Omitting one Setter/Getter in Lombok

You can pass an access level to the @Getter and @Setter annotations. This is useful to make getters or setters protected or private. It can also be used to override the default.

With @Data, you have public access to the accessors by default. You can now use the special access level NONE to completely omit the accessor, like this:

@Getter(AccessLevel.NONE)
@Setter(AccessLevel.NONE)
private int mySecret;

Use the below code for omit/excludes from creating setter and getter. value key should use inside @Getter and @Setter.

@Getter(value = AccessLevel.NONE)
@Setter(value = AccessLevel.NONE)
private String mySecret;

According to @Data description you can use:

All generated getters and setters will be public. To override the access level, annotate the field or class with an explicit @Setter and/or @Getter annotation. You can also use this annotation (by combining it with AccessLevel.NONE) to suppress generating a getter and/or setter altogether.
