Java Mongodb numberlong查询

Question

我正试图从mongoDB获取具体数据。我有5个字段，用户可以根据这些字段进行搜索。这是我的代码：

Map<Object, Object> fields = new HashMap<Object, Object>();
if (textField.getText().length() != 0)
    fields.put("FirstName", textField.getText());
if (textField_1.getText().length() != 0)
    fields.put("LastName", textField_1.getText());
if (textField_2.getText().length() != 0)
    fields.put("City", textField_2.getText());
if (textField_3.getText().length() != 0)
    fields.put("EmailAddress", textField_3.getText());
if (textField_4.getText().length() != 0)
    fields.put("PhoneNumber", "NumberLong(" + textField_4.getText() + ")");
query.putAll(fields);
long startTime = System.nanoTime();
DBCursor result = coll.find(query);
ArrayList<ArrayList<Object>> list = createListDataMongo(result); 

除电话号码外，所有搜索字段都有效。当我添加到查询电话号码时，什么都不会返回PhoneNumber是我的mongoDB数据库中的NumberLong字段。我怎么处理这个问题

Answer 1

fields.put("PhoneNumber", "NumberLong(" + textField_4.getText() + ")");

搜索PhoneNumber具有类型text（字符串）的值"NumberLong(" + textField_4.getText() + ")"的文档

请试试这个

fields.put("PhoneNumber", Long.parseLong(textField_4.getText()));

和往常一样，处理例外情况
