044 registered users complete the registration function function 04--

Implement user registration function, the user needs to be stored encrypted password using MD5 encryption, the encryption process using a random code salt as salt. Also the need for short codes input by the user for verification.

1. Interfaces

(1) Path Interface:

 

POST /register

 

(2) returns the result:

No return value.

status code:

• 201: Registration successful

• 400: The parameter is incorrect, the registration fails

• 500: Internal Server exceptions, failed to register

(3) basic logic:

• 1) check codes SMS

• 2) salt formation

• 3) to encrypt the password

• 4) into the database

• 5) Delete Redis verification code

2.UserController

/ ** 
     * Register 
     * @param User receives user object information (form submission form, user object reception) 
     * @param code received form parameters - phone code 
     * @return 
     * / 
    @PostMapping ( "Register" )
     public ResponseEntity < void> Register (the User User, @RequestParam ( "code" ) String code) { 
        Boolean Boo = the this .userService.register (User, code);
         IF (Boo == null ! || Boo) {
             return ResponseEntity.status (HttpStatus .BAD_REQUEST) .build (); 
        } 
        return  new new ResponseEntity <>(HttpStatus.CREATED);
    }

3.UserService

 

/ ** 
     * Function Register 
     * @param User 
     * @param code 
     * @return 
     * / 
    public Boolean Register (the User User, String code) {
         // check message authentication code 
        String = cacheCode the this .redisTemplate.opsForValue (). GET (+ key_prefix user.getPhone ());
         IF (! StringUtils.equals (code, cacheCode)) {
             return  to false ; 
        } 

        // salt formation 
        String salt = CodecUtils.generateSalt (); 
        user.setSalt (salt); 

        // for password encryption
        user.setPassword (CodecUtils.md5Hex (user.getPassword (), Salt)); 

        // mandatory parameter settings are not specified null 
        user.setId ( null ); 
        user.setCreated ( new new a Date ());
         // add to the database 
        Boolean B = the this .userMapper.insertSelective (User) ==. 1 ; 

        IF (B) {
             // registered, redis delete records in 
            the this .redisTemplate.delete (key_prefix + user.getPhone ()); 
        } 
        return B; 
    }

The encryption tools requires apache Kit:
