非常容易，无需编写
@Temporal
或任何类似的东西。从Hibernate文档中，我可以阅读：

因为Java8日期/时间类和SQL类型之间的映射是隐式的，所以不需要指定@Temporal注释。在java.time类上设置它会引发以下异常： 
org.hibernate.AnnotationException:@Temporal应仅在java.util.Date或java.util.Calendar属性上设置

然而，我得到了一个错误

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，我得到了：

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

我对文档的理解错了吗？我应该写一个转换器还是有其他方法

编辑
当前我的
pom.xml
文件如下所示：

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

您应该使用更新版本的Hibernate

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

在使用SpringBootStarter数据jpa:1.5.6.RELEASE时，我遇到了类似的问题，这取决于hibernate内核：5.0.12.Final

注意：如果您使用spring boot starter数据jpa，您应该将hibernate core从依赖项中排除。

多亏了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，
springbootstarter数据jpa1.5.6.RELEASE
本身不支持最新的Hibernate修改，所以我从
pom.xml
中排除了
Hibernate核心
和
Hibernate entitymanager
，现在看起来像这样
