我是第三种情况 ！ 完美解决！！

还有前提就是缺少jar包 

我在maven中导入了以下jar包

        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>jstl</artifactId>
            <version>1.2</version>
        </dependency>
    

    <dependency>
            <groupId>taglibs</groupId>
            <artifactId>standard</artifactId>
            <version>1.1.2</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.apache.taglibs/taglibs-standard-impl -->
        <dependency>
            <groupId>org.apache.taglibs</groupId>
            <artifactId>taglibs-standard-impl</artifactId>
            <version>1.2.5</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.apache.taglibs/taglibs-standard-spec -->
        <dependency>
            <groupId>org.apache.taglibs</groupId>
            <artifactId>taglibs-standard-spec</artifactId>
            <version>1.2.5</version>
        </dependency>
