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;
    }
