我有@ManyToMany时如何设置ForeignKey名称

Question

我正在使用JPA类创建数据库.

如果我们有ManyToOne关系,我们可以像这样覆盖ForeignKey名称:

@ManyToOne
@JoinColumn(foreignKey = @ForeignKey(name = "FK_COUNTRY"))
private Country country;

在DB中,我们将得到这样的结果:

好的,那很好.好结果!

但是当我有@ManyToMany时,我将无法设置我自己的FK名称.

我该如何创建呢？我尝试这样的东西,但它不起作用:

@ManyToMany(cascade = CascadeType.PERSIST, fetch = FetchType.LAZY)
@JoinTable(name = "NEW_TABLE",  foreignKey = @ForeignKey(name = "FK_TEST"))

或类似的东西:

@JoinTable(
        name="NEW_TABLE",
        joinColumns=
            @JoinColumn(name="ID1", referencedColumnName="ID",  foreignKey = @ForeignKey(name = "FK_DEV_ID")),
        inverseJoinColumns=ID2", referencedColumnName="ID", foreignKey = @ForeignKey(name = "FK_DEV_ZONE"))
    )  

或这个:

@ManyToMany(cascade = CascadeType.PERSIST)
@JoinTable(name="NEW_TABLE_2",
            joinColumns=
                @JoinColumn(name="ID1", referencedColumnName="ID", 
                            foreignKey = @ForeignKey(name = "FK_1")
                ),
            inverseJoinColumns=
                @JoinColumn(name="ID2", referencedColumnName="ID", 
                            foreignKey = @ForeignKey(name = "FK_2")
                ),

            foreignKey = @ForeignKey(name = "FK_1"),
            inverseForeignKey = @ForeignKey(name = "FK_2")
    )  

private List<MyObject> deviceZones;

它们不起作用.

我使用这个版本的罐子:
