@JsonFilter throws "JsonMappingException: Can not resolve BeanPropertyFilter"
I think you could trick the filtered writer defining an empty serialize filter for the cases where you want all the properties seralized:
FilterProvider filters = new SimpleFilterProvider().addFilter("apiFilter", SimpleBeanPropertyFilter.serializeAllExcept(emptySet));
This way, when the engine looks for the "apiFilter" filter defined at the @JsonFilter
anotation, it finds it, but it will not have any effect (as will serialize all the properties).
EDIT
Also, you can call the factory method writer()
instead of filteredWriter()
:
ObjectWriter writer=null;
if(aplyFilter) {
FilterProvider filters = new SimpleFilterProvider().addFilter("apiFilter", SimpleBeanPropertyFilter.filterOutAllExcept(filterProperties));
writer=mapper.filteredWriter(filters);
} else {
writer=mapper.writer();
}
return writer.writeValueAsString(user);
I think this last solution is way cleaner, and indeed better.
For Spring Boot / Jackson configuration just add:
@Configuration
public class JacksonConfiguration {
public JacksonConfiguration(ObjectMapper objectMapper) {
objectMapper.setFilterProvider(new SimpleFilterProvider().setFailOnUnknownId(false));
}
}
I know it's already been answered but for any newcommers Jackson has actually added the ability to not fail on missing filters (JACKSON-650):
You just need to call
SimpleFilterProvider.setFailOnUnknownId(false)
and you won't get this exception.
