Question Mappingjacksonhttpmessageconverter ClassNotFoundException

Java.lang.ClassNotFoundException:org.springframework.http.converter.json.MappingJacksonHttpMessageConverter

The use of defaultannotationhandlermapping and Annotationmethodhandleradapter is obsolete!

Spring 3.1 We should start with

Requestmappinghandlermapping to replace Defaultannotationhandlermapping,

Replace Annotationmethodhandleradapter with Requestmappinghandleradapter.

Please use Org.springframework.http.converter.json in the spring4.x. mappingjackson2httpmessageconverter instead.

and change the Maven dependency to the following:

        <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>

We used 7-zip to see the Spring-web-version.jar, we did not find mappingjacksonhttpmessageconverter this class.
