Spring boot 获取（失败）网络：：错误\u连接\u被拒绝

我试图在后端调用一个API，但我一直收到一个连接被拒绝的错误。后端位于部署在BlueHost中的tomcat服务器内；框架为spring boot；其war文件已部署在webapp文件夹中；我已经在web.xml中包含了以下过滤器，以允许CORS

<filter>
                <filter-name>CorsFilter</filter-name>
                <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
                <init-param>
                        <param-name>cors.allowed.orgins</param-name>
                        <param-value>*</param-value>
                </init-param>
                <init-param>
                        <param-name>cors.allowed.methods</param-name>
                        <param-value>GET,POST,HEAD,OPTIONS,PUT</param-value>
                </init-param>
                <init-param>
                        <param-name>cors.allowed.headers</param-name>
                        <param-value>Content-Type,X-Requested-With,accept,Origin,Access-Control-Request-Method,Access-Control-Request-Headers</param-value>
                </init-param>
                <init-param>
                        <param-name>cors.exposed.headers</param-name>
                        <param-value>Access-Control-Allow-Origin,Access-Control-Allow-Credentials</param-value>
                </init-param>
                <init-param>
                        <param-name>cors.support.credentials</param-name>
                        <param-value>true</param-value>
                </init-param>
        </filter>
        <filter-mapping>
                <filter-name>CorsFilter</filter-name>
                <url-pattern>/*</url-pattern>
        </filter-mapping>

我重新启动了apache和tomcat好几次，仍然一无所获。我也无法从Tomcat中看到任何有用的日志，并且我还确保该过程仍在使用netstat。我不知道该怎么办。如有任何建议，将不胜感激

谢谢

问题源于httpd.conf中错误配置的include文件和my pom.xml中错误配置的路径

let httpReq = {
        method: type,
        headers: {
            "Content-Type": "application/json",
            Accept: "application/json"
        },
        referrer: window.location.href, // https://web.dev/referrer-best-practices/
        referrerPolicy: "strict-origin-when-cross-origin",
        mode: "cors",
        credentials: "same-origin",
        cache: "default",
        redirect: "error"
    };


await fetch("http://localhost:8080" + api, httpReq)
        .then(response => {
            return response.json();
        })
