Jooq DataTypeException 自 Spring.Boot 2.4.x

Question

自升级到 Spring Boot 2.4.x 以来，我在检索数据时收到 DataTypeException。它适用于 2.3.9.RELEASE.

org.jooq.exception.DataTypeException: No Converter found for types MyBaseType and MyInheritType1 at 
org.jooq.impl.Tools.converterOrFail(Tools.java:1132) at      
org.jooq.impl.Tools.converterOrFail(Tools.java:1148) at 
org.jooq.impl.AbstractRecord.get(AbstractRecord.java:270) at 
org.jooq.impl.AbstractResultQuery.fetchOne(AbstractResultQuery.java:576) at 
org.jooq.impl.SelectImpl.fetchOne(SelectImpl.java:3019)

MyInheritType1 扩展了 MyBaseType。类使用的是 lombok @Data，所以它们应该有合适的 setter。

@Data
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, property = "_class")
@JsonSubTypes(
        {
                @JsonSubTypes.Type(value = MyInheritType1.class, name = "Type1"),
                @JsonSubTypes.Type(value = MyInheritType2.class, name = "Type2")
        })
public class MyBaseType 
{
    private UUID id;
    private String disclaimerLongText = "";
    private LocalDateTime creationTime;
    private Map<UUID, String> images = new HashMap<>();
}

继承类型：

@Data
public class MyInheritType1 extends MyBaseType 
{
    private String baseMap;
    private EnumType someEnum;
    private List<LayerType> layerTypes = new ArrayList<>();
    private double[] center;
}

我这样检索数据：

return dsl.select(PROJECT.DETAILS).from(PROJECT)
                .where(PROJECT.ID.eq(id.toString()))
                .fetchOne(PROJECT.DETAILS, MyInheritType1.class);

PROJECT.DETAILS 定义为：

public final TableField<ProjectRecord, ProjectDetails> DETAILS = createField(DSL.name("details"), SQLDataType.JSONB.nullable(false), this, "", new ProjectDetailsBinding());

ProjectDetailsBinding 如下所示：

public class ProjectDetailsBinding extends JsonBBinding<MyBaseType>
{
    @Override
    protected Class<ProjectDetails> getBindingType()
    {
        return MyBaseType.class;
    }
}

public abstract class JsonBBinding<T> implements Binding<JSONB, T>
{
    private ObjectMapper objectMapper = new ObjectMapper()
            .registerModule(new JavaTimeModule());

    protected abstract Class<T> getBindingType();

    @Override
    public Converter<JSONB, T> converter()
    {
        return new Converter<JSONB, T>()
        {
            @Override
            public T from(JSONB o)
            {
                if (o == null)
                    return null;
                try
                {
                    return objectMapper.readValue(o.data(), getBindingType());
                } catch (Exception e)
                {
                    e.printStackTrace();
                }
                return null;
            }

            @Override
            public JSONB to(T t)
            {
                try
                {
                    return JSONB.valueOf(objectMapper.writeValueAsString(t));
                } catch (JsonProcessingException e)
                {
                    e.printStackTrace();
                }
                return null;
            }

            @Override
            public Class<JSONB> fromType()
            {
                return JSONB.class;
            }

            @Override
            public Class<T> toType()
            {
                return getBindingType();
            }
        };
    }
    [..]
}

因为它适用于 2.3.9.RELEASE，我想知道 Spring Boot 或 Jooq 中发生了什么变化，现在会导致这种不同的行为吗？

看起来 https://github.com/jOOQ/jOOQ/issues/11762, fixed for 3.15.0 and 3.14.9, to be released soon. You can try building 3.14.9 from github or use a snapshot build from here: https://www.jooq.org/download/versions 如果您已获得许可，请查看是否可以解决您的问题。

或者，您可以尝试使用 the fixed version of the DefaultConverterProvider 并在您的 Configuration 中使用它。

Since it worked with 2.3.9.RELEASE, I am wondering what changed in Spring Boot or Jooq, that would cause this different behavior now?

通常，Spring 引导升级伴随 jOOQ 升级。你也可以将你的 jOOQ 依赖降级到你之前使用的 Spring Boot 2.3.9
