springboot验证注解

springboot 使用验证注解：需要引入spring-boot-starter-validation（使用Hibernate Validator 框架提供验证功能） 依赖进行参数校验

• 要验证的pojo 配置

package com.hjkj.facecomparison.person;

import javax.validation.constraints.NotBlank;

/**
 * 比对对象
 */
public class Person {
    @NotBlank(message = "待核验用户姓名不可为空")
    private String nameText;
    @NotBlank(message = "待核验用户身份证号不可为空")
    private String numberText;
    @NotBlank(message = "待核验用户现场照片不可为空")
    private String idPhoto;

    public String getNameText() {
        return nameText;
    }

    public void setNameText(String nameText) {
        this.nameText = nameText;
    }

    public String getNumberText() {
        return numberText;
    }

    public void setNumberText(String numberText) {
        this.numberText = numberText;
    }

    public String getIdPhoto() {
        return idPhoto;
    }

    public void setIdPhoto(String idPhoto) {
        this.idPhoto = idPhoto;
    }

    @Override
    public String toString() {
        return "Person{" +
                "nameText='" + nameText + '\'' +
                ", numberText='" + numberText + '\'' +
                ", idPhoto='" + idPhoto + '\'' +
                '}';
    }
}

• controller 配置

/**
 * 人脸比对处理类
 */
package com.hjkj.facecomparison.controller;


import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.hjkj.facecomparison.common.ResponseResult;
import com.hjkj.facecomparison.person.Person;
import com.hjkj.facecomparison.utils.HttpConnectionUtil;
import com.pinecone.utils.EncryptionUtils;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

import javax.validation.Valid;


/**
 * 人脸比对处理类
 */
@RestController
public class FaceComparisonController {

    @Value("${sm4Key}")
    private String sm4Key;
    @Value("${requestUrl}")
    private String requestUrl;
    @Value("${clientCode}")
    private String clientCode;

    /**
     * 获取比对结果
     *
     * @param person {"nameText":"",numberText:"",idPhoto:""}
     * @return json
     */
    @PostMapping(value = "/comparisonResult")
    @ResponseBody
    public ResponseResult faceComparisonResult(@RequestBody @Valid Person person) throws Exception {
        JSONObject source = new JSONObject();
        source.put("clientCode", clientCode);
        source.put("encryptString", EncryptionUtils.encryptSM4(sm4Key, JSON.toJSONString(person)));
        // return HttpConnectionUtil.doPost(requestUrl, source.toString());
        JSONObject jsonObject = JSON.parseObject(HttpConnectionUtil.doPost(requestUrl, source.toString()));
        String result = jsonObject.getString("result");
        if (result != null && result.equals("-1")) {
            return ResponseResult.error(result, jsonObject.getString("errCode"),
                    jsonObject.getString("resultDetail"), "比对失败");
        }
        return ResponseResult.success(jsonObject.getString("result"), jsonObject.getString("similarity"), jsonObject.getString("resultDetail"));

    }

}

• 验证异常处理

package com.hjkj.facecomparison.exception
import com.hjkj.facecomparison.common.ResponseResult;
import com.hjkj.facecomparison.common.ResponseStatuses;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.validation.BindingResult;
import org.springframework.validation.FieldError;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.*;
/**
 * 全局异常处理类
 *
 * @author Jack
 */
@ControllerAdvice
public class GlobalExceptionHandler {

    private static final Logger log = LoggerFactory.getLogger(GlobalExceptionHandler.class);
    /**
     * 校验对象参数异常
     * @param ex
     */
    @ExceptionHandler(MethodArgumentNotValidException.class)
    @ResponseBody
    public ResponseResult validExceptionHandler(MethodArgumentNotValidException ex) {
        BindingResult bindingResult = ex.getBindingResult();
        StringBuffer stringBuffer = new StringBuffer();
        if (bindingResult.hasErrors()) {
            for (FieldError fieldError : bindingResult.getFieldErrors()) {
                //该格式仅仅作为response展示和log作用，前端应自己做校验
                stringBuffer.append(fieldError.getDefaultMessage() + " ");
            }
        }
        log.error(stringBuffer.toString());
        return ResponseResult.error(ResponseStatuses.ERROR_PARAMS_NOT_IS_BLANK.getCode(),stringBuffer.toString());
    }

• 高复应响应对象

package com.hjkj.facecomparison.common;


public class ResponseResult {
    private String errCode;
    private String result;
    private String resultDetail;
    private String similarity;


    public ResponseResult(String result, String resultDetail, String similarity) {
        this.result = result;
        this.resultDetail = resultDetail;
        this.similarity = similarity;
    }

    public ResponseResult(String errCode, String result, String resultDetail, String similarity) {
        this.errCode = errCode;
        this.result = result;
        this.resultDetail = resultDetail;
        this.similarity = similarity;
    }
    public ResponseResult(String result, String resultDetail) {
        this.result = result;
        this.resultDetail = resultDetail;
    }

    public static ResponseResult success(String result, String similarity, String resultDetail) {
        return  new ResponseResult(result, similarity, resultDetail);
    }

    public static ResponseResult error(String result, String errCode, String resultDetail, String similarity){
        return new ResponseResult( errCode,result, resultDetail,similarity);
    }

    public static ResponseResult errorException(String result, String resultDetail){
        return new ResponseResult( result, resultDetail);
    }

    public String getSimilarity() {
        return similarity;
    }

    public void setSimilarity(String similarity) {
        this.similarity = similarity;
    }

    public String getErrCode() {
        return errCode;
    }

    public void setErrCode(String errCode) {
        this.errCode = errCode;
    }

    public String getResult() {
        return result;
    }

    public void setResult(String result) {
        this.result = result;
    }

    public String getResultDetail() {
        return resultDetail;
    }

    public void setResultDetail(String resultDetail) {
        this.resultDetail = resultDetail;
    }
}
