将之前写好的ssm复制，重新命名为myecpbm，然后修改相关文件名和配置，文件目录结构和要修改的项目名如下图一
图一
1、选中改文件，Window==>show view==>Navigator
2、pom.xml文件
3、web==>WEB-INF==>dispatcherServlet-servlet.xml下
4、到次修改完毕
验证登录，成功证明前面的配置完成了
开始搭建
1、在com.myecpbm.pojo包中，创建实体类 AdminInfo
package com.myecpbm.pojo;import java.util.List;public class AdminInfo {private int id;private String name;private String pwd;// 关联的属性private List<Functions> fs;public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPwd() {return pwd;}public void setPwd(String pwd) {this.pwd = pwd;}public List<Functions> getFs() {return fs;}public void setFs(List<Functions> fs) {this.fs = fs;}}
2、 在com.myecpbm.pojo包中，创建实体类 Funcions
package com.myecpbm.pojo;import java.util.HashSet;import java.util.Set;public class Functions implements Comparable<Functions> {private int id;private String name;private int parentid;private boolean isleaf;// 关联的属性private Set ais = new HashSet();public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public int getParentid() {return parentid;}public void setParentid(int parentid) {this.parentid = parentid;}public boolean isIsleaf() {return isleaf;}public void setIsleaf(boolean isleaf) {this.isleaf = isleaf;}public Set getAis() {return ais;}public void setAis(Set ais) {this.ais = ais;}// @Overridepublic int compareTo(Functions arg0) {return ((Integer) this.getId()).compareTo((Integer) (arg0.getId()));}// 比较2个ID，相同时返回0，否则返回非0数}
3、再com.myecpbm.dao包中创建接口AdminInfoDao
package com.myecpbm.dao;import org.apache.ibatis.annotations.Many;import org.apache.ibatis.annotations.Result;import org.apache.ibatis.annotations.Results;import org.apache.ibatis.annotations.Select;import org.apache.ibatis.mapping.FetchType;import com.myecpbm.pojo.AdminInfo;public interface AdminInfoDao {// 根据登录名和密码查询管理员@Select("select * from admin_info where name = #{name} and pwd = #{pwd}")public AdminInfo selectByNameAndPwd(AdminInfo ai);// 根据管理员id获取管理员对象及关联的功能集合@Select("select * from admin_info where id = #{id}")@Results({ @Result(id = true, column = "id", property = "id"), @Result(column = "name", property = "name"), @Result(column = "pwd", property = "pwd"),@Result(column = "id", property = "fs", many = @Many(select = "com.myecpbm.dao.FunctionDao.selectByAdminId", fetchType = FetchType.EAGER)) })AdminInfo selectById(Integer id);}
4、再com.myecpbm.dao包中创建接口FunctionDao
package com.myecpbm.dao;import java.util.List;import org.apache.ibatis.annotations.Select;import com.myecpbm.pojo.Functions;public interface FunctionDao {// 根据管理员id,获取功能权限@Select("select * from functions where id in (select fid from powers where aid = #{aid} )")public List<Functions> selectByAdminId(Integer aid);}
5、在com.myecpbm.service包中，创建业务逻辑层接口AdminInfoService
package com.myecpbm.service;import com.myecpbm.pojo.AdminInfo;public interface AdminInfoService {// 登录验证public AdminInfo login(AdminInfo ai);// 根据管理员编号，获取管理员对象及关联的功能权限public AdminInfo getAdminInfoAndFunctions(Integer id);}
6、在com.myecpbm.service.impl包中，创建接口实现类AdminInfoServiceImpl
package com.myecpbm.service.impl;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Isolation;import org.springframework.transaction.annotation.Propagation;import org.springframework.transaction.annotation.Transactional;import com.myecpbm.dao.AdminInfoDao;import com.myecpbm.pojo.AdminInfo;import com.myecpbm.service.AdminInfoService;@Service("adminInfoService")@Transactional(propagation = Propagation.REQUIRED, isolation = Isolation.DEFAULT)public class AdminInfoServiceImpl implements AdminInfoService {@Autowiredprivate AdminInfoDao adminInfoDao;// @Overridepublic AdminInfo login(AdminInfo ai) {return adminInfoDao.selectByNameAndPwd(ai);}// @Overridepublic AdminInfo getAdminInfoAndFunctions(Integer id) {return adminInfoDao.selectById(id);}}
7、在webapp根目录下创建admin_login.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%><html><head><title>电子商务平台——后台登录页</title><!-- 引入EasyUI的相关css和js文件 --><link href="EasyUI/themes/default/easyui.css" rel="stylesheet"type="text/css" /><link href="EasyUI/themes/icon.css" rel="stylesheet" type="text/css" /><link href="EasyUI/demo.css" rel="stylesheet" type="text/css" /><script src="EasyUI/jquery.min.js" type="text/javascript"></script><script src="EasyUI/jquery.easyui.min.js" type="text/javascript"></script><script src="EasyUI/easyui-lang-zh_CN.js" type="text/javascript"></script></head><body><script type="text/javascript">function clearForm() {$('#adminLoginForm').form('clear');}function checkAdminLogin() {$("#adminLoginForm").form("submit", {// 向控制器类AdminInfoController中login方法发送请求url : 'admininfo/login', success : function(result) {//处理返回success的回调函数var result = eval('(' + result + ')');//将字符串result转换为表达式if (result.success == 'true') {window.location.href = 'admin.jsp';$("#adminLoginDlg").dialog("close");} else {$.messager.show({title : "提示信息",msg : result.message});}}});}</script><div id="adminLoginDlg" class="easyui-dialog"style="left: 550px; top: 200px;width: 300;height: 200"data-options="title:'后台登录',buttons:'#bb',modal:true"><form id="adminLoginForm" method="post"><table style="margin:20px;font-size: 13;"><tr><th >用户名</th><td><input class="easyui-textbox" type="text" id="name"name="name" data-options="required:true" value="admin"></input></td></tr><tr><th>密码</th><td><input class="easyui-textbox" type="text" id="pwd"name="pwd" data-options="required:true" value="123456"></input></td></tr></table></form></div><div id="bb"><a href="javascript:void(0)" class="easyui-linkbutton"onclick="checkAdminLogin()">登录</a> <a href="javascript:void(0)"class="easyui-linkbutton" onclick="clearForm();">重置</a></div></body></html>
8、在com.myecpbm.controller包中创建控制类AdminInfoController
package com.myecpbm.controller;import java.util.ArrayList;import java.util.Collections;import java.util.List;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Controller;import org.springframework.ui.ModelMap;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.bind.annotation.SessionAttributes;import com.myecpbm.pojo.AdminInfo;import com.myecpbm.pojo.Functions;import com.myecpbm.pojo.TreeNode;import com.myecpbm.service.AdminInfoService;import com.myecpbm.util.JsonFactory;@SessionAttributes(value = { "admin" })@Controller@RequestMapping("/admininfo")public class AdminInfoController {@Autowiredprivate AdminInfoService adminInfoService;@RequestMapping(value = "/login", produces = "text/html;charset=UTF-8")@ResponseBodypublic String login(AdminInfo ai, ModelMap model) {// 后台登录验证AdminInfo admininfo = adminInfoService.login(ai);if (admininfo != null && admininfo.getName() != null) {// 验证通过后，再判断是否已为该管理员分配功能权限if (adminInfoService.getAdminInfoAndFunctions(admininfo.getId()).getFs().size() > 0) {// 验证通过且已分配功能权限，则将admininfo对象存入model中model.put("admin", admininfo);// 以JSON格式向页面发送成功信息return "{\"success\":\"true\",\"message\":\"登录成功\"}";} else {return "{\"success\":\"false\",\"message\":\"您没有权限，请联系超级管理员设置权限！\"}";}} elsereturn "{\"success\":\"false\",\"message\":\"登录失败\"}";}@RequestMapping("getTree")@ResponseBodypublic List<TreeNode> getTree(@RequestParam(value = "adminid") String adminid) {// 根据管理员编号，获取AdminInfo对象AdminInfo admininfo = adminInfoService.getAdminInfoAndFunctions(Integer.parseInt(adminid));List<TreeNode> nodes = new ArrayList<TreeNode>();// 获取关联的Functions对象集合List<Functions> functionsList = admininfo.getFs();// 对List<Functions>类型的Functions对象集合排序Collections.sort(functionsList);// 将排序后的Functions对象集合转换到List<TreeNode>类型的列表nodesfor (Functions functions : functionsList) {TreeNode treeNode = new TreeNode();treeNode.setId(functions.getId());treeNode.setFid(functions.getParentid());treeNode.setText(functions.getName());nodes.add(treeNode);}// 调用自定义的工具类JsonFactory的buildtree方法，为nodes列表中的各个TreeNode元素中的// children属性赋值(该节点包含的子节点)List<TreeNode> treeNodes = JsonFactory.buildtree(nodes, 0);return treeNodes;}}
9、在webapp根目录下创建admin.jsp
<%@ page language="java" import="java.util.*" contentType="text/html; charset=utf-8" pageEncoding="utf-8" %><%if (session.getAttribute("admin") == null)response.sendRedirect("/myecpbm/admin_login.jsp");%><html><head><title>后台管理首页面</title><link href="EasyUI/themes/default/easyui.css" rel="stylesheet"type="text/css" /><link href="EasyUI/themes/icon.css" rel="stylesheet" type="text/css" /><link href="EasyUI/demo.css" rel="stylesheet" type="text/css" /><script src="EasyUI/jquery.min.js" type="text/javascript"></script><script src="EasyUI/jquery.easyui.min.js" type="text/javascript"></script><script src="EasyUI/easyui-lang-zh_CN.js" type="text/javascript"></script></head><body class="easyui-layout"><div data-options="region:'north',border:false"style="height: 60px; background: #B3DFDA; padding: 10px"><div align="left"><div style="font-family: Microsoft YaHei; font-size: 16px;">电商平台后台管理系统</div></div><div align="right">欢迎您，<font color="Red">${sessionScope.admin.name}</font></div></div><div data-options="region:'west',split:true,title:'功能菜单'"style="width: 180px"><ul id="tt"></ul></div><div data-options="region:'south',border:false"style="height: 50px; background: #A9FACD; padding: 10px; text-align: center">poweredby miaoyong</div><div data-options="region:'center'"><div id="tabs" data-options="fit:true" class="easyui-tabs"style="width: 500px; height: 250px;"></div></div><script type="text/javascript">// 为tree指定数据$('#tt').tree({url : 'admininfo/getTree?adminid=${sessionScope.admin.id}'});$('#tt').tree({onClick : function(node) {if ("商品列表" == node.text) {if ($('#tabs').tabs('exists', '商品列表')) {$('#tabs').tabs('select', '商品列表');} else {$('#tabs').tabs('add', {title : node.text,href : 'productlist.jsp',closable : true});}} else if ("商品类型列表" == node.text) {if ($('#tabs').tabs('exists', '商品类型列表')) {$('#tabs').tabs('select', '商品类型列表');} else {$('#tabs').tabs('add', {title : node.text,href : 'typelist.jsp',closable : true});}} else if ("查询订单" == node.text) {if ($('#tabs').tabs('exists', '查询订单')) {$('#tabs').tabs('select', '查询订单');} else {$('#tabs').tabs('add', {title : node.text,href : 'searchorder.jsp',closable : true});}} else if ("创建订单" == node.text) {if ($('#tabs').tabs('exists', '创建订单')) {$('#tabs').tabs('select', '创建订单');} else {$('#tabs').tabs('add', {title : node.text,href : 'createorder.jsp',closable : true});}} else if ("客户列表" == node.text) {if ($('#tabs').tabs('exists', '客户列表')) {$('#tabs').tabs('select', '客户列表');} else {$('#tabs').tabs('add', {title : node.text,href : 'userlist.jsp',closable : true});}} else if ("退出系统" == node.text) {$.ajax({url : 'admininfo/logout',success : function(data) {window.location.href = "admin_login.jsp";}})}}});</script></body></html>
10、在com.myecpbm.pojo包中创建TreeNode
package com.myecpbm.pojo;import java.util.List;public class TreeNode {private int id; // 节点idprivate String text; // 节点名称private int fid; // 父节点idprivate List<TreeNode> children; // 包含的子节点// 添加set，get方法public int getId() {return id;}public void setId(int id) {this.id = id;}public String getText() {return text;}public void setText(String text) {this.text = text;}public int getFid() {return fid;}public void setFid(int fid) {this.fid = fid;}public List<TreeNode> getChildren() {return children;}public void setChildren(List<TreeNode> children) {this.children = children;}}
11、创建com.myecpbm.util，并在其中创建JsonFactory
package com.myecpbm.util;import java.util.ArrayList;import java.util.List;import com.myecpbm.pojo.TreeNode;public class JsonFactory {public static List<TreeNode> buildtree(List<TreeNode> nodes, int id) {List<TreeNode> treeNodes = new ArrayList<TreeNode>();for (TreeNode treeNode : nodes) {TreeNode node = new TreeNode();node.setId(treeNode.getId());node.setText(treeNode.getText());if (id == treeNode.getFid()) {// 递给调用buildtree方法给TreeNode中的children属性赋值node.setChildren(buildtree(nodes, node.getId()));treeNodes.add(node);}}return treeNodes;}}
运行admin_login.jsp文件，得到以下结果就成功了
