Question

我已经使用Apache CXF尝试了rest webservice。我正在执行创建操作。我能够创建，在以json和xml格式返回响应时，我没有得到任何价值。我的服务和服务实现如下。服务类：

@Path("/location/")
@WebService
public interface LocationService {

    @WebMethod
    @POST
    @Path("location")
    @Produces({"application/xml","application/json"})
    @Descriptions({
        @Description(value = "stores a new location data", target = DocTarget.METHOD),
        @Description(value = "the newly created location data", target = DocTarget.RETURN)
    })
    public LocationData createLocation(@Valid LocationData locationData) throws DuplicateLocationException;

}

ServiceImplementation：

@Service("locationService")
public class LocationServiceEndpoint implements LocationService {

    @Override
    public LocationData createLocation(LocationData locationData) {

        setNewID(locationData);
        return locationData;
    }

    private void setNewID(LocationData locationData) {
        // setting the ID
        String id = UUID.randomUUID().toString();
        locationData.setId(id);

    }
}

BeanClass：

@XmlRootElement(name = "LocationData")
public class LocationData {

    private String id;
    @DateTimeFormat(pattern="yyyy-mm-dd")
    private Date date;
    @NotNull
    private String timezone;
    @NotNull
    @Size(max = 20, min = 5)
    private String location;

    public void setTimezone(String timezone) {
        this.timezone = timezone;
    }

    public String getTimezone() {
        return timezone;
    }

    public void setLocation(String location) {
        this.location = location;
    }

    public String getLocation() {
        return location;
    }

    public void setDate(Date date) {
        this.date = date;
    }

    public Date getDate() {
        return date;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    @Override
    public String toString() {
        StringBuilder sb = new StringBuilder();
        Formatter formatter = new Formatter(sb, Locale.US);
        formatter.format("ID:%s\nLocation:%s\nDate:%s\nTime zone:%s\n", getId(), getLocation(), getDate(), getTimezone());

        return sb.toString();
    }
}

请帮助!!!

更新我在服务中添加了另一个用于执行读操作的方法及其在实现类中的相应逻辑。现在我能够以xml和json格式获得响应。我添加了以下方法

    @WebMethod
@GET
@Path("{location}")
@Descriptions({
    @Description(value = "returns a location data ", target = DocTarget.METHOD),
    @Description(value = "the location data", target = DocTarget.RETURN)
})
public LocationData readLocation(@Description(value = "the string representation of the location") @PathParam("location") @NotNull @Size(max=10, min=5) String location) throws LocationNotFoundException;

但我想在执行创建操作时以json和xml格式进行响应

输出：

而不是德里，我将拥有'位置'，当我点击URL我得到空白页

（评论中的解决方案）

潜在的问题是需要使用URL链接调用JAX-RS方法

@POST
@Path("location")
@Produces({"application/xml","application/json"})
public LocationData createLocation(@Valid LocationData locationData) throws DuplicateLocationException;

无法通过点击URL中的JSON发送POST请求。单击链接或在浏览器工具栏中引入URL执行GET请求。

第二种方法有效，因为使用GET和URL路径/rest/location/{location}。此方法无法接收JSON数据，但可以返回JSON。

您必须使用AJAX来调用REST服务，POST发送json或XML。或者，您可以使用查询参数

在URL中发布数据

rest/location/create?location=Delhi&timezone=

但这不是非常正统的

使用apache cxf，rest websevice响应为null
