小编给大家分享一下Java怎么通过注解实现接口输出时数据脱敏,相信大部分人都还不怎么了解,因此分享这篇文章给大家参考一下,希望大家阅读完这篇文章后大有收获,下面让我们一起去了解一下吧!
在后台管理中,对于手机号,身份证,姓名这些数据不允许所有人都能看,这时候我们要对相对数据进行脱敏.
通过对相关接口函数进行声明,以及配置需要脱敏的参数类型SecretTypeEnum,默认脱敏手机号
/** * 脱敏声明 */ @Documented @Target(ElementType.METHOD) @Retention(RetentionPolicy.RUNTIME) public @interface SecretManage { SecretTypeEnum[] value() default {SecretTypeEnum.MOBILE}; }
身份证,用户姓名三个字段进行脱敏, 字段名称必须符合枚举的desc值
package com.test.base.enums; import com.fasterxml.jackson.annotation.JsonValue; /** * @author fyf * @date 2021/2/26 */ public enum SecretTypeEnum implements BaseEnum { MOBILE(0, "mobile"), NAME(1, "name"), ID(2, "identity") ; @JsonValue private int code; private String desc; public String getDesc() { return desc; } SecretTypeEnum(int code, String desc) { this.code = code; this.desc = desc; } @Override public int code() { return code; } public static SecretTypeEnum checkParam(String paramName) { SecretTypeEnum[] values = values(); for (int i = 0; i < values.length; i++) { if (paramName.equals(values[i].getDesc())) { return values[i]; } } return null; } }
/** * 对字段进行脱敏管理 * @author: fyf * @date: 2021/02/23 */ @Order(1) @Aspect @Component public class SecretManageAspect { @Pointcut("@annotation(com.test.base.annotations.SecretManage)") public void pointCut() { } @Around("pointCut() && @annotation(secretManage)") public Object secretManageAround(ProceedingJoinPoint joinPoint, SecretManage secretManage) throws Throwable { Class returnType = ((MethodSignature) joinPoint.getSignature()).getReturnType(); Object invokeResult = joinPoint.proceed(); if (returnType.isInstance(invokeResult)) { returnType.cast(invokeResult); } Field[] fields = returnType.getDeclaredFields(); List<SecretTypeEnum> annotationSecretTypeEnums = Arrays.asList(secretManage.value()); for (Field field : fields) { String fieldName = field.getName(); Class<?> paramType = field.getType(); System.out.println("字段名称:" + fieldName); SecretTypeEnum secretTypeEnum = SecretTypeEnum.checkParam(fieldName); long count = annotationSecretTypeEnums.stream().filter(item -> item.equals(secretTypeEnum)).count(); if (secretTypeEnum != null && count > 0) { fieldName = fieldName.substring(0, 1).toUpperCase() + fieldName.substring(1); // 获取到setter方法 Method setMethod = returnType.getMethod("set" + fieldName, new Class[]{paramType}); // 获取到getter方法 Method getMethod = returnType.getMethod("get" + fieldName); // 执行getter方法 Object value = getMethod.invoke(invokeResult); this.invokeSetter(setMethod, invokeResult, secretTypeEnum, value); } } return invokeResult; } /** * 封装执行setter函数 */ private void invokeSetter(Method setterMethod, Object invokeResult, SecretTypeEnum secretTypeEnum, Object value) throws InvocationTargetException, IllegalAccessException { switch (secretTypeEnum) { case NAME: setterMethod.invoke(invokeResult, SecretUtil.nameSecret(value.toString())); break; case MOBILE: setterMethod.invoke(invokeResult, SecretUtil.mobileSecret(value.toString())); break; case ID: setterMethod.invoke(invokeResult, SecretUtil.idNoSecret(value.toString())); break; } } }
上面我们就是实现了脱敏的功能,现在我们可以mock接口看看结果了,
/** * curl localhost:9999/user/test-secret */ @GetMapping("/test-secret") // @SecretManage(value = {SecretTypeEnum.NAME, SecretTypeEnum.MOBILE}) @SecretManage public User getSecretUser() { User user = new User(); user.setId(1); user.setMobile("13715166409"); user.setName("张志新"); user.setIdentity("370283790911703"); return user; }
下面是测试结果
有这样一个场景,系统中可以出现敏感的数据,在打印日志的时候,我们并不希望打印出现,这样,我们使用自己定义注解,来解决这个问题。

使用了google 的API,可以使用maven在添加,配置如下:
<!-- gson --> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> </dependency>
说明:在需要脱敏的字段上使用定义好的注解,在具体的使用时用SensitiveInfoUtils.getJson(a1),如果不需要脱敏的输出,尽量不要打印JSON,使用对象的toString()输出。效率更高。
