java - hibernate 搜索配置

Question

我使用 hibernate search 和 elastic search 作为后端。当我在 xml 文件中配置 hibernate 和 hibernatesearch 时，一切正常，但是当我在 java 类中配置它时，会出现此警告，并且在我的搜索中找不到任何内容。xml配置是:

<properties>
        <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3399/elastic" />
        <property name="hibernate.connection.username" value="admin" />
        <property name="hibernate.connection.password" value="admin" />

        <property name="hibernate.show_sql" value="true" />

        <property name="hibernate.search.default.indexmanager" value="elasticsearch"/>
        <property name="hibernate.search.default.elasticsearch.host" value="http://127.0.0.1:9400"/>
        <property name="hibernate.search.default.elasticsearch.index_schema_management_strategy" value="CREATE"/>
        <property name="hibernate.search.default.elasticsearch.required_index_status" value="YELLOW"/>

    </properties>

java类配置是:

java.util.Properties settings = new java.util.Properties();
            settings.put(org.hibernate.cfg.Environment.DRIVER, "com.mysql.cj.jdbc.Driver");
            settings.put(org.hibernate.cfg.Environment.URL, "jdbc:mysql://127.0.0.1:3399/elastic");
            settings.put(org.hibernate.cfg.Environment.USER, "admin");
            settings.put(org.hibernate.cfg.Environment.PASS, "admin");
           settings.put(org.hibernate.cfg.Environment.DIALECT,"org.hibernate.dialect.MySQL8Dialect");
            settings.put(org.hibernate.cfg.Environment.SHOW_SQL, "true");
            settings.put(org.hibernate.cfg.Environment.CURRENT_SESSION_CONTEXT_CLASS, "thread");
            settings.put(org.hibernate.cfg.Environment.POOL_SIZE, "5");
settings.put("hibernate.search.default.indexmanager", "elasticsearch");
            settings.put("hibernate.search.default.elasticsearch.host", "http://127.0.0.1:9400");
            settings.put("hibernate.search.default.elasticsearch.index_schema_management_strategy", "CREATE");
            settings.put("hibernate.search.default.elasticsearch.required_index_status", "YELLOW");

警告是:

WARNING: request [HEAD http://127.0.0.1:9400/com.radar.elasticsearch.videogame] returned 1 warnings: [299 Elasticsearch-6.8.0-65b6179 "[types removal] The parameter include_type_name should be explicitly specified in get indices requests to prepare for 7.0. In 7.0 include_type_name will default to 'false', which means responses will omit the type name in mapping definitions."]

Answer 1

您使用的是 Elasticsearch 6.8，其中 types 已弃用。请引用removal of types欲了解更多信息，

您需要传递 _doc 而不是类型名称，否则如果您在所有 API 中使用自己的 type 名称，则使用 include_type_name。

请引用this官方博客了解更多信息

If you plan to upgrade without downtime in a rolling fashion, you should upgrade to 6.8 first, which is the only 6.x release to have some features like support for the include_type_name parameter, which is required to upgrade to 7.0 smoothly.
