我正在与Grizzly,Jersey和Jackson一起使用REST应用程序,因为Jersey忽略了我的自定义ObjectMapper.

POM依赖:

<dependencies>
    <dependency>
        <groupId>org.glassfish.jersey.containers</groupId>
        <artifactId>jersey-container-grizzly2-servlet</artifactId>
        <version>2.2</version>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.jaxrs</groupId>
        <artifactId>jackson-jaxrs-json-provider</artifactId>
        <version>2.1.4</version>
    </dependency>
</dependencies>

结果版本是:Grizzly 2.3.3,Jackson 2.1.4和Jersey 2.2.

主类(我希望明确注册Jersey组件):

public class Main {
    public static void main(String[] args) {
        try {
            ResourceConfig rc = new ResourceConfig();
            rc.register(ExampleResource.class);
            rc.register(ObjectMapperResolver.class);

            HttpHandler handler = ContainerFactory.createContainer(
                    GrizzlyHttpContainer.class, rc);

            URI uri = new URI("http://0.0.0.0:8080/");

            HttpServer server = GrizzlyHttpServerFactory.createHttpServer(uri);

            ServerConfiguration config = server.getServerConfiguration();
            config.addHttpHandler(handler, "/");

            server.start();
            System.in.read();

        } catch (ProcessingException | URISyntaxException | IOException e) {
            throw new Error("Unable to create HTTP server.", e);
        }
    } …

我正在为REST端点创建一个服务客户端，将JAX-RS客户端用于HTTP请求，并使用Jackson来（反）序列化JSON实体。为了处理JSR-310（Java8）日期/时间对象，我将该com.fasterxml.jackson.datatype:jackson-datatype-jsr310模块作为对服务客户端的依赖项添加，但是我没有使它起作用。

如何配置JAX-RS和/或Jackson使用jsr310模块？

我使用以下依赖项：

<dependency>
  <groupId>javax.ws.rs</groupId>
  <artifactId>javax.ws.rs-api</artifactId>
  <version>${jax-rs.version}</version>
</dependency>
<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
  <artifactId>jackson-annotations</artifactId>
  <version>${jackson.version}</version>
</dependency>
<dependency>
  <groupId>com.fasterxml.jackson.datatype</groupId>
  <artifactId>jackson-datatype-jsr310</artifactId>
  <version>${jackson.version}</version>
</dependency>

我不想使服务客户端（以库形式发布）依赖于任何特定的实现（例如Jersey），因此我仅依赖于JAX-RS API。为了运行集成测试，我添加了：

<dependency>
  <groupId>org.glassfish.jersey.core</groupId>
  <artifactId>jersey-client</artifactId>
  <version>${jersey.version}</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>org.glassfish.jersey.inject</groupId>
  <artifactId>jersey-hk2</artifactId>
  <version>${jersey.version}</version>
  <scope>test</scope>
</dependency>
<dependency>
  <groupId>org.glassfish.jersey.media</groupId>
  <artifactId>jersey-media-json-jackson</artifactId>
  <version>${jersey.version}</version>
  <scope>test</scope>
</dependency>

JAX-RS客户端的实例化是在工厂对象中完成的，如下所示：

import javax.ws.rs.Produces;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;

@Produces
public Client produceClient() {
    return ClientBuilder.newClient();
}

典型的DTO如下所示：

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.annotation.JsonPropertyOrder;

import java.time.Instant;

import static java.util.Objects.requireNonNull;

@JsonPropertyOrder({"n", "t"})
public final class Message {

    private final String name;
    private final …
