RepositoryRestMvcConfiguration 无法转换为 javax.servlet.Servlet

Question

我正在尝试将一个 war 文件部署到 tomcat，但日志文件显示以下异常：

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

这里是 build.gradle 文件

repositories {

    mavenCentral()
}

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

    //Mail Jar

} 

这是我的 web.xml 文件。

<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>

我尝试排除“javax.servlet-api”，但无济于事。

如果有人可以帮助我找出这个异常背后的原因，那将是非常有帮助的。

谢谢

Answer 1

犯了一个愚蠢的错误，而不是使用

“org.springframework.data.rest.webmvc.RepositoryRestDispatcherServlet”

，我用过

“org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfiguration”

.

希望其他人看到这篇文章后不要犯同样的错误
