###73.1.1 配置logback只输出到文件 如果想禁用控制台日志记录，只将输出写入文件中，你需要一个只导入`file-appender.xml`而不是`console-appender.xml`的自定义`logback-spring.xml`： ```xml <?xml version="1.0" encoding="UTF-8"?> <configuration> <include resource="org/springframework/boot/logging/logback/defaults.xml" /> <property name="LOG_FILE" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-/tmp}}/}spring.log}"/> <include resource="org/springframework/boot/logging/logback/file-appender.xml" /> <root level="INFO"> <appender-ref ref="FILE" /> </root> </configuration> ``` 你还需要将`logging.file`添加到`application.properties`： ```properties logging.file=myapplication.log ```
