Class EnvironmentPropertySource

java.lang.Object
org.apache.logging.log4j.util.EnvironmentPropertySource
All Implemented Interfaces:
PropertySource

public class EnvironmentPropertySource extends Object implements PropertySource
PropertySource implementation that uses environment variables as a source. All environment variables must begin with LOG4J_ so as not to conflict with other variables. Normalized environment variables follow a scheme like this: log4j2.fooBarProperty would normalize to LOG4J_FOO_BAR_PROPERTY.
Since:
2.10.0

    • getPriority

      public int getPriority()

      Specified by:
      getPriority in interface PropertySource
      Returns:
      priority value
    • forEach

      public void forEach(BiConsumer<String,String> action)
      Description copied from interface: PropertySource
      Iterates over all properties and performs an action for each key/value pair.
      Specified by:
      forEach in interface PropertySource
      Parameters:
      action - action to perform on each key/value pair
    • getNormalForm

      public CharSequence getNormalForm(Iterable<? extends CharSequence> tokens)
      Description copied from interface: PropertySource
      Converts a list of property name tokens into a normal form. For example, a list of tokens such as "foo", "bar", "baz", might be normalized into the property name "log4j2.fooBarBaz".
      Specified by:
      getNormalForm in interface PropertySource
      Parameters:
      tokens - list of property name tokens
      Returns:
      a normalized property name using the given tokens
