如何解决这个问题？
推荐答案
确保在您的类路径和lib文件夹中包含jar文件。
Make sure, following jar file included in your class path and lib folder.
spring-core -3.0.5.RELEASE.jar
spring-core-3.0.5.RELEASE.jar
如果您使用的是maven，请确保已包含spring-core-3xxxxx.jar文件的依赖项
if you are using maven, make sure you have included dependency for spring-core-3xxxxx.jar file
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${org.springframework.version}</version>
</dependency>
注意：用版本号替换$ {org.springframework.version}。
Note : Replace ${org.springframework.version} with version number.
