如何使用?

sensitive-spring-boot-starter也支持SpringBoot3

3.0.0及以上版本的sensitive-spring-boot-starter只针对使用SpringBoot3用户,SpringBoot2用户请使用低于3.0.0版本的sensitive-spring-boot-starter,两者功能不受影响,均会同步更新!

1.导入依赖

依赖已发布至Maven中央仓库,可直接引入依赖。

  • Maven:

    <dependency>
      <groupId>com.lzhpo</groupId>
      <artifactId>sensitive-spring-boot-starter</artifactId>
      <version>${latest-version}</version>
    </dependency>
  • Gradle:

    implementation 'com.lzhpo:sensitive-spring-boot-starter:${latest-version}'

2.实体类字段上使用@Sensitive注解配置脱敏规则

@Sensitive注解说明:

  • strategy:脱敏策略,支持12种脱敏策略。
  • replacer:脱敏策略的替换符,默认脱敏替换符为星号*,可以配置为任意字符。 比如:配置为#
    @Sensitive(strategy = SensitiveStrategy.CHINESE_NAME, replacer = '#')
    private String name;

2.1.支持的脱敏策略

以下数据均为随意构造的测试数据,如有相同,纯属巧合。

2.1.1 中文姓名

只显示第一个汉字,其他隐藏为2个星号。

@Sensitive(strategy = SensitiveStrategy.CHINESE_NAME)
private String name;

比如:刘子豪脱敏之后为刘**

2.1.2 身份证号

保留前1位和后2位。

@Sensitive(strategy = SensitiveStrategy.ID_CARD)
private String idCard;

比如:530321199204074611脱敏之后为5***************11

2.1.3 固定电话

保留前4位和后2位。

@Sensitive(strategy = SensitiveStrategy.FIXED_PHONE)
private String fixedPhone;

比如:01086551122脱敏之后为0108*****22

2.1.4 手机号码

保留前3位和后4位。

@Sensitive(strategy = SensitiveStrategy.MOBILE_PHONE)
private String mobilePhone;

比如:13248765917脱敏之后为132****5917

2.1.5 地址

只显示到地区,不显示详细地址,地址长度减去8即为前缀保留的长度,后缀均用星号代替。

@Sensitive(strategy = SensitiveStrategy.ADDRESS)
private String address;

比如:广州市天河区幸福小区102号脱敏之后为广州市天河区********

2.1.6 电子邮箱

邮箱前缀仅显示第一个字母,前缀其他隐藏,用星号代替,@及后面的地址显示。

@Sensitive(strategy = SensitiveStrategy.EMAIL)
private String email;

比如:example@gmail.com脱敏之后为e******@gmail.com

2.1.7 密码

全部字符都用星号*代替。

@Sensitive(strategy = SensitiveStrategy.PASSWORD)
private String password;

比如:123456脱敏之后为******

2.1.8 车牌号

车牌中间用星号*代替。

@Sensitive(strategy = SensitiveStrategy.CAR_LICENSE)
private String carLicense;

比如:粤A66666脱敏之后为粤A6***6

2.1.9 银行卡号

保留前4位和后4位,中间的使用星号*代替,且中间的从第1位起,每隔4位添加一个空格用来美化。

@Sensitive(strategy = SensitiveStrategy.BANK_CARD)
private String bankCard;

例如:9988002866797031脱敏之后为9988 **** **** 7031

2.2.1 自定义脱敏策略

当前支持三种风格的自定义脱敏策略:

  1. 保留前后缀脱敏策略。
  2. 敏感字符脱敏策略。
  3. Handler脱敏策略。
2.2.1.1 保留前后缀脱敏策略

使用@Sensitive(strategy = SensitiveStrategy.CUSTOMIZE_KEEP_LENGTH)配合@SensitiveKeepLength一起使用。

@SensitiveFilterWords注解:

  • preKeep是字符串前置保留字符个数。
  • postKeep是字符串后置保留字符个数。

举个例子:name前后都只保留1个字符。

@Sensitive(strategy = SensitiveStrategy.CUSTOMIZE_KEEP_LENGTH)
@SensitiveKeepLength(preKeep = 1, postKeep = 1)
private String name;

如果name1234,脱敏之后就是1**4

2.2.1.2 敏感字符脱敏策略

使用@Sensitive(strategy = SensitiveStrategy.CUSTOMIZE_FILTER_WORDS)配合@SensitiveFilterWords一起使用。

@SensitiveFilterWords注解:定义敏感字符。

举个例子:脏话关键字脱敏。

@Sensitive(strategy = SensitiveStrategy.CUSTOMIZE_FILTER_WORDS)
@SensitiveFilterWords({"他妈的", "去你大爷", "卧槽", "草泥马", "废物"})
private String description;

如果description的值为卧槽,他妈的,我去你大爷的,草泥马,脱敏之后就是**,***,我****的,***

2.2.1.3 Handler脱敏策略

Handler脱敏策略完全由开发者进行处理,不受@Sensitive注解上的replacer脱敏替换符影响。

使用@Sensitive(strategy = SensitiveStrategy.CUSTOMIZE_HANDLER)配合@SensitiveHandler一起使用。

@SensitiveHandler注解:表示处理脱敏的Handler。

例如:将name字段都设置为@#@

@Sensitive(strategy = SensitiveStrategy.CUSTOMIZE_HANDLER)
@SensitiveHandler(FaceCustomizeSensitiveHandler.class)
private String name;
public class FaceCustomizeSensitiveHandler implements CustomizeSensitiveHandler {

  @Override
  public String customize(SensitiveWrapper sensitiveWrapper) {
    // 字段
    Field field = sensitiveWrapper.getField();
    // 字段归属的对象
    Class<?> objectClass = field.getDeclaringClass();
    // 字段上的注解
    Annotation[] annotations = field.getAnnotations();
    // 字段值
    String fieldValue = sensitiveWrapper.getFieldValue();
    // 注解信息
    Sensitive sensitive = sensitiveWrapper.getSensitive();
    return "@#@";
  }
}

可以看到,提供了含有@Sensitive注解的字段、字段值、字段归属的对象、注解的信息等等供开发者定制。

3.使用@IgnoreSensitive注解标注在controller上可忽略脱敏

如果实体类标注了@Sensitive脱敏,被多个接口共用的,接口A要脱敏,但是接口B不需要脱敏,就可以使用@IgnoreSensitive注解忽略脱敏,同时也支持忽略指定字段脱敏。

1.在Controller类上使用@IgnoreSensitive表示此类下所有接口都忽略脱敏

此controller下的所有接口都将忽略脱敏。

@RestController
@IgnoreSensitive
@RequestMapping("/ignore")
public class NoSensitiveController {

  @GetMapping("sample3")
  public ResponseEntity<SampleJavaBean> sample3() {
    return ResponseEntity.ok(SampleJavaBeanMock.sampleJavaBean());
  }

  @GetMapping("sample4")
  public ResponseEntity<SampleJavaBean> sample4() {
    return ResponseEntity.ok(SampleJavaBeanMock.sampleJavaBean());
  }
}

2.在Controller的方法中使用@IgnoreSensitive表示此接口忽略脱敏

@RestController
@RequestMapping("/")
public class SensitiveController {

  @GetMapping("sample1")
  public ResponseEntity<SampleJavaBean> sample1() {
    return ResponseEntity.ok(SampleJavaBeanMock.sampleJavaBean());
  }

  @IgnoreSensitive
  @GetMapping("ignore/sample2")
  public ResponseEntity<SampleJavaBean> sample2() {
    return ResponseEntity.ok(SampleJavaBeanMock.sampleJavaBean());
  }
}

sample2将忽略SampleJavaBean对象的字段脱敏,sample1不影响。

3.在Controller的类或方法中使用@IgnoreSensitive忽略指定字段脱敏

示例:忽略脱敏SampleJavaBean中的nameemail字段的脱敏。

@RestController
@RequestMapping("/")
public class SensitiveController {

  @IgnoreSensitive({"name", "email"})
  @GetMapping("ignore/sample")
  public ResponseEntity<SampleJavaBean> sample() {
    return ResponseEntity.ok(SampleJavaBeanMock.sampleJavaBean());
  }
}

注意事项

1.有关单独使用@Builder/@SuperBuilder注解、实体类多层嵌套问题

需要数据脱敏的实体类以及嵌套类都应提供对应成员变量的get方法,否则JSON组件无法获取到嵌套的成员变量进行脱敏!

  • 错误示范:嵌套对象单独使用一个@Builder/@SuperBuilder

  • 正确示范:如果需要使用到@Builder/@SuperBuilder,那么需要配合@Data@Getter一起使用。

    例如:

    @Data
    @Builder
    @NoArgsConstructor
    @AllArgsConstructor
    public class SensitiveEntity {
    
      @Sensitive(strategy = SensitiveStrategy.CHINESE_NAME)
      private String name;
    
      @Sensitive(strategy = SensitiveStrategy.ID_CARD)
      private String idCard;
    }

2.将默认的Jackson切换为FastJson(不推荐)

  1. 加入FastJson依赖(支持FastJson1和FastJson2):
    <dependency>
      <groupId>com.alibaba</groupId>
      <artifactId>fastjson</artifactId>
      <version>1.x.x/2.x.x</version>
    </dependency>
  2. FastJsonHttpMessageConverter声明为Bean即可,sensitive-spring-boot-starter会自动注入相关逻辑。
    @Bean
    public FastJsonHttpMessageConverter fastJsonHttpMessageConverter() {
      return new FastJsonHttpMessageConverter();
    }

3.关闭此数据脱敏功能

移除此maven依赖即可
