报错：org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: XX, could not initialize proxy - no Session(未能惰性地初始化角色集合:XX，无法初始化代理-没有会话)

解决方法：
将 @OneToMany(fetch = FetchType.LAZY, orphanRemoval = true, cascade = CascadeType.ALL)

改为 @OneToMany(fetch = FetchType.EAGER, orphanRemoval = true, cascade = CascadeType.ALL)
