[BUG] getter and setter method consistent with the rules

[liusha001]

I am terribly sorry for my poor English.
Describe
The first word is a lowercase letter, the second uppercase, getter/setter method not consistent with the rules

To Reproduce

@Data
public class User {
    private String uName;
}

        User user = new User();
        // should be getuName()
        user.setUName("Jim");

getter/setter method should be getuName()/setuName()
