Question

我遇到了将postgresql类型映射到时区＆＃39;时间戳的问题。在java.time.LocalDateTime上。我正在使用：postgresql，dropwizard with hibernate。

表：

@Override
public void zzm(Intent intent) {
    Log.e(TAG, "zzm : " + intent);
    createBigPictureNotification();        
}

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {

}

核心：

CREATE SEQUENCE "auth"."roles_seq_id";

CREATE TABLE "auth"."roles" (
  id        BIGINT                  NOT NULL    DEFAULT nextval('auth.roles_seq_id'),
  name      VARCHAR(50)             NOT NULL,
  createdat TIMESTAMP WITH TIME ZONE DEFAULT now() NOT NULL
);

ALTER TABLE "auth"."roles" ADD CONSTRAINT "roles_id_pk" PRIMARY KEY (id);

错误：

错误[2017-07-21 08：13：43,465] io.dropwizard.jersey.errors.LoggingExceptionMapper：处理错误请求：b09a66b06dd214bd ......！曹景伟： org.hibernate.type.SerializationException：无法反序列化

的pom.xml：

import lombok.*;

import javax.persistence.*;
import java.io.Serializable;
import java.time.LocalDateTime;

@Getter
@Setter
@ToString(callSuper = true)
@EqualsAndHashCode(callSuper = false)
@AllArgsConstructor
@NoArgsConstructor
@Entity
@Table(schema = "auth", name = "roles")
public class Role implements Serializable {
    private static final long serialVersionUID = 1L;

    @Id
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "roles_id_generator")
    @SequenceGenerator(name = "roles_id_generator", sequenceName = "roles_seq_id")
    @Column(name = "id")
    private Long id;

    @NonNull
    @Column(name = "name", nullable = false)
    private String name;

    @Column(name = "createdat")
    private LocalDateTime createdAt;

}

当我删除<dropwizard.version>1.0.6</dropwizard.version> <postgresql.version>9.4.1212</postgresql.version> <dependency> <groupId>io.dropwizard</groupId> <artifactId>dropwizard-hibernate</artifactId> <version>${dropwizard.version}</version> </dependency> <dependency> <groupId>org.postgresql</groupId> <artifactId>postgresql</artifactId> <version>${postgresql.version}</version> </dependency>或使用createdAt（但我想使用LocalDateTime）时，一切正常。

似乎dropwizard-hibernate:1.0.6捆绑了Hibernate 5.1。根据{{3}}，需要额外的依赖关系来支持java.time类型：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-java8</artifactId>
    <version>5.1.0.Final</version>
</dependency>

此外，从Hibernate 5.2开始，不需要这种额外的依赖性，似乎功能被折叠到主要依赖项中。
