[英]Jersey JAX-RS - matching regular expression
I have the following resources: 我有以下资源:
rounds resource 回合资源
@Path("/rounds")
public class RoundResource {
RoundService roundService = new RoundService();
@Path("{roundUri}/matches")
public MatchResource getMatchResource() {
return new MatchResource();
}
}
teams resource 团队资源
@Path("/teams")
public class TeamResource {
TeamService teamService = new TeamService();
@Path("/{teamUri}/matches")
public MatchResource getMatchResource() {
return new MatchResource();
}
}
matches resource 匹配资源
@Path("/matches")
public class MatchResource {
private MatchService matchService = new MatchService();
@GET
@Produces(MediaType.APPLICATION_JSON)
public List<Match> getTeamMatches(@PathParam("teamUri") String teamUri) {
return matchService.getTeamMatches(teamUri);
}
@GET
@Produces(MediaType.APPLICATION_JSON)
public List<Match> getRoundMatches(@PathParam("roundUri") String roundUri) {
return matchService.getRoundMatches(roundUri);
}
}
Where 哪里
/rounds/{roundUri}/matches
gets the matches of a round 获得一轮比赛
/teams/{teamUri}/matches
gets the matches of a team 获得球队的比赛
I got the matching regular expression error because the path in matches resource is /matches and both paths end with it. 由于匹配资源中的路径为/ matches并且两个路径均以其结尾,因此出现匹配的正则表达式错误。 How to solve it? 怎么解决呢?
The problem is in your matches resource . 问题出在您的比赛资源中。 The two methods map to same url i,e 这两种方法映射到相同的网址i,e
/matches So if you are not giving any @Path annotation to the methods then only one method should be there to avoid collision or give @Path annotation to either one of them or to both of them . / matches因此,如果您没有给方法提供任何@Path注释,则只有一种方法可以避免冲突,或者为其中一个或两个方法都提供@Path注释。 it will work 它会工作
I don't see why you have mentioned regular expression in your question . 我不明白您为什么在问题中提到正则表达式。 When the question you are asking is nothing related to regular expression . 当您要问的问题与正则表达式无关时。
Anyway to give pattern for path parameters you can add code like this 无论如何要给出路径参数的模式,您可以添加如下代码
@Path("method1/{parameter1: [a-zA-Z][a-zA-Z_0-9]*}") // this regular expression is for alphanumeric
you should have both @Path annotation on method and @PathParam annotation on argument to work properly 您应该在方法上同时使用@Path注释和在参数上使用@PathParam注释才能正常工作
you should code like this in your matches resource 您应该在您的匹配资源中编写这样的代码
@Path("{teamUri}")
and 和
@Path("/roundUri/{roundUri}")
on your methods to work 根据您的工作方式
this will work for urls like /matches/xxxdf
and /matches/roundUri/xalfo
这将适用于/matches/xxxdf
和/matches/roundUri/xalfo
change your code like this it will work 像这样更改您的代码,它将起作用
@Path("/matches")
public class MatchResource {
private MatchService matchService = new MatchService();
@GET
@Path("{teamUri}")
//or @Path("{teamUri:[a-zA-Z][a-zA-Z_0-9]*}") if you want to use regular expressions
@Produces(MediaType.APPLICATION_JSON)
public List<Match> getTeamMatches(@PathParam("teamUri") String teamUri) {
return matchService.getTeamMatches(teamUri);
}
@GET
@Path("roundUri/{roudUri}")
//or @Path("{roundUri:[a-zA-Z][a-zA-Z_0-9]*}") if you want to use regular expressions
@Produces(MediaType.APPLICATION_JSON)
public List<Match> getRoundMatches(@PathParam("roundUri") String roundUri) {
return matchService.getRoundMatches(roundUri);
}
}
The point here is your url for resources should not clash 重点是您的资源网址不应冲突
I added @Path(" OPTION ") annotation to the match resource methods to specify if I want the matches by round or by team: 我在比赛资源方法中添加了@Path(“ OPTION ”)批注,以指定我是否要按轮比赛或按队比赛:
rounds resource 回合资源
@Path("/rounds")
public class RoundResource {
RoundService roundService = new RoundService();
@Path("{roundUri}/matches")
public MatchResource getMatchResource() {
return new MatchResource();
}
}
teams resource 团队资源
@Path("/teams")
public class TeamResource {
TeamService teamService = new TeamService();
@Path("/{teamUri}/matches")
public MatchResource getMatchResource() {
return new MatchResource();
}
}
matches resource 匹配资源
@Path("/matches")
public class MatchResource {
private MatchService matchService = new MatchService();
@GET
@Path("/byteam")
@Produces(MediaType.APPLICATION_JSON)
public List<Match> getTeamMatches(@PathParam("teamUri") String teamUri) {
return matchService.getTeamMatches(teamUri);
}
@GET
@Path("/byround")
@Produces(MediaType.APPLICATION_JSON)
public List<Match> getRoundMatches(@PathParam("roundUri") String roundUri) {
return matchService.getRoundMatches(roundUri);
}
}
Now I have: 我现在有:
/rounds/{roundUri}/matches/byround
gets the matches of a round 获得一轮比赛
/teams/{teamUri}/matches/byteam
gets the matches of a team 获得球队的比赛
