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:
<!-- 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。
