MappingJacksonJsonView已被废弃了:
http://static.javadoc.io/org.springframework/spring-webmvc/4.0.1.RELEASE/deprecated-list.html
而升级为MappingJackson2JsonView
因此POM.xml中的JACKSON版本请升级为:
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.6.5</version>
</dependency>
同时修改为:
<bean class="org.springframework.web.servlet.view.json.MappingJackson2JsonView">
<property name="contentType" value="application/json"/>
</bean>
