Java 在Google应用程序引擎上运行应用程序返回创建Bean错误

我已经构建了一个简单的SpringMVC应用程序，它可以在本地机器上完美地工作。然而，在将其上传到Google App Engine后，我收到一个HTTP 500错误，并从日志中收到以下错误：

Uncaught exception from servlet javax.servlet.UnavailableException: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter]: Constructor threw exception; nested exception is java.lang.NoSuchMethodError: com.fasterxml.jackson.annotation.JsonFormat$Value.empty()Lcom/fasterxml/jackson/annotation/JsonFormat$Value;

我的pom如下，因为我觉得这可能是问题所在：

有人能帮我解决这个问题吗，因为我有点被困在哪里了？

检查你的

mvn dependency:tree

，你的类中似乎有不兼容的Jackson版本PatchThank you@IgorArtamonov-这确实是个错误。
