Lombok

重要

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.

简言之，使用注解方式免于手写 setter/getter 等方法。

最佳实践

@SupperBuilder不和@Data一起用

PlatformLog

@Setter
@Getter
@NoArgsConstructor
@AllArgsConstructor
@SuperBuilder
public class CommonFields {}

PlatformLogDTO

@Setter
@Getter
@NoArgsConstructor
@AllArgsConstructor
@SuperBuilder
@ToString(callSuper = true)
@EqualsAndHashCode(callSuper = true)
public class PlatformLogDTO extends CommonFields {}

PlatformLogPO

@Setter
@Getter
@AllArgsConstructor
@NoArgsConstructor
@ToString(callSuper = true)
@EqualsAndHashCode(callSuper = true)
@SuperBuilder
public class PlatformLogPO extends CommonFields {}

原因：lombok生成的构造器语义不完整：
