9、Lombok

Project Lombok is a java library that automatically plugs into your editor and build tools, spicing up your java.
Never write another getter or equals method again, with one annotation your class has a fully featured builder, Automate your logging variables, and much more.

使用步骤：

1. 在IDEA中安装Lombok插件

2. 在项目中导入lombok的jar包

    <!-- https://mvnrepository.com/artifact/org.projectlombok/lombok -->
           <dependency>
               <groupId>org.projectlombok</groupId>
               <artifactId>lombok</artifactId>
               <version>1.18.10</version>
           </dependency>

3. 在实体类上加注解即可

   @Getter and @Setter
   @FieldNameConstants
   @ToString
   @EqualsAndHashCode
   @AllArgsConstructor, @RequiredArgsConstructor and @NoArgsConstructor
   @Log, @Log4j, @Log4j2, @Slf4j, @XSlf4j, @CommonsLog, @JBossLog, @Flogger, @CustomLog
   @Data
   @Builder
   @SuperBuilder
   @Singular
   @Delegate
   @Value
   @Accessors
   @Wither
   @With
   @SneakyThrows
   @val
   @var
   experimental @var
   @UtilityClass
   Lombok config system

说明：

@Data:无参构造，get、set、toSring、hashcode、equals
@AllArgsConstructor
@NoArgsConstructor
@ToString
@EqualsAndHashCode
