Make sure, following jar file included in your class path and lib folder.
确保遵循类路径和 lib 文件夹中包含的 jar 文件。
spring-core-3.0.5.RELEASE.jar
spring-core-3.0.5.RELEASE.jar
if you are using maven, make sure you have included dependency for spring-core-3xxxxx.jar file
如果您使用的是 maven，请确保已包含 spring-core-3xxxxx.jar 文件的依赖项
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${org.springframework.version}</version>
</dependency>
Note : Replace ${org.springframework.version} with version number.
注意：将 ${org.springframework.version} 替换为版本号。

org.springframework.core.io.Resourceis part of spring-core-<version>.jar
org.springframework.core.io.Resource是其一部分 spring-core-<version>.jar
But this lib is already in your lib folder. So I guess it is just a Deployment Problem. -- Try to clean your server and redeploy your application.
但是这个 lib 已经在你的 lib 文件夹中了。所以我想这只是一个部署问题。-- 尝试清理您的服务器并重新部署您的应用程序。

Right-Click on your project -> Properties -> Deployment Assembly.
右键单击您的项目 -> 属性 -> 部署程序集。
On the Left-hand panel Click 'Add' and add the 'Project and External Dependencies'.
在左侧面板上单击“添加”并添加“项目和外部依赖项”。
'Project and External Dependencies' will have all the spring related jars deployed along with your application
“项目和外部依赖项”将与您的应用程序一起部署所有与 spring 相关的 jar

There is a version conflict between jar/dependency please check all version of spring is same. if you use maven remove version of dependency and use Spring.io dependency.it handle version conflict. Add this in your pom
jar/依赖项之间存在版本冲突，请检查所有版本的 spring 是否相同。如果您使用 maven 删除依赖版本并使用 Spring.io dependency.it 处理版本冲突。在你的 pom 中添加这个
<dependency>
<groupId>io.spring.platform</groupId>
<artifactId>platform-bom</artifactId>
<version>2.0.1.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>

I received same error despite jar being in lib directory & added to deployment assembly in Eclipse.
尽管 jar 在 lib 目录中并添加到 Eclipse 中的部署程序集，但我收到了同样的错误。
So I doubted two things ,
所以我怀疑两件事，
1.Some Weblogic cache issue - as this app was deployed before & I was trying to redeploy after some changes
1. 一些 Weblogic 缓存问题 - 因为这个应用程序是之前部署的，我试图在一些更改后重新部署
2.Jar itself is corrupt due to partial download etc
2.由于部分下载等原因，Jar本身已损坏
So I re downloaded the jar & deleted everything in directory - ..\Oracle_Home\user_projects\domains\base_domain\liband redeployed again & all went well.
所以我重新下载了 jar 并删除了目录中的所有内容 - ..\Oracle_Home\user_projects\domains\base_domain\lib并再次重新部署并且一切顺利。
