2、错误原因

     由于我使用的是spring4.1.1,而在配置文件中使用了spring3的类

     org.springframework.http.converter.json.MappingJacksonHttpMessageConverter

  

3、解决办法

(1)将spring4版本修改成spring3

(2)将spring4中配置的类

        org.springframework.http.converter.json.MappingJacksonHttpMessageConverter

        修改成

        org.springframework.http.converter.json.MappingJackson2HttpMessageConverter
