计算同比和环比增长率

今天做的项目中，遇到一个计算同期环比和上期环比的计算并显示出来。这是用ssm框架

代码示例：

@RequiresPermissions("analysis:analysis:smartSearch")@RequestMapping(value = "/analysis/analysis/smartSearch")public String smartSearch(){Page<ElectronicTax> page = new Page<ElectronicTax>(request, response);//page.setPageSize( 25 );if ( POST ){if ( !"".equals(request.getParameter("pageSize")) ){el.setPage(page);}Map<String, ArrayList<Map<String, Object>>> dataList = new HashMap<String, ArrayList<Map<String,Object>>>();Map<String, List<String>> keyOne = new HashMap<String, List<String>>();String transverse=null, munehisa=null;List<Map<String, Object>> list = companyService.getElectronicTaxDao().getSmartSearch(el);for( Map<String, Object> m : list ){if ( m != null ){Iterator<Entry<String, Object>> itr = m.entrySet().iterator();while( itr.hasNext() ){Entry<String, Object> ety = itr.next();String key = ety.getKey();String value = ety.getValue().toString();if ( "amount".equals(key) || ("accounting".equals(key) && el.getIsTime() == null )) continue;if ( keyOne.get(key) == null ){if ( munehisa == null ){munehisa = key;}else{transverse = key;}keyOne.put(key, new ArrayList<String>());}if ( !keyOne.get(key).contains( value ) ){keyOne.get(key).add(value);}}}}//横向为空，则只选择了一个字段，那么横向TITLE为金额if ( transverse == null ){//transverse = "amount";keyOne.put(transverse, new ArrayList<String>());keyOne.get(transverse).add("金额");System.out.println(keyOne.get(transverse));}else{if ( keyOne.get(transverse).size() > keyOne.get(munehisa).size()){//纵横向互换String s = transverse;transverse = munehisa;munehisa = s;}model.addAttribute("transverse_param", getParam(transverse));}model.addAttribute("munehisa_param", getParam(munehisa));Double currentsAmounts = null;Double LastsAmounts = null;for( Map<String, Object> m : list ){if ( dataList.get( m.get(munehisa) ) == null ){ArrayList<Map<String, Object>> tmpList = new ArrayList<Map<String, Object>>();Map<String, Object> twelveMap = new HashMap<String, Object>();for( Map<String, Object> mm : list ){if ( m.get(munehisa).equals( mm.get(munehisa) ) ){if ( transverse == null ){twelveMap.put("金额", mm.get("amount"));}elsetwelveMap.put(mm.get(transverse).toString(), mm.get("amount"));}}for( String ym : keyOne.get(transverse) ){Map<String, Object> map = new HashMap<String, Object>();Double currentAmount;map.put(transverse, ym);if ( twelveMap.get(ym) == null ){currentAmount = 0.0;}else{currentAmount = Double.parseDouble( twelveMap.get(ym).toString() );}map.put("amount", currentAmount);//对比计算if ( el.getIdenticalCompare() != null ){// System.out.println(m.get(transverse).toString());// System.out.println(m.get(munehisa).toString());// System.out.println(munehisa);// Double amount = companyService.getLastYearCount(m.get(transverse).toString(), m.get(munehisa).toString(), munehisa);// double amount=20;Double amount = 30d;amount.toString();map.put("identical", currentAmount - amount);if ( amount > 0 ){ map.put("identicals", (currentAmount - amount)/amount);}else map.put("identicals", 100);}if ( el.getRingCompare() != null ){Double amount = companyService.getLastMonthCount(m.get(transverse).toString(), m.get(munehisa).toString(), munehisa);if ( amount > 0 ){ map.put("ring", (currentAmount - amount)/amount);}else map.put("ring", 100);}if ( el.getCumulativeCompare() != null ){Double currentAmounts = companyService.getCumulativeCompare(m.get(transverse).toString(), m.get(munehisa).toString(), munehisa, "current");Double LastAmounts = companyService.getCumulativeCompare(m.get(transverse).toString(), m.get(munehisa).toString(), munehisa, "");//所有行业同比增量if ( currentsAmounts == null ){currentsAmounts = companyService.getCumulativeCompare(m.get(transverse).toString(),"", munehisa, "current");LastsAmounts = companyService.getCumulativeCompare(m.get(transverse).toString(), "", munehisa, "");}map.put("cumulative", currentAmounts);map.put("cumulatives", currentAmounts-LastAmounts);//增量if ( LastAmounts > 0 ){map.put("cumulativess", (currentAmounts-LastAmounts)/LastAmounts);//增速 }else{map.put("cumulativess", 100);//增量 }if ( currentsAmounts > 0 || LastsAmounts > 0){map.put("cumulativesss", (currentAmounts-LastAmounts)/(currentsAmounts-LastsAmounts));//增速 }else{map.put("cumulativesss", 100);//增量 }}tmpList.add( map );}dataList.put(m.get(munehisa).toString(), tmpList);}}model.addAttribute("dataList", dataList);model.addAttribute("transverse", keyOne.get(transverse));}if ( !"".equals(request.getParameter("pageSize")) ){model.addAttribute("page", page);}model.addAttribute("yearMonthList", companyService.getYearMonth());return "addons/analysis/analysis/smartSearch";}
