AdminController.java

package com.haijunyin.layuidemo.permission.controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RestController; @RestController @RequestMapping(value = "admin") public class AdminController { @RequestMapping(value = "list" method = RequestMethod.GET) public String list(){ return "权限List测试"; } }

LoginController.java

package com.haijunyin.layuidemo.permission.controller; import com.haijunyin.layuidemo.permission.module.AdminUserInfo; import com.haijunyin.layuidemo.permission.services.AdminUserService; 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.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpSession; @Controller public class LoginController { @Autowired private AdminUserService adminUserService; /** * 设置默认打开地址http://localhost:8020的跳转(需要在拦截器中排除) * 1.已登录，跳转到index.html，把adminUserInfo返回前端渲染 * 2.未登录，跳转到登录页 */ @RequestMapping(value = "/" method = RequestMethod.GET) public String index(HttpServletRequest request ModelMap modelMap){ HttpSession session = request.getSession(); AdminUserInfo adminUserInfo = (AdminUserInfo) session.getAttribute("adminUserInfo"); if(null != adminUserInfo){ modelMap.addAttribute("adminUserInfo" adminUserInfo); return "index"; }else{ return "login"; } } /** * 登录(需要在拦截器中排除) * 1.已登录，跳转到index.html，把adminUserInfo返回前端渲染 * 2.未登录，验证密码，如果密码正确，跳转到index.html 则把用户信息放入session，并把adminUserInfo返回前端渲染 * 如果密码错误，跳转到login.html */ @RequestMapping(value = "/login" method = RequestMethod.GET) public String login(@RequestParam(value = "userName" required = false) String userName @RequestParam(value = "userPwd" required = false) String userPwd @RequestParam(value = "verifyCode" required = false) String verifyCode HttpServletRequest request ModelMap modelMap){ //先验证session，再验证密码 HttpSession session = request.getSession(); AdminUserInfo adminUserInfo = (AdminUserInfo) session.getAttribute("adminUserInfo"); if(null != adminUserInfo){ modelMap.addAttribute("adminUserInfo" adminUserInfo); return "index"; }else{ //验证密码 AdminUserInfo adminUserInfo0 = adminUserService.findByUserName(userName); System.out.println("验证登录...userName=" userName "userPwd=" userPwd "verifyCode=" verifyCode); if(adminUserInfo0.getUserPwd().equals(userPwd)){ //用户信息放入session System.out.println("登录...成功..."

"用户名：" userName); return "login"; } } } }

LoginInterceptor.java，登录拦截器，用于拦截处理登录和为登录状态下的ajax请求

package com.haijunyin.layuidemo.permission.interceptor; import com.haijunyin.layuidemo.permission.module.AdminUserInfo; import org.springframework.stereotype.Service; import org.springframework.web.servlet.handler.HandlerInterceptorAdapter; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpSession; @Service public class LoginInterceptor extends HandlerInterceptorAdapter{ @Override public boolean preHandle(HttpServletRequest request HttpServletResponse response Object handler) throws Exception { HttpSession session = request.getSession(); AdminUserInfo adminUserInfo = (AdminUserInfo) session.getAttribute("adminUserInfo"); //未登录去登录 if(null == adminUserInfo){ //注意：这里需要写上"/login"，而不是"login"，否则重定向的地址只会替换最后一个"/"后面的字符串 response.sendRedirect("/login"); } return true; } }

AdminMenuInfo.java，子菜单信息，权限需要真正控制的信息

package com.haijunyin.layuidemo.permission.module; public class AdminMenuInfo { /** 子菜单唯一ID，在页面上面会以它做唯一区分的，对应到相应子窗口的lay-id属性 */ private String filterId; /** 子菜单名，对应子窗口的title */ private String menuName; /** 子菜单URL，对应子窗口的链接html，点击子菜单后，会打开一个iframe并链接到此url */ private String menuUrl; public AdminMenuInfo(){ } public AdminMenuInfo(String filterId String menuName String menuUrl){ this.filterId = filterId; this.menuName = menuName; this.menuUrl = menuUrl; } public String getFilterId() { return filterId; } public void setFilterId(String filterId) { this.filterId = filterId; } public String getMenuName() { return menuName; } public void setMenuName(String menuName) { this.menuName = menuName; } public String getMenuUrl() { return menuUrl; } public void setMenuUrl(String menuUrl) { this.menuUrl = menuUrl; } }

AdminParentInfo.java，父菜单信息

package com.haijunyin.layuidemo.permission.module; import java.util.List; public class AdminParentMenuInfo { private String parentMenuName; private List<AdminMenuInfo> adminMenuInfos; public AdminParentMenuInfo(){ } public AdminParentMenuInfo(String parentMenuName List<AdminMenuInfo> adminMenuInfos){ this.parentMenuName = parentMenuName; this.adminMenuInfos = adminMenuInfos; } public String getParentMenuName() { return parentMenuName; } public void setParentMenuName(String parentMenuName) { this.parentMenuName = parentMenuName; } public List<AdminMenuInfo> getAdminMenuInfos() { return adminMenuInfos; } public void setAdminMenuInfos(List<AdminMenuInfo> adminMenuInfos) { this.adminMenuInfos = adminMenuInfos; } }

AdminUserInfo.java，用户信息，用户登陆后会放入session

package com.haijunyin.layuidemo.permission.module; import java.util.List; public class AdminUserInfo { private long id; private String userName; private String userPwd; private List<AdminParentMenuInfo> adminParentMenuInfos; public long getId() { return id; } public void setId(long id) { this.id = id; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getUserPwd() { return userPwd; } public void setUserPwd(String userPwd) { this.userPwd = userPwd; } public List<AdminParentMenuInfo> getAdminParentMenuInfos() { return adminParentMenuInfos; } public void setAdminParentMenuInfos(List<AdminParentMenuInfo> adminParentMenuInfos) { this.adminParentMenuInfos = adminParentMenuInfos; } }

AdminUserService.java

package com.haijunyin.layuidemo.permission.services; import com.haijunyin.layuidemo.permission.module.AdminUserInfo; public interface AdminUserService { AdminUserInfo findByUserName(String userName); }

AdminUserServiceImpl.java，用户登陆信息加载，实际开发过程中，信息都是从数据库中读取的，设计用户-角色-资源的模型结构，本文不做叙述，

package com.haijunyin.layuidemo.permission.services.impl; import com.haijunyin.layuidemo.permission.module.AdminMenuInfo; import com.haijunyin.layuidemo.permission.module.AdminParentMenuInfo; import com.haijunyin.layuidemo.permission.module.AdminUserInfo; import com.haijunyin.layuidemo.permission.services.AdminUserService; import org.springframework.stereotype.Service; import java.util.ArrayList; import java.util.List; @Service public class AdminUserServiceImpl implements AdminUserService { @Override public AdminUserInfo findByUserName(String userName) { AdminUserInfo userInfo = new AdminUserInfo(); userInfo.setId(1); userInfo.setUserName("yhj"); userInfo.setUserPwd("123456"); List<AdminParentMenuInfo> adminParentMenuInfos = new ArrayList<>(); //权限管理 List<AdminMenuInfo> adminMenuInfos1 = new ArrayList<>(); AdminMenuInfo adminMenuInfo1 = new AdminMenuInfo("filter1" "用户" "admin/admin_user_list.html"); adminMenuInfos1.add(adminMenuInfo1); AdminMenuInfo adminMenuInfo2 = new AdminMenuInfo("filter2" "角色" "admin/admin_role_list.html"); adminMenuInfos1.add(adminMenuInfo2); AdminParentMenuInfo adminParentMenuInfo1 = new AdminParentMenuInfo("权限管理" adminMenuInfos1); adminParentMenuInfos.add(adminParentMenuInfo1); //订单管理 List<AdminMenuInfo> adminMenuInfos2 = new ArrayList<>(); AdminMenuInfo adminMenuInfo11 = new AdminMenuInfo("filter3" "订单列表" "order/order_list.html"); adminMenuInfos2.add(adminMenuInfo11); AdminMenuInfo adminMenuInfo22 = new AdminMenuInfo("filter4" "订单推送" "order/order_send.html"); adminMenuInfos2.add(adminMenuInfo22); AdminParentMenuInfo adminParentMenuInfo2 = new AdminParentMenuInfo("订单管理" adminMenuInfos2); adminParentMenuInfos.add(adminParentMenuInfo2); userInfo.setAdminParentMenuInfos(adminParentMenuInfos); return userInfo; } }
