Ehcache日志记录级别

Question

I find a lot of examples of how to change Ehcache logging level for slf4j and logback ( 1 , 2 ). But how to do the same if my application uses JUL for logging?

logging.properties

.level=INFO

# Handlers
handlers = org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
org.apache.juli.FileHandler.level = INFO

java.util.logging.ConsoleHandler.level = INFO
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

# this has no visible effect on logging:
net.sf.ehcache=ALL

dependencies

<dependency>
    <groupId>net.sf.ehcache</groupId>
    <artifactId>ehcache</artifactId>
    <version>2.10.4</version>
</dependency>
<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-ehcache</artifactId>
    <version>4.3.11.Final</version>
</dependency>

Answer 1

Set the logging level by adding .level for the property in the logging properties file. Can be applied to packages as well as individual classes/loggers.

# This should have a bigger effect
net.sf.ehcache.level=ALL

Now this will allow for logging all levels for net.sf.ehcache . Note, that your log handler must also permit logging on that level, so if you need to log more detailed than INFO for a handler you must change that detail level as well. For instance:

java.util.logging.ConsoleHandler.level = ALL

To combine all of this for you logging properties example like this:

.level=INFO

# Handlers
handlers = org.apache.juli.FileHandler, java.util.logging.ConsoleHandler
org.apache.juli.FileHandler.level = INFO

java.util.logging.ConsoleHandler.level = ALL
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

net.sf.ehcache.level=ALL

The above will log ehcache logging for all levels in your ConsoleHandler and up to INFO for all other loggers/classes/packages. For FileHandler everything is logged up to INFO level only.
