java - 如何使用 spring data solr 在 solr 中插入嵌套文档？

Question

我需要将此类数据插入到 solr 服务器。

{
    "id":"09123"
    "firstName": "Harshana651175279",
    "lastName": "Samaranayake332146645",
    "department": {
            "id":"001",
            "depName":"dep01"        
        }
}

这些是用于插入数据的 my POJO。

public class SolrCustomer {

    @Id
    @Indexed
    private String id;
    @Field
    @Indexed
    private String firstName;
    @Field
    @Indexed
    private String lastName;
    @Field
    private Department department;

    //getters n setters
}

public class Department {

    @Id
    @Indexed
    private String id;
    @Field
    @Indexed
    private String departmentName;

    //getters n setters
}

没有部门数据它工作正常。但不能作为嵌套文档插入。当我尝试它时，就像这样插入

{
    "firstName": "Harshana651175279",
    "lastName": "Samaranayake332146645",
    "department": [
        "org.ftm.solr.domain.Department@479c1814"
    ],
    "id": "2e204ab3-772d-4af1-a2be-866e21206ecd",
    "_version_": 1536317096485453800
}

这是我为此配置的模式。

<field name="department" type="strings" multiValued="true"/>
<field name="firstName" type="strings" multiValued="false"/>
<field name="id" type="string" indexed="true" required="true" stored="true"/>
<field name="lastName" type="strings" multiValued="false"/>

那么我如何将这些嵌套文档与 solr n spring data solr 一起使用呢？

是的，您可以插入嵌套文档，检查以下问题的答案: SOLRJ-6.0.0: Insertion of a bean object which associate list of bean object is giving null pointer exception
