一、简介
支持日志框架：Java Util Logging, Log4J2 and Logback，默认是使用logback
对于日志的快捷方式：@Slf4j注解
注意：@Slf4j注解需要导入lombok包，pom如下：
<dependency> <groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
</dependency>
对于log的connot resolve symbol log的红叉提示，解决：
1.用快捷键Ctrl+Alt+S打开：Settings→Plugins→Browse repositories
2.输入lom后选择Install，安装插件
logback配置方式
spring boot默认会加载classpath:logback-spring.xml或者classpath:logback-spring.groovy
使用自定义配置文件，配置方式为：
logging.config=classpath:logback-roncoo.xml
注意：不要使用logback这个来命名，否则spring boot将不能完全实例化
logback-spring.xml：
<?xml version="1.0" encoding="UTF-8"?><configuration> <!-- 文件输出格式 --> <property name="PATTERN" value="%-12(%d{yyyy-MM-dd HH:mm:ss.SSS}) |-%-5level [%thread] %c [%L] -| %msg%n" /> <!-- test文件路径 --> <property name="TEST_FILE_PATH" value="G:/workspace/logs_workspace/hystrix-dashboard/logs" /> <!-- pro文件路径 --> <property name="PRO_FILE_PATH" value="/opt/hystrix-dashboard/logs" /> <!-- 开发环境 --> <springProfile name="dev"> <appender name="CONSOLE2" class="ch.qos.logback.classic.net.SMTPAppender"> <smtpHost>smtp.163.com</smtpHost> <username>发送的@163.com</username> <password>密码</password> <to>a1754966750@qq.com</to> <from>发送的@163.com</from> <subject>hystrix-dashboard</subject> <layout class="ch.qos.logback.classic.html.HTMLLayout" > <pattern>${PATTERN}</pattern> </layout> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <!--满足结果就写入,不满足结果就拒绝写入 --> <level>ERROR</level> <onMatch>ACCEPT</onMatch> <onMismatch>DENY</onMismatch> </filter> </appender> <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>${PATTERN}</pattern> </encoder> <filter class="ch.qos.logback.classic.filter.LevelFilter"> <!--满足结果就写入,不满足结果就拒绝写入 --> <level>debug</level> </filter> </appender> <logger name="com.example.demo" level="info"/> <logger name="org.springframework" level="info"/> <logger name="org.mybatis" level="debug"/> <logger name="org.apache" level="info"/> <logger name="org.hibernate" level="info"/> <logger name="com.netflix" level="info"/> <root> <appender-ref ref="CONSOLE2" /> <appender-ref ref="CONSOLE" /> </root> </springProfile> <!-- 测试环境 --> <springProfile name="test"> <!-- 每天产生一个文件 --> <appender name="TEST-FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <!-- 文件路径 --> <file>${TEST_FILE_PATH}</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- 文件名称 --> <fileNamePattern>${TEST_FILE_PATH}/info.%d{yyyy-MM-dd}.log</fileNamePattern> <!-- 文件最大保存历史数量 --> <MaxHistory>100</MaxHistory> </rollingPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <pattern>${PATTERN}</pattern> </layout> </appender> <root level="info"> <appender-ref ref="TEST-FILE" /> </root> </springProfile> <!-- 生产环境 --> <springProfile name="prod"> <appender name="PROD_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${PRO_FILE_PATH}</file> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <fileNamePattern>${PRO_FILE_PATH}/warn.%d{yyyy-MM-dd}.log</fileNamePattern> <MaxHistory>100</MaxHistory> </rollingPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <pattern>${PATTERN}</pattern> </layout> </appender> <root level="warn"> <appender-ref ref="PROD_FILE" /> </root> </springProfile></configuration>
