我正在尝试将在Kotlin中编写的Spring Cloud Function部署为AWS lambda,但在测试时会出现此错误
{
"errorMessage": "No bean named 'function' available",
"errorType": "org.springframework.beans.factory.NoSuchBeanDefinitionException",
"stackTrace": [
"org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:686)",
"org.springframework.beans.factory.support.AbstractBeanFactory.getMergedLocalBeanDefinition(AbstractBeanFactory.java:1205)",
"org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:292)",
"org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:205)",
"org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1091)",
"org.springframework.cloud.function.adapter.aws.SpringFunctionInitializer.initialize(SpringFunctionInitializer.java:100)",
"org.springframework.cloud.function.adapter.aws.SpringBootRequestHandler.handleRequest(SpringBootRequestHandler.java:44)"
]
}
我可以在我的本地设置uisng spring-boot:run命令上运行它。 我在弹簧5使用弹簧靴2。 这是我的代码的样子。
Application.kts
@SpringBootApplication
@FunctionScan
class Application
fun main(args: Array<String>) {
runApplication<Application>(*args)
}
Function.kt
package `in`.nafa.job.inventoryfulfillment
import org.springframework.stereotype.Component
import java.util.function.Function
@Component("function")
class Function : Function<Incoming, Outgoinig> {
override fun apply(t: Incoming): Outgoinig {
return Outgoinig()
}
}
传入和传出是空类,没有任何属性。
Handler.kt
package `in`.nafa.job.inventoryfulfillment
import org.springframework.cloud.function.adapter.aws.SpringBootRequestHandler
class Handler : SpringBootRequestHandler<Incoming, Outgoinig>()
的pom.xml 此pom的大部分内容都是从spring cloud function samples

答案 0 :(得分:2)
我能够通过从
更改pom.xml中的启动类来实现它<start-class>in.nafa.job.inventoryfulfillment.InventoryFulfillmentApplicationKt</start-class>
到
<start-class>in.nafa.job.inventoryfulfillment.InventoryFulfillmentApplication</start-class>
希望这有助于某人..
