本文小编为大家详细介绍"Java怎么实现教室预订管理系统"，内容详细，步骤清晰，细节处理妥当，希望这篇"Java怎么实现教室预订管理系统"文章能帮助大家解决疑惑，下面跟着小编的思路慢慢深入，一起来学习新知识吧。

一、项目运行

环境配置：

Jdk1.8 + Tomcat8.5 + Mysql + HBuilderX（Webstorm也行）+ Eclispe（IntelliJ IDEA,Eclispe,MyEclispe,Sts都支持）。

项目技术：

Spring + SpringBoot+ mybatis + Maven + Vue 等等组成，B/S模式 + Maven管理等等。

用户管理控制器:

/** * 用户管理控制器 */@RequestMapping("/user/")@Controllerpublic class UserController {    @Autowired    private IUserService userService;    @Autowired    private IRoleService roleService;     @Resource    private ProcessEngineConfiguration configuration;    @Resource    private ProcessEngine engine;     @GetMapping("/index")    @ApiOperation("跳转用户页接口")    @PreAuthorize("hasRole('管理员')")    public String index(String menuid,Model model){        List roles = queryAllRole();        model.addAttribute("roles",roles);        model.addAttribute("menuid",menuid);        //用户首页        return "views/user/user_list";    }     @GetMapping("/listpage")    @ApiOperation("查询用户分页数据接口")    @ApiImplicitParams({            @ApiImplicitParam(name = "UserQuery", value = "用户查询对象", defaultValue = "userQuery对象")    })    @ResponseBody    @PreAuthorize("hasRole('管理员')")    public PageList listpage(UserQuery userQuery){        return  userService.listpage(userQuery);

           return ret;        }        if(userService.addUser(user)<=0) {            ret.put("msg", "添加用户失败");            return ret;        }        ret.put("code",0);        ret.put("msg","添加用户成功");        return ret;    }     /**     * 修改用户信息操作     * @param user     * @return     */    @PostMapping("/editSaveUser")    @ApiOperation("修改用户接口")    @PreAuthorize("hasRole('管理员')")    @ResponseBody    public Message editSaveUser(User user){        if(StringUtils.isEmpty(user.getUsername())){          return Message.error("请填写用户名");

角色管理控制层：

@Controllerpublic class RoleController {     @Autowired    private IRoleService roleService;     @Autowired    private IPermissionService permissionService;        @PreAuthorize("hasRole('管理员')")    @ResponseBody    @RequestMapping("/role/doAdd")    public String doAdd(Role role){        //角色添加        return "ok";    }    //添加角色    @RequestMapping("/role/addRole")    @PreAuthorize("hasRole('管理员')")    @ResponseBody    public AjaxResult addRole(Role role){        System.out.println("保存角色...."+role);        try {            roleService.saveRole(role);            return new AjaxResult();        } catch (Exception e) {            e.printStackTrace();            return new AjaxResult("操作失败");        }    }     @PreAuthorize("hasRole('管理员')")    @RequestMapping("/role/index")    public String index(Model model){        List permisisons = permissionService.findAllPermisisons();        model.addAttribute("permissions",permisisons);        //返回角色        return "views/role/role_list";    }     @RequestMapping("/role/listpage")    @ResponseBody    public PageList listpage(RoleQuery roleQuery){        System.out.println("传递参数:"+roleQuery);        return  roleService.listpage(roleQuery);    }      //修改用户editSaveUser    @RequestMapping("/role/editSaveRole")    @ResponseBody    public AjaxResult editSaveRole(Role role){        System.out.println("修改角色...."+role);        try {            roleService.editSaveRole(role);            return new AjaxResult();        } catch (Exception e) {            e.printStackTrace();        }        return new AjaxResult("修改失败");    }     //添加角色    @RequestMapping("/role/deleteRole")    @ResponseBody    public AjaxResult deleteRole(Long id){        System.out.println("删除角色...."+id);        AjaxResult ajaxResult = new AjaxResult();        try {            roleService.deleteRole(id);        } catch (Exception e) {            e.printStackTrace();            return new AjaxResult("删除失败");        }        return ajaxResult;    }     //添加角色权限 addRolePermission    @RequestMapping("/role/addRolePermission")    @ResponseBody    public AjaxResult addRolePermission(@RequestBody Map paramMap){        AjaxResult ajaxResult = new AjaxResult();        String roleId = (String)paramMap.get("roleId");        List permissionIds = (List) paramMap.get("permissionIds");        try {            //添加角色对应的权限            roleService.addRolePermission(roleId,permissionIds);            return ajaxResult;        }catch (Exception e){            e.printStackTrace();            return new AjaxResult("保存权限失败");        }     } }
