搞了好久，终于终于调通了
最开始导入的包

<dependency>
            <groupId>org.apache.tomcat</groupId>
            <artifactId>servlet-api</artifactId>
            <version>6.0.29</version>
        </dependency>
        <dependency>
            <groupId>javax.servlet.jsp</groupId>
            <artifactId>jsp-api</artifactId>
            <version>2.1</version>
        </dependency>
        <dependency>
            <groupId>javax.servlet.jsp.jstl</groupId>
            <artifactId>jstl-api</artifactId>
            <version>1.2</version>
        </dependency>
        <dependency>
            <groupId>taglibs</groupId>
            <artifactId>standard</artifactId>
            <version>1.1.2</version>
        </dependency>

网上都说把依赖放到/WEB-INF/lib目录下,还有就是stackoverflow上有说standard-1.1.2.jar 和 jstl-api.jar 存在冲突，包含了jstl1.1和jstl1.2，然而我把包改为provide还是没有用，于是把tomcat路径下lib目录里的standard删了，难过香菇，最后重新弄了一个tomcat8.5的版本自己找了一些新的包，成功了！

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

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jsp-api</artifactId>
            <version>2.0</version>
            <scope>provided</scope>
        </dependency>
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
            <scope>provided</scope>
        </dependency>

记得把包放在lib目录下
