java获取资源404不可用tomcat
我试图在SpringMVC中开发一个HelloWorld示例,我已经知道Java,但我在Spring是新手,我遵循这个教程点教程:https://www.tutorialspoint.com/spring/spring_mvc_hello_world_example.htm 我遇到了一些问题,但在一瞬间它还可以正常工作,然后我转到下一个教程,然后它不再工作,即使我删除了所有新文件,我也找不到原因。 (我只是指出了教程的变化,以防这是原因,但可能这并不相关)
-这是我的网站。xml

-Hello控制器。爪哇
package com.tutorialspoint;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping("/hello")
public class HelloController {
@RequestMapping(method = RequestMethod.GET)
public String printHello(ModelMap model) {
model.addAttribute("message", "Hello Spring MVC Framework!");
return "hello";
}
}
-你好。jsp
<%@ page contentType = "text/html; charset = UTF-8" %>
<html>
<head>
<title>Hello World</title>
</head>
<body>
<h2>${message}</h2>
</body>
</html>
还有我的目录 Directories
要在Tomcat中部署它,我只需右键单击Eclipse中的项目>;出口>;WAR文件,并将其保存在Tomcat的webapps文件夹中,在那里我也有Jenkins WAR,Jenkins工作正常,我可以看到Tomcat主页也正常,所以我认为这不是Tomcat的问题,但我愿意接受建议
然后我转到localhost:8080/HelloWeb/hello
,我得到了错误。
我已经搜索了几天,我找到的任何解决方案都对我有效

我的HelloWebservlet。Amit K Bist回复后的xml

<property name = "suffix" value = ".jsp" />

</beans>
我出错了
Multiple annotations found at this line:
- cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'mvc:annotation-driven'.
- schema_reference.4: Failed to read schema document 'springframework.org/schema/mvc/spring-mvc.xsd', because 1) could not find the document;
2) the document could not be read; 3) the root element of the document is not <xsd:schema>.
第12行
<mvc:annotation-driven />
