@RequiresPermissions("jyb:SLTransactions:view")
@RequestMapping(value = { "getReturnData" })
public void getReturnData(TrmPositionDetail trmPositionDetail,
HttpServletRequest request, HttpServletResponse response,
Model model) throws ParseException, IOException{

TrmPositionDetail trmPositionDetail1=new TrmPositionDetail();
trmPositionDetail1.setSymbol(trmPositionDetail.getSymbol());
trmPositionDetail1.setProductid(trmPositionDetail.getProductid());
trmPositionDetail1.setTradedate(trmPositionDetail.getTradedate());

List<TrmPositionDetail> dataList=new ArrayList<TrmPositionDetail>();
trmPositionDetail1.setDirection("01");
List<TrmPositionDetail> dataList1 = trmPositionDetailService.findList(trmPositionDetail1);
trmPositionDetail1.setDirection("02");
List<TrmPositionDetail> dataList2 = trmPositionDetailService.findList(trmPositionDetail1);
dataList.addAll(dataList1);
dataList.addAll(dataList2);
final String id=trmPositionDetail.getId();

Collection<TrmPositionDetail> filterData= Collections2.filter(dataList, new Predicate<TrmPositionDetail>() {
@Override
public boolean apply(TrmPositionDetail trmPositionDetail) {
boolean flag=false;
if (trmPositionDetail.getId().equals(id)){
flag=false;
}else{
flag=true;
}
return flag;

}
});

renderJsonString(response, filterData);

}

这是项目的一个方法，大家可以对应进行编写
