Spring级联字段未更新

Question

我有一个具有以下属性的对象，但是当我尝试保存该对象时，此字段未合并。 我该如何解决这个问题？

@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

而不是保存属性：

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

我加入该网站更新每个用户的网站清单，登记到关注领域：

@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;
