解决下面报错的办法：
把pom.xml中下面两个dependency的version去掉。
<dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <!--<version>4.3.2.RELEASE</version>--> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <!--<version>4.3.2.RELEASE</version>--> </dependency>
看看实际使用version:4.2.0.RC1
