主要是把引數object中例如name和返回objct中那麼屬性值進行克隆並返回selectObject物件

/**更改查詢的po的分頁條數資訊*/
public static <T> T copyAttr(Object parameter,Object  selectObj) {
    Field [] fields = parameter.getClass().getDeclaredFields();
    if(null!=fields){
        for(int i=0;i<fields.length;i++){
            Field pojo = fields[i];
 
String attrName = pojo.getName();
Object attrValue = null;
Field rfield;
            try {
                pojo.setAccessible(true);
attrValue = pojo.get(parameter);
rfield = selectObj.getClass().getField(attrName);
rfield.setAccessible(true);
rfield.set(selectObj,  attrValue);
