Question

我目前在Springboot应用程序中设置Hibernate Envers时遇到问题。我的一个模型中有一个enum类型的枚举，在我的PostgreSQL数据库中，该列的类型为＆＃34; Type＆＃34;。

财产：

@Enumerated(STRING)
@Type(type = "pgsql_enum")
private VehicleTypes vehicleType;

此属性的模型类注释为：

@Entity(name = "cars")
@Audited
@TypeDef(name = "pgsql_enum", typeClass = PostgreSqlEnumType.class)

和自定义类型＆＃34; PostgreSqlEnumType＆＃34;是：

public class PostgreSqlEnumType extends EnumType {
@Override
public void nullSafeSet(PreparedStatement st, Object value, int index, SessionImplementor session) throws HibernateException, SQLException {
    if (value == null) {
        st.setNull(index, OTHER);
    } else {
        st.setObject(index, value.toString(), OTHER);
    }
}}

不幸的是，当我构建这个时，我收到以下错误：

我似乎无法通过休眠来识别此自定义类型。在实施Envers之前，这已经编译好了。

版本：

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

PostgreSQL类型定义：

CREATE TYPE customer_cars.vehicle_types AS ENUM
('CAR', 'PUP');

对不起所有转储，我们将非常感谢任何帮助！

谢谢！

此问题已通过HHH-12304解决。

您需要更新到包含该修补程序的版本，以避免遗憾。由于这不是向后移植到5.1，因此您需要考虑包含该修复的最新5.2.x版本之一。

Hibernate Envers具有属性的自定义类型
