springboot日志工具

初体验

在spring开发中免不了要记录日志，听说有个lombok非常好用(它当然不止来记日志这么好用)
给个例子体验下

@Slf4j
public class WebSocketServer { 
    public void onOpen() {     
        log.info("a log");       
    }
}

看到没有，多么简单，只要一个注解@Slf4j，再不用去写LoggerFactory.getLogger()了

使用方法

引入依赖即可

dependencies {
	...
	compileOnly('org.projectlombok:lombok')
}
如果出现找不到log的错误提示，那就在idea搜索插件lombok进行安装后重启，如果还是出现找不到log的错误，那么就把Enable annotation processing勾选上，如下图

日志工具类

   
   

    
    lombok虽好，但我找不到一个可以在日志加前缀的设置，一般情况下我写的日志我都会加个前缀，来区分是系统产生的日志还是我写的日志，因此提供一个带有前缀的日志工具类

   
   
import org.slf4j.LoggerFactory;
