Spring級聯字段未更新

Question

我有一個具有以下屬性的對象，但是當我嘗試保存該對象時，此字段未合併。 我該如何解決這個問題？

@ManyToMany(targetEntity = User.class, mappedBy = "userSites", fetch = FetchType.LAZY, cascade = CascadeType.ALL) 
@NotAudited 
private List<IUser> localIt; 

userSites：

@BatchSize(size = 20) 
@ManyToMany(cascade = { CascadeType.MERGE, CascadeType.PERSIST }, fetch = FetchType.LAZY,targetEntity=Site.class) 
@JoinTable(name = "USER_SITE", 
joinColumns = { @JoinColumn(name = USER_ID, nullable = false) }, 
inverseJoinColumns = { @JoinColumn(name = "SITE_ID", nullable = false) }) 
private Set<ISite> userSites; 

Answer 1

而不是保存屬性：

@ManyToMany(targetEntity = User.class, mappedBy = "userSites", fetch = FetchType.LAZY, cascade = CascadeType.ALL) 
@NotAudited 
private List<IUser> localIt; 

我加入該網站更新每個用戶的網站清單，登記到關注領域：

@BatchSize(size = 20) 
@ManyToMany(cascade = { CascadeType.MERGE, CascadeType.PERSIST }, fetch = FetchType.LAZY,targetEntity=Site.class) 
@JoinTable(name = "USER_SITE", 
joinColumns = { @JoinColumn(name = USER_ID, nullable = false) }, 
inverseJoinColumns = { @JoinColumn(name = "SITE_ID", nullable = false) }) 
private Set<ISite> userSites;
