Springboot 1.4 /单元测试错误（多次注册hibernate AttributeConverter）

我有一个奇怪的问题。

我刚用Spring Boot 1.4.0（之前的1.3.4）更新了我的项目。 我的项目有大约70个单元测试（junit4）。

当我用maven运行我的测试时：

mvn clean install

然后我收到很多这样的错误：

以下是我的＆＃34;多豆＆＃34;看起来像：

@Converter(autoApply = true)
public class LocalDateAttributeConverter implements     AttributeConverter<LocalDate, Date>
{

    @Override
    public Date convertToDatabaseColumn(LocalDate locDate)
    {
        return (locDate == null ? null : Date.valueOf(locDate));
    }

    @Override
    public LocalDate convertToEntityAttribute(Date sqlDate)
    {
        return (sqlDate == null ? null : sqlDate.toLocalDate());
    }
}

单元测试之一：

@RunWith(SpringRunner.class)
@SpringBootTest
public class XxxTest
{
}

看起来，这是一个休眠错误，但我找不到这个问题的正确答案。 当我做一个简单的包测试（有3个测试类）时，它工作正常。 但是整个＆＃34; mvn测试＆＃34;导致错误。

以下是我的依赖项：

  • spring boot 1.4.0
  • spring 4.3.2
  • hibernate 5.0.1
  • junit 4.12
  • 行家-万无一失-插件：2.18.1

我对任何进一步的线索感兴趣！

hibernate支持Java 8 DateTime API。

您不需要使用属性转换器将LocalDate转换为Date，您只需要在pom.xml中对Hibernate 5.1.x及之前具有以下依赖关系。 

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-java8</artifactId>
        <version>{hibernate.version}</version>
    </dependency>

对于Hibernate 5.2+，Java8模块已合并到Hibernate中。

感谢编辑，来自hibernate-java8 5.2.1自述

特定于Java8的Hibernate O / RM功能已合并到hibernate-core模块中，使得这个hibernate-java8模块成为可能 过时。该模块将在Hibernate ORM 6.0中删除。它只保留在各种消费者的期望中 许多Hibernate版本中的静态工件名称集。请参阅https://hibernate.atlassian.net/browse/HHH-10883
