我從start.spring.io創建了一個具有Web依賴性的Spring Boot應用程序。然後我加入AWS SDK依賴作爲 -Spring Boot上的Jackson數據綁定依賴錯誤,AWS應用
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk</artifactId>
<version>1.11.157</version>
</dependency>
在builing的應用程序,我收到以下錯誤 -
2017-07-02 03:02:11.431 WARN 18412 --- [ main] ConfigServletWebServerApplicationContext : Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'requestMappingHandlerAdapter' defined in class path resource [org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration$EnableWebMvcConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter]: Factory method 'requestMappingHandlerAdapter' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'messageConverters' defined in class path resource [org/springframework/boot/autoconfigure/http/HttpMessageConvertersAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.autoconfigure.http.HttpMessageConverters]: Factory method 'messageConverters' threw exception; nested exception is java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/Module
其中
nested exception is java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/Module
在錯誤日誌中多次出現。
我檢查了樹和依賴關係層次結構等,但是如果我從AWS依賴項中排除Jackson,仍然會發生同樣的錯誤。 如何解決此錯誤?

不,我不是來自AWS,引導但不包括在同一時間,但只能從其中的一個。我也分別加了傑克遜。所以,我嘗試了所有的可能性。 –
@DevS我沒有看到單獨的包含在任何地方。 – chrylis
@DevS否傑克遜在您的示例中被定義爲單獨的依賴項。 –
