我收到错误:Syntax error, insert ")" to complete Expression当我尝试这样做时:

public interface IConectorT extends Library {
HashMap<String, String> xx= new HashMap<>();
IConectorT INSTANCE = (IConectorT) Native.loadLibrary("Eloqua API", IConectorT.class, new 
HashMap{{
      put("DeleteCustomObjectRecord", "DeleteCustomObjectRecord@8");
      }});
}

这是为什么？我认为它是因为它不是JRE 1.7但改变到那并没有帮助.

我有XLSX这个日期在单元格：03-09-2014当我使用Apache POI读取XLSX细胞，它这样写道：41883.0。

这就是我这样做的方式：

while (cellIterator.hasNext()) {
                Cell cell = cellIterator.next();
                cell.setCellType(Cell.CELL_TYPE_STRING);
                System.out.print(cell.getStringCellValue() + ";");
            }

由于我已将所有单元格转换为 String 类型，因此我希望日期不会变形...

有什么解决办法吗？ 包含日期的单元格上的 apache poi DataFormatter 这是解决方案:)

我做了findInBackground查询以获取对象列表.之后,我从我得到的结果中创建自己的对象:

query.findInBackground(new FindCallback<ParseObject>() {
        public void done(final List<ParseObject> hangOutList, ParseException e) {
            if (e == null) {
                for (int i = 0; i < hangOutList.size(); i++) {
                    String objectID= hangOutList.get(i).getObjectId();
                    String city = hangOutList.get(i).getString("City");
                    String name = hangOutList.get(i).getString("Name");
                    String createdBy = 
                           hangOutList.get(i).getString("CreatedBy");
                    HangOut ho=new HangOut(objectID, name, city, createdBy);
                    hangOuts.add(ho);
                }

现在,当我点击其中一个时,我希望能够删除它.在文档中,他们说这样做:myObject.deleteInBackground();

但是,我没有,ParseObject所以我不能这样做.现在我试图做这样的事情:

private void deleteHangout() {
   ParseObject po=new ParseObject("HangOut");
    po.setObjectId(hangOut.getObjectID());
    po.deleteInBackground();
}

它不起作用.有没有办法如何通过ID创建Parse对象.还是其他任何想法？

执行后我得到的错误deleteHangout:

我正在构建一个Maven Web MVC应用程序,我使用的是java配置而不是XML.

但是我收到此错误,我无法找到解决方案.
