Hibernate

@Lob 通常与@Basic同时使用，提高访问速度。 
@Lob 
@Basic(fetch = FetchType.LAZY) 
@Column(name="DtaContent", columnDefinition="CLOB", nullable=true) 
 public String getDtaContent() {
    return dtaContent;
  }

@Basic  实体Bean中所有的非Static 非transient的属性都可以被持久化,没有定义注解属性的等价于在其上添加了@Basic注解 
通过@Basic注解可以声明属性的获取策略(lazy与否),默认的是即时获取(early fetch),这里又讨论到了 
延迟关联获取和延迟属性获取,通常不需要对简单属性设置延迟获取,如需要定义@Basic(fetch=FetchType.LAZY)
