使用Spring Mvc 4.x和Hibernate 4.x創建Web應用程序。我在servlet中配置了下面的代碼，但它沒有取得類文件。每次運行代碼時，它都會給出ClassNotFoundException。根據目錄結構類在該位置存在，但仍顯示爲ClassNotFoundException。我重新啓動eclipse，清理項目，重新部署項目，然後再次嘗試，但仍然沒有結果。請幫忙。以下是我添加的代碼。如果我對不同的項目使用相同的目錄結構的代碼，那麼一切工作正常。我也檢查過罐子，一切都已到位。嵌套異常是java.lang.ClassNotFoundException：com.util.HibernateAwareObjectMapper
<mvc:annotation-driven>
<mvc:message-converters>
<!-- HibernateAware mapper -->
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
<property name="objectMapper">
<bean class="com.util.HibernateAwareObjectMapper" />
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
下面是我得到的例外。
