El llenguatge Java no té Properties com el .Net, ni té paràmetres opcionals. En Java ofereix alternatives menys netes. Quantes vegades cal escriure el codi del getter, setter de la propietat, definir el Logger a partir del nom de la classe, picar el codi de l’equals o el hashCode(). Tot això es pot simplificar si es fa servir https://projectlombok.org/features/all
val
Finally! Hassle-free final local variables.
var
Mutably! Hassle-free local variables.
@NonNull
or: How I learned to stop worrying and love the NullPointerException.
@Cleanup
Automatic resource management: Call your close() methods safely with no hassle.
@Getter/@Setter
Never write public int getFoo() {return foo;} again.
@ToString
No need to start a debugger to see your fields: Just let lombok generate a toString for
you!
@EqualsAndHashCode
Equality made easy: Generates hashCode and equals implementations from the
fields of your object..
@NoArgsConstructor, @RequiredArgsConstructor and @AllArgsConstructor
Constructors made to order: Generates constructors that take no arguments, one argument per final / non-nullfield, or one argument for every field.
@Data
All together now: A shortcut for @ToString, @EqualsAndHashCode,
@Getter on all fields, and @Setter on all non-final fields, and
@RequiredArgsConstructor!
@Value
Immutable classes made very easy.
@Builder
… and Bob’s your uncle: No-hassle fancy-pants APIs for object creation!
@SneakyThrows
To boldly throw checked exceptions where no one has thrown them before!
@Synchronized
synchronized done right: Don’t expose your locks.
@Getter(lazy=true)
Laziness is a virtue!
@Log
Captain’s Log, stardate 24435.7: “What was that line again?”
