我正在开发一个模块,我在其中使用休息服务来获取数据。我没有得到如何使用杰克逊存储 JSON 并存储它也有 Queryparam。任何帮助都非常感谢,因为我是新手。我正在尝试在 extjs 无限网格中进行服务器端过滤,该网格将以下请求发送到休息服务。
当页面第一次加载时,它会发送:
http://myhost/mycontext/rest/populateGrid?_dc=9999999999999&page=1&start=0&limit=500
当您在名称和地点上选择过滤器时,它会发送:
http://myhost/mycontext/rest/populateGrid?_dc=9999999999999&filter=[{"type":"string","value":"Tom","field":"name"},{"type":"string","value":"London","field":"Location"}]&page=1&start=0&limit=500
我正在尝试将其保存在 POJO 中,然后将其发送到数据库以检索数据。在休息方面,我写了这样的东西:
@Provider
@Path("/rest")
public interface restAccessPoint {
@GET
@Path("/populateGrid")
@Produces({MediaType.APPLICATION_JSON})
public Response getallGridData(FilterJsonToJava filterparam,@QueryParam("page") String page,@QueryParam("start") String start,@QueryParam("limit") String limit);
}
public class FilterJsonToJava {
@JsonProperty(value ="filter")
private List<Filter> data;
.. getter and setter below
}
public class Filter {
@JsonProperty("type")
private String type;
@JsonProperty("value")
private String value;
@JsonProperty("field")
private String field;
...getter and setters below
}
我收到以下错误:
