| <div class="block">A filter that 'and's the results of any number of contained filters together. |
| |
| For the filter to process events, all contained filters must return Filter.ACCEPT. |
| |
| If the contained filters do not return Filter.ACCEPT, Filter.NEUTRAL is returned. |
| |
| If acceptOnMatch is set to true, Filter.ACCEPT is returned. |
| If acceptOnMatch is set to false, Filter.DENY is returned. |
| |
| Here is an example config that will accept only events that contain BOTH |
| a DEBUG level AND 'test' in the message: |
| |
| <appender name="STDOUT" class="org.apache.log4j.ConsoleAppender"> |
| <filter class="org.apache.log4j.filter.AndFilter"> |
| <filter class="org.apache.log4j.filter.LevelMatchFilter"> |
| <param name="levelToMatch" value="DEBUG" /> |
| <param name="acceptOnMatch" value="true" /> |
| </filter> |
| <filter class="org.apache.log4j.filter.StringMatchFilter"> |
| <param name="stringToMatch" value="test" /> |
| <param name="acceptOnMatch" value="true" /> |
| </filter> |
| <param name="acceptOnMatch" value="false"/> |
| </filter> |
| <filter class="org.apache.log4j.filter.DenyAllFilter"/> |
| <layout class="org.apache.log4j.SimpleLayout"/> |
| </appender> |
| |
| To accept all events EXCEPT those events that contain a |
| DEBUG level and 'test' in the message: |
| change the AndFilter's acceptOnMatch param to false and remove the DenyAllFilter |
| |
| NOTE: If you are defining a filter that is only relying on logging event content |
| (no external or filter-managed state), you could opt instead |
| to use an ExpressionFilter with one of the following expressions: |
| |
| LEVEL == DEBUG && MSG ~= 'test' |
| or |
| ! ( LEVEL == DEBUG && MSG ~= 'test' ) |
| |
| XML configuration of this filter requires use of either log4j 1.2.15 or later or |
| org.apache.log4j.rolling.DOMConfigurator.</div> |
