lombok build getters/setters not by standard Java Beans specification

code

standard java beans getter/setter

public class A {
private String vNum;
public void setvNum(String vNum) {
    this.vNum=vNum;
}
public String getvNum() {
    return vNum;
}
}

lombok getter/setter (decoder result)

public class A {
private String vNum;
public void setVNum(String vNum) {
    this.vNum=vNum;
}
public String getVNum() {
    return vNum;
}
}

resolve

you can use Introspector.decapitalize(name) get property

Seems to be another dupe in the pile: #757, #1593, #1496, #1453, #1454.

There are conflicting implementations, even in java.beans.

• java.beans.NameGenerator.capitalize

    public static String capitalize(String name) {
        if (name == null || name.length() == 0) {
            return name;
        }
        return name.substring(0, 1).toUpperCase(ENGLISH) + name.substring(1);
    }

• java.beans.PropertyDescriptor (constructor uses NameGenerator)
• Introspector.decapitalize

    public static String decapitalize(String name) {
        if (name == null || name.length() == 0) {
            return name;
        }
        if (name.length() > 1 && Character.isUpperCase(name.charAt(1)) &&
                        Character.isUpperCase(name.charAt(0))){
            return name;
        }
        char chars[] = name.toCharArray();
        chars[0] = Character.toLowerCase(chars[0]);
        return new String(chars);
    }

If we would have started lombok right now we might have made a different choice.

@rspilker
most open sources frameworks use Introspector.decapitalize(name) method build java beans
example: spring, dozer, jackson etc...
