title: Hibernate value split into 2 columns. How to map?
body: <p>I got a legacy database which I want to keep as it is, but this causes some problems with hibernate.</p>
  
  <p>My current problem is, that I have the field <code>private Calendar myTradeDateTime;</code> in my POJO and this is mapped to 2 columns.</p>
  
  <p>The first column holds only the date information (e.g. '2013-05-14') and the second column holds only the time information (e.g. '10:09:12 PM'). Now I want to use hibernate to access both columns with just that 1 field. I would assume that I need some <code>@Converter</code> to deal with it, but I have no idea how that should be done and I couldn't find any info on this topic (2 columns into 1 field).</p>
  
  <p><strong>So my question is, how can I map 2 columns into 1 field in hibernate 5.3?</strong></p>
