异常:javax.servlet.jsp.PageContext cannot be resolved to a type

解析JSP文件中的PageContext对象需要以下两个JAR包(版本没有具体要求):

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
</dependency>

 <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>jsp-api</artifactId>
        <version>2.0</version>
        <scope>provided</scope>
    </dependency>
