如何通過javadriver檢索文本框中的MongoDB數據？

Question

如何檢索MongDB數據並使用javadriver在文本框中加載？

我嘗試下面的代碼來顯示數據，但我想在文本框的數據：

BasicDBObject doc = new BasicDBObject(); 
doc.put("Name", v2); 
doc.put("SID", n4); 
doc.put("University", v4); 
DBCursor Cur = coll.find(doc); 
System.out.println(Cur);

下面的代碼片段顯示瞭如何當您遍歷結果中提取一個文件的各個字段的查詢。如果你願意，你可以把每個領域放在一個GUI的文本框中。

完整的代碼示例是在這裏：https://gist.github.com/3087822

private static void queryAndDisplayStudents(DBCollection students) 
{ 
    // Get all students (no query criteria). 
    DBCursor cursor = students.find(); 

    // Iterate over the students. 
    while (cursor.hasNext()) 
    { 
     // Display each student. 

     DBObject student = cursor.next(); 

     // Get the individual fields of the student document. 
     // These individual fields could, for example, 
     // be put in text fields of a GUI. 
     String name = (String) student.get("Name"); 
     Number sid = (Number) student.get("SID"); 
     String university = (String) student.get("University"); 

     // Given that we are not actually building a GUI, 
     // just display the fields on the command line. 
     System.out.printf("Student name: %s, SID: %d, University: %s%n", 
          name, sid, university); 
    }   
}
