How to generate the Builder java class for your PO

问题:

I have this pojo file that consists over 50 attributes. Creating a manual builder class can be error prone activity.

Is there a easy way to generate the builder class? for e.g. If you required to generate getter setters you would normally use eclipse Source > Generate Getters and Setters Is there a painless procedure to perform this?

Really appreciate any help..

回答1:

Use Lombok.

You can annotate your class, for example:

@Data //generate getters and setters
@EqualsAndHashCode(callSuper=true) //self descriptive
@NoArgsConstructor //self descriptive
@AllArgsConstructor //self descriptive

Remark: it works only with Eclipse for now.

I have just used Practical macros, within a few minutes of install from the market place, I could generate *constructors*, getters / setters, toString, hashcode and equals (basically chaining the standard eclipse commands) in a single command. Just what I was looking for and saved me loads of time. I can also see a lot more uses for it, well done to Earnst (the creator).
