title: Override Spring form error messages
body: <p>In Spring how do I override default form error massages ?</p>
  
  <p>I'm using a <code>Validator</code> and a properties file to add my own error messages, but
  how do I override messages that get printed on conversion/encoding error for example ?</p>
  
  <p>They seem to be generated automatically and I don't think are helpful for the user:</p>
  
  <pre><code>Failed to convert property value of type java.lang.String to required type java.lang.Double for property minPrice; nested exception is java.lang.NumberFormatException: 
  </code></pre>
