找不到logback.xml

Question

null

其中%classpath%是一个环境变量,它具有日志所需的.jar文件的路径,如：

• logback-access-1.1.2.jar
• logback-classic-1.1.2.jar
• logback-core-1.1.2.jar
• SLF4J-API-1.7.6.jar

这是我的logback.xml文件

<configuration>
    <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">

        <file>test.log</file>

        <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
            <fileNamePattern>tests.%i.log</fileNamePattern>
            <minIndex>1</minIndex>
        </rollingPolicy>

        <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
            <maxFileSize>2MB</maxFileSize>
        </triggeringPolicy>

        <encoder>
            <pattern>%date %level [%thread] %logger{10} [%file:%line] %msg%n</pattern>
        </encoder>

    </appender>

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

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Logback{
    private final static Logger logger = LoggerFactory.getLogger(Logback.class);

    public static void main(String[] args){
        for(int i=0;i<1000000;i++)
            logger.debug("hello");
    }
}

• \logback>java-cp.；%classpath%-dlogback.configurationfile=logback.xml logback

从日志记录文档：

1. Logback tries to find a file called logback.groovy in the classpath.
2. If no such file is found, logback tries to find a file called logback-test.xml in the classpath.
3. If no such file is found, it checks for the file logback.xml in the classpath..
4. If neither file is found, logback configures itself automatically using the BasicConfigurator which will cause logging output to be directed to the console.

像logback.groovy、logback-test.xml或logback.xml这样的配置文件应该位于类路径的哪个位置？

Configuration files such as logback.groovy, logback-test.xml or logback.xml can be located directly under any folder declared in the class path. For example, if the class path reads "c:/java/jdk15/lib/rt.jar;c:/mylibs/" then the logback.xml file should be located directly under "c:/mylibs/", that is as "c:/mylibs/logback.xml". Placing it under a sub-folder of c:/mylibs/, say, c:/mylibs/other/, will not work.

For web-applications, configuration files can be placed directly under WEB-INF/classes/.

因此需要将logback.xml放入类路径中。在一个项目中，我们遇到了类似的问题，尽管logback.xml的位置是正确的。将其重命名为logback-test.xml有所帮助。
