MapStruct在源和目标中均找不到属性

Question

源类看起来像：

Data
@Accessors(chain = true)
@Validated
public class OAuth2ClientCreateRequest {

    @NotNull
    Data data;

    @lombok.Data
    @Accessors(chain = true)
    public static class Data {

        @Pattern(regexp = "oauth2_clients")
        private String type;

        @NotNull
        private OAuth2ClientAttributes attributes;
    }

    @lombok.Data
    @Accessors(chain = true)
    public static class OAuth2ClientAttributes {

        @NotNull @Length(min = 10, max = 256)
        private String clientId;
......

目标类如下：

@Accessors(chain = true)
@Getter
@Setter
@ToString
public class OAuth2Client extends BaseEntity<OAuth2Client> implements Serializable {

    @NotNull
    @Length(min = 10, max = 256)
    @JsonProperty
    private String clientId;

........

映射器类：

@Mapper(componentModel = "spring")
public interface OAuth2ClientMapper {

    @Mapping(target = "clientId", source = "attr.clientId")
    OAuth2Client convert(OAuth2ClientCreateRequest.OAuth2ClientAttributes attr);

}

我在执行Maven编译时遇到的错误：

[ERROR] ....../OAuth2ClientMapper.java:[14,52] The type of parameter "attr" has no property named "clientId".
[ERROR] ....../OAuth2ClientMapper.java:[14,52] Unknown property "clientId" in result type .....oauth2authserver.domain.entity.OAuth2Client. Did you mean "null"?

[注意，我在Lombok中使用MapStruct。这里有没有与预处理器有关的问题？

Answer 1

在我的IntelliJ IDE项目中，Lombok在不添加任何注释预处理程序的情况下工作，因为Lombok插件是通过IntelliJ设置下载的。

然后，在pom.xml中添加map-struct依赖项时，我不得不在pom.xml中添加注释预处理器插件mapstruct-processor。然后Lombok开始无法工作。

最后为Lombok和Map-Struct都添加注释处理器，如下所示-

<properties>
    <java.version>11</java.version>
    <mapstruct.version>1.3.1.Final</mapstruct.version>
    <gson.version>2.8.5</gson.version>
</properties>
