MultiValueMap<K, V>	Extension of the `Map` interface that stores multiple values.
PathMatcher	Strategy interface for `String`-based path matching.
PropertiesPersister	Strategy interface for persisting `java.util.Properties`, allowing for pluggable parsing strategies.
PropertyPlaceholderHelper.PlaceholderResolver	Strategy interface used to resolve replacement values for placeholders contained in Strings.
ReflectionUtils.FieldCallback	Callback interface invoked on each field in the hierarchy.
ReflectionUtils.FieldFilter	Callback optionally used to filter fields to be operated on by a field callback.
ReflectionUtils.MethodCallback	Action to take on each method.
ReflectionUtils.MethodFilter	Callback optionally used to method fields to be operated on by a method callback.
StringValueResolver	Simple strategy interface for resolving a String value.
WeakReferenceMonitor.ReleaseListener	Listener that is notified when the handle is being released.

Classes

AntPathMatcher	PathMatcher implementation for Ant-style path patterns.
Assert	Assertion utility class that assists in validating arguments.
AutoPopulatingList<E>	Simple List wrapper class that allows for elements to be automatically populated as they are requested.
CachingMapDecorator<K, V>	A simple decorator for a Map, encapsulating the workflow for caching expensive values in a target Map.
ClassUtils	Miscellaneous class utility methods.
CollectionUtils	Miscellaneous collection utility methods.
CommonsLogWriter	`java.io.Writer` adapter for a Commons Logging `Log`.
CompositeIterator<E>	Iterator that combines multiple other iterators.

FileCopyUtils	Simple utility methods for file and stream copying.
FileSystemUtils	Utility methods for working with the file system.
LinkedCaseInsensitiveMap<V>	LinkedHashMap variant that stores String keys in a case-insensitive manner, for example for key-based access in a results table.
LinkedMultiValueMap<K, V>	Simple implementation of `MultiValueMap` that wraps a LinkedHashMap, storing multiple values in a LinkedList.
Log4jConfigurer	Convenience class that features simple methods for custom log4j configuration.
MethodInvoker	Helper class that allows for specifying a method to invoke in a declarative fashion, be it static or non-static.
NumberUtils	Miscellaneous utility methods for number conversion and parsing.
ObjectUtils	Miscellaneous object utility methods.
PatternMatchUtils	Utility methods for simple pattern matching, in particular for Spring's typical "xxx", "xxx" and "xxx" pattern styles.
PropertyPlaceholderHelper	Utility class for working with Strings that have placeholder values in them.
ReflectionUtils	Simple utility class for working with the reflection API and handling reflection exceptions.
ResourceUtils	Utility methods for resolving resource locations to files in the file system.
SerializationUtils	Static utilities for serialization and deserialization.
StopWatch	Simple stop watch, allowing for timing of a number of tasks, exposing total running time and running time for each named task.
StopWatch.TaskInfo	Inner class to hold data about one task executed within the stop watch.
StringUtils	Miscellaneous String utility methods.
SystemPropertyUtils	Helper class for resolving placeholders in texts.
TypeUtils	Utility to work with Java 5 generic type parameters.
WeakReferenceMonitor	Track references to arbitrary objects using proxy and weak references.

Exceptions
