一、版本信息及maven依赖
hibernate-validator 7.x版本有问题，暂时以6.2.1.Final为例，6.2.1.Final版本解决了Log4j版本的漏洞
1.8 UTF-8 UTF-8 5.7.16 6.2.1.Final
记得引入：spring-boot-starter-validation
org.springframework.boot spring-boot-starter-validation org.hibernate.validator hibernate-validator cn.hutool hutool-all ${hutool.version}
二、定义实体bean
import javax.validation.constraints.Email;
import javax.validation.constraints.Max;
import javax.validation.constraints.Min;
import javax.validation.constraints.NotBlank;
import org.hibernate.validator.constraints.Length;
public class User {
private Integer id;
@Min(18)
@Max(200)
private Integer age;
@NotBlank(message = "姓名不能为空")
@Length(min = 2, max = 6, message = "长度必须在{min}和{max}个字符之间")
private String name;
@NotBlank(message = "电子邮箱不能为空")
@Email(message = "电子邮箱格式不正确")
private String email;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
@Override
public String toString() {
return "User [id=" + id + ", age=" + age + ", name=" + name + ", email=" + email + "]";
}
}
三、测试Controller
需要在类上面加上注解：@Validated
import javax.validation.Valid;
import javax.validation.constraints.NotNull;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@Validated
public class UserController {
@RequestMapping("/get")
public User get(@NotNull(message = "id不能为空") Integer id,
@NotNull(message = "姓名不能为空") String name) {
User user = new User();
user.setName("lisi");
user.setId(id);
return user;
}
@RequestMapping("/save")
public User get(@Valid User user) {
return user;
}
}
四、hibernate-validator全局异常处理
import java.util.List;
import java.util.Set;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.validation.ConstraintViolation;
import javax.validation.ConstraintViolationException;
import org.springframework.http.HttpStatus;
import org.springframework.validation.BindException;
import org.springframework.validation.FieldError;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;
@ControllerAdvice
public class GlobalException {
public static final String DELIM = "，";
@ExceptionHandler(Exception.class)
@ResponseBody
public String exceptionHandler(HttpServletRequest request, HttpServletResponse response,
Exception e) {
if(e instanceof ConstraintViolationException) {
//@RequestParam上参数validate失败后抛出的异常
ConstraintViolationException cve = (ConstraintViolationException) e;
Set> violations = cve.getConstraintViolations();
StringBuffer sb = new StringBuffer("");
for (ConstraintViolation constraintViolation : violations) {
sb.append(constraintViolation.getMessage()).append(DELIM);
}
if(sb.indexOf(DELIM) > -1) {
sb.deleteCharAt(sb.length() - 1);
}
System.out.println("ConstraintViolationException sb="+sb);
response.setStatus(HttpStatus.BAD_REQUEST.value());
return sb.toString();
}else if(e instanceof BindException) {
//@RequestParam上实体对象validate失败后抛出的异常
BindException be = (BindException) e;
System.out.println("be.getMessage()="+be.getMessage());
List fieldErrors = be.getBindingResult().getFieldErrors();
StringBuffer sb = new StringBuffer("");
for (FieldError fieldError : fieldErrors) {
sb.append(fieldError.getDefaultMessage()).append(DELIM);
//System.out.println("fieldError.getDefaultMessage() =" + fieldError.getDefaultMessage());
}
if(sb.indexOf(DELIM) > -1) {
sb.deleteCharAt(sb.length() - 1);
}
System.out.println("BindException sb="+sb);
response.setStatus(HttpStatus.BAD_REQUEST.value());
return sb.toString();
}else if(e instanceof MethodArgumentNotValidException) {
//@RequestBody上validate失败后抛出的异常
MethodArgumentNotValidException mave = (MethodArgumentNotValidException) e;
System.out.println("mave.getMessage() = " + mave.getMessage());
List fieldErrors = mave.getBindingResult().getFieldErrors();
StringBuffer sb = new StringBuffer("");
for (FieldError fieldError : fieldErrors) {
sb.append(fieldError.getDefaultMessage()).append(DELIM);
//System.out.println("fieldError.getDefaultMessage() =" + fieldError.getDefaultMessage());
}
if(sb.indexOf(DELIM) > -1) {
sb.deleteCharAt(sb.length() - 1);
}
System.out.println("MethodArgumentNotValidException sb="+sb);
response.setStatus(HttpStatus.BAD_REQUEST.value());
return sb.toString();
}
return "系统异常";
}
}
五、hibernate-validator快速校验
hibernate-validator默认会全部校验后再返回所有错误结果，为了让hibernate-validator检查到第一个错误马上返回结果，需要配置快速校验
import javax.validation.Validation;
import javax.validation.Validator;
import javax.validation.ValidatorFactory;
import org.hibernate.validator.HibernateValidator;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.validation.beanvalidation.MethodValidationPostProcessor;
@Configuration
public class ValidatorConfiguration {
/**
* 快速返回校验器
* @return
*/
@Bean
@ConditionalOnMissingBean(value = Validator.class)
public Validator validator() {
//hibernate-validator 6.x没问题，7.x有问题
ValidatorFactory validatorFactory = Validation.byProvider(HibernateValidator.class)
.configure()
.failFast(true)
//.addProperty("hibernate.validator.fail_fast", "true")
.buildValidatorFactory();
return validatorFactory.getValidator();
}
/**
* 设置快速校验，返回方法校验处理器
* @return
*/
@Bean
@ConditionalOnMissingBean(value = MethodValidationPostProcessor.class)
public MethodValidationPostProcessor methodValidationPostProcessor() {
MethodValidationPostProcessor postProcessor = new MethodValidationPostProcessor();
postProcessor.setValidator(validator());
return postProcessor;
}
}
