spring boot中默认继承了logback的日志配置。
- 配置application.properties
# config logback
logging.config=classpath:logback-spring.xml
logging.path=../webLog/demo-1.0.0
logging.level.root=info
logging.path可以是相对路径,也可以是绝对路径
logging.config是logback的配置路径
- 添加loaback的配置文件 logback-spring.xml
<configuration scan="true" scanPeriod="10 seconds">
<include resource="org/springframework/boot/logging/logback/base.xml" />

<!-- hibernate日志输入 -->
<!-- <logger name="org.hibernate.type.descriptor.sql.BasicBinder" level="TRACE"
/> <logger name="org.hibernate.type.descriptor.sql.BasicExtractor" level="TRACE"
/> <logger name="org.hibernate.SQL" level="INFO" /> <logger name="org.hibernate.engine.QueryParameters"
level="INFO" /> <logger name="org.hibernate.engine.query.HQLQueryPlan" level="INFO"
/> -->
<root level="INFO">
<appender-ref ref="INFO_FILE" />
<appender-ref ref="ERROR_FILE" />
</root>
</configuration>
logback的配置文件请自行百度。
这样在具体的class中使用
private Logger logger = LoggerFactory.getLogger(getClass());
就可以打印出日志啦。
