Spring integration 设置LoggingHandler的通道
我正在为我的springxd模块编写自己的单元测试(但是,我不打算使用Spring integration 设置LoggingHandler的通道,spring-integration,spring-xd,Spring Integration,Spring Xd,我正在为我的springxd模块编写自己的单元测试(但是,我不打算使用xd.test和xd.dirt) 这是一个处理器模块,我为测试所做的是: 配置上下文: ctx = new ClassPathXmlApplicationContext("config/spring-module.xml"); 获取输入直接通道和发送(消息) 但是对于DirectChannel,我必须为它提供一个subscriber,因此我决定向输出DirectChannel编写一个日志处理程序Bean,就是这样: @Bea
xd.test
和xd.dirt
)
这是一个处理器模块,我为测试所做的是:
配置上下文:
ctx = new ClassPathXmlApplicationContext("config/spring-module.xml");
获取输入
直接通道
和发送(消息)
但是对于DirectChannel
,我必须为它提供一个subscriber
,因此我决定向输出DirectChannel
编写一个日志处理程序
Bean
,就是这样:
@Bean
public LoggingHandler outputLogging(){
LoggingHandler lh = new LoggingHandler("INFO");
lh.setLoggerName("output-logging");
lh.setShouldLogFullMessage(true);
return lh;
}
但我的问题是:我需要loggingHandler
作为输出
频道的订户。因此,我必须以某种方式将其配置为输出
。我得到的解决方案如下:
@Bean
@ServiceActivator(inputChannel = "output")
public LoggingHandler outputLogging(){
LoggingHandler lh = new LoggingHandler("INFO");
lh.setLoggerName("output-logging");
lh.setShouldLogFullMessage(true);
return lh;
}
但是,仍然存在以下方面的例外情况
:

所以,我的问题是:
我是否需要使用xml
或annotation
来配置模块,我不能同时使用它们
如果可以,是否有不使用@ServiceActivator(inputChannel=“output”)
的解决方案,它看起来像:
<int:service-activator input-channel="input" method="trans" output-channel="output">
<bean class="com.example.LoggingHandler" init-method="init" destroy-method="destroy">
...
</bean>
</int:service-activator>
...
实际上我不需要服务激活器
谢谢

由于它是测试用例,我认为您只需导入真正的模块配置并提供一些测试工具,就可以让它工作并完成任务
我甚至认为您使用的是@ServiceActivator
配置
只有在@启用集成
以及@配置
中缺少的问题
另一方面,我最好在队列通道@Bean
上设置@BridgeFrom(“输出”)
,以断言测试结束时的处理器结果。
但无论如何,您都需要@EnableIntegration
更新
嗯。谢谢你的更新代码。现在我明白了。您的TestAll
@Configuration
类未向ApplicationContext
注册的问题。因此,没有人会处理@enableeintegration
并注册您的LoggingHandler
@Bean
等等
试试这个:
@ContextConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@DirtiesContext
public class TestAll {
@Autowired
@Qualifier("input")
private MessageChannel inputChannel;
@Autowired
private PollableChannel resultChannel;
@Test
public void allTest(){
Message<?> msg = composeMsg();
input.send(msg);
Message<?> result = resultChannel.receive(10000);
assertNotNull(result);
// Other asserts
}
@Configuration
@EnableIntegration
@ImportResource("classpath:config/spring-module.xml")
public static class ContextConfiguration {
@BridgeFrom("output")
public PollableChannel resultChannel() {
return new QueueChannel();
}
}
}
@ContextConfiguration
@RunWith(SpringJUnit4ClassRunner.class)
@肮脏的环境

@自动连线

@试验
公共测试(){
消息msg=composeMsg();
输入。发送(msg);
消息结果=结果通道接收(10000);
assertNotNull(结果);
//其他主张
}
@配置

@ImportResource(“classpath:config/spring module.xml”)
公共静态类上下文配置{
@BridgeFrom(“输出”)
公共可轮询频道结果频道(){
返回新的队列通道();
}
}
}
谢谢阿尔特恩,我想我会试试@BridgeForm
。但实际上,我的测试类中同时添加了@enableeintegration
和@Configuration
。我还考虑在运行时添加bean
。无论如何,谢谢你的工作。我用我的代码更新了这个问题,希望它能帮助你发现我的代码有什么问题。
