lombok使用

  • 添加lombok依赖
<!-- https://mvnrepository.com/artifact/org.projectlombok/lombok -->
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.20</version>
    <scope>provided</scope>
</dependency>
  • idea安装lombok插件
    社区版本自带

  • 编写实体类

package com.hua;


import lombok.Getter;
import lombok.Setter;
import lombok.ToString;

@Getter
@Setter
@ToString
public class Persion {

    private String gender;
    private String name;
    private int age;
}

使用

package com.hua;

public class LombokTest {
    public static void main(String[] args) {
        Persion persion = new Persion();
        persion.setAge(23);
        persion.setName("sss");
        persion.setGender("男");
        System.out.println(persion);
    }
}
package com.hua;

public class LombokTest {
    public static void main(String[] args) {
        Persion persion = new Persion.PersionBuilder().age(23)
                .name("ssss")
                .gender("男").build();
        System.out.println(persion);
    }
}

就可以看到使用注解的效果了

  • 常用注解
@Data
@ToString
@Getter
@Setter
@AllArgsConstructor
@NoArgsConstructor
@Builder
