WebUtils複用代碼【request2Bean、UUID】

request封裝到Bean對象

public static <T> T request2Bean(HttpServletRequest httpServletRequest, Class<T> aClass) {


        try {
            //對於日期而言，是須要日期轉換器的
            ConvertUtils.register(new DateLocaleConverter(), Date.class);

            //獲取Bean的對象
            T bean = aClass.newInstance();

            httpServletRequest.setCharacterEncoding("UTF-8");

            //獲取表單中全部的名字
            Enumeration enumeration = httpServletRequest.getParameterNames();

            //遍歷表單提交過來的名字
            while (enumeration.hasMoreElements()) {

                //每一個名字
                String name = (String) enumeration.nextElement();

                //獲取獲得值
                String value = httpServletRequest.getParameter(name);

                //若是用戶提交的數據不爲空，那麼將數據封裝到Bean中
                if (!value.equals("") && value != null) {
                    BeanUtils.setProperty(bean, name, value);
                }
            }
            return bean;
        } catch (Exception e) {
            e.printStackTrace();
            throw new RuntimeException("封裝數據到Bean中，失敗了！");
        }
    }

UUID工具方法

public static String makeId() {
        return UUID.randomUUID().toString();
    }
