java - 在 StringTokenizer 中有条件地添加字符串

Question

我目前在使用 StringTokenizer 时遇到了一个非常简单但令人困惑的问题。我想要实现的目标如下:

我的 URL 字符串为:

http://xxx:port/jira/rest/api/2/search?jql=project='TP' AND
(status='Ready for INT Deployment' or status = 'Ready for UAT Deployment')

以上是基本字符串。现在我想向上面的 URL 动态添加更多查询参数，如下所示:

"AND (key=NN-1234 OR key=NN-4321 OR key=NN-65343.....)"

这是我的代码:

private String getPartialIssueList() {
    String listFromProperties = getPropertyValue("propagateList");
    StringTokenizer token = new StringTokenizer(listFromProperties, ",");
    StringBuilder partialListString = new StringBuilder();
    partialListString.append(" AND key=");

    while (token.hasMoreElements()) {
        partialListString.append(token.nextElement() + " OR key=" + token.nextElement());
    }
    return partialListString.toString();
}

不知何故，这只在我有 2 个输入时才有效。我想要的是，在基本 url 之后应添加一个“AND”，后跟左括号“(”，然后是 key="属性中的值"，属性中的值 2，属性中的值 3，然后是右大括号“)”。无论属性文件中有多少个 JIRA ID，它都应该继续添加“OR key=NN-5432 OR key="NN-9875”等。

这是我正在寻找的输出:

http://xxx:port/jira/rest/api/2/search?jql=project='TP' AND 
(status='Ready for INT Deployment' or status = 'Ready for UAT Deployment') AND 
(key=NN-09876 OR key=NN-09873 OR key=NN-09376 OR key=NN-02876)

属性文件中的propagateList的当前值为

propagateList="NN-09876","NN-65432","NN-65430"

有人可以帮忙吗？

需要单独准备关键条件。

private String getPartialIssueList() {
    String listFromProperties = getPropertyValue("propagateList");
    StringTokenizer token = new StringTokenizer(listFromProperties, ",");
    StringBuilder partialListString = new StringBuilder();
    partialListString.append(" AND ");
    partialListString.append("(");

    // Prepare key condition
    StringBuilder orKeys = new StringBuilder();
    while(token.hasMoreElements()) {
        // Replace token.nextToken() to token.nextToken().replaceAll("\"", "") if you don't want quotes
        orKeys.append("key=" + token.nextToken() + " OR ");
    }
    // Remove last "OR" and concatenate 
    partialListString.append(orKeys.toString().replaceAll(" OR $", ""));
    partialListString.append(")");

    return partialListString.toString();
}

结果:

System.out.println(getPartialIssueList());
AND (key="NN-09876" OR key="NN-65432" OR key="NN-65430")

现在，将基本 URL 连接到动态查询:

String base = "http://xxx:port/jira/rest/api/2/search?jql=project='TP' AND (status='Ready for INT Deployment' or status = 'Ready for UAT Deployment')";
base += getPartialIssueList();
System.out.println(base);
------------------------------------------
http://xxx:port/jira/rest/api/2/search?jql=project='TP' AND 
(status='Ready for INT Deployment' or status = 'Ready for UAT Deployment') AND 
(key="NN-09876" OR key="NN-65432" OR key="NN-65430")
