<title>Overriding Mapping with explicit Converters</title>
<para>When storing and querying your objects it is convenient to have a
<interfacename>MongoConverter</interfacename> instance handle the
mapping of all Java types to DBObjects. However, sometimes you may want
the <interfacename>MongoConverter</interfacename>'s do most of the work
but allow you to selectivly handle the conversion for a particular type.
To do this, register one or more one or more
<classname>org.springframework.core.convert.converter.Converter</classname>
instances with the MongoConverter.</para>
<note>
<para>Spring 3.0 introduced a core.convert package that provides a
general type conversion system. This is described in detail in the
Spring reference documentation section entitled <ulink
url="http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/validation.html#core-convert">Spring
3 Type Conversion</ulink>.</para>
</note>
<para>The <methodname>setConverters</methodname> method on
<classname>SimpleMongoConverter</classname> and
<classname>MappingMongoConverter</classname> should be used for this
purpose. The method
<methodname>afterMappingMongoConverterCreation</methodname> in
<classname>AbstractMongoConfiguration</classname> can be overriden to
configure a MappingMongoConverter.</para>
