java - 实现 ServletWrappingController 时出现未知异常

Question

我一直致力于实现 ServletWrappingController 方法，但遇到了一些问题。这是我的配置...

<!-- Setup Spring ServletWrappers -->
<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="mappings">
        <props>
            <prop key="/spellchecker/google-spellchecker.do">tinyMCESpellCheckerWrappingController</prop>
        </props>
    </property>
</bean>

<bean id="tinyMCESpellCheckerWrappingController" class="org.springframework.web.servlet.mvc.ServletWrappingController">
    <property name="servletClass">
        <value>org.tinymce.spellchecker.TinyMCESpellCheckerServlet</value>
    </property>
    <property name="servletName">
        <value>doPost</value>
    </property>
</bean>

我遇到了一些异常(exception)情况...

SEVERE: Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'urlMapping' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]: Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tinyMCESpellCheckerWrappingController' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]: Invocation of init method failed; nested exception is java.lang.InstantiationException

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'tinyMCESpellCheckerWrappingController' defined in ServletContext resource [/WEB-INF/dispatcher-servlet.xml]: Invocation of init method failed; nested exception is java.lang.InstantiationException

我在这里没有看到错误消息，所以我不确定从哪里开始调试以确定原因...

我刚刚查看了您的其他post看来 TinyMCESpellCheckerServlet 类是一个抽象类，在尝试实例化此类时导致了此问题。
