Class GridJavaLogger

java.lang.Object
  org.gridgain.grid.lang.GridMetadataAwareAdapter
      org.gridgain.grid.logger.java.GridJavaLogger

All Implemented Interfaces:

Serializable, Cloneable, GridMetadataAware, GridLogger

public class GridJavaLogger
extends GridMetadataAwareAdapter
implements GridLogger

Logger to use with Java logging. Implementation simply delegates to Java Logging.

Here is an example of configuring Java logger in GridGain configuration Spring file to work over log4j implementation. Note that we use the same configuration file as we provide by default:

      ...
      <property name="gridLogger">
          <bean class="org.gridgain.grid.logger.java.GridJavaLogger">
              <constructor-arg type="java.util.logging.Logger">
                  <bean class="java.util.logging.Logger">
                      <constructor-arg type="java.lang.String" value="global"/>
                  </bean>
              </constructor-arg>
          </bean>
      </property>
      ...
 

or

      ...
      <property name="gridLogger">
          <bean class="org.gridgain.grid.logger.java.GridJavaLogger"/>
      </property>
      ...
 

And the same configuration if you'd like to configure GridGain in your code:

      GridConfiguration cfg = new GridConfigurationAdapter();
      ...
      GridLogger log = new GridJavaLogger(Logger.global);
      ...
      cfg.setGridLogger(log);
 

or which is actually the same:

      GridConfiguration cfg = new GridConfigurationAdapter();
      ...
      GridLogger log = new GridJavaLogger();
      ...
      cfg.setGridLogger(log);
 

Please take a look at GridLoggerResource annotation about logger injection.
