日志过滤与手机号验证-优快云博客

本文介绍了一种使用自定义注解@NoHealth排除特定接口日志输出的方法，以及一个用于验证手机号格式的自定义注解@MobilePhone，确保输入符合特定规则。

案例1：

1.demand，排除某个接口的日志输出，用自定义注解@NoHealth，只要有该注解的方法，切面日志忽略该方法。

2.code

NoHealth interface:

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

/**
 * @author li
 */
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface NoHealth {
}

Aspect class:

排除有该注解的方法!@annotation(NoHealth)

@Component
@Aspect
public class ControllerAspect extends AbstractAspect {

    private static CxLogger logger = CxLogManager.getLogger(ControllerAspect.class).defaultTag("type", "ControllerAspect");

    private static final String INBOUND = "INBOUND";

    @Pointcut("execution(* com.xxx.xxx.xxx.controller..*(..))&&!@annotation(NoHealth)")
    private void controllerPointCut() {
    }

//*******other

}

controller

/**
 * @author li
 */
@RestController
public class HealthCheckController {

    private static CxLogger logger = CxLogManager.getLogger(AccessController.class).tag("type", "controller");

    @GetMapping("/_health")
    @NoHealth
    public String check() {
        
        return "OK";
    }

    
}

案例2：

需求：一个自定义注解，接收参数只能是‘-+数字’最长20位的属性注解@MobilePhone

定义类：

package com.cathaypacific.ird2.iam.validator;


import org.apache.commons.lang.StringUtils;

import javax.validation.Constraint;
import javax.validation.ConstraintValidator;
import javax.validation.ConstraintValidatorContext;
import javax.validation.Payload;
import java.lang.annotation.*;
import java.util.regex.Pattern;
/**
 * Desc:
 *
 * @author daxing.li
 * @create 2019-06-26 14:50
 */

@Target({ElementType.FIELD})
@Retention(RetentionPolicy.RUNTIME)
@Constraint(validatedBy = {MobilePhone.MobilePhoneConstraintValidator.class})
@Documented
public @interface MobilePhone {

    String message() default "Invalid MobilePhone Number";

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

    Class<? extends Payload>[] payload() default {};

    public static class MobilePhoneConstraintValidator implements ConstraintValidator<MobilePhone, String> {

        public MobilePhoneConstraintValidator(){

        }

        @Override
        public void initialize(MobilePhone constraintAnnotation){

        }

        @Override
        public boolean isValid(String s, ConstraintValidatorContext constraintValidatorContext) {
            if (StringUtils.isEmpty(s)) {
                return true;
            } else {
                return Pattern.matches("^[-+0-9]{0,20}$", s);
            }
        }
    }

}

2.应用：

xxxRequest.class

@Getter
@Setter
public void xxxRequest{

  @MobilePhone(message = "MobilePhone only for 'numbers and - +',and length cannot exceed 20 characters")
    @JsonProperty("mobile_phone")
    private String mobilePhone;
}
