Hi,
I have found some usage of “String.equals("xxx")” in this project.

When using string.equals("a") ，it will get nullpointexception if string ==null.
The problem can be fixed by repalced with "a".equals(string) or Objects.equals(string,"a").

Detail websites and lines are listed below

There are too many cases of "fieldName.equals("xxxxx")" .

Best regards
