为什么两个泽西端点都被击中？

Question

当我转到.../bank/1时，我会看到一个帐户信息，就像预期的那样。 很好，很好。

[当我转到.../bank/1/description时，我看到说明（good），但是我也看到了帐户信息（[not好）。

我习惯于Spring的GetMapping，如果多个路径匹配，事情就会中断-但是即使那样，在我的代码中AFAIK，仅一个也应该匹配吗？

为什么同时触发AccountActions？

Bank.java

Path("/bank")
public class Bank {

    @Context
    UriInfo uriInfo;

    @Context
    Request request;

    // ... Other irrelevant constructors, methods, and attributes

    @GET
    @Path("{acct}")
    public AccountAction getAccount(@PathParam("acct") String id) {
        LOGGER.log(Level.INFO, "- URL: " + uriInfo.getPath());
        return new AccountAction(uriInfo, request, id, accounts);
    }

    @GET
    @Path("{acct}/description")
    public AccountAction getDescription(@PathParam("acct") String id) {
        LOGGER.log(Level.INFO, "- URL: " + uriInfo.getPath());
        return new AccountAction(uriInfo, request, id, accounts);
    }
}

AccountAction.java

public class AccountAction {

    @Context
    UriInfo uriInfo;

    @Context
    Request request;

    // ... Other irrelevant constructors, methods, and attributes

    public AccountAction(UriInfo uriInfo, Request request, String id, AccountStore accounts) {
        this.uriInfo = uriInfo;
        this.request = request;
        this.id = new Integer(id);
        this.accounts = accounts;
    }

    @GET
    @Path("/{id:\\d+}/description")
    @Produces(MediaType.TEXT_PLAIN)
    public String getDescription() {
        LOGGER.log(Level.INFO, "- URL: " + uriInfo.getPath());
        Account a = accounts.find(id);
        if (a == null) {
            throw new RuntimeException("No such account: " + id);
        }
        return a.getDescription();
    }

    @GET
    @Path("/{id:\\d+$}")
    @Produces(MediaType.APPLICATION_XML)
    public Account getAccount() {
        LOGGER.log(Level.INFO, "- URL: " + uriInfo.getPath());
        Account a = accounts.find(id);
        if (a == null) {
            throw new RuntimeException("No such account: " + id);
        }
        return a;
    }
}

日志输出：

替换此代码

@ Path（“ / {id：\ d + $}”）
