Question

我收到了错误

java.lang.ClassNotFoundException：org.springframework.web.context.ContextLoaderListener

仅当我在＆＃34; Spring Security＆＃34;之间包含以下代码时才进行部署和＃34;结束Spring Security＆＃34;在文件web.xml中。如果我删除XML中的这部分代码，一切正常。

造成此错误的原因是什么？如何解决？

Answer 1

导致此错误的常见问题错误地包含在spring jar中你没有提到你的ide，所以我假设你正在使用eclipse 解决方法是

1.双击用于部署的服务器

2.单击打开启动配置 - 类路径选项卡

3.单击“添加外部罐子”

4.add spring jar

5.运行你的申请

Answer 2

我创建了一个示例项目，详细说明了我遇到的两个问题：
＆GT; Spring安全版：3.2.3.RELEASE
将它改为3.1.6.RELEASE //（虽然这种情况不应该给出错误）
＆GT;在给定的pom你没有添加spring-mvc jar
添加它之后，它适用于我

Answer 3

改变

 <context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
    /WEB-INF/spring-security.xml
</param-value>

for in applicationContext.xml

<import resource="spring-security.xml" />

解决了问题

java.lang.ClassNotFoundException：org.springframework.web.context.ContextLoaderListener添加spring-security
