Spring Data Solr：无法从存储库中找到属性

Question

在我设法迁移到 Spring Boot 之前，这一切正常。

在我使用 spring-data-solr 版本 : 1.4.0.RELEASE 之前，现在 Boot 刚刚获得版本 1.3.3。

我试图删除 spring-boot-starter-data-solr 并重置为静态定义，但我遇到了同样的问题..

更新我当前的pom.xml：

我目前的SolrConfig.java：

@Configuration
@EnableSolrRepositories(basePackages = "com.repository.solr")
@ComponentScan("com.repository.solr")
public class SolRConfig {

    private final Logger logger = LoggerFactory.getLogger(this.getClass());

    public static final String PROPERTY_SOLR_SERVER_CORE  = "solr.core";

    @Resource
    private Environment environment;
    @Resource OgcParameters ogcParameters;

    @Bean
    public SolrServer solrServer() {
        final OgcParameters.slr slr = ogcParameters.slr();
        if (!environment.containsProperty(PROPERTY_SOLR_SERVER_CORE)) {
            logger.warn("You are running on the default solr core, create or edit the application.properties to avoid this behaviour");
        }

        String solrHostWithCoreIfNecessary = slr.host()
                .concat(slr.core());

        return new HttpSolrServer(solrHostWithCoreIfNecessary);
    }

    @Bean
    public SolrOperations solrTemplate() throws ParserConfigurationException, SAXException, IOException {
        return new SolrTemplate(solrServer());
    }
}

我目前的SolrRepository.java：

@Repository
public interface DocumentSolrRepository extends SolrCrudRepository<Document, Long>, DocumentSolrRepositoryCustom {
    Set<Document> findByTextContaining(@Param("text") String test);
}

我当前的 entity 使用绑定到 SolrRepository 字段的@Field 属性导致服务器启动失败：

@Entity
@JsonIgnoreProperties(ignoreUnknown = true)
public class Document {

    private Long id;
    @Id
    @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="DOCUMENT_SEQ")
    @SequenceGenerator(name="DOCUMENT_SEQ", sequenceName="DOCUMENT_SEQ")
    public Long getId() {
        return id;
    }
    public Document setId(Long id) {
        this.id = id;
        return this;
    }
    /* SOLR Specific Fields */
    @Field("text")
    private String text;
    @Transient @JsonIgnore
    public String getText() {
        return text;
    }
    public Document setText(String text) {
        this.text = text;
        return this;
    }
}

错误记录堆栈跟踪：

您不需要排除或添加任何其他依赖项。相反，您可以使用以下属性简单地定义 spring-data 项目要使用的版本：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.5.RELEASE</version>
</parent>

<properties>
    <spring-data-releasetrain.version>Fowler-SR2</spring-data-releasetrain.version>
</properties>

<dependencies>
    ...
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-solr</artifactId>
    </dependency>
    ...
</dependencies>

不需要其他任何东西。顺便说一句，Fowler-SR2 是 28.07 发布的（它仍然很热）。
