在《SpringBoot 2.0参数校验Hibernate Validator》基础上开发

1. 定义注解

package com.futao.springmvcdemo.annotation;

import com.futao.springmvcdemo.annotation.impl.IllegalValueCheckImpl;
import com.futao.springmvcdemo.model.entity.constvar.ErrorMessage;

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

/**
 * @author futao
 * Created on 2018/9/25.
 */
//关联解析类, 检验逻辑
@Constraint(validatedBy = IllegalValueCheckImpl.class)
@Target(value = {ElementType.PARAMETER})
@Retention(value = RetentionPolicy.RUNTIME)
@Documented
public @interface IllegalValueCheck {

    /**
     * 拦截的字符串
     *
     * @return
     */
    String forbidden() default "mmp";

    /**
     * 验证不通过时的错误提示信息
     *
     * @return
     */
    String message() default ErrorMessage.CONTAIN_ILLEGAL_PARAMETER;

    Class<?>[] groups() default {};

    /**
     * 变量名称 payload不可变
     * 否则会抛出异常`javax.validation.ConstraintDefinitionException: HV000074`
     *
     * @return
     */
    Class<? extends Payload>[] payload() default {};
}

2. 定义注解的实现逻辑类

package com.futao.springmvcdemo.annotation.impl;

import com.futao.springmvcdemo.annotation.IllegalValueCheck;
import org.apache.commons.lang3.ObjectUtils;

import javax.validation.ConstraintValidator;
import javax.validation.ConstraintValidatorContext;

/**
 * @author futao
 * Created on 2018/9/25.
 * 敏感词检测
 */
public class IllegalValueCheckImpl implements ConstraintValidator<IllegalValueCheck, String> {
    private String forbidden;

    /**
     * 初始化
     *
     * @param constraintAnnotation
     */
    @Override
    public void initialize(IllegalValueCheck constraintAnnotation) {
        //获取禁止的词汇
        this.forbidden = constraintAnnotation.forbidden();
    }

    /**
     * 检验逻辑
     *
     * @param value
     * @param context
     * @return
     */
    @Override
    public boolean isValid(String value, ConstraintValidatorContext context) {
        if (!ObjectUtils.allNotNull(value)) {
            return true;
        }
        if (value.contains(forbidden)) {
            return false;
        }
        return true;
    }
}

3. 测试
   3.1使用默认的敏感词

    /**
     * 添加评论
     *
     * @param content
     * @return
     */
    @PostMapping(path = "addReview")
    public SingleValueResult addReview(
            @RequestParam("content")
            @IllegalValueCheck
                    String content) {
        SingleValueResult result = new SingleValueResult(content);
        return result;
    }

使用默认的敏感词

3.2灵活使用敏感词

    /**
     * 添加评论
     *
     * @param content
     * @return
     */
    @PostMapping(path = "addReview")
    public SingleValueResult addReview(
            @RequestParam("content")
            @IllegalValueCheck(forbidden = "亚索")
                    String content) {
        SingleValueResult result = new SingleValueResult(content);
        return result;
    }

我亚索贼6

写代码的时候发现：如果Controller层返回的对象没有getter和setter会抛出org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation异常
