如何在Spring Boot中禁用logback ConsoleAppender

Question

我正在使用Spring Boot构建命令行应用程序.在此类应用程序中,日志记录控制台日志记录不合适.如何完全禁用控制台appender,但仍然使用默认的Spring Boot支持文件appender ？

我在这里创建了一个功能请求,以便更简单地支持此功能:

Answer 1

使用Spring Boot 1.3.0,我创建了一个文件logback-spring.xml(src/main/resources包含以下内容:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/defaults.xml" />
    <springProfile name="dev">
        <include resource="org/springframework/boot/logging/logback/console-appender.xml" />
        <root level="INFO">
            <appender-ref ref="CONSOLE" />
        </root>
    </springProfile>

    <springProfile name="staging,prod">
        <include resource="org/springframework/boot/logging/logback/file-appender.xml" />
        <root level="INFO">
            <appender-ref ref="FILE" />
        </root>
    </springProfile>
</configuration>

此外,我添加了logging.file属性application-staging.properties并application-prod.properties指定文件名应该是什么.

这将记录到控制台dev以及文件staging或prod配置文件.

只需添加一个名为logback.xmlin 的文件,src/main/resources其中包含(从Spring Boot的源代码中除了控制台部分之外的复制逐字复制):

<?xml version="1.0" encoding="UTF-8"?>
<configuration>


    <property name="LOG_FILE" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-/tmp}}/}spring.log}"/>
    <property name="FILE_LOG_PATTERN" value="%d{yyyy-MM-dd HH:mm:ss.SSS} %5p ${PID:- } [%t] --- %-40.40logger{39} : %m%n%wex"/>

    <appender name="FILE"
              class="ch.qos.logback.core.rolling.RollingFileAppender">
        <encoder>
            <pattern>${FILE_LOG_PATTERN}</pattern>
        </encoder>
        <file>${LOG_FILE}</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
            <fileNamePattern>${LOG_FILE}.%i</fileNamePattern>
        </rollingPolicy>
        <triggeringPolicy
                class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
            <MaxFileSize>10MB</MaxFileSize>
        </triggeringPolicy>
    </appender>

    <root level="INFO">
        <appender-ref ref="FILE" />
    </root>

</configuration>

注意

<property name="LOG_FILE" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-/tmp}}/}spring.log}"/>

需要支持从Spring Boot logging.file和的设置日志文件logging.path.

如果您只想设置一些标准日志文件,则可以在上面的属性中设置它的路径.

在较新版本的Spring Boot中,您可以轻松地包含base.xmlSpring Boot中的内容并创建以下内容logback.xml.

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <include resource="org/springframework/boot/logging/logback/base.xml" />

    <root level="INFO">
        <appender-ref ref="FILE" />
    </root>
</configuration>

为了使这个工作在Spring Boot 1.5.x和2.0.0.M4上,我添加了一个名为的文件logback-spring.xml,并将其添加到resources目录中.该文件可能如下所示

<?xml version="1.0" encoding="UTF-8"?>
<configuration>


    <property name="LOG_FILE" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-/tmp}}/}spring.log}"/>
    <property name="FILE_LOG_PATTERN" value="%d{yyyy-MM-dd HH:mm:ss.SSS} %5p ${PID:- } [%t] --- %-40.40logger{39} : %m%n"/>

    <appender name="FILE"
              class="ch.qos.logback.core.rolling.RollingFileAppender">
        <encoder>
            <pattern>${FILE_LOG_PATTERN}</pattern>
        </encoder>
        <file>${LOG_FILE}</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
            <fileNamePattern>${LOG_FILE}.%i</fileNamePattern>
        </rollingPolicy>
        <triggeringPolicy
                class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
            <MaxFileSize>10MB</MaxFileSize>
        </triggeringPolicy>
    </appender>

    <root level="INFO">
        <appender-ref ref="FILE" />
    </root>

</configuration>
