在网上找了很多的内容，都没法解决，最后通过https://blog.csdn.net/wild46cat/article/details/52456715中内容解决的，在此记录一下。

HelloWorldController内容：

public String hello(Model model) {
model.addAttribute("greeting", "Hello Spring MVC");
return"helloworld";
} @RequestMapping("/heihei")
public String heihei(){
return "redirect:/html/final.html";
}
}

helloworld.jsp内容（最后是通过添加${pageContext.request.contextPath}解决访问问题，其他的配置网上基本千篇一律）：

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>

</head>
<body>
<div style="margin-bottom: 10px;"><img alt="" src="${pageContext.request.contextPath}/images/43.png"></div>
<h1 class="a">${greeting}</h1>
<form action="/HelloSpringMVC/heihei">
<input type="submit" value="获取页面">
</form>
</body>
</html>

final.html内容：

<!DOCTYPE html>
