如何在SolrJ中插入具有多个子Bean的Bean对象 [英] How to insert Bean object which has many child Bean in SolrJ

问题描述

我有一个Bean类活动，该活动将概要文件列表和一个用户Bean相关联.现在，如果我试图通过SOLRJ在Solr中插入这个Activity bean，它将给我空指针异常. 异常是由以下代码引起的:

I have a Bean Class Activity which associates List of Profiles and a User Bean. Now If I am trying to insert this Activity bean in Solr by SOLRJ, it is giving me null pointer exception. The Exception is causing by below piece of code:

public <T> boolean insert (T bean) {
    try {
        UpdateResponse response = solrClient.addBean(bean);
        System.out.println("insert bean ElapsedTime: " + response.getElapsedTime());
        solrClient.commit();
        return true;
    } catch (IOException | SolrServerException e) {
        e.printStackTrace();
    }
    return false;
}
