注意Apache Tomcat / 6.0.37日志中提供了根本原因的完整堆栈跟踪。

2 个答案:

答案 0 :(得分：0)

  

ServletContext资源[/WEB-INF/HelloWeb-servlet.xml]无效;   嵌套异常是org.xml.sax.SAXParseException; lineNumber：9;   columnNumber：75; cvc-elt.1：找不到元素的声明   '豆'。

这表明您的HelloWeb-servlet.xml未正确创建。

您可能在该文件中缺少名称空间声明。

如果这是本教程，则您遇到问题： https://www.tutorialspoint.com/spring/spring_mvc_hello_world_example.htm

将文件夹WebContent / WEB-INF / lib中带有org.springframework前缀的所有库版本更改为3.0.7。

这是我正在使用的库：

  

common-logging-1.2.jar org.springframework.asm-3.0.7.RELEASE.jar   org.springframework.beans-3.0.7.RELEASE.jar   org.springframework.context-3.0.7.RELEASE.jar   org.springframework.core-3.0.7.RELEASE.jar   org.springframework.expression-3.0.7.RELEASE.jar   org.springframework.web-3.0.7.RELEASE.jar   org.springframework.web.servlet-3.0.7.RELEASE.jar   spring-web-5.0.7.RELEASE.jar

使用TomCat8

注意：我还删除/重新添加了war文件，并在运行前清理了项目。
