Here is the spring-context dependency as it is written in my pom.xml:

这是在我的 pom.xml 中编写的 spring-context 依赖项：

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>${spring-framework.version}</version>
</dependency>  

I also did a maven update project, a maven download sources, and an eclipse clean project, but none of those things have fixed this problem.

我也做了 a maven update project、 amaven download sources和 an eclipse clean project，但这些东西都没有解决这个问题。

What can I do to fix the problem?

我该怎么做才能解决问题？

Here is the cause of the exception:

下面是异常的原因：

java.lang.ClassNotFoundException: org.springframework.context.ConfigurableApplicationContext

You should add spring-contextand all the jars that this artifact depends on to the classpath of your project, Ex: org.springframework spring-context ${org.springframework.version}

您应该将spring-context这个工件依赖的所有 jar添加到您项目的类路径中，例如：org.springframework spring-context ${org.springframework.version}

EDIT:

编辑：

Right click your project -> properties -> Deployment Assembly and verify that your project dependencies are deployed to WEB-INF/lib:

右键单击您的项目 -> 属性 -> 部署程序集并验证您的项目依赖项是否已部署到 WEB-INF/lib：

EDIT:

编辑：

What really resolved the problem: right clickon server(in the servers view of eclipse) -> clean+ publish.

真正解决问题的是： 右键单击服务器（在 eclipse 的服务器视图中）-> clean+ publish。

回答by Mohammad Adil

that stack trace clearly says ClassNotFoundException

该堆栈跟踪清楚地说明 ClassNotFoundException

It seems that Spring-context.jaris not found in your class path.

似乎Spring-context.jar在您的类路径中找不到。

Try adding that jar in your class path first.

首先尝试在您的类路径中添加该 jar。

回答by tcosta

Can you see the spring jars in the "Maven Dependencies" section on the project?

你能在项目的“Maven Dependencies”部分看到spring jars吗？

If not, you can have a problem in your pom dependencies definition, or maybe update project didn't complete successfully. Try check dependencies definition and run update project again.

如果没有，您的 pom 依赖项定义可能有问题，或者更新项目可能没有成功完成。尝试检查依赖项定义并再次运行更新项目。

If so, did you try "clean..., "clean work directory" and "publish" on your server?

如果是这样，您是否在您的服务器上尝试过“清理...”、“清理工作目录”和“发布”？

Hope it helps.

希望能帮助到你。

I also had the same problem. the problem was occurred because common logging .jar file was not added in my project build path. after adding it project works fine.

我也有同样的问题。出现问题是因为我的项目构建路径中未添加公共日志记录 .jar 文件。添加它后项目工作正常。

Check your url pattern in web.xml /webapp/* replace "webapp" with your path name

检查 web.xml 中的 url 模式 /webapp/* 将“webapp”替换为您的路径名

回答by Erawat Jarus

I had same problem because of dependencies which are available in pom.xml file,some of them are corrupted.I resolve that by simply removing .m2/repository folder contents and followed this steps.

由于 pom.xml 文件中可用的依赖项，我遇到了同样的问题，其中一些已损坏。我通过简单地删除 .m2/repository 文件夹内容并遵循以下步骤来解决这个问题。

1. Run as -> Maven clean.
2. Run as -> Maven Install.(Use good internet provider).
3. maven -> Update project.

1. 运行方式 -> Maven clean。
2. 运行方式 -> Maven 安装。（使用良好的互联网提供商）。
3. maven -> 更新项目。

Hope it will help you too.

希望它也能帮助你。
