guava strings Strings.isNullOrEmpty(processStr)
Introspector.decapitalize : Thus "FooBah" becomes "fooBah" and "X" becomes "x", but "URL" stays as "URL".
CollectionUtils.isEmpty(list); list为NULL也可以用

4 xStream转换xml 和 json
XStream xstream = new XStream(new DomDriver());
xstream.alias("file", FileConfig.class);

7 web工程out输出
private static final void out(String string, HttpServletResponse response) {
PrintWriter writer = null;
try {
response.setContentType("application/json; charset=UTF-8");
response.setCharacterEncoding("UTF-8");
response.setHeader("progma", "no-cache");

dataJson.put("status", "201");
out.print(dataJson);
} finally {
if (null != writer) {
writer.flush();

8 json to map
public static Map<String, Object> jsonToMap(String paramJson ){ Map<String, Object> paramsMap = new HashMap<String, Object>(); paramsMap = (Map<String, Object>) JSONObject.fromObject(paramJson); return paramsMap; }
9 str 判null或者""或者0
/** * 判断obj是否为空或者0 是返True * @param obj * @return */ private static Boolean isNullOrZero(Object obj) { Boolean flag = false; if(null !=obj){ String str = String.valueOf(obj); if (("0").equals(str) || "".equals(str)) { flag = true; } }else{ flag = true; } return flag; }
