title: Spring RestTemplate with Jackson throws "Can not resolve BeanPropertyFilter" when using @JsonFilter
body: <p>Can I specify the Jackson <code>ObjectMapper</code> that Spring's <code>RestTemplate</code> uses?</p>
  <p>I'm not 100% that's what I need to do but see below for details.</p>
  <p><strong>Background:</strong>
  With help from <a href="https://stackoverflow.com/questions/9314735/how-to-return-a-partial-json-response-using-java">this StackOverflow post</a> I added @JsonFilter to my domain class and edited my jax-rs web service (implemented in CXF).  I'm now successfully able to dynamically select which domain class fields to return in my RESTful API.  So far so good.</p>
  <p>I'm using Spring's RestTemplate in my JUnit tests to test my RESTful API.  This was working fine until I added @JasonFilter to my domain class.  Now I'm getting the following exception:</p>
  <blockquote>
  <p>org.springframework.web.client.ResourceAccessException: I/O error: Can not resolve BeanPropertyFilter with id 'apiFilter'; no FilterProvider configured; nested exception is org.codehaus.jackson.map.JsonMappingException: Can not resolve BeanPropertyFilter with id 'apiFilter'; no FilterProvider configured</p>
  <p>at org.springframework.web.client.RestTemplate.doExecute(RestTemplate.java:453)</p>
  <p>rest of stack trace omitted for brevity</p>
  <p>Caused by: org.codehaus.jackson.map.JsonMappingException: Can not resolve BeanPropertyFilter with id 'apiFilter'; no FilterProvider configured</p>
  <p>at org.codehaus.jackson.map.ser.BeanSerializer.findFilter(BeanSerializer.java:252)</p>
  </blockquote>
  <p>I was getting a similar problem on the server side and was able to resolve it (with help from <a href="https://stackoverflow.com/questions/9382094/jsonfilter-throws-jsonmappingexception-can-not-resolve-beanpropertyfilter">this post</a>) by giving a <code>FilterProvider</code> to the Jackson <code>ObjectMapper</code> as follows:</p>
  <pre><code>ObjectMapper mapper = new ObjectMapper();
  FilterProvider filters = new SimpleFilterProvider().addFilter(&quot;apiFilter&quot;, SimpleBeanPropertyFilter.filterOutAllExcept(filterProperties));
  </code></pre>
  <p>Can I do something similar on the RestTemplate side?  Any ideas of how to solve this issue are appreciated.</p>
  <p>Just to be clear, on the client RestTemplate side I do not want to filter the domain object properties at all.</p>
