利用SpringMVC解决vue跨域请求

public boolean preHandle(HttpServletRequest request, HttpServletResponse response, 
        Object handler) throws Exception { 
  response.setHeader("Access-Control-Allow-Origin", "*"); 
  response.setHeader("Access-Control-Allow-Methods", "*"); 
  response.setHeader("Access-Control-Max-Age", "3600"); 
  response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept"); 
  response.setHeader("Access-Control-Allow-Credentials","true"); //是否允许浏览器携带用户身份信息（cookie） 
  return true; 
 }
