类 LogTool

java.lang.Object

org.apache.velocity.tools.generic.SafeConfig

org.apache.velocity.tools.generic.LogTool

所有已实现的接口:

Serializable

@DefaultKey("log")
@ValidScope("application")
public class LogTool
extends SafeConfig
implements Serializable

This tool is used to log from within templates.

Of course, the desired log level must have been configured, using the method specific to the SLF4J implementation you are using. For instance, when using the webapp-slf4j-logger, you will use the following snippet of code in you /WEB-INF/web.xml file:

 <context-param>
   <param-name>webapp-slf4j-logger.level</param-name>
   <param-value>debug</param-value>
 </context-param>
 

You can optionnaly specify the logger name in the config (the default is to re-use the engine logger):

 <tools>
   <toolbox scope="application">
     <tool class="org.apache.velocity.tools.generic.LogTool"/>
   </toolbox>
 </tools>
