使用STS和Spring启动创建的项目中缺少logback.xml

Question

我在STS中创建了一个Spring引导Web项目，使用的是上一版本 我收到错误，即logback.xml丢失，但我在src / main / resources

上创建

我正在附加项目结构，我包括logb​​ack.xml

编辑：我在我的logback.xml文件中添加了debug="true"，日志显示了更多内容，我刚刚更新了。我可以看到首先找到logback.xml，但在某些时候它再次被要求，但是这次没有找到。

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="true">
  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>

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

Answer 1

您已使用值logging.config配置classpath:logback.xml属性，但类路径中没有logback.xml文件。

您需要提供logback.xml配置文件或删除logging.config的配置，并允许Boot使用其默认的Logback配置。

Answer 2

上一版本的工作似乎是1.2.8。 在我的Windows机器上，Spring boot 1.3和1.4根本不起作用。

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.8.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

Answer 3

我遇到了同样的问题。在我的例子中，pom.xml是过滤文件，因此它没有看到.xml的logback文件。

<resource>
            <directory>src/main/resources/</directory>
            <filtering>true</filtering>
            <includes>
                <include>**/*.jpg</include>
                <include>**/*.properties</include>
            </includes>
</resource>

您可以将.xml包含在包含会话中。

Answer 4

如果您使用Maven构建应用程序，则需要确保告诉Maven在jar中包含resources文件夹。

我遇到了这个问题并在我们的科技博客中写了一篇名为Switching logging to logback的文章。博客（点）artifact-software（dot）com（斜杠）tech是网站。

<testResources>
  <testResource>
    <directory>${project.basedir}/src/test/resources</directory>
  </testResource>
</testResources>

需要在构建部分中，以便将测试资源放入测试设置中。

需要添加类似的部分才能将其放入生产罐中。
