篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Java SSM 项目实战 day07用户角色关联操作，添加角色，以及添加权限相关的知识，希望对你有一定的参考价值。

1、先查询出这个角色没有的权限信息
2、关联角色与权限信息，主要就是向role_permission 表中插入数据
在这里插入图片描述

一、添加角色

在这里插入图片描述
显示路径地址

1、在UserController当中创建findUserByIdAndAllRole

在这里插入图片描述

 //查询用户以及用户可以添加的角色
    @RequestMapping("/findUserByIdAndAllRole.do")
    public ModelAndView findUserByIdAndAllRole(@RequestParam(name = "id", required = true) String userid) throws Exception {

        ModelAndView mv = new ModelAndView();

        //1、根据用户id查询用户
        UserInfo userInfo = userService.findById(userid);
        //2、根据用户的id查询可以添加的角色
        List<Role> otherRoles = userService.findOtherRole(userid);

        mv.addObject("user", userInfo);
        mv.addObject("roleList", otherRoles);
        
        mv.setViewName("user-role-add");
        return mv;
    }

2、在IUserService接口和实现类，当中创建对应的方法

在这里插入图片描述


    List<Role> findOtherRole(String userid);

在UserServiceImpl当中调用Dao
在这里插入图片描述


    @Override
    public List<Role> findOtherRole(String userid) {
        return userDao.findOtherRole(userid);
    }

在这里插入图片描述

3、在IUserDao当中查询数据

在这里插入图片描述

 @Select("select * from role where id not in (select roleId from users_role where userId = #(userId))")
    List<Role> findOtherRole(String userId);

4、创建user-role-add.jsp

在这里插入图片描述
