从静态map中取值添加进数组

public final static Map<String,Integer> WUHAN_AREAS = new LinkedHashMap<String,Integer>(); static { WUHAN_AREAS.put("北省", B_AREA_ID); WUHAN_AREAS.put("汉市", H_AREA_ID); WUHAN_AREAS.put("昌区", 04); WUHAN_AREAS.put("口区", 02); WUHAN_AREAS.put("阳区", 03); WUHAN_AREAS.put("山区", 05); WUHAN_AREAS.put("湖区", 06); WUHAN_AREAS.put("甸区", 07); WUHAN_AREAS.put("江区", 08); WUHAN_AREAS.put("黄区", 09); WUHAN_AREAS.put("新区", 10); WUHAN_AREAS.put("江区", 00); WUHAN_AREAS.put("汉区", 01); WUHAN_AREAS.put("南区", 11); WUHAN_AREAS.put("青区", 12); } //区的id数组 public final static Long[] HA_AREAS_ARY = new Long[HA_AREAS.size()]; static{ int i = 0; for(String key : HA_AREAS.keySet()){ HA_AREAS_ARY[i++] = Long.parseLong(HA_AREAS.get(key).toString()); } }

从项目编译后的src下取文件到java中

@Controller@RequestMapping("/opinion/risk")public class RiskController extends BaseController { @RequestMapping("loadInfo") public ModelAndView loadInfo(String beginDate,String endDate,Page page,int articleType,int sortType){ page.setPageSize(9); ModelAndView mav = new ModelAndView(); page = riskService.getRiskArticle(beginDate, endDate, sortType, articleType, page); List<NewsBean> newsList = page.getData(); StringUtil util = new StringUtil(); String path = RiskController.class.getResource("/").getPath(); String fileName=path + "config/opinionWord.txt"; List<String> wordlist =util.readFileByLines(fileName); for(NewsBean bean : newsList){ String title = bean.getTitle(); String fmtTitle =util.colorStrByOpinionWord(wordlist,title,"red"); bean.setTitle(fmtTitle); } mav.addObject("page", page); mav.setViewName(PATH_RISK + "articleInfo"); return mav; }}//StringUtil中的readFileByLines和colorStrByOpinionWord方法： /** * 读取工程中的text文件 * @param filePath * @return */ public List<String> readFileByLines(String filePath){ List <String> li = new ArrayList<String>(); File file = new File(filePath); BufferedReader br = null; try { br = new BufferedReader( new InputStreamReader( new FileInputStream(filePath),"UTF-8")); String tempString = null; while((tempString = br.readLine()) != null){ li.add(tempString); } br.close(); return li; } catch (FileNotFoundException e) { e.PRintStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally { if (br!= null) { try { br.close(); } catch (IOException e) { e.printStackTrace(); } } } return null; }/** * 给字符串中预警词加高亮背景 * @param srcStr：源字符串 * @param color：高亮颜色 * @return */ public String colorStrByOpinionWord(List<String> wordlist, String srcStr, String color){ if(wordlist != null){ for(String keyword:wordlist){ if(keyword != null && !"".equals(keyword)){ color = (color == null || "".equals(color)) ? "red" : color;//默认红色高亮 srcStr = srcStr.replaceAll(keyword, "<font color=/""+color+"/">" + keyword + "</font>"); } } return srcStr; } return null; }
