如何获取记录，计数总和应该在限制内。在下面的示例中，Records对象包含 recordId 和计数，我想根据计数的总和应该小于或等于我的限制条件来获取记录数据。

public class Records {
    private int recordID;
    private int count;

    public Records(int recordID, int count) {
        this.recordID = recordID;
        this.count = count;
    }

    public int getRecordID() {
        return recordID;
    }

    public void setRecordID(int recordID) {
        this.recordID = recordID;
    }

    public int getCount() {
        return count;
    }

    public void setCount(int count) {
        this.count = count;
    }
}


public static void main(String[] args) {
    
    final List<Records> recordList = new ArrayList<>();
    
    recordList.add(new Records(100, 10));
    recordList.add(new Records(501, 20));
    recordList.add(new …

我在请求中有以下HTTP标头,我想从中提取JSESSIONID它:

Accept=application/json
Accept-Encoding=gzip
deflate,Accept-Language=en-us
Connection=keep-alive
Content-Length=0
Content-Type=application/json
Cookie=JSESSIONID=ss0ox8w99o9142b73rssvc0r
Host=localhost:8080
User-Agent=NFA_QA/34 CFNetwork/720.5.7 Darwin/14.5.0 (x86_64)

我使用ContainerRequestContext如下:

@Override
public void filter(final ContainerRequestContext requestContext) throws IOException {
    System.out.println("***HEADER VALUE**: " + requestContext.getHeaderString("Cookie"));
}

获得结果:

JSESSIONID=zv71od6l2fd41hv6yf0980khy

和:

@Override
public void filter(final ContainerRequestContext requestContext) throws IOException {
    Map<String, javax.ws.rs.core.Cookie> clientCookie = requestContext.getCookies();
    System.out.println("Client Cookie Map: " + clientCookie);
}

获得结果:

Clinet Cookie Map: {JSESSIONID=JSESSIONID=1of1x5u1s1l4hdxfg2azlep42}

JSESSIONID从请求中提取的最佳方法是什么？
