public class MappingJackson2HttpMessageConverter extends AbstractJackson2HttpMessageConverter
HttpMessageConverter
that can read and
write JSON using Jackson 2.x's ObjectMapper
.
This converter can be used to bind to typed beans, or untyped HashMap
instances.
By default, this converter supports application/json
and application/*+json
with UTF-8
character set. This can be overridden by setting the
supportedMediaTypes
property.
The default constructor uses the default configuration provided by Jackson2ObjectMapperBuilder
.
Compatible with Jackson 2.6 and higher, as of Spring 4.3.

public void setPrefixJson(boolean prefixJson)
Prefixing the JSON string in this manner is used to help prevent JSON Hijacking. The prefix renders the string syntactically invalid as a script so that it cannot be hijacked. This prefix should be stripped before parsing the string as JSON.
