响应头设置跨域和Spring注解跨域

CORS跨域原理详解
Spring解决跨域

1. 响应头设置跨域

    @RequestMapping(value = "/ajax")
    public @ResponseBody
    Customer ajax(Integer id, HttpServletResponse response) {
        Customer customer = customerService.queryCustomerById(id);
        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,Authorization");
        response.setHeader("Access-Control-Allow-Credentials", "true");
        return customer;
    }

2. Spring注解跨域
   @CrossOrigin 可添加到方法上，也可添加到类上

    // orgins=''http://localhost:63343"表示允许域名为
 http://localhost:63343 访问该方法
  // origins="*", 表示允许所有其他的网站访问该方法
    @CrossOrigin(origins = "http://localhost:63343")
    @RequestMapping(value = "/ajax")
    public @ResponseBody
    Customer ajax(Integer id, HttpServletResponse response) {
        Customer customer = customerService.queryCustomerById(id);
        return customer;
    }
