問題--JSTL和EL表達式問題

1.EL表達式不生效

記得isELIgnored=“false”

<%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %>

##JSTL表達式報錯，依賴問題

  <dependency>

      <groupId>org.glassfish.web</groupId>
      <artifactId>jstl-impl</artifactId>
      <version>1.2</version>
      <!-- 去除依賴 -->
      <exclusions>
        <exclusion>
          <groupId>javax.servlet</groupId>
          <artifactId>servlet-api</artifactId>
        </exclusion>
      </exclusions>
    </dependency>
    <!-- 導入servlet-api -->
    <dependency>
