如何通过javadriver检索文本框中的MongoDB数据？

Question

如何检索MongDB数据并使用javadriver在文本框中加载？

我尝试下面的代码来显示数据，但我想在文本框的数据：

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);

下面的代码片段显示了如何当您遍历结果中提取一个文件的各个字段的查询。如果你愿意，你可以把每个领域放在一个GUI的文本框中。

完整的代码示例是在这里：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); 
    }   
}
