Hibernate in 出现的问题
今天项目中遇到hibernate in查询结果集为空的问题.

Object [] objects = temp.keySet().toArray();StringBuffer ids = new StringBuffer();for (Object object : objects) {ids.append("'").append(object).append("'").append(',');}ids.deleteCharAt(ids.length() - 1);String searchModules = "select m from Module m where m.id in ("+ids.toString()+")";return find(searchModules);
