Lombok
Lombok
- java library
- plugs
- build tools
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>1.18.12</version>
</dependency>
3. 在实体类上加注解即可
用Lombok生成的实体类
package com.wang.pojo;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
@Data
@AllArgsConstructor
@NoArgsConstructor
public class User {
private int id;
private String name;
private String pwd;
}
Lombok中可用的注释
@Getter and @Setter
@FieldNameConstants
@ToString
@EqualsAndHashCode
@AllArgsConstructor, @RequiredArgsConstructor and @NoArgsConstructor
@Log, @Log4j, @Log4j2, @Slf4j, @XSlf4j, @CommonsLog, @JBossLog, @Flogger
@Data
@Builder
@Singular
@Delegate
@Value
@Accessors
@Wither
@SneakyThrows
说明:
@Data: 无参构造, getter, setter, toString, equals, hashcode
@AllArgsConstructor: 有参构造
@NoArgsConstructor: 无参构造
