All together now: A shortcut for
@ToString,@EqualsAndHashCode,@Getteron all fields,@Setteron all non-final fields, and@RequiredArgsConstructor!Overview
@Datais a convenient shortcut annotation that bundles the features of@ToString,@EqualsAndHashCode,@Getter/@Setterand@RequiredArgsConstructortogether: In other words,@Datagenerates all the boilerplate that is normally associated with simple POJOs (Plain Old Java Objects) and beans: getters for all fields, setters for all non-final fields, and appropriatetoString,equalsandhashCodeimplementations that involve the fields of the class, and a constructor that initializes all final fields, as well as all non-final fields with no initializer that have been marked with@NonNull, in order to ensure the field is never null.
@Datais like having implicit@Getter,@Setter,@ToString,@EqualsAndHashCodeand@RequiredArgsConstructorannotations on the class (except that no constructor will be generated if any explicitly written constructors already exist). However, the parameters of these annotations (such ascallSuper,includeFieldNamesandexclude) cannot be set with@Data. If you need to set non-default values for any of these parameters, just add those annotations explicitly;@Datais smart enough to defer to those annotations.All generated getters and setters will be
public. To override the access level, annotate the field or class with an explicit@Setterand/or@Getterannotation. You can also use this annotation (by combining it withAccessLevel.NONE) to suppress generating a getter and/or setter altogether.All fields marked as
transientwill not be considered forhashCodeandequals. All static fields will be skipped entirely (not considered for any of the generated methods, and no setter/getter will be made for them).If the class already contains a method with the same name and parameter count as any method that would normally be generated, that method is not generated, and no warning or error is emitted. For example, if you already have a method with signature
equals(AnyType param), noequalsmethod will be generated, even though technically it might be an entirely different method due to having different parameter types. The same rule applies to the constructor (any explicit constructor will prevent@Datafrom generating one), as well astoString,equals, and all getters and setters. You can mark any constructor or method with@lombok.experimental.Tolerateto hide them from lombok.
@Datacan handle generics parameters for fields just fine. In order to reduce the boilerplate when constructing objects for classes with generics, you can use thestaticConstructorparameter to generate a private constructor, as well as a static method that returns a new instance. This way, javac will infer the variable name. Thus, by declaring like so:@Data(staticConstructor="of") class Foo<T> { private T x;}you can create new instances ofFooby writing:Foo.of(5);instead of having to write:new Foo<Integer>(5);.@Data

}+++++++++++++++++++++++@SneakyThrows
To boldly throw checked exceptions where no one has thrown them before!
Overview
@SneakyThrowscan be used to sneakily throw checked exceptions without actually declaring this in your method'sthrowsclause. This somewhat contentious ability should be used carefully, of course. The code generated by lombok will not ignore, wrap, replace, or otherwise modify the thrown checked exception; it simply fakes out the compiler. On the JVM (class file) level, all exceptions, checked or not, can be thrown regardless of thethrowsclause of your methods, which is why this works.Common use cases for when you want to opt out of the checked exception mechanism center around 2 situations:
- A needlessly strict interface, such as
Runnable- whatever exception propagates out of yourrun()method, checked or not, it will be passed to theThread's unhandled exception handler. Catching a checked exception and wrapping it in some sort ofRuntimeExceptionis only obscuring the real cause of the issue.- An 'impossible' exception. For example,
new String(someByteArray, "UTF-8");declares that it can throw anUnsupportedEncodingExceptionbut according to the JVM specification, UTF-8 must always be available. AnUnsupportedEncodingExceptionhere is about as likely as aClassNotFoundErrorwhen you use a String object, and you don't catch those either!Being constrained by needlessly strict interfaces is particularly common when using lambda syntax (
arg -> action); however, lambdas cannot be annotated, which means it is not so easy to use@SneakyThrowsin combination with lambdas.Be aware that it is impossible to catch sneakily thrown checked types directly, as javac will not let you write a catch block for an exception type that no method call in the try body declares as thrown. This problem is not relevant in either of the use cases listed above, so let this serve as a warning that you should not use the
@SneakyThrowsmechanism without some deliberation!You can pass any number of exceptions to the
@SneakyThrowsannotation. If you pass no exceptions, you may throw any exception sneakily.
With Lombok
import lombok.SneakyThrows;
public class SneakyThrowsExample implements Runnable {
@SneakyThrows(UnsupportedEncodingException.class)
public String utf8ToString(byte[] bytes) {
return new String(bytes, "UTF-8");
}
@SneakyThrows
public void run() {
throw new Throwable();
}
}
Vanilla Java
import lombok.Lombok;
public class SneakyThrowsExample implements Runnable {
public String utf8ToString(byte[] bytes) {
try {
return new String(bytes, "UTF-8");
} catch (UnsupportedEncodingException e) {
throw Lombok.sneakyThrow(e);
}
}
public void run() {
try {
throw new Throwable();
} catch (Throwable t) {
throw Lombok.sneakyThrow(t);
}
