Spring MVC + Zepto POST中的“ Access-Control-Allow-Origin”错误

我找到了解决方案：

首先，创建一个新的过滤器，该过滤器将设置标头响应：

    @Componentpublic class SimpleCORSFilter implements Filter {    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {        HttpServletResponse response = (HttpServletResponse) res;        response.setHeader("Access-Control-Allow-Origin", "*");        response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");        response.setHeader("Access-Control-Max-Age", "3600");        response.setHeader("Access-Control-Allow-Headers", "x-requested-with");        chain.doFilter(req, res);    }    public void init(FilterConfig filterConfig) {}    public void destroy() {}}

之后，在您的web.xml中添加以下行：

 <filter>  <filter-name>cors</filter-name>  <filter-class>MY.PACKAGE.SimpleCORSFilter</filter-class> </filter> <filter-mapping>  <filter-name>cors</filter-name>  <url-pattern>/*</url-pattern> </filter-mapping>

而这一切！
