本文详细解析了在SpringMVC项目中配置文件上传功能时遇到的常见错误：找不到org/apache/commons/fileupload/FileItemFactory类。提供了解决方案，包括正确导入依赖和将所需jar包放置于/WEB-INF/lib目录下。

@[TOC]MultipartFile上传文件Spring MVC中加入xml上传解析器配置，启动即报错！找不到类: org/apache/commons/fileupload/FileItemFactory最全解决方法（文末附jar包资源下载）

Error creating bean with name ‘multipartResolver’: Failed to introspect bean class [org.springframework.web.multipart.commons.CommonsMultipartResolver] ; NoClassDefFoundError: org/apache/commons/fileupload/FileItemFactory

<!--    配置上传解析器，开启对上传功能的支持-->
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="maxUploadSize" value="104857600" />
        <property name="maxInMemorySize" value="4096" />
    </bean>

在写springmvc xml文件中导入上传解析器做文件上传时一直报错：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'multipartResolver': Failed to introspect bean class [org.springframework.web.multipart.commons.CommonsMultipartResolver] for lookup method metadata: could not find class that it depends on; nested exception is java.lang.NoClassDefFoundError: org/apache/commons/fileupload/FileItemFactory

1.首先检查是否导入了相关依赖jar包，第一个原因可能是缺少这个commons-fileupload包
如果是pom文件导入依赖方式即在pom文件中添加如下依赖：

<dependency>
        <groupId>commons-fileupload</groupId>
        <artifactId>commons-fileupload</artifactId>
        <version>1.3.1</version>
</dependency>

否则在项目中添加相关jar包依赖：
commons-fileupload-1.3.1.jar
commons-io-1.3.2.jar

2.如果项目中已经引入了上述两个jar包（版本不一定是上述版本），仍然报错的话
您还需要将所需的通用 jars 复制到您的/WEB-INF/lib文件夹中。
commons-fileupload-1.3.1.jar
commons-io-1.3.2.jar
原因是仅将jar依赖项添加到Eclipse项目的构建路径中并不能使它们自动在Tomcat上可用。由于缺少相关性（在lib文件夹中找不到），因此Web应用程序的部署失败。
