标签： java maven jstl java-ee-7

我正在尝试开发简单的java web应用程序，它显示简单的hello world但是当我尝试添加jstl时它不起作用！

这是我的项目结构 Project Structure

Web.xml中

当我从index.jsp中移除第一行，即taglib行时，一切正常。我想我已经在pom.xml中导入了所有必需的depnedencies。

请让我知道我做错了什么？

2 个答案:

答案 0 :(得分：0)

我相信这个问题在你的pom中。简单地说，容器在部署时没有认为JSTL库存在，或者存在冲突。

你直接特别包括JSTL版本1.2.1，然后还包括它的glassfish实现（所以，你想要哪个？）。

你几乎排除了玻璃鱼提供的所有东西。可能存在与您的排除无关的问题。我会一起删除glassfish的依赖关系，看看它是否更好。

你可以删除它们，只需尝试这个：

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

答案 1 :(得分：0)

试试这个：
- 点击你的maven项目;
- 到“maven”，然后点击“更新项目”。

它对我有用。
