为什么两个Jerseyendpoint都被击中？

Question

当我转到<代码>/银行/1我看到了预期的账户信息。很好，很好。

当我转到<代码>/银行/1/description我看到了描述（好），但我也看到了帐户信息（不好）。

我习惯了Spring的GetMap，如果多个路径匹配，事情就会中断——但即便如此，AFAIK，在我的代码中，无论如何只有一个应该匹配？

银行。Java语言

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);
    }
}

帐户ction.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：

17-Jan-2020 11:54:57.526 INFO [http-nio-8080-exec-1] edu...Bank.getDescription - URL: bank/1/description
17-Jan-2020 11:54:58.139 INFO [http-nio-8080-exec-1] edu...AccountAction.getAccount - URL: bank/1/description

Answer 1

替换此代码

@路径（“/{id:$d$}”）

通过

@路径（"/{id：[0-9]*}"）
