8_Lombok

使用步骤：

1. 在IDEA中安装Lombok插件
2. 在项目中导入lombok的jar包

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.10</version>
</dependency>

​ 3.在实体类上加注解

@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

@Data：无参构造，get、set、toString、hashcode、equals
@AllArgsConstructor//有了有参构造，而无参构造就没了
@NoArgsConstructor//生成无参构造
