Question

I need to Inject a Map to a bean property and when map entries are traversed it should return them in insertion order. In Java, this is similar to the LinkedHashMap. But as I can’t find anything in spring documentation related to the ordering of tag, I’m not sure whether I can use to use it in this scenario.

Can someone please let me know the whether I can use for this purpose.

Many thanks

The default is LinkedHashMap – MapFactoryBean is used to create instances of Map. According to docs:

Simple factory for shared Map instances. Allows for central setup of
Maps via the “map” element in XML bean definitions.

and its setTargetMapClass method:

Set the class to use for the target Map. Can be populated with a fully
qualified class name when defined in a Spring application context.
Default is a linked HashMap, keeping the registration order.

so no need to use <util:map> here.
