metaq consumer

package com.pay.metaq;import com.alibaba.fastjson.JSON;import com.taobao.metamorphosis.client.extension.spring.DefaultMessageListener;import com.taobao.metamorphosis.client.extension.spring.MetaqMessage;public class MetaqTestListener extends DefaultMessageListener<String> {  @Override  public void onReceiveMessages(MetaqMessage<String> msg) {    String y = msg.getBody();    System.out.println(JSON.toJSONString(msg));    System.out.println(y);  }}

metaq producer

package com.pay.tests.combine;import java.io.BufferedReader;import java.io.InputStreamReader;import java.util.Date;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import com.taobao.metamorphosis.client.extension.spring.MessageBuilder;import com.taobao.metamorphosis.client.extension.spring.MetaqTemplate;import api.pay.combine.dto.PayItemReqDto;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration("/notenv/applicationContext.xml")public class MetaqTest {  @Autowired  private MetaqTemplate metaqTemplate;  @Test  public void test01() throws Exception {    PayItemReqDto dto = new PayItemReqDto();    BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));    String line = null;    while ((line = reader.readLine()) != null) {      dto.setOrderNo("order001");      dto.setTotalFee(1);      dto.setSpName("spname001");      dto.setTimeOut(new Date());      dto.setSpDetail(line);      metaqTemplate.send(MessageBuilder.withTopic("test").withBody(dto));    }  }}
