项目功能：
此项目分为两个角色：普通用户和管理员。普通用户有登录注册、浏览商品信息、添加购物车、结算订单、查看个人信息、查看个人订单详情等等功能。管理员有管理所有商品信息、管理所有订单信息、管理所有用户信息、查看收益数据图表等等功能。
应用技术：
SpringBoot + VueCli + MySQL + MyBatis + Redis + ElementUI
运行环境：
IntelliJ IDEA2019.3.5 + MySQL5.7+ Redis5.0.5 + JDK1.8 + Maven3.6.3+ Node14.16.1
管理员controller：
@Controller
@RequestMapping("/config")
public class UserController {
@Autowired
UserRoleService userRoleService;
@Autowired
UserService userService;
@Autowired
RoleService roleService;
@RequestMapping("/enableStatus")
@ResponseBody
public String enableStatus(@RequestParam(value = "name") String name){
return userService.enableStatus(name);
}
@RequestMapping("/stopStatus")
@ResponseBody
public String stopStatus(@RequestParam(value = "name") String name){
return userService.stopStatus(name);
}
@RequestMapping("/adminAdd")
public String adminadd(Model model){
List<Role> list = roleService.list();
model.addAttribute("rolelist",list);
return "syspage/admin-add";
}
@RequestMapping("/listUser")
public String list(Model model, Page page){
PageHelper.offsetPage(page.getStart(),page.getCount());//分页查询
List<User> us= userService.list();
int total = (int) new PageInfo<>(us).getTotal();//总条数
page.setTotal(total);
model.addAttribute("us", us);//所有用户
model.addAttribute("total",total);
Map<User,List<Role>> user_roles = new HashMap<>();
//每个用户对应的权限

model.addAttribute("user", user);
//当前拥有的角色
List<Role> roles =roleService.listRoles(user);

}
@RequestMapping("deleteUser")
public String delete(Model model,long id){

return "redirect:listUser";
}
@RequestMapping("updateUser")
public String update(User user, long[] roleIds){

//如果在修改的时候没有设置密码，就表示不改动密码
if(user.getPassword().length()!=0) {

int times = 2;
String algorithmName = "md5";
String encodedPassword = new SimpleHash(algorithmName,password,salt,times).toString();

}
else
user.setPassword(null);
userService.update(user);
return "redirect:listUser";
}
@RequestMapping("addUser")
public String add(User user,long[] roleIds){
String salt = new SecureRandomNumberGenerator().nextBytes().toString();//生成随机数
int times = 2;

String encodedPassword = new SimpleHash(algorithmName,user.getPassword(),salt,times).toString();
User u = new User();
u.setName(user.getName());
u.setPassword(encodedPassword);

u.setStatus(1);
u.setAddress(user.getAddress());
u.setPhone(user.getPhone());
userService.add(u);
userRoleService.setRoles(u,roleIds);
return "redirect:listUser";
}
}管理员角色controler：
@Controller
@RequestMapping("/config")
public class RoleController {
@Autowired
RoleService roleService;
@Autowired
RolePermissionService rolePermissionService;
@Autowired
PermissionService permissionService;
@RequestMapping("/addRoleUI")
public String addRole(){
return "syspage/admin-role-add";
}
@RequestMapping("/listRole")
public String list(Model model, Page page){
PageHelper.offsetPage(page.getStart(),page.getCount());//分页查询
List<Role> rs= roleService.list();
int total = (int) new PageInfo<>(rs).getTotal();//总条数
page.setTotal(total);
model.addAttribute("rs", rs);
model.addAttribute("roleSize",total);
Map<Role,List<Permission>> role_permissions = new HashMap<>();
for (Role role : rs) {
List<Permission> ps = permissionService.list(role);
role_permissions.put(role, ps);
}
model.addAttribute("role_permissions", role_permissions);
return "syspage/admin-role";
}
@RequestMapping("/editRole")
public String list(Model model,long id){
Role role =roleService.get(id);
model.addAttribute("role", role);
//所有权限
List<Permission> ps = permissionService.list();
model.addAttribute("ps", ps);
//当前管理员拥有的权限
List<Permission> currentPermissions = permissionService.list(role);
model.addAttribute("currentPermissions", currentPermissions);
return "syspage/admin-role-edit";
}
@RequestMapping("/updateRole")
public String update(Role role,long[] permissionIds){
rolePermissionService.setPermissions(role, permissionIds);
roleService.update(role);
return "redirect:listRole";
}
@RequestMapping("/addRole")
public String list(Model model,Role role){
roleService.add(role);
return "redirect:listRole";
}
@RequestMapping("/deleteRole")
public String delete(Model model,long id){
roleService.delete(id);
return "redirect:listRole";
}
}订单模块controller：
@Controller
@RequestMapping("/order")
public class OrderController {
@Autowired
OrderService orderService;
@Autowired
OrderItemService orderItemService;
@RequestMapping("/list")
public String list(Model model, Page page){
PageHelper.offsetPage(page.getStart(),page.getCount());
List<Order> os= orderService.list();
int total = (int) new PageInfo<>(os).getTotal();
page.setTotal(total);
//为订单添加订单项数据
orderItemService.fill(os);
model.addAttribute("os", os);
model.addAttribute("page", page);
model.addAttribute("totals", total);
return "ordermodule/order-list";
}
@RequestMapping("/orderDelivery")
public String delivery(Order o){
o.setStatus(2);
orderService.update(o);
return "redirect:list";
}
@RequestMapping("/seeOrderItem")
public String seeOrderItem(int oid,Model model){
Order o = orderService.get(oid);
orderItemService.fill(o);
model.addAttribute("orderItems",o.getOrderItems());
model.addAttribute("total",o.getOrderItems().size());
model.addAttribute("totalPrice",o.getTotal());
return "ordermodule/orderItem-list";
}
