如何每天滚动 tomcat 8.0 日志，特别是本地主机日志文件

Question

正如标题中所写，我想要本地日志文件的每日滚动文件附加程序。

我在 logging.properties 文件中尝试了一些配置，如下所示：

添加了以下语句，但它不会起作用。

2localhost.org.apache.juli.AsyncFileHandler.limit = 102400 2localhost.org.apache.juli.AsyncFileHandler.count = 5

我刚刚解决了同样的问题。我认为你混淆了图书馆员，因为像限制和计数这样的属性只有java.util.logging.FileHandler，而你使用了org.apache.juli.FileHandler 的子 AsyncFileHandler。所以你的日志属性应该是这样的：

handlers = 1catalina.org.apache.juli.AsyncFileHandler, 
2localhost.org.apache.juli.AsyncFileHandler, 
3manager.org.apache.juli.AsyncFileHandler, 4host-
manager.org.apache.juli.AsyncFileHandler, java.util.logging.ConsoleHandler

.handlers = 1catalina.org.apache.juli.AsyncFileHandler, 
java.util.logging.ConsoleHandler

# For example, set the org.apache.catalina.util.LifecycleBase logger to log
# each component that extends LifecycleBase changing state:
#org.apache.catalina.util.LifecycleBase.level = FINE

# To see debug messages in TldLocationsCache, uncomment the following line:
#org.apache.jasper.compiler.TldLocationsCache.level = FINE

# To see debug messages for HTTP/2 handling, uncomment the following line:
#org.apache.coyote.http2.level = FINE

# To see debug messages for WebSocket handling, uncomment the following line:
#org.apache.tomcat.websocket.level = FINE

足够了，因为 FileHandler 包含可旋转的属性，并且它的默认值设置为 true。就像在文档模式中写的那样，日志文件名是 {prefix}{date}{suffix}，因此每个日志文件都将在午夜按此模式轮换。
