java - 创建存储库后 Elasticsearch 无法工作没有类型为 'java.lang.Class>' 的合格 bean

Question

您好，我在使用 Spring Data ElasticSearch 时遇到问题，我可以与 elasticSearch 连接，但在创建存储库后，我的程序停止工作，这是我的代码。预先感谢您帮助解决此问题

@Configuration
@EnableElasticsearchRepositories(basePackages = "com.storyworld.repository.elastic")
public class ElasticSearchConfig {

private static final String PROPERTY_ELASTIC_HOST = "localhost";
private static final int PROPERTY_ELASTIC_PORT = 9300;
private static final String PROPERTY_ELASTIC_CLUSTER_NAME = "elasticsearch";

@Bean
public ElasticsearchOperations elasticsearchTemplate() throws Exception {
    return new ElasticsearchTemplate(client());
}

@Bean
public Client client() throws Exception {
    Settings esSettings = Settings.settingsBuilder().put("cluster.name", PROPERTY_ELASTIC_CLUSTER_NAME).build();

    return TransportClient.builder().settings(esSettings).build().addTransportAddress(
            new InetSocketTransportAddress(InetAddress.getByName(PROPERTY_ELASTIC_HOST), PROPERTY_ELASTIC_PORT));
}

}

这是我的存储库:

public interface ChatRepository extends ElasticsearchRepository<Chat, String>{}

和类(class)聊天:

@Document(indexName = "chatest", type = "chat")
public class Chat {

    @Id
    private String id;

    private String message;
}

创建存储库后出现错误:

我认为出现此问题是因为 JPARepository 这是 JPA 的配置

@Configuration
@EnableJpaRepositories(basePackages = "com.storyworld.repository.sql")
public class MySQLConfig {

    private static final String PROPERTY_NAME_DATABASE_DRIVER = "com.mysql.jdbc.Driver";
    private static final String PROPERTY_NAME_DATABASE_PASSWORD = "root";
    private static final String PROPERTY_NAME_DATABASE_URL = "jdbc:mysql://localhost:3306/storyworld?useSSL=false";
    private static final String PROPERTY_NAME_DATABASE_USERNAME = "root";

    private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "org.hibernate.dialect.MySQL5Dialect";
    private static final String PROPERTY_NAME_HIBERNATE_SHOW_SQL = "true";
    private static final String PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN = "com.storyworld.domain.sql";
    private static final String PROPERTY_NAME_HIBERNATE_AUTO = "update";

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName(PROPERTY_NAME_DATABASE_DRIVER);
        dataSource.setUrl(PROPERTY_NAME_DATABASE_URL);
        dataSource.setUsername(PROPERTY_NAME_DATABASE_USERNAME);
        dataSource.setPassword(PROPERTY_NAME_DATABASE_PASSWORD);
        return dataSource;
    }

    private Properties getHibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.show_sql", PROPERTY_NAME_HIBERNATE_SHOW_SQL);
        properties.put("hibernate.dialect", PROPERTY_NAME_HIBERNATE_DIALECT);
        properties.put("hibernate.hbm2ddl.auto", PROPERTY_NAME_HIBERNATE_AUTO);
        return properties;
    }

    @Bean
    public EntityManagerFactory entityManagerFactory() {
        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setGenerateDdl(true);

        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setPackagesToScan(PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN);
        factory.setDataSource(dataSource());
        factory.setJpaProperties(getHibernateProperties());
        factory.afterPropertiesSet();

        return factory.getObject();
    }

    @Bean
    public PlatformTransactionManager transactionManager() {
        JpaTransactionManager txManager = new JpaTransactionManager();
        txManager.setEntityManagerFactory(entityManagerFactory());
        return txManager;
    }
}

我认为，可能是因为依赖冲突，因为 Spring data elastic search 和 spring data JPA 共享公共(public)依赖。

我正在使用此代码，请尝试使用该代码。我相信它会解决您的问题:-

<!-- Spring ElasticSearch Data JPA-->
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-elasticsearch</artifactId>
    <version>2.0.1.RELEASE</version>
</dependency>
