How to provide more than one trusted package to deserialization in .yml?

When I am creating consumer and trying to deserialize object I got error

Caused by: IllegalArgumentException: The class 'com.domain.project2.package2.SomeEvent' is not in the trusted packages: [java.util, java.lang, com.domain.project2.package1, com.domain.project2.package2]. If you belive this class is....

My .yml config:

spring:
  kafka:
    bootstrap-servers: localhost:9092
    producer:
      key-serializer: org.apache.kafka.common.serialization.StringSerializer
      value-serializer: org.apache.kafka.support.serializer.JsonSerializer
    consumer:
      key-deserializer: org.apache.kafka.common.serialization.StringDeserializer
      value-deserializer: org.apache.kafka.support.serializer.JsonDeserializer
    properties:
      spring:
        json:
          trusted:
            packages: 'com.domain.project2.package1, com.domain.project2.package2'

I presume you mean 

spring:
  kafka:
    bootstrap-servers: localhost:9092
    producer:
      key-serializer: org.apache.kafka.common.serialization.StringSerializer
      value-serializer: org.springframework.kafka.support.serializer.JsonSerializer
    consumer:
      key-deserializer: org.apache.kafka.common.serialization.StringDeserializer
      value-deserializer: org.springframework.kafka.support.serializer.JsonDeserializer
    properties:
      spring:
        json:
          trusted:
            packages: 'com.domain.project2.package1, com.domain.project2.package2'

Since you are using the Spring deserializer, not the apache JsonDeserializer.

The problem is the space after the comma.

Use 'com.domain.project2.package1,com.domain.project2.package2'.

We should probably trim the packages to remove extraneous spaces.
