错误分析：template might not exist or might not be accessible by any of the configured Template Resolvers ......

原因一

	/*controller*/
	
    @GetMapping("/")
    public String index(){
        log.warn("访问了首页...");
        return "index";
    }

    @GetMapping("login")
    public String login(){
        log.warn("访问了登录页面");
        return "/pub/login";
    }

说明：在idea中可以正常的访问，没有问题。当打长成jar时测试结果如下：

即：

首页可以正常访问
登录页访问异常：Exception processing template “/pub/login”: Error resolving template [/pub/login], template might not exist or might not be accessible by any of the configured Template Resolvers

解决方法：将return "/pub/login"; 改为return "pub/login"; 即可

原因2

    @GetMapping("about")
    public String about(){
        return "pub/about";
    }

<!--about.html-->

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <link  th:replace="~{/layout/resource.html::club-head}">
</head>
<body>
    <main class="cd-main-content">
        join us
    </main>
</body>
</html>

有上面的原因1可以推测：controller没有问题，，即container所映射的?>about.html可以被找到；当却报错，那么问题就很有可能出现在about.html中
根据报错描述可知 在解析about.html是报错。看细看一下就会发现一段报错描述：: Error resolving template [/layout/resource.html], template might not exist or might not be accessible by any of the configured Template Resolvers (template: "pub/about" - line 4, col 12) 以此可以推测about.html中的<link th:replace="~{/layout/resource.html::club-head}"> 导致的。注释掉它再打包测试就可以呢
