最佳答案
尝试从<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>的<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">中删除它。我认为这是不必要的。这可能会引起问题。
更新后的bean应该如下所示:
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
