我在我的 spring mvc 项目中使用 solr：

以下是相关代码：

我的配置：

<bean id="solrServer" class="org.apache.solr.client.solrj.impl.CommonsHttpSolrServer">
        <constructor-arg value="http://localhost:8180/sorl"/>
        <property name="connectionTimeout" value="1000"/>
        <property name="defaultMaxConnectionsPerHost" value="32"/>
        <property name="maxTotalConnections" value="128"/>
</bean>

我的域名：

...
@Entity
@Indexed
@Table(name="MySubject")
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public class MySubject extends BaseObject
{

    private static final long serialVersionUID = 1L;

    @Column
    @Field(index=Index.YES, analyze=Analyze.YES, store=Store.NO)
    @org.apache.solr.client.solrj.beans.Field("type")
    private String type;
.....

索引代码：

try {
            solrServer.addBean(subject);
            solrServer.commit();
        } catch (IOException | SolrServerException e) {
            e.printStackTrace();
        }

我得到了例外：

Bad Request

    at org.apache.solr.client.solrj.SolrServer.addBean(SolrServer.java:131)

在 solr 服务器中，日志为：
