SolrJ更新索引数据

SolrJ更新索引数据

SolrJ可以看做是JDBC，有增删改查操作，对Solr中存储的索引数据进行增删改查操作。

Model类

JDBC操作需要Model类，SolrJ操作数据也需要model类。可以使用SolrJ提供的SolrInputDocument类，也可以自己定义bean。我这里场景需要，所以自定义JavaBean，为下面solrJ操作数据做准备。 @Field(value=”UNIQUEKEY”) 对应solr文档中的字段。

public class QydaInfo {
    @Field(value="UNIQUEKEY")
    private String uniquekey;
    @Field(value="QYDA_QYID")
    private String qyid;
    @Field(value="QYDA_QYMC")
    private String qymc;
    @Field(value="QYDA_SHXYDM")
    private String shxydm;
    @Field(value="QYDA_SSZCH")
    private String sszch;
    @Field(value="QYDA_ZZJGDM")
    private String zzjgdm;
    @Field(value="QYDA_QYBM")
    private String qybm;
    @Field(value="QYDA_ZCDZ")
    private String zcdz;
    @Field(value="UPDATE_TIME")
    private Date updatime;
    @Field(value="QYDA_YWY")
    private Set ywy;
    @Field(value="QYDA_XDR")
    private List xdr;
    @Field(value="QYDA_RYXX")
    private List ryxx;
    @Field(value="QYDA_XKXX")
    private List xkxx;
    @Field(value="QYDA_RCJG")
    private List rcjg;
    @Field(value="QYDA_CYCJ")
    private List cycj;
    @Field(value="QYDA_TSJB")
    private List tsjb;
    @Field(value="QYDA_XZZF")
    private List xzzf;
    @Field(value="QYDA_LHDA")
    private List lhda;
    @Field(value="QYDA_CPXX")
    private List cpxx;

    public QydaInfo(){}

    public QydaInfo(String qyid, String qymc, String shxydm, String sszch, String zzjgdm, String qybm,
            String zcdz, Date updatime) {
        this(qyid,qyid,qymc,shxydm,sszch,zzjgdm,qybm,zcdz,updatime);
    }

    public QydaInfo(String uniquekey, String qyid, String qymc, String shxydm, String sszch, String zzjgdm, String qybm,
            String zcdz, Date updatime) {
        this.uniquekey = uniquekey;
        this.qyid = qyid;
        this.qymc = qymc;
        this.shxydm = shxydm;
        this.sszch = sszch;
        this.zzjgdm = zzjgdm;
        this.qybm = qybm;
        this.zcdz = zcdz;
        this.updatime = updatime;
    }
    //省略get、set方法

编写数据服务类

对solr数据进行操作时，需要借助SolrServer抽象类，类似于Spring Jdbctemplate定义基本的功能，提供增删改查操作。

获取SolrServer

可以通过它的实现子类CloudSolrServer、ConcurrentUpdateSolrServer、HttpSolrServer、LBHttpSolrServer获取，我这里使用HttpSolrServer 获取。

public SolrServer getSolrServer(){
    //HttpSolrServer构造方法需要传solr节点url+索引集collection;如果是CloudSolrServer，则需要传zookeeper字节信息。
    SolrServer solr=new HttpSolrServer(SOLR_URL+"gzyj_qyda_core/");
    return solr;
}

编写基本操作

增加和更新操作是一起的、删除是根据uniquekey

/**
 * 添加或更新
 * @param qyda
 */
public void addOrUpdateIndexData(QydaInfo qyda){
        SolrServer solr=this.getSolrServer();
        try {
            solr.addBean(qyda);
            solr.optimize();
        } catch (SolrServerException | IOException e) {
            e.printStackTrace();
        }finally{
            try {
                solr.commit(true,true,true);
            } catch (SolrServerException | IOException e) {
                e.printStackTrace();
            }
        }

    }
    /**
     * 批量添加或更新
     * @param qydaList
     */
    public void addOrUpdateIndexData(List qydaList){
        SolrServer solr=this.getSolrServer();
        try {
            solr.addBeans(qydaList);
            solr.optimize();
        } catch (SolrServerException | IOException e) {
            e.printStackTrace();
        }finally{
            try {
                solr.commit();
            } catch (SolrServerException | IOException e) {
                e.printStackTrace();
            }
        }

    }
    /**
     * 删除
     * @param uniquekey
     */
    public void deleteIndexData(String uniquekey){
        SolrServer solr=this.getSolrServer();
        try {
            solr.deleteById(uniquekey);
            solr.optimize();
        } catch (SolrServerException | IOException e) {
            e.printStackTrace();
        }finally{
            try {
                solr.commit();
            } catch (SolrServerException | IOException e) {
                e.printStackTrace();
            }
        }

    }
    /**
     * 批量删除
     * @param uniquekeys
     */
    public void deleteIndexData(List uniquekeys){
        SolrServer solr=this.getSolrServer();
        try {
            solr.deleteById(uniquekeys, 3000);

        } catch (SolrServerException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }finally{
            try {
                solr.commit();
            } catch (SolrServerException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

    }
