[Jpa框架] jpa的:Running hbm2ddl schema update和 jpa打印sql语句，还有在项目里面配置linux 的日志存储路径

**validate**  加载hibernate时，验证创建数据库表结构  
**create**  每次加载hibernate，重新创建数据库表结构  
**create-drop**  加载hibernate时创建，退出是删除表结构  
**update**  加载hibernate自动更新数据库结构

**配置文件里注释掉即可**

这个是jpa 打印sql 值 和参数的， 要对应上面的show-sql 为true

===========================================

**@PostConstruct我一般使用来 测试定时任务的 时候启用**

@PostConstruct该注解被用来修饰一个非静态的void（）方法。被@PostConstruct修饰的方法会在服务器加载Servlet的时候运行: bean创建完成空对象，就开始进行@Autowire、@PostConstruct赋值
