Question

我在solr v6.0.0

的schema.xml文件中创建了2个不同的字段

<field name="company_id" type="anand_custom_definition" indexed="false" stored="true" required="true" multiValued="false" />
<field name="project_name" type="anand_custom_definition" indexed="true" stored="true" required="true" multiValued="false" />

当我尝试使用solrj向solr添加数据时，我得到了 缺少必填字段：company_id

我的插入数据的代码是

public class JDBC {
private static final String DB_URL = "jdbc:mysql://192.168.0.237:3306/anandDatabase?autoReconnect=true";
private static final String USER_NAME = "anand";
private static final String PASSWORD = "anand";
private static final String SOLR_URL = "http://192.168.0.237:8983/solr/anandSampleCollection";
private static SolrClient solrClient;

private static final Logger lOGGER = Logger.getLogger(JDBC.class);

public static void main(String[] args) {
    Connection conn = null;
    Statement stmt = null;

    try {
        Class.forName(MYSQL_DRIVER);
        conn = DriverManager.getConnection(DB_URL, USER_NAME, PASSWORD);
        stmt = conn.createStatement();
        String query = "SELECT id,public_id,name,description,code,company_id FROM project p";
        ResultSet rs = stmt.executeQuery(query);
        ResultSetMetaData resultSetMetaData = rs.getMetaData();
        int numColumns = resultSetMetaData.getColumnCount();
        String[] colNames = new String[numColumns + 1];
        int[] colNo = new int[numColumns + 1];

        for (int i = 1; i < (numColumns + 1); i++) {
            if (resultSetMetaData.getColumnName(i) != "null") {
                colNames[i] = resultSetMetaData.getColumnName(i);
            }
        }
        Collection<SolrInputDocument> docs = new ArrayList<SolrInputDocument>();
        solrClient = new HttpSolrClient(SOLR_URL.trim());            
        System.out.println(solrClient.ping());                                                
        while (rs.next()) {                
            SolrInputDocument doc = new SolrInputDocument();
            doc.addField("project_company_id", rs.getInt("company_id"));
            solrClient.add(doc);                
            docs.add(doc);
            doc = null;
        }
        UpdateResponse updateResponse = solrClient.commit();
        System.out.println(updateResponse.getStatus());
        rs.close();
        stmt.close();
        conn.close();
    } catch (Exception ex) {
        System.out.println("Error OCcurred"+ex.getMessage());
        ex.printStackTrace();
    }
}

}

异常的堆栈跟踪是

当我尝试插入project_name值时，任何人都可以通知我为什么我要获取company_id错误

Answer 1

嗯，错误是由company_id字段没有任何值造成的。查看代码，您永远不会为company_id字段添加值：

doc.addField("project_company_id", rs.getInt("company_id"));

project_company_id与company_id不同。

插入数据时solr丢失必填字段错误
