我使用的杰克逊库来解析成JSON对象并使用ormlite存储到sqlite的分贝相同的对象。 这里是我的模型类:
public class Site {
private String uniqueId;
private String name;
private ForeignCollection<ContactDetails> items;
@JsonProperty("contact_details")
public void setContactDetails(ForeignCollection<ContactDetails> contact_details) {
this.items = contact_details;
}
public List<ContactDetails> getContactDetails() {
return new ArrayList<ContactDetails>(items);
}
public String getUniqueId() {
return uniqueId;
}
@JsonProperty("unique_id")
public void setUniqueId(String uniqueId) {
this.uniqueId = uniqueId;
}
public String getName() {
return name;
}
@JsonProperty("name")
public void setName(String name) {
this.name = name;
}
}
而ContactDetails类是:
public class ContactDetails {
@JsonProperty("contact_detail_id")
int getContactDetailId;
@JsonProperty("cellphone_number")
String getCellphoneNumber;
@JsonProperty("email")
String getEmail;
@JsonProperty("name")
String getName;
}
我的JSON是:
{
"unique_id": "WDV000282",
"name": "2XL - Diverse werken - Zeebrugge",
"contact_details": [
{
"contact_detail_id": 20647,
"cellphone_number": "123456",
"email": "plabon@gmail.com",
"name": "plabon",
},
{
"contact_detail_id": 20648,
"cellphone_number": "",
"email": "modak@gmail.com",
"name": "test",
}
]
}
但是,当我执行readvalue:
Site test= objectMapper.readValue(json, Site.class);
我得到以下异常
org.codehaus.jackson.map.JsonMappingException: Can not find a deserializer for non-concrete Collection type [collection type; class com.j256.ormlite.dao.ForeignCollection, contains [simple type, class com.example.jacksonparsingtest.ContactDetails]]
我没有收到发生了什么事?plz帮助...
