如何使用 logback.xml 将我的 Apache camel 日志级别设置为错误

Question

我正在对 Apache camel 进行性能测试，到目前为止我能够运行 logback async 获得一些速度，

有没有在开始我的路线时甚至禁用 camel-context 的 INFO。

logback.xml:

而我的 logback.xml 配置是，

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

<configuration debug="false" scan="false">
    <statusListener class="ch.qos.logback.core.status.NopStatusListener" />

    <!-- To show the log in console -->
    <appender name="OUT" class="ch.qos.logback.core.ConsoleAppender">
        <prudent>true</prudent>
        <encoder>
            <Pattern>
                %d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
            </Pattern>
        </encoder>
    </appender>

    <logger name="org.apache.catalina.core" level="INFO" />

    <!-- DEBUG Config -->
    <logger name="logs_debug" level="DEBUG" additivity="false">
        <appender-ref ref="OUT" />
    </logger>

    <!-- INFO Config -->
    <logger name="logs_info" level="INFO" additivity="false">
        <appender-ref ref="OUT" />
    </logger>

    <!-- ERROR Config -->
    <logger name="logs_error" level="ERROR" additivity="false">
        <appender-ref ref="OUT" />
    </logger>

    <!-- To make the Logback ASYNC -->
    <appender name="ASYNC" class="ch.qos.logback.classic.AsyncAppender">
        <includeCallerData>true</includeCallerData>
        <queueSize>500</queueSize>
        <discardingThreshold>2</discardingThreshold>
        <appender-ref ref="OUT" />
    </appender>

    <!-- root Logback -->
    <root level="ERROR">
        <appender-ref ref="ASYNC" />
    </root>
</configuration>

我收到了这个回复。

Answer 1

尝试查看 link from camels 站点。

日志给出了一些选项：要使用的日志记录级别。可能的值：ERROR、WARN、INFO、DEBUG、TRACE、OFF

可以这样使用：

.log(LoggingLevel.ERROR, "some error to log")

Answer 2

我的 log4j 具有以下配置并且对我来说运行良好

<logger name="org.apache.camel" additivity="false">
        <level value="ERROR" />
        <appender-ref ref="MYAPPENDER1" />
</logger>
<root level="ERROR"> <appender-ref ref="CONSOLE" /> </root>

我认为 logback 也会是这样的。

Answer 3

不，我不这么认为，因为您正在使用 camel-maven-plugin 启动 Camel，这是一个 Maven 插件，它有自己的启动类型和在 Camel 启动之前发生的日志记录等。

如果你根本不想记录日志，那么自己将 Camel 作为 java 主应用程序启动。

现在的重点是你真的不应该在这上面浪费时间，因为启动是微不足道的，不应该在你的性能测试中进行测量。它仅在应用程序启动时运行您可能需要 tweak/tune logging/JMX/threads 以及诸如此类的东西以获得更高的性能。
