Question

我们有一个spring-boot 1.0.RC1应用程序，其中配置了用于日志记录的logback和src / test / resources中的logback.xml文件。当我们从maven运行spring-boot时，似乎可以看到并遵守logback文件。（这是我们在spring-boot徽标之后所需的日志记录格式）

D:\Users\myName\My Projects\Work\my-co\my-app\src\my-app\my-app-camel>mvn  clean spring-boot:run -Dlogback.statusListenerClass=ch.qos.logback.core.status.OnConsoleStatusListener -Dlogback.configurationFile=src/test/resources/logback.xml

但是，当我们删除一个流氓logback.xml文件时，该文件会进入src / java / resources并重新运行，其他所有内容都保持不变（确保我们清除以删除目标中的那个）：

您会注意到spring-boot启动后的日志记录格式与第一个输出不同。但是，logback（在Spring-Boot启动之前）报告它在src / test / resources中看到了logback.xml，就像它第一次一样。

有兴趣的话，我们的logback.xml（在src / java / resources和src / test / resources中都是如下：

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="5 seconds">

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{40} - %msg%n</pattern>
        </encoder>
    </appender>

    <appender name="GELF" class="me.moocar.logbackgelf.GelfAppender">
        <facility>logback-gelf-test</facility>
        <graylog2ServerHost>XXX.XXX.XXX.XXX</graylog2ServerHost>

    </appender>

    <logger name="com.my-co.my-app." level="DEBUG" additivity="false">
        <appender-ref ref="STDOUT" />
    </logger>

    <logger name="org." level="DEBUG" additivity="false">
        <appender-ref ref="STDOUT" />
    </logger>

    <root level="INFO">

总而言之，似乎（尽管我可能错了）当一个logback.xml与我的spring-boot应用程序捆绑在一起时，它被看到并被使用（即在src / java / resources中），但是当我们不知道时但是，尽管有回归的最佳努力，但它被忽略了。

至于解决这个问题，我们很难过。我们猜测我们的spring-boot jar中有某些东西在某种程度上优先，或者关闭了logback，或者踩到并告诉logback忽略它刚被告知的内容并使用另一个默认值。

或者我们是愚蠢的，但看不到它。感谢所有的帮助。

Answer 1

默认策略假设如果您在类路径中没有logback.xml（或其他标准文件名之一），那么您必须对默认值感到满意（有关详细信息，请参阅LogbackLoggingSystem ）。 Spring Boot尝试统一外部配置开关以用于常见的日志记录系统，因此它会查找logging.config（它不知道logback.configurationFile）。您可以使用它（即logging.config=file:./src/test/resources/logback.xml），或确保您的配置文件位于类路径上。

Answer 2

我知道这篇文章有点旧，但在application.properties添加以下内容是基于Dave Syer的答案的快速解决方法：

logging.config=${logback.configurationFile}

Answer 3

根据Spring Boot documentation，您可以这样运行：

java -jar app.jar --logging.config=./src/test/resources/logback.xml

此外，Spring Boot尝试统一不同日志记录的属性名称。因此，JVM参数Dlogback.configurationFile is not used for Spring Boot。

Answer 4

在application.properties文件中添加logback文件路径。示例测试文件夹包含app.jar和config文件夹，如下所示
测试
|-app.jar
|-config
| --- application.properties
| --- logback.xml

然后添加 logging.config：config \\ logback.xml 。然后尝试，它将起作用

Answer 5

如果logback xml位于resources文件夹下，则可以将以下内容添加到VM选项：

java -jar App.jar -Dlogging.config=classpath:logback-local.xml

Answer 6

不太对劲。 Spring {{1>} 不受管理（即env var replacement等），但是logback仍然会接收它。至少这是我对文档和实践经验的理解。

Answer 7

假设您在config目录中具有spring logback配置，下面的命令将通过覆盖应用程序中的现有文件（如果有）来添加外部文件：

java -jar -Dlogging.config =。/ config / logback-spring.xml app.jar --spring.config.location =。/ config / application.properties

Answer 8

如果有什么与Spring相关的问题，我总是喜欢并建议先跳过Spring Guides / Reference notes，然后再跳过并提出疑问。

与Logback（Spring Boot上下文）相关的任何人都需要-Here。

运行Spring-Boot时忽略-Dlogback.configurationFile = logback.xml
