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--<pom.xml>

    <dependencies>
        <!-- Source: https://mvnrepository.com/artifact/org.projectlombok/lombok -->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.38</version>
        </dependency>
    </dependencies>

3、在实体类上加注解--<User.java>

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
    private int id;
    private String name;
    private String password;
    
}

@Getter and @Setter
@FieldNameConstants
@ToString
@EqualsAndHashCode
@AllArgsConstructor, @RequiredArgsConstructor and @NoArgsConstructor
@Log, @Log4j, @Log4j2, @Slf4j, @XSlf4j, @CommonsLog, @JBossLog, @Flogger, @CustomLog
@Data
@Builder
@SuperBuilder
@Singular
@Jacksonized
@Delegate
@Value
@Accessors
@Tolerate
@Wither
@With
@SneakyThrows
@StandardException
@val
@var
experimental @var
@UtilityClass
Lombok config system
Code inspections
Refactoring actions (lombok and delombok)

@Data:无参构造，get、set、tostring、hashcode、equals
@AllArgsConstructor
