一、使用layui框架实现权限登陆显示树形菜单
1、首先引用一下layui框架所需的包
2、创建二星权限显现树形菜单所需要的表和所需要操作的书本类型表
用户表t_xm_user
树形菜单展现所需的权限表 t_book_menu
书本类型表t_book_category2
准备下面代码中所需要的包工具包:

3、权限登陆
userDao类
package com.ht.dao; import java.sql.SQLException; import java.util.List; import java.util.Map; import com.ht.daoimpl.IUserDao; import com.ht.util.JsonBaseDao; import com.ht.util.JsonUtils; import com.ht.util.PageBean; import com.ht.util.StringUtils;public class UserDao extends JsonBaseDao implements IUserDao{ /** * 登陆查询用户表 * @param paMap * @param pageBean * @return * @throws SQLException * @throws IllegalAccessException * @throws InstantiationException */ public List<Map<String,Object>> list(Map<String,String[]> paMap,PageBean pageBean) throws InstantiationException, IllegalAccessException, SQLException{ String sql="select * from t_xm_user where true"; String user_name=JsonUtils.getParamVal(paMap, "user_name"); String user_pwd=JsonUtils.getParamVal(paMap, "user_pwd"); if (StringUtils.isNotBlank(user_name)) { sql= sql +" and user_name ="+user_name; } if (StringUtils.isNotBlank(user_pwd)) { sql= sql +" and user_pwd ="+user_pwd; } return super.executeQuery(sql, pageBean); } /** * 通过中间表查询登陆用户所对应的权限 * @param paMap * @param pageBean * @return * @throws InstantiationException * @throws IllegalAccessException * @throws SQLException */ public List<Map<String,Object>> listMenu(String user_id,PageBean pageBean) throws InstantiationException, IllegalAccessException, SQLException{ String sql="select * from t_usermenuid where true"; if (StringUtils.isNotBlank(user_id)) { sql= sql +" and user_id ="+user_id; } return super.executeQuery(sql, pageBean); } }web层
userAction类
package com.ht.web;import java.util.HashMap;import java.util.List;import java.util.Map;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import com.fasterxml.jackson.databind.ObjectMapper;import com.ht.dao.UserDao;import com.zking.framework.ActionSupport;import com.ht.util.PageBean;import com.ht.util.ResponseUtil;import com.ht.util.StringUtils;public class UserAction extends ActionSupport { private UserDao uesrDao = new UserDao(); public String login(HttpServletRequest req, HttpServletResponse rep) { try { List<Map<String, Object>> list = this.uesrDao.list(req.getParameterMap(), null); if (list != null && list.size() > 0) { List<Map<String, Object>> listmenu = this.uesrDao.listMenu(req.getParameter("user_name"), null); StringBuffer sb = new StringBuffer(); for (Map<String, Object> map : listmenu) { sb.append("," + map.get("Menuid")); } req.getSession().setAttribute("menuhid", sb.substring(1)); return "index"; } } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return "login"; } /** * datagrid所需数据后端程序员开发完毕 * @param req * @param resp * @return */ public String list(HttpServletRequest req,HttpServletResponse resp){ try { PageBean pageBean=new PageBean(); pageBean.setRequest(req); List<Map<String, Object>> list = this.uesrDao.list(req.getParameterMap(), pageBean); ObjectMapper om=new ObjectMapper(); //数据格式转换 Map<String, Object> map=new HashMap<>(); map.put("total", pageBean.getTotal()); map.put("rows", list); ResponseUtil.write(resp, om.writeValueAsString(map)); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return null; } }login.jsp 显示登陆界面

<action path="/userAction" type="com.ht.web.UserAction"> <forward name="login" path="/login.jsp" redirect="false" /> </action>
效果如下：
4、树形菜单显示
对树形菜单的格式进行描述 写一个TreeNode 类
package com.ht.entity; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map;public class TreeNode { private String id; private String name; private Map<String, Object> attributes = new HashMap<>(); private List<TreeNode> children = new ArrayList<>(); public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Map<String, Object> getAttributes() { return attributes; } public void setAttributes(Map<String, Object> attributes) { this.attributes = attributes; } public List<TreeNode> getChildren() { return children; } public void setChildren(List<TreeNode> children) { this.children = children; } public TreeNode(String id, String text, Map<String, Object> attributes, List<TreeNode> children) { super(); this.id = id; this.name = name; this.attributes = attributes; this.children = children; } public TreeNode() { super(); } @Override public String toString() { return "TreeNode [id=" + id + ", name=" + name + ", attributes=" + attributes + ", children=" + children + "]"; } }在dao类中使用了递归来转换josn格式，因为layui只能识别这种格式
package com.ht.dao; import java.sql.SQLException; import java.util.ArrayList; import java.util.HashMap; import java.util.List; import java.util.Map; import com.ht.daoimpl.IMenuDao; import com.ht.entity.TreeNode; import com.ht.util.JsonBaseDao; import com.ht.util.JsonUtils; import com.ht.util.PageBean; import com.ht.util.StringUtils;/** * 树形权限管理类 * @author Administrator * */public class MenuDao extends JsonBaseDao implements IMenuDao{ /** * * @param map req.getParameterMap * @param pageBean 分页 * @return * @throws Exception */ public List<TreeNode> list(Map<String, String[]> map,PageBean pageBean) throws Exception{ List<Map<String, Object>> listMenu=this.listMenuSef(map, pageBean); List<TreeNode> treeNodeList=new ArrayList<>(); menuList2TreeNodeList(listMenu, treeNodeList); return treeNodeList; } /** * 查询子节点 * @param map * @param pageBean * @return * @throws Exception */ public List<Map<String, Object>> listMenuSef(Map<String, String[]> map,PageBean pageBean)throws Exception{ String sql=" select * from t_book_menu where true"; String id=JsonUtils.getParamVal(map, "menuhid"); if(StringUtils.isNotBlank(id)) { sql= sql + " and Menuid in ("+id+")"; } else { sql= sql + " and Menuid =-1"; } return super.executeQuery(sql, pageBean); } /** * 查询Menu表的数据 * @param map * @param pageBean * @return */ public List<Map<String, Object>> listMenu(Map<String, String[]> map,PageBean pageBean)throws Exception{ String sql=" select * from t_book_menu where true"; String id=JsonUtils.getParamVal(map, "id"); if(StringUtils.isNotBlank(id)) { sql= sql + " and parentid ="+id; } else { sql= sql + " and parentid = -1"; } return super.executeQuery(sql, pageBean); } /** * {Menuid:1,....[]} * ->{id:1,....[]} * menu表的数据不符合easyui树形展示的数据格式 * 需要转换成easyui所能识别的数据格式 * @param map * @param reTreeNode * @throws Exception */ public void menu2TreeNode(Map<String, Object> map, TreeNode treeNode) throws Exception { treeNode.setId(map.get("Menuid").toString()); treeNode.setName(map.get("Menuname").toString()); treeNode.setAttributes(map); Map<String, String[]> jspMap=new HashMap<>(); jspMap.put("id", new String[] {treeNode.getId()}); this.listMenu(jspMap, null); List<Map<String, Object>> listMenu=this.listMenu(jspMap, null); List<TreeNode> treeNodeList=new ArrayList<>(); menuList2TreeNodeList(listMenu, treeNodeList); treeNode.setChildren(treeNodeList); } /** * [{Menuid:1,....[]},{Menuid:2,....[]}] * ->[{id:1,....[]},{id:2,....[]}] * @param mapList * @param treeNodeList * @throws Exception */ public void menuList2TreeNodeList(List<Map<String, Object>> mapList, List<TreeNode> treeNodeList)throws Exception { TreeNode treeNode =null; for (Map<String, Object> map : mapList) { treeNode =new TreeNode(); menu2TreeNode(map, treeNode); treeNodeList.add(treeNode); } } }web层
package com.ht.web;import java.io.PrintWriter;import java.sql.SQLException;import java.util.List;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import com.fasterxml.jackson.databind.ObjectMapper;import com.ht.biz.MenuBiz;import com.ht.bizipml.IMenuBiz;import com.ht.dao.MenuDao;import com.ht.entity.TreeNode;import com.zking.framework.ActionSupport;import com.ht.util.ResponseUtil;public class MenuAction extends ActionSupport { private IMenuBiz menuDao = new MenuBiz(); public String treeMenu(HttpServletRequest req, HttpServletResponse response) throws Exception { @SuppressWarnings("unchecked") List<TreeNode> list = this.menuDao.list(req.getParameterMap(), null); ObjectMapper om = new ObjectMapper(); String jsonStr = om.writeValueAsString(list); response.setContentType("text/html;charset=utf-8"); PrintWriter out=response.getWriter(); out.println(jsonStr); out.flush(); out.close(); return null; } }index.jsp 显示树形菜单

<action path="/menuAction" type="com.ht.web.MenuAction"> <forward name="index" path="/index.jsp" redirect="false" /> </action>
效果图：
二、使用layui框架实现增，删，改，查
dao层，从数据库中拿出数据并且对其进行增，删，改，查操作
package com.ht.dao;import java.sql.SQLException;import java.util.List;import java.util.Map;import com.ht.daoimpl.IBooktypeDao;import com.ht.util.JsonBaseDao;import com.ht.util.JsonUtils;import com.ht.util.PageBean;import com.ht.util.StringUtils;/** * 书籍类别管理 * @author Administrator * */public class BooktypeDao extends JsonBaseDao implements IBooktypeDao{ /** * 编辑用户信息 查询书本类型表 * @param paMap * @return * @throws Exception */ public int edit(Map<String, String[]> paMap) throws Exception { String sql = "update t_book_category2 set book_category_name=? where book_category_id=?"; return super.executeUpdate(sql, new String[] { "book_category_name","book_category_id" }, paMap); } /** * 新增 查询书本类型表 * @param paMap * @return * @throws Exception */ public int add(Map<String, String[]> paMap) throws Exception { String sql = "INSERT INTO t_book_category2(book_category_name) VALUES(?)"; return super.executeUpdate(sql, new String[] { "book_category_name" }, paMap); } /** * 删除 查询书本类型表 * @param paMap * @return * @throws Exception */ public int remove(Map<String, String[]> paMap) throws Exception { String sql = "DELETE FROM t_book_category2 WHERE book_category_id=?"; return super.executeUpdate(sql, new String[] { "book_category_id" }, paMap); } /** * 查询的方法 * @param paMap * @param pageBean * @return * @throws InstantiationException * @throws IllegalAccessException * @throws SQLException */ public List<Map<String, Object>> select(Map<String, String[]> paMap, PageBean pageBean) throws InstantiationException, IllegalAccessException, SQLException { String sql = "select * from t_book_category2 where true"; String book_category_name = JsonUtils.getParamVal(paMap, "book_category_name"); if (StringUtils.isNotBlank(book_category_name)) { sql = sql + " and book_category_name like '%" + book_category_name + "%'"; } return super.executeQuery(sql, pageBean); } }web层
BooktypeAction类
package com.ht.web;import java.util.HashMap;import java.util.List;import java.util.Map;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import com.fasterxml.jackson.databind.ObjectMapper;import com.ht.biz.BooktypeBiz;import com.ht.bizipml.IBooktypeBiz;import com.ht.dao.BooktypeDao;import com.zking.framework.ActionSupport;import com.ht.util.PageBean;import com.ht.util.ResponseUtil;public class BooktypeAction extends ActionSupport{ private IBooktypeBiz booktypeDao=new BooktypeBiz(); /** * 查询的请求方法 * @param req * @param resp * @return */ public String select(HttpServletRequest req,HttpServletResponse resp) { try { PageBean pageBean=new PageBean(); pageBean.setRequest(req); List<Map<String, Object>> list = this.booktypeDao.select(req.getParameterMap(), pageBean); ObjectMapper om=new ObjectMapper(); Map<String, Object> map=new HashMap<>(); map.put("total", pageBean.getTotal()); map.put("rows", list); ResponseUtil.write(resp, om.writeValueAsString(map)); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); } return "index"; } /** * form组件提交所需数据后端程序员处理完毕 * @param req * @param resp * @return */ public String edit(HttpServletRequest req,HttpServletResponse resp){ try { int edit = this.booktypeDao.edit(req.getParameterMap()); ObjectMapper om=new ObjectMapper(); ResponseUtil.write(resp, om.writeValueAsString(edit)); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return null; } /** * 新增的请求方法 * @param req * @param resp * @return */ public String add(HttpServletRequest req,HttpServletResponse resp){ try { int add = this.booktypeDao.add(req.getParameterMap()); ObjectMapper om=new ObjectMapper(); ResponseUtil.write(resp, om.writeValueAsString(add)); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return null; } /** * 删除的请求方法 * @param req * @param resp * @return */ public String remove(HttpServletRequest req,HttpServletResponse resp) { try { int remove=this.booktypeDao.remove(req.getParameterMap()); ObjectMapper om=new ObjectMapper(); ResponseUtil.write(resp, om.writeValueAsString(remove)); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); } return null; } }前台代码，用layui框架规划显示的页面
