Hibernate @OneToMany等注解设置查询过滤条件等

1、如实体PdOrg对象中有users对象，数据库user表有字段DEL_FLAG(0：删除；1：未删除)：

private List<User> users= new ArrayList<User>();

生成get、set方法：

@OneToMany(fetch=FetchType.LAZY, mappedBy="user")

@BatchSize(size=10)

@Where(clause="DEL_FLAG=1")

@OrderBy(clause="CREATED_DATE asc")

public List<User> getUsers() {

　　return this.user;

}

public void setUsers(List<User> user) {

　　this.user= user;

}

@BatchSize(size=10) //缓存数据大小：10条数据

@Where(clause="DEL_FLAG=1") //代表只取未删除的数据；

@OrderBy(clause="CREATED_DATE asc") //代表按创建时间正序排列

2、用一个列关联多个实体属性，比如举报维权，举报的对象可能是用户，悬赏，商品，订单

//举报对象(用户)

@OneToOne(cascade = { CascadeType. REFRESH }, fetch = FetchType.EAGER )

@JoinColumn(name = "gid", insertable = false, updatable = false)

@NotFound(action=NotFoundAction. IGNORE)

private UserInfo reporteder;

//举报对象(悬赏)

@OneToOne(cascade = { CascadeType. REFRESH }, fetch = FetchType.EAGER )

@JoinColumn(name = "gid", insertable = false, updatable = false)

@NotFound(action=NotFoundAction. IGNORE)

private Reward reward;

//举报对象(商品)

@OneToOne(cascade = { CascadeType. REFRESH }, fetch = FetchType.EAGER )

@JoinColumn(name = "gid", insertable = false, updatable = false)

@NotFound(action=NotFoundAction. IGNORE)

private Product product;

//举报对象(订单)

@OneToOne(cascade = { CascadeType. REFRESH }, fetch = FetchType.EAGER )

@JoinColumn(name = "gid", insertable = false, updatable = false)

@NotFound(action=NotFoundAction. IGNORE)

private Order order;
