自己较常用的hibernate注释配置

1. OneToMany（XXClass）

@OneToMany(cascade = { CascadeType.PERSIST, CascadeType.MERGE }, mappedBy = "xx")
    @Cascade(org.hibernate.annotations.CascadeType.SAVE_UPDATE)
    private Collection<YYClass> prizes = new ArrayList<YYClass>();

与之对应的 ManyToOne(YYClass)

@ManyToOne(cascade = { CascadeType.PERSIST, CascadeType.MERGE })
    @Cascade(org.hibernate.annotations.CascadeType.SAVE_UPDATE)
    @JoinColumn(name = "xx_id", nullable = false)
    private XXClass xx;

2.ManyToMany(XXClass)

@ManyToMany( cascade = { CascadeType.PERSIST, CascadeType.MERGE })
    @JoinTable(name = "table_yyyy", joinColumns = { @JoinColumn(name = "xxxx_id") }, inverseJoinColumns = { @JoinColumn(name = "yyyy_id") })

private Set<ElectronicCoupon> electronicCoupons;

与之对应的 ManyToMany(YYClass)

@ManyToMany(cascade = { CascadeType.PERSIST, CascadeType.MERGE })
    @JoinTable(name = "t_ded5_member_coupon", joinColumns = { @JoinColumn(name = "yyyy_id") }, inverseJoinColumns = { @JoinColumn(name = "xxxx_id") })

private Set<ElectronicCoupon> electronicCoupons;

3.Id

@Id
@GeneratedValue(generator = "hibernate-uuid")
private String id;

4.普通字段

@Basic
@Column(name = "remark", length = 255)
