logback.xml日志文件配置
logback.xml日志文件配置
在项目当中日志也成为必不可少的一部分，除了再控制台上打印控制台日志以外，在服务器上运行时候日志都是记录到日志文件里面，那么日志文件一般是怎么配置的，放在哪个目录下面呢，这些都是需要我们思考的，首先我们看下日志引进都需要哪些包：<!--与日志相关的jar --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.2</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-core</artifactId> <version>1.0.13</version> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.0.13</version> </dependency>
下面就是配置文件写法，命名为logback.xml放到src/main/resources根目录下，程序会自动加载日志文件
<?xml version="1.0" encoding="UTF-8"?> <configuration> <contextName>logback-4001</contextName> <jmxConfigurator /> <!-- 日志路径 --> <property name="LOG_HOME" value=" /home/spirits/service/logs/" /> <!-- console控制台日志 --> <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender"> <layout class="ch.qos.logback.classic.PatternLayout"> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern> </layout> </appender> <!-- 程序运行日志记录-3天--> <appender name="INFO_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>${LOG_HOME}/info/spirit-info-%d{yyyy-MM-dd}.log</FileNamePattern> <MaxHistory>3</MaxHistory> <!--保存天数 --> </rollingPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n </pattern> </layout> </appender> <!-- 错误日志记录-15天 --> <appender name="ERROR_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <FileNamePattern>${LOG_HOME}/error/spirit-error-%d{yyyy-MM-dd}.log</FileNamePattern> <MaxHistory>15</MaxHistory> </rollingPolicy> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> <layout class="ch.qos.logback.classic.PatternLayout"> <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n </pattern> </layout> </appender> <root level="info"> <appender-ref ref="stdout" /> <appender-ref ref="ERROR_FILE" /> <appender-ref ref="INFO_FILE" /> </root> </configuration>
若不放到src/main/resources根目录下，则需要引入，比如此时放在src/main/resources/META-INF/logback/下，文件名为logback-test.xml,则需要在src/main/resources根目录下面新建logback.xml,配置如下：
<?xml version="1.0" encoding="UTF-8"?> <configuration> <include resource="META-INF/logback/logback-test.xml"/> </configuration>
