学习javaweb中的JSP时，需要在pom.xml导入的依赖

<dependencies>
    <!--Servlet 依赖-->
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.5</version>
    </dependency>

    <!--JSP 依赖-->
    <dependency>
        <groupId>javax.servlet.jsp</groupId>
        <artifactId>javax.servlet.jsp-api</artifactId>
        <version>2.3.3</version>
    </dependency>

    <!--JSTL 表达式的依赖-->
    <!-- https://mvnrepository.com/artifact/javax.servlet.jsp.jstl/jstl-api -->
    <dependency>
        <groupId>javax.servlet.jsp.jstl</groupId>
        <artifactId>jstl-api</artifactId>
        <version>1.2</version>
    </dependency>

    <!--standard标签库-->
    <!-- https://mvnrepository.com/artifact/taglibs/standard -->
    <dependency>
        <groupId>taglibs</groupId>
        <artifactId>standard</artifactId>
        <version>1.1.2</version>
    </dependency>

</dependencies>

还需要注意，导入这些依赖后还需要手动刷新maven，没有出现红色警报时依赖导入才成功
