Jakarta EE 命名空间迁移|kuuhaku的博客

一般使用JSTL时的JSP页面的头

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

有些时候可能需要添加（个人暂时没遇到过）

<%@ page isELIgnored="false" %>

在JSP页面上引入JSTL标签库

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

更改命名空间的依赖

        <!--servlet-->
<!--        <dependency>-->
<!--            <groupId>javax.servlet</groupId>-->
<!--            <artifactId>javax.servlet-api</artifactId>-->
<!--            <version>3.1.0</version>-->
<!--            <scope>provided</scope>-->
<!--        </dependency>-->
        <dependency>
            <groupId>jakarta.servlet</groupId>
            <artifactId>jakarta.servlet-api</artifactId>
            <version>6.0.0</version>
            <scope>provided</scope>
        </dependency>
        <!--jsp-->
<!--        <dependency>-->
<!--            <groupId>javax.servlet.jsp</groupId>-->
<!--            <artifactId>jsp-api</artifactId>-->
<!--            <version>2.2</version>-->
<!--            <scope>provided</scope>-->
<!--        </dependency>-->
        <dependency>
            <groupId>jakarta.servlet.jsp</groupId>
            <artifactId>jakarta.servlet.jsp-api</artifactId>
            <version>4.0.0</version>
            <scope>provided</scope>
        </dependency>

        <!--jstl-->
        <!--提供jstl的API和规范-->
<!--        <dependency>-->
<!--            <groupId>jstl</groupId>-->
<!--            <artifactId>jstl</artifactId>-->
<!--            <version>1.2</version>-->
<!--        </dependency>-->
        <dependency>
            <groupId>jakarta.servlet.jsp.jstl</groupId>
            <artifactId>jakarta.servlet.jsp.jstl-api</artifactId>

个人常用依赖坐标（不带过期命名空间的）
