android - Jackson annotations tutorials? -

does aware of jackson annotations tutorials? especially, how parse json array using jackson annotations? suppose have json this:

{ ... "item1": "aaa", "item2": "bbb", "fl": [      {          "item3": "ccc",          "item4": "ddd"       }   ] }  

how 1 parse json including array using jackson annotations?

i assume asking how map json java objects (parsing typically refers lower level activity of decoding json content stream representation, may or may not set of objects).

with jackson (as many other libs, genson, gson etc), have choice of either binding pojo matching structure, say:

public class value {    public string item1; // or other type 1 can bind json string   public string item2; // can alternatively use getters/setters instead of public fields   public list<entrytype> f1; } public class entrytype {   public string item3;   public string item4; } 

or reading tree representation so:

jsonnode rootnode = mapper.readtree(inputsource); 

in latter case, need traverse tree nodes find data.

as annotations: need use annotations if need change default properties of binding; mapping between json object fields , pojo property names.

for jackson-specific configuration including of annotations, see jackson-databind github project: https://github.com/fasterxml/jackson-databind/
