SpringBoot2.X开启跨域配置 - 超级大汇总——DBC的博客超级大汇总—

搞一个拦截类——CorsInterceptor

public class CorsInterceptor implements HandlerInterceptor {
    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        //表示接受任意域名的请求,也可以指定域名
        response.setHeader("Access-Control-Allow-Origin", request.getHeader("origin"));

        //该字段可选，是个布尔值，表示是否可以携带cookie
        response.setHeader("Access-Control-Allow-Credentials", "true");

        response.setHeader("Access-Control-Allow-Methods", "GET, HEAD, POST, PUT, PATCH, DELETE, OPTIONS");

        response.setHeader("Access-Control-Allow-Headers", "*");
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {

    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {

    }
}

最后在配置拦截类里面加入以下代码

    public CorsInterceptor getCorsInterceptor(){
        return new CorsInterceptor();
    }

  /**
         * 拦截全部路径  需要放在最上面
         */
        registry.addInterceptor(getCorsInterceptor()).addPathPatterns("/**");
