我已经在Spring Boot中实现了针对CORS的过滤器，代码如下：-

@SpringBootApplication
@Component
public class Application implements Filter {
public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
}

@Override
public void init(FilterConfig filterConfig) throws ServletException {

}

@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
    HttpServletRequest request = (HttpServletRequest) servletRequest;
    HttpServletResponse response = (HttpServletResponse) servletResponse;

    response.setHeader("Access-Control-Allow-Origin", "*");
    response.setHeader("Access-Control-Allow-Credentials", "true");
    response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
    response.setHeader("Access-Control-Max-Age", "3600");
    response.setHeader("Access-Control-Allow-Headers", "Content-Type, Accept, X-Requested-With, remember-me");

    filterChain.doFilter(servletRequest, servletResponse);
}

@Override
public void destroy() {

}
}

为了从oauth2获取access_token我已经从angularjs创建了以下对象：

 {"url":"http://localhost:8080/oauth/token?grant_type=client_credentials&client_id=clientId&client_secret=clientSecret","headers":{"Authorization":"Basic token_value"},"withCredentials":true,"method":"POST"}

我在服务器上遇到以下错误：-

OPTIONS url... 401() Response for preflight has invalid HTTP status code 401

我已经在堆栈溢出中寻找类似问题的解决方案，但都没有解决我的问题。有人可以帮忙吗？
