解决spring4.x中的MappingJacksonHttpMessageConverter错误

http://www.codeweblog.com/%E8%A7%A3%E5%86%B3spring4-x%E4%B8%AD%E7%9A%84mappingjacksonhttpmessageconverter%E9%94%99%E8%AF%AF/

在spring4.x中请用org.springframework.http.converter.json.MappingJackson2HttpMessageConverter代替。

并将maven依赖改成如下：

        <dependency>            <groupId>com.fasterxml.jackson.core</groupId>            <artifactId>jackson-core</artifactId>            <version>2.5.1</version>        </dependency>        <dependency>            <groupId>com.fasterxml.jackson.core</groupId>            <artifactId>jackson-databind</artifactId>            <version>2.5.1</version>
        </dependency>
