service_search层删除商品

import cn.itcast.core.service.SolrManagerService;
import org.apache.activemq.command.ActiveMQTextMessage;
import org.springframework.beans.factory.annotation.Autowired;

import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;

/**
 * 自定义监听器
 * 监听消息服务器发送来的商品id
 * 根据商品id 逻辑删除商品对应数据
 */
public class ItemDeleteListener implements MessageListener{

    @Autowired
    private SolrManagerService solrManagerService;

    @Override
    public void onMessage(Message message) {
        //将原生的消息对象强转成ActiveMQTextMessage的文本消息对象,为了方便获取文本消息
        ActiveMQTextMessage atm = (ActiveMQTextMessage) message;
        try {
            //获取文本消息 商品id
            String goodsId = atm.getText();
            //2.到solr索引库中删除
            solrManagerService.deleteItemByGoodsId(Long.valueOf(goodsId));
        } catch (JMSException e) {
            e.printStackTrace();
