获取从前台传过来的参数，并放置到相应的类中

用法：
AppSysListVo appSysListVo = setParam(req.getParameterMap(), AppSysListVo.class);

public static 
 
   T setParam(Map
   paramMap, Class
  
    t){ try { T pojo = t.newInstance(); //遍历类中的变量 for (Field field : t.getDeclaredFields()) { String[] value = (String[])paramMap.get(field.getName()); if(isNotEmpty(value)){ try { field.setAccessible(true); if(field.getType().isAssignableFrom(String.class)) field.set(pojo, value[0].trim()); else if(field.getType().isAssignableFrom(Integer.class)) field.set(pojo, Integer.valueOf(value[0])); } catch (Exception e) { e.printStackTrace(); continue; } } } return pojo; } catch (Exception e) { e.printStackTrace(); return null; } }
