# 一、log4j #

基于非注解开发使用日志。

**配置`pom.xml`，添加依赖**

**引入log4j配置文件：`resouces/log4j.properties`**

# resources文件夹根目录下
    ### 配置根
    log4j.rootLogger = debug,console
    
    ### 日志输出到控制台显示
    log4j.appender.console=org.apache.log4j.ConsoleAppender
    log4j.appender.console.Target=System.out
    log4j.appender.console.layout=org.apache.log4j.PatternLayout
    log4j.appender.console.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

# 二、logback #

基于注解开发使用日志。

**配置`pom.xml`，添加依赖**

**引入 logback 配置文件：`resouces/logback.xml`**

<?xml version="1.0" encoding="UTF-8"?>
    <configuration>
        
        <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
            <encoder>
                
                <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
            </encoder>
        </appender>
        
        <root level="DEBUG">
            <appender-ref ref="STDOUT" />
        </root>
    </configuration>
