本文整理了Java中org.slf4j.Logger类的一些代码示例，展示了Logger类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Logger类的具体详情如下：
包路径：org.slf4j.Logger
类名称：Logger

Logger介绍

[英]The org.slf4j.Logger interface is the main user entry point of SLF4J API. It is expected that logging takes place through concrete implementations of this interface.

Typical usage pattern:

import org.slf4j.Logger; 
import org.slf4j.LoggerFactory; 
public class Wombat { 
final static Logger logger = LoggerFactory.getLogger(Wombat.class); 
Integer t; 
Integer oldT; 
public void setTemperature(Integer temperature) { 
oldT = t;         
t = temperature; 
logger.debug("Temperature set to {}. Old temperature was {}.", t, oldT); 
if(temperature.intValue() > 50) { 
logger.info("Temperature has risen above 50 degrees."); 
} 
} 
}

[中]组织。slf4j。Logger接口是SLF4J API的主要用户入口点。预期通过该接口的具体实现进行日志记录。
####典型的使用模式：

import org.slf4j.Logger; 
import org.slf4j.LoggerFactory; 
public class Wombat { 
final static Logger logger = LoggerFactory.getLogger(Wombat.class); 
Integer t; 
Integer oldT; 
public void setTemperature(Integer temperature) { 
oldT = t;         
t = temperature; 
logger.debug("Temperature set to {}. Old temperature was {}.", t, oldT); 
if(temperature.intValue() > 50) { 
logger.info("Temperature has risen above 50 degrees."); 
} 
} 
}
