Configuration cfg = new Configuration();
cfg.configure(); // 預設讀取 hibernate.cfg.xml
SchemaExport export = new SchemaExport(cfg);
export.setOutputFile("src/main/database/all.sql");
export.setDelimiter(";");
export.setFormat(true);
export.create(true, false);
但這種作法有一個前提，就是要有 hibernate.cfg.xml，可是隨著 Spring 的不斷滲透，hibernate.cfg.xml 慢慢的已經不見了，其設定值都進到 Spring XML 設定檔裡了。
public interface UserDao {
User get(int uid);
User getByAccount(String account);
void add(User cmd);
void update(User cmd);
void delete(User cmd);
List<User> list(UserQueryVO queryVO, int start, int pageSize);
int count(UserQueryVO queryVO);
}
@Scheduled(fixedRate = 10000) @Scheduled(fixedDelay = 5000) @Scheduled(cron = "*/3 50-55 9,10 26 * ?")這有什麼問題呢？問題發生在「參數化」。

@Scheduled 與 @Async 的用法同 Schedule in Spring 3.1.2。Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/context] Offending resource: class path resource [spring-app.xml]說是找不到 NamespaceHandler，這是什麼鬼東西啊。
