Question

我曾尝试使用Jersey和Jackson将java对象序列化为json并发布，但是，当java对象中的某些字段为null时，我需要发送没有该字段的json。

Java对象如下

public class ProbeData
{
    private String deviceId;
    @JsonInclude(Include.NON_NULL)
    private Double[] location = null;
    private Map<String, String> tags = new HashMap<String, String>();

    public ProbeData() {}

    public ProbeData(String deviceId, Double[] location, Map<String, String> tags)
    {
       this.deviceId = deviceId;
       this.location = location;
       this.tags = tags;
    }
}

泽西岛邮政请求如下

    baseURL = "http://localhost:9090/";
    clientConfig = new ClientConfig().register(new JacksonFeature());
    client = ClientBuilder.newClient(clientConfig);
    HttpAuthenticationFeature auth = HttpAuthenticationFeature.basic("admin", "admin");
    webTarget = client.target(baseURL).register(auth);

    webTarget.path(serviceName).request(MediaType.APPLICATION_JSON_TYPE).post(Entity.entity(probeData, MediaType.APPLICATION_JSON), Response.class).getStatus();

然而，Json仍然成为

 "deviceId" : "1000000002",
 "location" : [
         0,
         0
 ],
 "tags" : {

 },

我期待的地方

"deviceId" : "1000000002",
 "tags" : {

 },

导入和mvn依赖关系如下

import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.annotation.JsonInclude.Include;

    <dependency>
        <groupId>org.glassfish.jersey.core</groupId>
        <artifactId>jersey-client</artifactId>
        <version>2.10.1</version>
    </dependency>
    <dependency>
        <groupId>org.glassfish.jersey.media</groupId>
        <artifactId>jersey-media-json-jackson</artifactId>
        <version>2.10</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-annotations</artifactId>
        <version>2.4.0</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.4.0</version>
    </dependency>

@JsonInclude在使用Jersey webTarget请求时是否有效？

感谢任何帮助
