[开发工具]注解@Slf4j的使用

如果不想每次都写private final Logger logger = LoggerFactory.getLogger(当前类名.class); 可以用注解@Slf4j;
1.idea安装插件

2.pom导入依赖

<dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.6</version>
            <scope>provided</scope>
        </dependency>

3.使用

import com.xmy.constant.ShopCode;
import lombok.extern.slf4j.Slf4j;

@Slf4j
public class CastException {
    public static void cast(ShopCode shopCode) throws CustomerException {
        log.error(shopCode.toString());
        throw new CustomerException(shopCode);
    }
}
