我在将javascript文件加载到JSP页面时遇到问题。 相反，css文件正常加载。
在我的* .jsp文件中，我在“标题”部分加载脚本：
<script type="text/javascript" src="js/resources.js" charset="utf-8"></script>
在index.jsp文件的顶部，我指定了字符集：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
还在头部：
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
WildFly（第11版）返回的错误是：
Exception handling request to /trust/js/resources.js: java.lang.IllegalArgumentException: Null charset name
“/trust/js/resources.js”是我自己的js文件，我试图加载。
每个* .js文件都会出现此错误

firefox浏览器返回每个js文件（在其开发人员工具包中）的错误，请参见下图： enter image description here
提前感谢所有答案！
答案 0 :(得分：0)
问题在于servlet负责过滤路径。
public static boolean isResourceRequest(String path){
// Images & CSS & JS
if(path.toLowerCase().contains("/img/") || path.contains("/css/") || path.contains("/js/") || path.contains("/upload/") || path.contains("/fonts/")){
return true;
}
return false;
}
我只是通过添加所需的文件类型来改变条件 软件架构师有一个功能。
