I am having trouble deserializing a JSON object. The object contains a collection which is being deserialized as a Map, which is the default. I need it to deserialize as a Set. My code is as follows:
TaskDetail.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);
}
From the front-end, I submit the data from my form which is received by my controller in the following format:
{"name":"Clean Shelves","description":"Clean all shelves in the store","roleDetails":{"description":"A person that counts stock","id":1,"name":"Stock Counter","version":0}}
I need the roleDetails object to be deserialized as a HashSet. How can I use the JsonDeserializer to do this? I assume it is something like this in RoleDetail.java:
public static RoleDetail fromJsonToRoleDetail(String json) {
return new JSONDeserializer<RoleDetail>().use(null, RoleDetail.class).use("roleDetail.values", HashSet.class).deserialize(json);
}
Or do I also have to code something similare in TaskDetail.java?
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}]}
