title: spring rest multiple filter
body: <p>i have an entity  for i.e stock table ( attribute item, quantity, weight, expiration date .. ecc)...
  how can do a dynamic query on my rest spring backend ? For i.e the user can do a query without filter but can also do a query with multiple filter for i,e quantity>0 and item = x and expiration data > yesterday... so i have to  develop the parse to accept not a fixed number of parameters. My second question is that my rest api must accept = as operator but also &lt; > >= &lt;= != to do filter query.
  Thanks</p>
