Hibernate annotation @NotFound

解决异常：

org.hibernate.ObjectNotFoundException: No row with the given identifier exists

原因：多对一映射时，一方表中对应的数据不存在才抛出的。

	@ManyToOne(fetch = FetchType.LAZY)
	@JoinColumn(name = "USER_ID", nullable = false, insertable = false, updatable = false)
	@NotFound(action = NotFoundAction.IGNORE)
	public DcUserInfo getDcUserInfo() {
		return this.dcUserInfo;
	}
