org.springframework.context.ApplicationContextException: Unable to start embedded container； nested

前言

swagger引入后一直报错，尝试多个解决后没办法

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'httpPutFormContentFilter' defined in class path resource 
[org/springframework/boot/autoconfigure/web/WebMvcAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is 
org.springframework.beans.BeanInstantiationException: Failed to instantiate 
[org.springframework.boot.web.filter.OrderedHttpPutFormContentFilter]: Factory method 
'httpPutFormContentFilter' threw exception; nested exception is java.lang.NoClassDefFoundError: Could not initialize class com.fasterxml.jackson.databind.ObjectMapper

解决

解决后发现是依赖的jar版本太高，导致一直启动不起来，所以办法就是降低版本，原先为3.0.0版本
