certitude | small library that makes the OS X keychain

A couple of points about your code:

• you should load hyperref after the other packages (with very few exceptions)

• whenever you find yourself in a situation where you manually insert formatting instructions in your latex document, this is almost always a sign that your are doing something wrong. For example instead of manually formatting and numbering all your theorems and definition, use one of the theorem packages like amsthm to have them formatted and numbered automatically

• it is much easier to use latex \label{}/\ref{} mechanism to automatically insert links then messing with \hypertarget etc.

• instead of manually inserting all these \item[] \textbf{Don Fernand :}, use a description environment instead of the unsuitable itemize

• place \title{} etc before the document begin to get meaningful pdf meta data

• don't use $$...$$ for display math. Use either \[..\] for unnumbered or \begin{equation}...\end{equation} for numbered

If one takes all these points into account, the problematic parts causing the errors will have vanished:

You need to make a Geometry class that has some deserialization logic, and then declare private Geometry geometry as a member of the Alert class.

This deserialization is usually performed "automagically" by Spring (specifically, by the fasterxml library provided by jackson). Since the Geometry class looks like it has some nontrivial objects, you'll also need to define a Coordinates class and 'Type' class (or Enum) that can similarly be deserialized.

Sometimes this approach can create a lot of small classes that take a lot of work to deal with. Another approach is to use the @JsonCreator annotation on a constructor of the Alert class:

If historyInterface is created by unmarshaling JSON to an interface{}, then the map has type map[string]interface{}. Use a type assertion to get the map as that type:
