JSON - Spring MVC : How to post json data to spring MVC controller
If you want your JSON to be deserialized into some class, than you have to define method like this (and don't forget to add jsonConverter, as in previous answer):
.... method(@RequestBody MyClass data){ ... }But, if you want your method to accept JSON as String than do this:
.... method(@RequestBody String json){ ... }So, basically, if you post JSON, it means that JSON is not a parameter, it is body of the request. And eventually you have to use @RequestBody annotation, instead of @RequestParam.
You can find beautifull video tutorial of Spring Mvc and JSON here: sites.google.com/site/upida4j/example
it seems you dont have a Json Converter configured properly
like this one
<bean id="jacksonMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"></bean> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"><property name="messageConverters"> <list> <ref bean="jacksonMessageConverter"/> </list></property></bean>
