Overview
Lombok is a Java annotation library that helps reduce boilerplate code.
Annotations
@Slf4j
The annotation generates a SLF4J Logger in the class. It has the same effect as if you were to explicitly add the following lines within the class:
private static final org.slf4j.Logger log = org.slf4j.LoggerFactory.getLogger(MyClass.class);
@Data
Generates:
- Getters for all fields
- A useful toString() method
- hashCode() and equals() implementations that check all non-transient fields
- Setters for all non-final fields
- A constructor
Equivalent to @Getter @Setter, @RequiredArgsConstructor @ToString @EqualsAndHashCode
