请帮我解决这个问题。由于这个完全阻止
答案 0 :(得分：1)
如果你看到日志： WebApplicationContextUtils.getRequiredWebApplicationContext（WebApplicationContextUtils.java:84） ... 在org.springframework.web.servlet.support.JspAwareRequestContext。（JspAwareRequestContext.java:48） 在org.springframework.web.servlet.tags.RequestContextAwareTag.doStartTag（RequestContextAwareTag.java:76） ...
RequestContext实例（即JspAwareRequestContext）提供对WebApplicationContext等当前状态的访问。 RequestContextAwareTag是需要RequestContext的所有标记的超类。 （Spring form（）标签是org.springframework.web.servlet.tags.RequestContextAwareTag的子类。
WebApplicationContextUtils中的在您的方案中，您尚未定义根WebApplicationContext（即ContextLoaderListener），因此错误。 在web.xml中包含以下代码：
<!--Root web application context-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
并创建一个空的applicationContext.xml：
