【Springboot之切面编程】自定义注解实现入参指定枚举值校验

通过自定义枚举注解
@EnumValidator(value = SexEnums.class)，
private Integer sex;
就可以校验入参值必须在指定枚举类中

自定义枚举校验注解

1.定义自定义枚举@EnumValidator

package com.enums.validate.base;

import javax.validation.Constraint;
import javax.validation.Payload;
import java.lang.annotation.*;

/**
 * 枚举值校验注解
 *
 * @author: zetting
 * @date:2018/12/18
 */
@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.FIELD, ElementType.METHOD})
@Constraint(validatedBy = EnumValidatorClass.class)
public @interface EnumValidator {
    Class value();

    String message() default "入参值不在正确枚举中";

    Class[] groups() default {};

    Class[] payload() default {};
}

2.定义实现枚举值校验处理类EnumValidatorClass

 
package com.enums.validate.base;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.validation.ConstraintValidator;
import javax.validation.ConstraintValidatorContext;
import java.lang.annotation.Annotation;
import java.lang.reflect.Method;
import java.util.ArrayList;
import java.util.List;
import java.util.Objects;

/**
 * 枚举值校验注解实现
 *
 * @author: zetting
 * @date:2018/12/18
 */
public class EnumValidatorClass implements ConstraintValidator, Annotation {
    private Logger log = LoggerFactory.getLogger(this.getClass());
    private List
