Convert bean to map
Sometimes you may want to convert an object into a map, using the JsonSerializer
exclude/include rules. This can be done with BeanSerializer
, in few steps like this:
BeanSerializer
parse beans and match properties to all include/exclude rules. Resulting map will contain all included properties of a bean. Serializing this map or the bean should give exactly the same results!
This may be handy if you have some further filtering options on some bean.
Use JsonWriter
JsonWriter
is a simple class that writes JSON to the output. You can use it to construct JSON directly, without serialization:
This can be handy when e.g. you need to wrap your serialized JSON into another simple map. Instead of creating a new Map
object you can simply use the writer with the JSON result to create the same thing, but faster.
