JAX-RS Path with count regular expression

Question

If I use the "{}" to specify the count condition in the regular expression of JAX-RS @Path, eclipse throws as error.

@Path("/apps/{itemId:\\d{10}}")
public Response getItems(...

The @Path annotation value '/apps/{itemId:\d{10}}' is invalid: missing '{' or '}'.

Is above JAX-RS Path not a valid path ? Is it due to eclipse JAX-RS validator problem ? If I just specify @Path("/apps/{itemId}") there is no error.

using regex in Path annotation时，不能在变量内使用大括号。改用：

@Path("/apps/{itemId: \\d+}")

  

regex = *（nonbrace /“ {” * nonbrace“}”）;其中nonbrace是除“ {”和“}”以外的任何字符

理论上，您可以使用多个[0-9]来检查10位数字：

@Path("/apps/{itemId: [0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]}")
