SpringMVC后台实现跨域支持

对请求的跨域支持.使用拦截器实现.在自定义拦截器中添加以下代码就可以实现啦

    @Override    public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception {        //增加跨域支持        httpServletResponse.setHeader("Access-Control-Allow-Origin", "*");        httpServletResponse.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");        httpServletResponse.setHeader("Access-Control-Max-Age", "3600");        httpServletResponse.setHeader("Access-Control-Allow-Headers", "x-requested-with");        return true;    }
