网上找了很多文章，都不是我问题的原因，看到有文章说是需要引入jsp-api.jar包，这是不对的。引入jsp-api2.0的jar包默认会引入javax.servlet-api2.4版本的jar包，而我们需要的是3.0以上的jar包。正确的pom.xml文件应该是如下：

<dependency>
   <groupId>javax.servlet</groupId>
   <artifactId>jstl</artifactId>
   <version>1.2</version>
</dependency>
<dependency>
   <groupId>javax.servlet</groupId>
   <artifactId>javax.servlet-api</artifactId>
   <version>3.1.0</version>
   <scope>provided</scope>
</dependency>
