Question

当我向ContextLoaderListener添加web.xml时，会收到资源未找到的消息（404）。当我从web.xml删除侦听器类，然后我的index.php正在运行但添加

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

这两行给了我资源未找到错误 eclipse kepler 版本。当我在web.xml中添加这两行并准备代码时，它就是这个错误：< / LI>

java.lang.IllegalStateException：找不到WebApplicationContext：没有注册ContextLoaderListener？

我很努力，我是Spring框架的新手。你能告诉我听众或其他什么需要设置吗？

控制台出错：

Answer 1

只是添加ContextLoaderListener并不是唯一的，您还需要配置ContextLoaderListener加载的bean。 Tyicaly你为ContextLoaderListener（通过context-param contextConfigLocation）配置spring xml文件的名称，然后在这个文件中添加一些spring配置。

你也应该阅读"ContextLoaderListener or not?" question and its answers，它会让你对两个春天的背景有一些了解。它还包含web.xml

的一些示例配置

Answer 2

首先将以下内容添加到您的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd">

<!-- DispatcherServlet Context: defines this servlet's request-processing 
    infrastructure -->

<!-- Enables the Spring MVC @Controller programming model -->
<annotation-driven />

<!-- Handles HTTP GET requests for /resources/** by efficiently serving 
    up static resources in the ${webappRoot}/resources directory -->
<resources mapping="/resources/**" location="/resources/" />

<beans:bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <beans:property name="prefix" value="/WEB-INF/" />
    <beans:property name="suffix" value=".jsp" />
     <beans:property name="order" value="1" />
</beans:bean>

</beans:beans>

接下来在WEB-INF / spring文件夹中创建一个spring.xml，并根据需要进行更改。
