    copied!<p>I have a json </p> <pre> <code>[ { "host": { "name": "anotherfullhost", "id": 55602819, "operatingsystem_id": 1073012828, "hostgroup_id": null } }, { "host": { "name": "dhcp.mydomain.net", "id": 219245707, "operatingsystem_id": 1073012828, "hostgroup_id": null } }, { "host": { "name": "my5name.mydomain.net", "id": 980190962, "operatingsystem_id": 1073012828, "hostgroup_id": null } } ]</code> </pre> <p>I would like to construct a Collection by deserializing the above json. What jackson annotations should I add to the below Host class</p> <pre> <code> public class Host { @JsonProperty("id") private Long id; @JsonProperty("name") private String name; @JsonProperty("operatingsystem_id") private Long operatingSystemId; @JsonProperty("hostgroup_id") private Long hostGroupId; public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public Long getOperatingSystemId() { return operatingSystemId; } public void setOperatingSystemId(Long operatingSystemId) { this.operatingSystemId = operatingSystemId; } public Long getHostGroupId() { return hostGroupId; } public void setHostGroupId(Long hostGroupId) { this.hostGroupId = hostGroupId; } @Override public String toString() { return "Host{" + "name='" + name + '\'' + '}'; } } </code> </pre> <p>Any suggestions?</p> <p>Note - I am using jackson 2.x API.</p> <p>Thanks.</p> <p><strong>Update</strong> Adding a wrapper object does the trick. </p> <pre> <code> public class HostWrapper { @JsonProperty("host") private Host host; public Host getHost() { return host; } public void setHost(Host host) { this.host = host; } @Override public String toString() { return host.toString(); } } and the below code to deserialize ObjectMapper mapper = new ObjectMapper(); HostWrapper[] host = mapper.readValue(jsonString, HostWrapper[].class); </code> </pre>
