Java 如何在Intellij中使用Tomcat8？

当我想运行演示时，网页显示以下错误，为什么？
是版本问题吗？我正在运行ApacheTomcat/8.0.14和springframework 4.1.1

HTTP Status 500 - Unable to compile class for JSP:
Unable to compile class for JSP:

检查您的

WEB-INF/lib

中是否没有旧的

servlet.jar

。您的构建过程可能不正确。这里也描述了这个问题：

我也有同样的问题。在pom.xml中将ServletAPI的范围设置为“提供”后，它就可以工作了

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>provided</scope>
</dependency>

javax.servlet
servlet api
2.5
假如

我曾经在Tomcat 8.0、Spring 4.1.1和IntelliJ中看到过类似的问题。尝试删除IntelliJ项目文件并重新导入项目（例如从Maven

pom.xml

文件）。（这为我解决了问题）。查看事件日志，您可能错过了邀请您下载所需库的消息。好的。非常感谢！在我换成tomcat 7后没问题是的谢谢you@Qingzi
