Jax-RS中的可选@PathParam [英] Optional @PathParam in Jax-RS
问题描述
我有一项服务,其中路径的最后部分是可选的,用户可以输入 / mypath / 和 / mypath / param1 / 。
I have a service where the last part of the path is optional, the user can both enter /mypath/ and /mypath/param1/.
我尝试使用正则表达式来过滤路径的最后部分:
I tried to use a regular expression to filter the last part of the path:
@Path (/ mypath {param1:(/ param1)?})
我正在使用RestEasy作为我的JAX-RS提供程序代码在Tomcat中按预期工作,但当我在JBoss中部署它时,当我不提交可选部分时,我得到405返回代码。
I'm using RestEasy as my JAX-RS provider and the code works as expected in Tomcat but when I deploy it in JBoss I get a 405 return code when I do not submit the optional part.
我在这里做错了什么或者这是不可能以便携的方式完成这个?
Am I doing something wrong here or it's not possible to accomplish this in a portable way?
推荐答案
问题是冒号之前缺少空格:
The problem was the lack of whitespace before the colon:
@Path("/mypath{param1: (/param1)?}")
应该是:
@Path("/mypath{param1 : (/param1)?}")
显然这是一个错误,因为规范使冒号周围的空格可选。我还发现我不是第一个被这个错误所困扰。
Apparently it's a bug, because the specification makes the whitespace around the colon optional. I also found that I'm not the first bitten by this bug.
