浏览器跨越问题Access-Control-Allow-Origin Access-Control-Allow-Headers 属性设置

public class MobileDeviceTypeDetectionFilter implements Filter {
// 自定义过滤器
    @Override
    public void destroy() {

    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        final HttpServletRequest httpRequest = (HttpServletRequest) request;
        final HttpServletResponse httpResponse = (HttpServletResponse) response;

        httpResponse.setHeader("Access-Control-Allow-Origin", "*"); // 请求域名
        httpResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");// 请求方法
        httpResponse.setHeader("Access-Control-Max-Age", "3600");
        httpResponse.setHeader("Access-Control-Allow-Headers", "*"); // 允许的请求头
　　　　// 浏览器默认会发起异常 OPTIONS 的请求方式 这个时候我们通过过滤器直接拦截返回200后就可以解决跨越问题
        if ("OPTIONS" == (httpRequest.getMethod())) {
            httpResponse.setStatus(HttpServletResponse.SC_OK);

        }
        chain.doFilter(httpRequest, httpResponse);
    }

    @Override
    public void init(FilterConfig arg0) throws ServletException {

    }

}
