RepositoryRestMvcConfiguration无法强制转换为javax.servlet.Servlet

Question

I am trying to deploy one war file to tomcat but the log file shows the following exception :

SEVERE: Servlet [rest] in web application [/sample] threw load() exception
java.lang.ClassCastException: org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration cannot be cast to javax.servlet.Servlet

Here is the build.gradle file

repositories {

    mavenCentral()
}

dependencies {
   providedCompile   'org.apache.tomcat:tomcat-servlet-api:7.0.37'
   providedCompile   'javax.servlet:javax.servlet-api:4.0.0-b01'

    // Spring Framework Jars 
    compile 'org.springframework:spring-context:4.1.0'

} 

And this is my web.xml file .

<web-app>
<display-name>sample Web Application</display-name>
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>
<listener>
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>WEB-INF/config/sample-servlet.xml</param-value>
</context-param>

<servlet>
    <servlet-name>rest</servlet-name>
    <servlet-class>org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration
    </servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>rest</servlet-name>
    <url-pattern>/api/*</url-pattern>
</servlet-mapping>

I have tried to exclude "javax.servlet-api " ,but with no avail .

If anyone can help me in finding the reason behind this exception ,that would be of great help .

Thanks

Answer 1

Made a silly mistake ,instead of using

"org.springframework.data.rest.webmvc.RepositoryRestDispatcherServlet"

,i used

"org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration"

.

Hope after seeing this post other people will not make the same mistake
