JAVA注解的字段脱敏处理

电玩女神 2024-02-18 20:10 9阅读 0赞

java 中对自定义注解的说明请参见：

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。

定义需要脱敏的字段规则。

使用了google 的API, 可以使用maven在添加,配置如下：

**\[html\]** [view plain][] [copy][view plain]

1.  
2.  <dependency>
3.  <groupId>com.google.code.gson</groupId>
4.  <artifactId>gson</artifactId>
5.  </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。
