springmvc使用表单标签报异常

Question

springmvc使用表单标签报异常:

java.lang.IllegalStateException: No WebApplicationContext found: no ContextLoaderListener registered?

引用了：<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>

再使用：“

<form:form action="addStudent" method="post">

<form:label path="name">姓名：</form:label><form:input path="name"/>

<form:textarea path="text"/>

</form:form>

”就报异常，求助。 如果不使用 上面的spring 的form 标签就不报错。

web.xml:

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns="http://java.sun.com/xml/ns/javaee"

WEB-INF 目录下有SpringMVC-servlet.xml：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

Answer 1

<servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list>这个配置错误，加上一个<servlet>     <servlet-name>SpringMVC</servlet-name>     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>     <init-param>       <param-name>contextConfigLocation</param-name>       <param-value>classpath:xxx.xml</param-value>     </init-param>     <load-on-startup>1</load-on-startup>   </servlet>   <servlet-mapping>     <servlet-name>SpringMVC</servlet-name>     <url-pattern>/</url-pattern>   </servlet-mapping>你配置文件少了一个contextConfigLocation
