SpringBoot and jackson.databind compatibility error reporting problem

———- ——

1、SpringBoot version V2.0.0
Its dependency on jackson-databind version is V2.9.4, when reading parameters from the configuration file application.properties to assign to the bean, it keeps reporting the following error.
java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.JavaType.isReferenceType()Z
at com.fasterxml.jackson.databind.deser.DeserializerCache._createDeserializer2(DeserializerCache.java:400)
at com.fasterxml.jackson.databind.deser.DeserializerCache._createDeserializer(DeserializerCache.java:352)
at com.fasterxml.jackson.databind.deser.DeserializerCache._createAndCache2(DeserializerCache.java:264)
at com.fasterxml.jackson.databind.deser.DeserializerCache._createAndCacheValueDeserializer(DeserializerCache.java:244)
at com.fasterxml.jackson.databind.deser.DeserializerCache.hasValueDeserializerFor(DeserializerCache.java:191)
at com.fasterxml.jackson.databind.DeserializationContext.hasValueDeserializerFor(DeserializationContext.java:422)

The problem was solved after checking that the version was incompatible and upgrading jackson-databind to V2.9.6

<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.9.6</version>
</dependency>

Possible causes.

Dependency conflict, or wrong version of dependency

Solution.

In springboot is to use jackson to use this

Dependencies.
