Privilege("岗位删除", "roleAction_delete", null, menu1));
		session.save(new Privilege("岗位修改", "roleAction_edit", null, menu1));

		session.save(new Privilege("部门列表", "departmentAction_list", null, menu2));
		session.save(new Privilege("部门添加", "departmentAction_add", null, menu2));
		session.save(new Privilege("部门删除", "departmentAction_delete", null,menu2));
		session.save(new Privilege("部门修改", "departmentAction_edit", null, menu2));

		session.save(new Privilege("用户列表", "userAction_list", null, menu3));
		session.save(new Privilege("用户添加", "userAction_add", null, menu3));
		session.save(new Privilege("用户删除", "userAction_delete", null, menu3));
		session.save(new Privilege("用户修改", "userAction_edit", null, menu3));
		session.save(new Privilege("用户初始化密码", "userAction_initPassword", null,menu3));

		// -------------------------

		menu = new Privilege("网上交流", null, "FUNC20064.gif", null);
		menu1 = new Privilege("论坛管理", "forumManageAction_list", null, menu);
		menu2 = new Privilege("论坛", "forumAction_list", null, menu);

		session.save(menu);
		session.save(menu1);
		session.save(menu2);

		// -------------------------

		menu = new Privilege("审批流转", null, "FUNC20057.gif", null);
		menu1 = new Privilege("审批流程管理", "processDefinitionAction_list", null,
				menu);
		menu2 = new Privilege("申请模板管理", "applicationTemplateAction_list", null,
				menu);
		menu3 = new Privilege("起草申请", "flowAction_applicationTemplateList",
				null, menu);
		menu4 = new Privilege("待我审批", "flowAction_myTaskList", null, menu);
		menu5 = new Privilege("我的申请查询", "flowAction_myApplicationList", null,
				menu);

		session.save(menu);
		session.save(menu1);
		session.save(menu2);
		session.save(menu3);
		session.save(menu4);
		session.save(menu5);

	}

	public static void main(String[] args) {
		System.out.println("正在执行安装");
		ApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
		Installer installer = (Installer) ac.getBean("installer");
		installer.install();
		System.out.println("安装完毕");
	}
}

可以运行该main方法,就可以将数据初始化的数据添加到数据库中。

但是这种方式，不适合用户使用，因此我们可以在window环境下 ，写一个批处理文件 install.bat ，让用户双击即可进行一键安装应用时并初始化数据。

install.bat

如果在Linux系统下。

工程结构:

  

完成设置权限页面：

/xbmuoa/WebRoot/WEB-INF/jsp/roleAction/list.jsp

<!--显示数据列表-->
        <tbody id="TableData" class="dataContainer" datakey="roleList">
        	<s:iterator value="roleList">
				<tr class="TableDetail1 template">
					<td>${name} </td>
					<td>${description} </td>
					<td><s:a action="roleAction_delete.action?id=%{id}" onClick="return delConfirm()">删除</s:a>
						<s:a action="roleAction_editUI.action?id=%{id}">修改</s:a>
						<s:a action="roleAction_setPrivilegeUI?id=%{id}" >设置权限</s:a>
					</td>
				</tr>
			</s:iterator>
        </tbody>
