62 　　注意事项：
63 　　　　①构造方法的字段名、顺序、个数，要与查询语句的一致
64 　　　　②查询方法中要加入主键
65 　　　　③在实体类中要有无参的构造方法和有参数的构造方法
　　　　　　④如果代码中涉及到时间类型，注意时间类型的转换
　　　　　  ⑤　com.haiyisoft.entity.wz.WzInitializeStoreInfo实体类全路径

　　模糊查询：

　　　　if(param.get("wzName")!=null){

　　　　　　①jpql.append(" and c.wzName like "+"‘"+param.get("wzName").getValue()+"‘");

　　　　或者： ②jpql.append(" and c.wzName like ：wzName ‘‘);

　　　　}

　　　　　　　②List<Object> list=supplyDAO.find(jpql.toString(), param,sort,pageInfo);

　　　　注意   ①和②的差别，①如果传参数会报找不到相应字段的错误
