For Spring4 Rest + Json POC The following App Context is enough
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="org.name.controller" />
<!-- Enables the Spring MVC @Controller programming model -->
<mvc:annotation-driven />
<mvc:resources location="/statics/" mapping="/statics/**"/>
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
Make sure you have dependency for Jackson (e.g. in maven)
<!-- jackson so spring mvc will handle json responses out of the box -->
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.3.0</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.3.0</version>
</dependency>
You do not specifically need to define MappingJackson2JsonView; MappingJackson2HttpMessageConverter/MappingJacksonHttpMessageConverter will be created automatically when jackson is the the class path (the default is only when ContentType/Accept are application/json).
Jackson1 is deprecated, but still supported if from any reason you are limited to Jackson1
