mule 异步方式是一种单向调用，调用者不需要获得响应。

异步方式通过inbound和outbound endpoint的exchange-pattern=”one-way”实现。

使用基本的Stdio Transport验证，通过标准输入传输字符串，将其原样传递给标准输出进行显示。相应配置如下：

stdio-asynchronous-single.xml

Java代码

1. <?xml version="1.0" encoding="UTF-8"?>

2. <mule xmlns="http://www.mulesoft.org/schema/mule/core"

3. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

4. xmlns:spring="http://www.springframework.org/schema/beans"

5. xmlns:stdio="http://www.mulesoft.org/schema/mule/stdio"

6. xsi:schemaLocation="

7. http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsd

8. http://www.mulesoft.org/schema/mule/core http://www.mulesoft.org/schema/mule/core/current/mule.xsd

9. http://www.mulesoft.org/schema/mule/stdio http://www.mulesoft.org/schema/mule/stdio/current/mule-stdio.xsd">

10.

11. <stdio:connector name="stdioConnector"

12. messageDelayTime="1234"

13. outputMessage="abc"

14. promptMessage="bcd"

15. promptMessageCode="456"

16. />

17.

18.

19. <model name="model">

20. <service name="echo">

21. <inbound>

22. <stdio:inbound-endpoint system="IN" exchange-pattern="one-way" />

23. </inbound>

24.

25. <component>

26. <singleton-object class="com.easyway.esb.mule.stdio.StdIo" />

27. </component>

28. <outbound>

29. <pass-through-router>

30. <stdio:outbound-endpoint system="OUT" exchange-pattern="one-way" />

31. </pass-through-router>

32. </outbound>

33. </service>

34. </model>

35. </mule>

测试代码:

Java代码

1. String configFile = "stdio-asynchronous-single.xml";

2. String[] configFileArr = new String[] {configFile };

3. MuleContextFactory muleContextFactory = new DefaultMuleContextFactory();

4. MuleContext muleContext = muleContextFactory.createMuleContext(new SpringXmlConfigurationBuilder(

5. configFileArr));

6. muleContext.start();

异步方式适用于简单的消息传递的场景。
