Spring MVC 配置文件报错：Error occured processing XML

新建一个项目时，Spring MVC 的配置文件 dispatchServlet.xml 中
<mvc:resources location="/static/js/" mapping="static/js/**"></mvc:resources>
报错：

Error occured processing XML 'org.springframework.beans.MutablePropertyValues.get(Ljava/lang/String;)Ljava/lang/Object;'.See Error Log for more details

查资料说是引用的Spring Jar包有冲突（我引用的 Spring Jar 包的版本是此时的最新版4.3.7.RELEASE），执行命令mvn dependency:tree查看依赖树，发现activiti-spring引用的spring-orm版本与我配置的 Spring 的版本不一致。

<dependency>    <groupId>org.activiti</groupId>    <artifactId>activiti-spring</artifactId>    <version>5.22.0</version></dependency>

然后我就先去掉了 activiti 相关依赖，问题依然存在。
继续看 pom.xml 文件，与 Spring 整合的依赖还有shiro-spring和mybatis-spring:

<dependency>    <groupId>org.mybatis</groupId>    <artifactId>mybatis-spring</artifactId>    <version>1.2.2</version></dependency><dependency>    <groupId>org.apache.shiro</groupId>    <artifactId>shiro-spring</artifactId>    <version>1.2.2</version></dependency>

我试着把shiro-spring和mybatis-spring改成最新的版本，问题依旧没有解决。

<dependency>    <groupId>org.mybatis</groupId>    <artifactId>mybatis-spring</artifactId>    <version>1.3.1</version></dependency><dependency>    <groupId>org.apache.shiro</groupId>    <artifactId>shiro-spring</artifactId>    <version>1.3.2</version></dependency>

最后，我把 Spring Jar 包的版本由 4.3.7.RELEASE 改为 4.2.6.RELEASE ，问题就解决了。

错误的具体原因我没有找到，我猜可能是因为与 Spring 整合的其它框架目前还不支持 Spring 的最新版本。

附 pom.xml 配置：
