Hibernate双向多对多 注解方式

Function类

//多对多关系
@ManyToMany(mappedBy="functions",cascade=CascadeType.ALL)
private Set<Role> roles = new HashSet<Role>();

Role类

//多对多关系
@ManyToMany(cascade=CascadeType.ALL)
@JoinTable(
            name="Fun_Role",
            joinColumns = @JoinColumn(name="Role_Id"),
            inverseJoinColumns = @JoinColumn(name="Fun_Id")
        )
private Set<Function> functions = new HashSet<Function>();

OK
