1.otp驗(yàn)證碼獲取

   //用戶獲取otp短信接口
    @RequestMapping(value = "/getotp",method = {RequestMethod.POST}, consumes = {CONTENT_TYPE_FORMED})
    @ResponseBody
    public CommenReturnType getOtp(@RequestParam(name="telphone") String telphone){
        //1. 按照一定的規(guī)則生成OPT驗(yàn)證碼
        Random random = new Random();
        int randomInt = random.nextInt(99999);// [0,99999)
        randomInt += 10000;   //  [10000,109999]
        String otpCode = String.valueOf(randomInt);

        //2. 將OPT驗(yàn)證碼與用戶手機(jī)號相關(guān)聯(lián),使用HttpSession的方式(企業(yè)里使用分布式的Redis)
        httpServletRequest.getSession().setAttribute(telphone,otpCode);


        //3. 將OPT驗(yàn)證碼通過短信通道發(fā)送給用戶,省略（可夠買第三方短信通道，以HTTP Post 方式發(fā)送）
        //企業(yè)里控制臺輸出是用log4j阵面，這里方便調(diào)試轻局，簡單的把驗(yàn)證碼輸入控制臺
        System.out.println("telphone = "+telphone+" & otpCode = "+otpCode);

        return CommenReturnType.create(null);

    }

2.用戶注冊

//用戶注冊接口
    @RequestMapping(value = "/register",method = {RequestMethod.POST}, consumes = {CONTENT_TYPE_FORMED})
    @ResponseBody
    public CommenReturnType register(@RequestParam(name="telphone") String telphone,
                                     @RequestParam(name="otpCode") String otpCode,
                                     @RequestParam(name="password") String password,
                                     @RequestParam(name="name") String name,
                                     @RequestParam(name="gender") Integer gender,
                                     @RequestParam(name="age") Integer age) throws BusinessException, UnsupportedEncodingException, NoSuchAlgorithmException {
        //驗(yàn)證手機(jī)號和otpcode相符合
        String inSessionOtpCode = (String)this.httpServletRequest.getSession().getAttribute(telphone);
        if(!StringUtils.equals(otpCode,inSessionOtpCode)){
            throw new BusinessException(EmBussinessError.PARMETER_VALIDATION_ERROR,"短信驗(yàn)證碼不符合");
        }
        //用戶注冊流程
        UserModel userModel = new UserModel();
        userModel.setName(name);
        //userModel.setGender(gender);
        userModel.setGender(new Byte(String.valueOf(gender.intValue())));

        userModel.setTelphone(telphone);
        userModel.setAge(age);
        userModel.setEncrptPassWord(this.EncodeByMd5(password));

        userService.register(userModel);

        return CommenReturnType.create(null);

    }

3.用戶登錄

    //用戶登錄接口
    @RequestMapping(value = "/login",method = {RequestMethod.POST}, consumes = {CONTENT_TYPE_FORMED})
    @ResponseBody
    public CommenReturnType login(@RequestParam(name="telphone") String telphone,
                                     @RequestParam(name="password") String password) throws BusinessException, UnsupportedEncodingException, NoSuchAlgorithmException {
        //入?yún)⑿ｒ?yàn)
        if(StringUtils.isEmpty(telphone)||
                StringUtils.isEmpty(password)){
            throw new BusinessException(EmBussinessError.PARMETER_VALIDATION_ERROR);
        }

        //用戶登錄服務(wù)，用來校驗(yàn)用戶登錄是否合法
        UserModel userModel = userService.validateLogin(telphone,this.EncodeByMd5(password));

        //將登錄憑證加入到用戶登錄成功的session內(nèi)
        this.httpServletRequest.getSession().setAttribute("IS_LOGIN",true);
        this.httpServletRequest.getSession().setAttribute("LOGIN_USER",userModel);

        return CommenReturnType.create(null);

    }

4.優(yōu)化校驗(yàn)

(1) 檢驗(yàn)結(jié)果

import org.apache.commons.lang3.StringUtils;

import java.util.HashMap;
import java.util.Map;

public class ValidationResult {
    //校驗(yàn)結(jié)果是否有錯(cuò)
    private boolean hasErrors = false;
    private Map<String,String> errMsgMap = new HashMap<>();

    public boolean isHasErrors() {
        return hasErrors;
    }

    public void setHasErrors(boolean hasErrors) {
        this.hasErrors = hasErrors;
    }

    public Map<String, String> getErrMsgMap() {
        return errMsgMap;
    }

    public void setErrMsgMap(Map<String, String> errMsgMap) {
        this.errMsgMap = errMsgMap;
    }
    //實(shí)現(xiàn)通用的通過格式化字符串信息獲取錯(cuò)誤結(jié)果的msg的方法

    public  String getErrMsg(){
        return StringUtils.join(errMsgMap.values().toArray(),",");

    }
}

(2)校驗(yàn)器

import org.springframework.beans.factory.InitializingBean;
import org.springframework.stereotype.Component;

import javax.validation.ConstraintViolation;
import javax.validation.Validation;
import javax.validation.Validator;
import java.util.Set;

@Component
public class ValidatorImpl implements InitializingBean {

    private Validator validator;

    //實(shí)現(xiàn)校驗(yàn)方法并返回結(jié)果
    public ValidationResult validate(Object bean){
        final ValidationResult result = new ValidationResult();
        Set<ConstraintViolation<Object>> constraintViolationSet = validator.validate(bean);
        if(constraintViolationSet.size()>0){
            //有錯(cuò)誤
            result.setHasErrors(true);
            constraintViolationSet.forEach(constraintViolation->{
                String errMsg = constraintViolation.getMessage();
                String propertyName = constraintViolation.getPropertyPath().toString();
                result.getErrMsgMap().put(propertyName,errMsg);
            });
        }
        return result;


    }

    @Override
    public void afterPropertiesSet() throws Exception {
        //將hibernate validator 通過工廠的初始化方式使其實(shí)例化
        this.validator = (Validator) Validation.buildDefaultValidatorFactory().getValidator();
    }
}
