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;

    • public class Log {
