我正在尝试编写一个 Java 程序,该程序从 Polarion 获取工作记录信息并将其写入 DAT 文件以供以后使用。
我已经成功连接到我们的服务器并检索了WorkItem
对象,但是 getter 方法(除了getUri()
)似乎都不起作用,这造成了一个问题,因为我需要使用WorkItem
类的getWorkRecords()
方法来满足项目的要求。
我已经在我们的主 Polarion 服务器和我们的“登台”服务器上尝试了该类的所有 getter 方法,我们将其用作一种测试区域,用于测试我正在尝试编写的程序之类的东西,并且我已经完成了权限。
无论权限如何,我只查询我创建并分配给自己的一些虚拟工作项,因此不应该有任何权限问题,因为我只是试图查看我自己的工作项。
这是程序的代码:
package test;

public void printWorkRecords(){
for(int temp = 0; temp < workItems.length; temp++){
System.out.println(workItems[temp].getUri().toString());
}
}
public void writeDATFile() throws IOException{
ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream("C:\\Users\\sweidenkopf\\workspace\\test\\filename.dat"));

out.writeObject(workRecords);
} finally {
// Make sure to close the file when done

}

public void initializeFields() throws MalformedURLException, ServiceException, RemoteException{
factory = new WebServiceFactory("//insert url here");
trackerService = factory.getTrackerService();
sessionService = factory.getSessionService();
sessionService.logIn("sweidenkopf", password);
workRecords = new ArrayList<>();
}
public void getWorkItems()throws MalformedURLException, ServiceException, RemoteException{
sessionService.beginTransaction();
workItems = trackerService.queryWorkItems("workRecords.user.id:sweidenkopf", null, null);
sessionService.endTransaction(false);
}
public void getWorkRecords()throws MalformedURLException, ServiceException, RemoteException{
sessionService.beginTransaction();
for(int k = 0; k < workItems.length; k++)
{System.out.println("This is working");
try{//not every work item has work records
System.out.println(workItems[k].getWorkRecords());
WorkRecord[] temp;
temp = workItems[k].getWorkRecords();
for(int x = 0; x < temp.length; x++){
System.out.println("This is working fine");
workRecords.add(temp[x]);
}
}catch(NullPointerException e){
System.out.println("I must regretfully inform you that I have grave news; your endeavors have not been successfull.");
continue;
}
}
System.out.println(workRecords.toString());
sessionService.endTransaction(false);
}
public void readDATFile() throws FileNotFoundException, IOException, ClassNotFoundException{
ObjectInputStream in = new ObjectInputStream(new FileInputStream("C:\\Users\\sweidenkopf\\workspace\\test\\filename.dat"));
try{
Object temp = in.readObject();
workRecords = (ArrayList) temp;
}
finally{
in.close();
}
}
}
最重要的部分当然是我的代码getWorkRecords()
中的方法。如您所见,它包含我用于调试目的的语句。该语句返回,并且在该语句中替换时唯一不返回 null 的方法是。此外,该方法中的 try-catch 块总是捕获 a因为循环 contains , temp 是一个应该包含方法返回的变量。System.out.println(workItems[k].getWorkRecords());
null
WorkItem
getUri()
NullPointerException
for
temp.length
getWorkRecords()
总结这里的主要问题是我无法getWorkRecords()
从类中返回任何内容或任何其他 getter 方法WorkItem
。这令人费解,因为该getUri()
方法执行成功,因为printWorkRecords()
我的代码中的方法成功打印了WorkItem
我的查询中所有对象的 URI。
有没有遇到过这个问题的 Polarion 专家?有谁知道我做错了什么?我倾向于认为这是一个基于情况的错误。
