2、错误原因
由错误提示可知，缺少spring-benas包
3、解决办法
将spring-beans-4.3.0.RELEASE.jar导入lib目录下或在pom.xml中添加
<!-- https://mvnrepository.com/artifact/org.springframework/spring-beans -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-beans</artifactId>
<version>4.3.0.RELEASE</version>
</dependency>
