SpringBoot实战项目（七）--用户新增功能之后台存储

前面实现了对用户名，电话，邮箱的验证后需要把信息存储到数据库中...

这里涉及到两张表--sys_user(用户表)，sys_user_role(用户角色关联表)

从控制器写起--UserController

 1     /**
 2      * 用户新增功能实现
 3      * @param sysUser
 4      * @param roleId
 5      * @return
 6      */
 7     @PostMapping("/add")
 8     @ResponseBody
 9     public Results<SysUser> save(SysUser sysUser,Integer roleId) {
10        List<SysUser> results = userService.getUser(sysUser.getUserName(),sysUser.getTelephone(),sysUser.getEmail());
11        if (results != null && results.size()>0){
12            for (SysUser user : results){
13                //判断用户名是否已存在
14                 if (user.getUserName().equals(sysUser.getUserName())){
15                         return Results.failure(ResponseCode.USERNAME_REPEAT.getCode(), ResponseCode.USERNAME_REPEAT.getMessage());
16                     }
17                      //判断手机号是否已存在
18                     if (user.getTelephone().equals(sysUser.getTelephone())) {
19                         return Results.failure(ResponseCode.PHONE_REPEAT.getCode(), ResponseCode.PHONE_REPEAT.getMessage());
20                     }
21                     //判断邮箱是否已存在
22                     if (user.getEmail().equals(sysUser.getEmail())) {
23                         return Results.failure(ResponseCode.EMAIL_REPEAT.getCode(), ResponseCode.EMAIL_REPEAT.getMessage());
24                     }
25            }
26        }
27        sysUser.setStatus(1);
28        //MD5加密
29        sysUser.setPassWord(Md5Cipher.encrypt(sysUser.getPassWord()));
30             return userService.save(sysUser,roleId);
31     }

sysUser--页面接收的user信息，roleId--所选择的角色的id,注意Status(状态在数据库中不能为空，1 代表启用，可以手动设置)，密码使用MD5加密
