Question

Failed to find class `com.fasterxml.jackson.databind.deser.std.DateDeserializers$TimestampDeserializer` for handling values of type
 `java.sql.Timestamp`, problem: (java.lang.ClassNotFoundException) com.fasterxml.jackson.databind.deser.std.DateDeserializers$TimestampDeserializer 

getting this error while running via native image on lambda; in Local its running fine

Seems like while fetching a timestamp from Database(also in timestamp) its giving error.

graalvm:20.3.2 gradle: 7 java: 8

tried adding the following in the reflection.Json file

 {
        "name": "com.fasterxml.jackson.databind.deser.std.DateDeserializers",
        "allDeclaredConstructors": true,
        "allPublicConstructors": true,
        "allDeclaredMethods": true,
        "allPublicMethods": true,
        "allDeclaredClasses": true,
        "allPublicClasses": true,
        "allDeclaredFields": true
    },

tried adding in build.gradle

implementation group: 'com.fasterxml.jackson.core', name: 'jackson-databind', version: '2.14.1'

Answer 1

Your reflection config should be mentioning different class,

com.fasterxml.jackson.databind.deser.std.DateDeserializers$TimestampDeserializer

rather than

com.fasterxml.jackson.databind.deser.std.DateDeserializers
