logback默认文件追加器的java位置

Question

我有一个以logback作为日志功能的J2EE web应用程序 并使用Tomcat 7作为服务器。 我现在正在使用logback控制台Pender，所以我可以转到 /var/log/tomcat7/catalina。出去看看日志

现在，我想把日志移到一个文件中。我将使用RollingFileAppender保存日志

我不想使用绝对路径比如：

<appender name="FILE" class="xxx.RollingFileAppender">
    <file>/var/log/testFile1.log</file>
    <encoder>
      <pattern>%msg%n</pattern>
    </encoder>
</appender>

我也不想使用系统环境变量，比如：

<appender name="FILE" class="xxx.RollingFileAppender">
    <file>{LOG_LOCATION}\testFile2.log</file>
    <encoder>
      <pattern>%msg%n</pattern>
    </encoder>
</appender>

如果我只在标签中写日志文件的名称，比如：

<appender name="FILE" class="xxx.RollingFileAppender">
    <file>testFile3.log</file>
    <encoder>
      <pattern>%msg%n</pattern>
    </encoder>
</appender>

我将收到错误：

我可以创建一个只有其名称的日志文件吗？ 如果是这样，Tomcat 7服务器中日志文件的默认位置在哪里

Answer 1

您需要一个相对路径。指定<file>./testFile3.log</file> 通过运行一次，检查这是在哪里创建的

请注意，这可能与用于启动应用程序的位置有关
