Question

我正在开发一个maven项目，该项目需要apache commons文件上传依赖项来上传文件。

每当我尝试运行上传servlet时，我都会收到以下错误。

HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

exception

javax.servlet.ServletException: Servlet execution threw an exception

root cause

java.lang.NoClassDefFoundError: org/apache/commons/io/output/DeferredFileOutputStream
    org.apache.commons.fileupload.disk.DiskFileItemFactory.createItem(DiskFileItemFactory.java:199)
    org.apache.commons.fileupload.FileUploadBase.parseRequest(FileUploadBase.java:361)

    javax.servlet.http.HttpServlet.service(HttpServlet.java:754)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:847)

root cause

java.lang.ClassNotFoundException: org.apache.commons.io.output.DeferredFileOutputStream from BaseClassLoader@1e55d39{vfs:///home/programmer72/jboss-6.0.0.Final/server/default/conf/jboss-service.xml}

    javax.servlet.http.HttpServlet.service(HttpServlet.java:754)
    javax.servlet.http.HttpServlet.service(HttpServlet.java:847)

注意JBoss Web / 3.0.0-CR1日志中提供了根本原因的完整堆栈跟踪。

这是我的pom.xml

我已经查看了JSP - File upload with Apache Commons

他们似乎也面临着类似的问题

我已经在我的课程路径中有了公共资源

什么似乎是问题？

Answer 1

您可以尝试为commons-io依赖项指定备用组名称，看看是否有帮助。

<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
    <version>1.3.2</version>
</dependency>
