Let's consider a simple Postgres database with only one table and one column, that is of type DATE, i.e.:

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

From the Hibernate documentation regarding basic types and PostgresSQL documentation regarding using Java 8 Date and Time classes, I can clearly see that I should be able to map that table like this:

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

quite easily, without a need to write @Temporal or any stuff alike. From the Hibernate documentation I can read:

Because the mapping between Java 8 Date/Time classes and the SQL types is implicit, there is not need to specify the @Temporal annotation. Setting it on the java.time classes throws the following exception: org.hibernate.AnnotationException: @Temporal should only be set on a java.util.Date or java.util.Calendar property

However, I'm getting an error

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

In my pom.xml file I've got:

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

and since I'm also using Spring Boot, in application.properties I've got

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

Am I wrong about documentation? Should I write a Converter or is there any other way?

EDIT
Currently my pom.xml file looks like this:

感谢 Ruslan K. 的建议和这个答案https://stackoverflow.com/a/44455146/4671908我能够pom.xml正确修改我的。不幸的是spring-boot-starter-data-jpa 1.5.6.RELEASE，单独不支持最新的 Hibernate 修改，所以我排除了hibernate-core和hibernate-entitymanagerfrom pom.xml，现在看起来像这样

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-jpa</artifactId>

您应该使用更新版本的 Hibernate。

我不能说哪个版本开始支持 Java 8 Dates，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：如果您使用spring-boot-starter-data-jpa，则应从依赖项中排除hibernate-core 。
