无法将JSON映射到Java bean

我收到错误：

线程“main”中的异常org.springframework.http.converter.httpMessageNotReadableException：无法读取JSON：无法从START_ARRAY令牌中反序列化com.zee.FilterVO的实例.在[来源：sun.net.www.protocol.http.httpURLConnection$httpinputStream@1b54362; line：1,column：1];嵌套异常是org.codehaus.jackson.map.JsonMapPingException ::无法从START_ARRAY令牌中反序列化com.zee.FilterVO的实例

Java调用获取JsON：

ResponseEntity

用于映射JsON的Java Bean：

public class FilterVO {    private String username;    private String expirationTime;    private String lastMatchedTime;    private String state;    private Integer matchedTodayCount;    private Boolean useRegEx;    private List

JsON我想要得到的：

[{    "username": "Z111111","expirationTime": "2015-03-15T14:00:00.000-0400","activationTime": "1969-12-31T19:00:00.000-0500","hosts": ["aa","bb"],"matchStrings": [" aa is not running"," bb is not running"],"useRegEx": false,"nameValuePairs": {        "KEY VALUE": "asasa","PROGRAM": "dsds","REGION": "dfsffs"    },"objectID": "SOMEID:20141015140803579-802","matchedTodayCount": 190,"lastMatchedTime": "2015-03-09T07:53:20.366-0400","state": "ACTIVE","description": "Blah Blah Blah..."}]

Initially I thought I am facing this issue because of deserialization of one element Array. So I modifIEd my java code.

private voID getFilter() {        RestTemplate restTemplate = getCustomrestTemplate();        httpheaders headers = new httpheaders();        headers.setAccept(Arrays.asList(MediaType.APPliCATION_JsON));        headers.set("access-token",getAccesstoken());        httpentity

我仍然得到同样的错误.

我在我的类路径中有以下杰克逊罐子：

jackson-annotations-2.5.1.jarjackson-core-2.5.1.jarjackson-core-asl-1.9.13.jarjackson-databind-2.5.1.jarjackson-datatype-joda-2.5.1.jarjackson-mapper-asl-1.9.13.jar
