when controller method return is @responsebody , even if i put
<bean
class="org.springframework.web.servlet.view.json.MappingJacksonJsonView">
<property name="prefixJson" value="true" />
</bean>
there will no && {} insert at the front of json data. anyone knows what is reason?
JSON in @RequestBody/@ResponseBody is handled by MappingJacksonHttpMessageConverter which is configured in AnnotationMethodHandlerAdapter.messageConverters.
The easy way to configure it without interference with other features is to create a BeanPostProcessor to intercept creation of AnnotationMethodHandlerAdapter, see, for example, here.
