配置日誌的兩種方式

1）在application.yml檔案中配置

server:
  servlet:
    context-path: /sell
logging:
  pattern:
    console: "%d - %msg%n"
  path: G:/workspace/sell/var/log/tomcat/    
//本地地址（自選，一般放在工程目錄下，預設名稱：spring.log）

2）在resources目錄下新建logback-spring.xml

<?xml version="1.0" encoding="UTF-8" ?>

<configuration>
    <!--新增日誌儲存器,控制檯-->
    <appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <pattern>
                %d - %msg%n
            </pattern>
        </layout>
    </appender>

    <!--新增本地的info日誌儲存-->
    <appender name="fileInLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.LevelFilter">
            <level>ERROR</level>
            <onMatch>DENY</onMatch>
            <onMismatch>ACCEPT</onMismatch>
        </filter>
        <encoder>
            <pattern>
                %d - %msg%n
            </pattern>
        </encoder>
        <!--滾動策略-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--新增路徑-->
            <fileNamePattern>G:/workspace/sell/var/log/tomcat/info.%d.log</fileNamePattern>
        </rollingPolicy>
    </appender>

    <!--新增本地的error日誌儲存-->
    <appender name="fileErrorLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>ERROR</level>
        </filter>
        <encoder>
            <pattern>
                %d - %msg%n
            </pattern>
        </encoder>
        <!--滾動策略-->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--新增路徑-->
            <fileNamePattern>G:/workspace/sell/var/log/tomcat/error.%d.log</fileNamePattern>
        </rollingPolicy>
    </appender>

    <!--指明配置項用在哪-->
    <root level="INFO">
        <!--引用日誌儲存器-->
        <appender-ref ref="consoleLog"/>
        <appender-ref ref="fileInLog"/>
        <appender-ref ref="fileErrorLog"/>
    </root>
</configuration>
