java - Spring 找不到 Maven 依赖项中的 jar

Question

我正在开发一个 Web 应用程序，并在我的 Sercurity 上下文文件中收到错误: 在这一行找到多个注释: - 处理 XML“javax/servlet/Filter”时发生错误。请参阅错误日志了解更多详细信息 - spring-security-web jar 中的类(或其依赖项之一)不可用。你需要这些才能使用 :javax.servlet.Filter

谁能帮忙解决一下吗？我已经发布了文件、POM 和 web.xml

Answer 1

您正在使用 Servlet api，但在您的 pom.xml 中，这不是 servlet-api.jar 的条目。添加

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

在 pom.xml 中
