我在反序列化 JSON 对象时遇到问题。该对象包含一个被反序列化为 Map 的集合，这是默认设置。我需要它反序列化为一个集合。我的代码如下：

任务详细信息.java

@ManyToMany
private Set<RoleDetail> roleDetails = new HashSet<RoleDetail>();

public String toJson() {
    return new JSONSerializer().exclude("*.class").include("roleDetails").serialize(this);
}

RoleDetail.java

@ElementCollection
@Enumerated(EnumType.STRING)
private Set<RoleFunction> roleFunctions = new HashSet<RoleFunction>();

public String toJson() {
    return new JSONSerializer().exclude("*.class").include("roleFunctions").serialize(this);
}

从前端，我提交了我的控制器接收到的表单中的数据，格式如下：

{"name":"Clean Shelves","description":"Clean all shelves in the store","roleDetails":{"description":"A person that counts stock","id":1,"name":"Stock Counter","version":0}}

我需要将 roleDetails 对象反序列化为 HashSet。我怎样才能使用 JsonDeserializer 来做到这一点？我假设它在 RoleDetail.java 中是这样的：

public static RoleDetail fromJsonToRoleDetail(String json) {
    return new JSONDeserializer<RoleDetail>().use(null, RoleDetail.class).use("roleDetail.values", HashSet.class).deserialize(json);
}

或者我是否还必须在 TaskDetail.java 中编写类似的代码？

Your roleDetails should be an array of objects, not an object.

You should have something like that :

{"name":"Clean Shelves","description":"Clean all shelves in the store","roleDetails":[{"description":"A person that counts stock","id":1,"name":"Stock Counter","version":0}]}
