直接去看成體系的資料http://www.hmoore.net/dahuzichengxuyuan/java-jvm 其實就是在業務當中進行日志打點 也可以收集整個項目的各種級別的日志 這里我們提供這次項目使用到的logback-spring.xml配置文件： ### ``` <?xml version="1.0" encoding="UTF-8" ?> <configuration> <appender name="consoleApp" class="ch.qos.logback.core.ConsoleAppender"> <layout class="ch.qos.logback.classic.PatternLayout"> <pattern> %date{yyyy-MM-dd HH:mm:ss.SSS} %-5level[%thread]%logger{56}.%method:%L -%msg%n </pattern> </layout> </appender> <appender name="dataApp" class="ch.qos.logback.core.rolling.RollingFileAppender"> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>INFO</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> <encoder> <pattern> `%date{yyyy-MM-dd HH:mm:ss.SSS}`%msg`%n </pattern> </encoder> <!-- 滾動策略 --> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- 路徑 --> <fileNamePattern>app_log/log/app.data.%d.log</fileNamePattern> <MaxHistory>1</MaxHistory> </rollingPolicy> </appender> <appender name="fileInfoApp" 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> %date{yyyy-MM-dd HH:mm:ss.SSS} %-5level[%thread]%logger{56}.%method:%L -%msg%n </pattern> </encoder> <!-- 滾動策略 --> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- 路徑 --> <fileNamePattern>app_log/log/app.info.%d.log</fileNamePattern> <MaxHistory>1</MaxHistory> </rollingPolicy> </appender> <appender name="fileErrorApp" class="ch.qos.logback.core.rolling.RollingFileAppender"> <filter class="ch.qos.logback.classic.filter.ThresholdFilter"> <level>ERROR</level> </filter> <encoder> <pattern> %date{yyyy-MM-dd HH:mm:ss.SSS} %-5level[%thread]%logger{56}.%method:%L -%msg%n </pattern> </encoder> <!-- 設置滾動策略 --> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- 路徑 --> <fileNamePattern>app_log/log/app.err.%d.log</fileNamePattern> <!-- 控制保留的歸檔文件的最大數量，超出數量就刪除舊文件，假設設置每個月滾動， 且<maxHistory> 是1，則只保存最近1個月的文件，刪除之前的舊文件 --> <MaxHistory>1</MaxHistory> </rollingPolicy> </appender> <!--用于統計數據--> <logger name="dataLogger"> <level value="INFO" /> <appender-ref ref="dataApp" /> </logger> <root level="INFO"> <appender-ref ref="consoleApp"/> <appender-ref ref="fileInfoApp"/> <appender-ref ref="fileErrorApp"/> </root> </configuration> ``` ### 這只是其中一種寫法 僅供參考 ###
