java.lang.ClassNotFoundException：org.springframework.web.servlet.DispatcherServlet error [英] java.lang.ClassNotFoundException: org.springframework.web.servlet.DispatcherServlet error

问题描述

不知道为什么我得到这个错误。很多类似的问题在这里，但没有一个为我工作，直到现在。

Not sure why am I getting this error. Lots of similar questions here but none have worked for me till now.

我的常春藤文件是

<ivy-module version="2.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:noNamespaceSchemaLocation="http://ant.apache.org/ivy/schemas/ivy.xsd">
    <info
        organisation=""
        module="knoxWeb"
        status="integration">
    </info>

        <dependency org="org.springframework" name="spring-beans" rev="4.0.3.RELEASE"/>
    </dependencies>
</ivy-module>

我的web.xml是

<?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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

我已经解决了常春藤。仍然收到错误。我也可以在我的日食中看到Class。

I have resolved ivy. Still getting the error. Also i can see the Class in my eclipse.

我真的坚持这个。任何帮助或建议是赞赏。

I am really stuck at this. Any help or suggestion is appreciated.

PS：我还尝试添加依赖关系org =org.springframeworkname =springrev =2.5.6/> 但常春藤没有解决。我得到

PS : I also tried adding < dependency org="org.springframework" name="spring" rev="2.5.6"/> but ivy does not resolve. I get

Some projects fail to be resolved

不知道这是否与上述问题有关。我正在搜索所有依赖关系信息的 http://mvnrepository.com/artifact/org.springframework

Not sure if this has anything to do with above problem. I am searching http://mvnrepository.com/artifact/org.springframework for all dependency info.

我的项目结构是

WEB-INF / lib目录为空。

WEB-INF/lib directory is empty.

推荐答案

感谢很多人的宝贵意见。你没事jar文件必须位于 WEB-INF / lib 中。或者你可以告诉Eclipse它可以在额外的位置找到罐子，而不仅仅是 WEB-INF / lib 。

Thanks a lot guys for your valuable comments. You are all right. Jar files must be in WEB-INF/lib. Or you can tell Eclipse that it can find the jars in additional location and not just WEB-INF/lib.

我们该如何做？

• 右键单击项目并选择属性。现在去部署程序集。

• 现在选择添加并选择Java构建路径条目。

• 自动填充Ivy选项。选择这个。

• 你已经完成了。 Classnotfound异常消失。
