In the past, when coding the object model, we need to write a lot of get/set and different constructors. Lombok provides us with a very good plug-in form.
In most projects, it's enough to use the following set of annotations. If you need to see more options, please refer to: Portal

• @Getter
• @Setter
• @ToString
• @RequiredArgsConstructor
  Constructor to generate final field

        /**
         * java class
         */
        @RequiredArgsConstructor
        class UserVO {
            private final Integer id;
            private final String name;
            private int age;
        }
        
        /**
         * Compiled code
         */
        class UserVO {
            private final Integer id;
            private final String name;
            private int age;
        
            public UserVO(Integer id, String name) {
                this.id = id;
                this.name = name;
            }
      }
  

• @Data
  Combinatorial annotation

    /**
     * @see Getter
     * @see Setter
     * @see RequiredArgsConstructor
     * @see ToString
     * @see EqualsAndHashCode
     * @see lombok.Value
     */
    @Target(ElementType.TYPE)
    @Retention(RetentionPolicy.SOURCE)
    public @interface Data {
        /**
         * ...
         */
        String staticConstructor() default "";
    }

• @Builder
  Change the original assignment mode

  • Before use
    
  • After use (builder mode, widely used in Feign source code)
    
• @Slf4j
  lombok provides, equivalent to

    public static final Logger LOGGER =
        LoggerFactory.getLogger(UserCenterApplication.class);

/**
 * This annotation is valid for classes and enumerations.<br>
 * @see <a href="https://www.slf4j.org/api/org/slf4j/Logger.html">org.slf4j.Logger</a>
 * @see <a href="https://www.slf4j.org/api/org/slf4j/LoggerFactory.html#getLogger(java.lang.Class)">org.slf4j.LoggerFactory#getLogger(java.lang.Class)</a>

@Retention(RetentionPolicy.SOURCE)
@Target(ElementType.TYPE)
public @interface Slf4j {
    /** @return The category of the constructed Logger. By default, it will use the type where the annotation is placed. */
    String topic() default "";
