曾尝试搜索它，但我一直在获取...IS_UNDEFINED文件名。我只想将当前日期附加到日志文件中。logback.xml文件的任何简单示例？

这是我最近的尝试：

<Properties>
  <property name="filePattern">log_${date:yyyy-MM-dd}.log</property>
</Properties>
<appender name="FILE" class="ch.qos.logback.core.FileAppender">
  <file>${application.home:-.}/logs/${filePattern}</file>
  <encoder>
    <pattern>%date [%level] from %logger in %thread - %message%n%xException</pattern>
  </encoder>
</appender>

我正在尝试设置 aFileBasedConfigurationBuilder以便我可以使用 aPropertiesConfiguration但我得到了NoClassDefFoundError. 这是我的代码

public class Config {
  private static Properties properties;
  private static PropertiesConfiguration config;

  public static void setUp(String path) throws ConfigurationException, IOException {
    if (config == null) {
      FileBasedConfigurationBuilder<PropertiesConfiguration> builder =
          new FileBasedConfigurationBuilder<PropertiesConfiguration>(PropertiesConfiguration.class)
          .configure(new Parameters().properties()
              .setFileName("myConfig.properties")
              .setThrowExceptionOnMissing(true)
              .setListDelimiterHandler(new DefaultListDelimiterHandler(','))
              .setIncludesAllowed(false));

      config = builder.getConfiguration();

      File file = new File(path);
      FileReader reader = new FileReader(file);
      config.read(reader);
    }
  }
}

和堆栈跟踪：
