我正在尝试从我的REST Web服务请求中获取请求参数。 @Path能够映射该方法。但是QueryParam无法从查询参数中获取值。

AccountIdexchsym不是查询参数,而是路径参数,而不是@QueryParam使用@PathParam

不要使用QueryParam for AccountId,exch和sym,而应使用@PathParam。

在JAX-RS中,您可以使用 @PathParem 将@Path表达式中定义的URI参数值注入Java方法。

/用户/查询?名称=斯鲁汀 在上面的URI模式中,查询参数是" nanme = Nasruddin",您可以使用 @QueryParam (" url")
