问题描述
是否可以配置骆驼路由以将消息发送到特定的log4j记录器?例如，我有以下记录器:
<logger name="com.me.log.mylogger" additivity="false">
<level value="debug" />
<appender-ref ref="file_appender_messages" />
</logger>
file_appender_messages只是RollingFileAppender.
然后，我尝试使用骆驼上下文中的以下内容来记录它:<to uri="log:com.me.log.mylogger?level=INFO" />
但它在命令行上输出，而不是file_appender_messages中指定的日志文件:
25-Oct-2012 11:46:44 org.apache.camel.processor.CamelLogger log INFO: [MESSAGE BODY]
我希望能够使用dffferent Loggers来获取来自不同来源的消息.我可以在消息处理器中进行操作，但理想情况下它可以在路由XML中进行配置.可以做吗?
推荐答案
我通过将记录器定义为我的应用程序XML文件中的bean
解决了这一点<bean id="myLogger" class="org.apache.log4j.Logger" factory-method="getLogger">
<constructor-arg value="com.me.log.mylogger"/>
</bean>
然后在我的路线中，当我要记录消息时，我只是将其引导到bean上的相关方法
上<to uri="bean:myLogger?method=info" />

骆驼从一段时间以来就使用SLF4J.因此，您必须首先配置SLF4J以将Log4J用作后端.在Maven中添加以下依赖性:
<dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.6.1</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.16</version> </dependency>
问题描述
Is it possible to configure a Camel route to send a message to a specific log4j logger? For example, I have the following logger:
<logger name="com.me.log.mylogger" additivity="false">
<level value="debug" />
<appender-ref ref="file_appender_messages" />
</logger>
file_appender_messages is just a RollingFileAppender.
I then try to log it using the following in my Camel context:
<to uri="log:com.me.log.mylogger?level=INFO" />
But it outputs on the command line instead of the log file specified in file_appender_messages:
25-Oct-2012 11:46:44 org.apache.camel.processor.CamelLogger log INFO: [MESSAGE BODY]
I would like to be able to use dffferent loggers for messages from different sources. I could do it in my message processors but ideally it could be configured in the route xml. Can it be done?
推荐答案
I fixed this by defining the Logger as a Bean in my application XML file
<bean id="myLogger" class="org.apache.log4j.Logger" factory-method="getLogger">
<constructor-arg value="com.me.log.mylogger"/>
</bean>
Then in my route, when I want to log the message I just direct it to the relevant method on the Bean
<to uri="bean:myLogger?method=info" />

Camel uses slf4j since some time. So you have to first configure slf4j to use log4j as backend. In maven add the following dependencies:
<dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.6.1</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.16</version> </dependency>
