Java 8 中使用 Hibernate 5+ 的 PostgreSQL 9.6 DATE 列映射

PostgreSQL 9.6 DATE column mapping using Hibernate 5+ in Java 8

让我们考虑一个简单的 Postgres 数据库,它只有一个 table 和一列,类型为 DATE,即:

CREATE DATABASE test;
CREATE TABLE test_table
(
    date_test DATE NOT NULL DEFAULT CURRENT_DATE
);

Hibernate documentation regarding basic types and PostgresSQL documentation 关于使用 Java 8 日期和时间 类,我可以清楚地看到我应该能够像这样映射 table:

@Entity
@Table(name = "test_table")
public class TestTable
{
    @Column(name = "date_test")
    private LocalDate dateTest;
}

很容易,不需要写 @Temporal 或任何类似的东西。从 Hibernate 文档中我可以读到:

因为Java8Date/Time类和SQL类型之间的映射是隐式的,所以不需要指定@Temporal注解。在 java.time 类 上设置它会引发以下异常: org.hibernate.AnnotationException: @Temporal should only be set on a java.util.Date or java.util.Calendar property

但是,我遇到了一个错误

Schema-validation: wrong column type encountered in column [date_test] in table [test_table]; found [date (Types#DATE)], but expecting [bytea (Types#VARBINARY)]

在我的 pom.xml 文件中我有:

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>9.4-1206-jdbc42</version>
</dependency>

并且因为我也在使用 Spring 启动,所以在 application.properties 我有

spring.jpa.database-platform=org.hibernate.dialect.PostgreSQL9Dialect

我对文档的理解有误吗?我应该写一个转换器还是有其他方法?

现在我得到:

java.lang.NoSuchMethodError:org.hibernate.engine.spi.Session‌​FactoryImplementor.g‌​etProperties()Ljava/‌​util/Properties;

您应该使用更新版本的 Hibernate。

我不能说哪个版本开始支持Java8个日期,但在我的项目中我使用hibernate-core:5.2.6.Final.

我在使用 spring-boot-starter-data-jpa:1.5.6.RELEASE 时遇到了类似的问题,这取决于 hibernate-core:5.0.12.Final.

注意:如果你使用了spring-boot-starter-data-jpa,你应该排除hibernate-core 来自依赖项。

感谢 Ruslan K. 的建议和这个答案 我能够正确地修改我的 pom.xml。不幸的是 spring-boot-starter-data-jpa 1.5.6.RELEASE 单独不支持最新的 Hibernate 修改,所以我从 pom.xml 中排除了 hibernate-corehibernate-entitymanager,现在看起来像这样
