引入依赖

首先需要在消息发送模块（e3-manager-service）和接收模块（e3-search-service）的pom文件中引入依赖

        <dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-jms</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-context-support</artifactId>
		</dependency>
        <dependency>
			<groupId>org.apache.activemq</groupId>
			<artifactId>activemq-all</artifactId>
		</dependency>

添加商品发送消息（商品ID）

因为queueDestination和topicDestination的class相同，所有不能用@Autowired，用@Resource根据id取

@Autowired
	private JmsTemplate jmsTemplate;
@Resource
	private Destination topicDestination;
@Override
	public E3Result itemAdd(TbItem item, String desc) {
		//生成商品id
		final long id = IDUtils.genItemId();
		//补全item属性
		item.setId(id);
		//'商品状态，1-正常，2-下架，3-删除'
		item.setStatus((byte) 1);
		item.setCreated(new Date());
		item.setUpdated(new Date());
		//向商品表插入数据
		itemMapper.insert(item);
		//创建商品描述表对应的pojo对象
		TbItemDesc itemDesc = new TbItemDesc();
		//补全属性
		itemDesc.setItemId(id);
		itemDesc.setItemDesc(desc);
		itemDesc.setCreated(new Date());
		itemDesc.setUpdated(new Date());
		//插入商品描述表
		itemDescMapper.insert(itemDesc);
		// 发送商品添加消息
		jmsTemplate.send(topicDestination, new MessageCreator() {

			@Override
			public Message createMessage(Session session) throws JMSException {
				// 发送商品ID
				TextMessage message = session.createTextMessage(id + "");
				return message;
			}
		});
		//返回数据
		return E3Result.ok(200);
	}

接收消息（商品ID）查询商品信息，写入索引库

问题：

添加商品-发送商品ID-接收ID-查询商品可能会出现事物没有提交，从而查询结果为空的情况。

思路：

1.接收ID后等待事物提交 Thread.sleep(1000); 1秒

2.在商品添加controller中发送商品ID，此时事物已提交。

package lx.test.search.message;

import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.TextMessage;

import org.apache.solr.client.solrj.SolrServer;
import org.apache.solr.common.SolrInputDocument;
import org.springframework.beans.factory.annotation.Autowired;

import lx.test.pojo.SearchItem;
import lx.test.search.mapper.ItemMapper;
/**
 * 监听商品添加消息，接收消息后，将对应的商品信息同步到索引库
 * @author lx
 *
 */
public class ItemAddMessageListener implements MessageListener {

	@Autowired
	private ItemMapper itemMapper;
	@Autowired
	private SolrServer solrServer;
	@Override
	public void onMessage(Message message) {
		//从消息中取商品id
		try {
		TextMessage textMessage = (TextMessage) message;
		String text = textMessage.getText();
		Long itemid = new Long(text);
		//等待事务提交
		Thread.sleep(1000);
		//根据商品id查询商品信息
		SearchItem searchItem = itemMapper.getItemById(itemid);
		//创建一个文档对象
        SolrInputDocument document = new SolrInputDocument();
        //向文档对象中添加域
        document.addField("id", searchItem.getId());
		document.addField("item_title", searchItem.getTitle());
		document.addField("item_sell_point", searchItem.getSell_point());
		document.addField("item_price", searchItem.getPrice());
		document.addField("item_image", searchItem.getImage());
		document.addField("item_category_name", searchItem.getCategory_name());
		//把文档写入索引库
		solrServer.add(document);
		//提交
		solrServer.commit();
		} catch (Exception e) {
			e.printStackTrace();
		}
		
	}
