The Java Spring Tutorial: Learn Java's Popular Web Framework

There's a class in Java called “Properties”, which is basically a kind of Map. In Spring, whenever a bean property expects to be passed a Map, and the keys and values are both Strings, we can use a property map to supply the required map. Don't get confused between a property map, and “properties” meaning the fields of objects (beans). I noticed after making this tutorial that I had initialised my Map property to a new HashMap, which is kind of redundant since Spring will create a new Map; although it does at least allow us to run the toString() method of our bean when it has not had its property map set.
