Spring MVC + JSON : fixing error 406 (Not Acceptable)

This may happen while using Spring controllers like this:

1. 
   
2. @RequestMapping(value = "/getbirds", method = RequestMethod.GET, produces = "application/json")
3.     public @ResponseBody
4.     List<Bird> getBirds(@RequestParam("term") String term) {
5. List<Bird> lst;
6. //..........
7. return lst;
8. }



@ResponseBody annotations don't use normal view resolvers, they use their own.Put this in your dispatcher-servlet:

1. <bean id="jacksonMessageConverter" class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"></bean>
2. <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
3. <property name="messageConverters">
4. <list>
5. <ref bean="jacksonMessageConverter"/>
6. </list>
7. </property>
8. </bean>

You may need to put this dependency in your pom.xml:

1. <dependency>
2.             <groupId>org.codehaus.jackson</groupId>
3.             <artifactId>jackson-mapper-asl</artifactId>
4.             <version>1.8.0</version>
5.         </dependency>
