上网上找了半天，没找的一个合适的答案，最后终于在一个帖子中发现问题所在，这是一个Jar包的问题，我原来引入的jar是：
<dependency>
<groupId>javax.servlet.jsp.jstl</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
改成这样子就可以了：
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
