WebService学习(八)——利用websevice接口封装activemq的生产者，并监听到消息
本系列第五篇，利用myeclipse生成基于jax-ws的接口，并能成功访问wsdl后，接下其他操作
1.service接口：
-
/**
-
* 用于外部系统调用接口
-
*
-
* @author Administrator
-
*
-
*/
-
public
interface IUserService {
-
-
public Users getUsersByUserCode(String userCode);
-
-
public Users selectByPrimaryKey(Integer id);
-
-
public int deleteByPrimaryKey(Integer id);
-
-
public int insert(Users record);
-
-
public int insertSelective(Users record);
-
-
public int updateByPrimaryKeySelective(Users record);
-
-
public int updateByPrimaryKey(Users record);
-
-
}
2.UserService类代码
-
/**

-
@Service

-
// 增删改的方法，都需要向消息队列中发送数据
-
/**

-
StringBuffer buf =
new StringBuffer();

buf.append(

-
@Autowired
-
private JmsTemplate jmsTemplate;

-
*/
-
public void sendMessage(Destination destination, final String msg) {
-
System.out.println(Thread.currentThread().getName() +

7.监听器的类

*/
-
public
class userQueueMessageListener implements MessageListener {
-
private UserService userService;
-
// 当收到消息后，自动调用该方法
-
@Override
-
public void onMessage(Message message) {
-
TextMessage tm = (TextMessage) message;
-
try {
-
System.out.println(
"userQueueMessageListener监听到了文本消息：\t" + tm.getText());
-
//处理业务逻辑
-
}
catch (JMSException e) {
-
e.printStackTrace();
-
}
-
-
}
-
-
}
8.测试方法
-
/**
-
* 用户登录
-
*/
-
public String login() {
-
setUtfEncoding();
-
String userCode = getRequest().getParameter(
"userCode");
-
String password = getRequest().getParameter(
"password");
-
-
// String param = "登录成功";
-
// producerServiceUser.sendMessage(destination, param);
-
//
-
// String param1 = "日志成功";
-
// producerServiceLog.sendMessage(destination1, param1);
-
int id=
1;
-
userService.deleteByPrimaryKeyPort(id);
-
return SUCCESS;
-
}
最后能成功监听到调用接口封装的方法传输过来的数据，真实的的接口调用，可以参考我soap调接口那篇
简单的记录下来，毕竟是自己做项目遇到的难点......
