java - 无法解决错误 [java.lang.IllegalStateException : No WebApplicationContext found: no ContextLoaderListener registered? ]

Question

我认为这个问题已经得到解答，但我无法弄清楚我添加的配置有什么问题，在添加身份验证“loginform.jsp”之前添加它工作正常，但在添加该代码之后，它不起作用

我的要求是超过登录后应该进入索引页面。

我无法获取该登录页面，请帮助我

我已经浏览了该链接，但它没有解决我的问题

请帮助我...

Answer 1

您需要添加ContextLoaderListener在将加载 WebApplicationContext 的 web.xml 中。也动<param-name>contextConfigLocation</param-name>脱离 servlet 并使用 <context-param> ，像这样:

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/config/SpringHibernate-servlet.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
