target

My main target here is to show how spring cloud config work with a real example

what is spring cloud config

As you know, spring cloud has many projects (modules) and spring cloud config is one of these.
His target is to help the programmer to build a server that work as configuration server and also to let the clients to get the configuration from the server.
No one force you to use spring cloud config to build this kind of stuff, but if you use it, you will save a lot of time, because, as we are going to see, with spring cloud is very simple build what i said.

Algorithm description

Quick description

Quick sort is an algorithm to sort elements (we will use a vector)

In short, the procedure for sorting is done in this way: i take a vector's element (the pivot) (for example the first element of the vector) and then i move the pivot and all the elements, with value less than the value of pivot, at left of the pivot and all the elements, with value more hight, to the right of the pivot.

Summary

In this article i want to show
- an introduction to sax
- a simple use case that dimostrate the basic functionality of SAX
- how to validate an xml document with SAX
- how to use the filters

JAXB allow binding between java objects and xml instance.
Basically with JAXB you can do 'marshall' and 'unmarshall' operations.

Marshall means the process of conversion from java objects to xml instance. With unmarshall means the opposite.

Marshall example

To start with marshalling we need at least our domain class. Suppose we have a city with many person and i want to have an xml file with a root element city wich contains more element of kind people. To do that we need one object of type city wich contains a collection of person objects
