## 默认日志配置 ##

2017-06-01 13:16:37.914  INFO 1468 --- [           main] s.b.c.e.t.TomcatEmbeddedServletContainer : Tomcat started on port(s): 8090 (http)
    2017-06-01 13:16:37.918  INFO 1468 --- [           main] h.Application                            : Started Application in 3.393 seconds (JVM running for 4.049)

### 如果需要记录到文件，在application.properties中指定logging.file、logging.path ###

server.port = 8090
    debug = true
    #default logging
    logging.file = d:/work/logs/spring-rest.txt

### 生成的文件 ###

## 自定义日志配置 ##

*  Logback日志系统
    
    ### 对应配置文件logback-spring.xml ###

<?xml version="1.0" encoding="UTF-8"?>
    <configuration>
    
        <timestamp key="DayFile" datePattern="yyyyMMdd" />
    
        <appender name="FILE" class="ch.qos.logback.core.FileAppender">
            <file>d:/work/logs/spring-rest-${DayFile}.txt</file>          
            <encoder>                
                <Pattern>
                    %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
                </Pattern>         
            </encoder>               
        </appender>
    
        <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
            <layout class="ch.qos.logback.classic.PatternLayout">
                <Pattern>
                    %d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n
                </Pattern>
            </layout>
        </appender>
    
        <logger name="gs-rest-service" level="debug" additivity="false">
            <appender-ref ref="STDOUT" />
        </logger>
    
        <root level="debug">
            <appender-ref ref="STDOUT" />
            <appender-ref ref="FILE" />
        </root>
    
    </configuration>

*  使用Log4J2日志系统

### 配置使用Log4J2日志系统，需要将默认的starter-logging排除 ###

### log4j2-spring.xml配置 ###
