Logstash logback encoder failing with java.util.ServiceConfigurationError (jackson.datatype.jsr310.JavaTimeModule could not be instantiated)

I am trying to have JSON-based logging in my springbootapp (2.4.8). I have followed instructions as mentioned in github and some other docs and StackOverflow-related questions. However, I am unable to resolve the issue.

Below is the exeption am getting:

ERROR in net.logstash.logback.encoder.LogstashEncoder@4fcee388 - Error occurred while dynamically loading jackson modules java.util.ServiceConfigurationError: com.fasterxml.jackson.databind.Module: Provider com.fasterxml.jackson.datatype.jsr310.JavaTimeModule could not be instantiated

I did make sure logstash-logback-encoder dependency was added and logback dependencies are >= 1.2.0 (am using 1.2.3). Please see excerpt from dependency tree for details.

[INFO] --- maven-dependency-plugin:3.1.2:tree (default-cli) @ <my-spring-boot-app> --

And please see corresponding src/main/resources/logback.xml:

<configuration>
    <appender name="consoleAppender" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="net.logstash.logback.encoder.LogstashEncoder"/>
    </appender>
    <logger name="jsonLogger" additivity="false" level="DEBUG">
        <appender-ref ref="consoleAppender"/>
    </logger>
    <root level="INFO">
        <appender-ref ref="consoleAppender"/>
    </root>
</configuration>

Following is the runtime exception am getting:

   ERROR in net.logstash.logback.encoder.LogstashEncoder@4fcee388 - Error occurred while dynamically loading jackson modules java.util.ServiceConfigurationError: com.fasterxml.jackson.databind.Module: Provider com.fasterxml.jackson.datatype.jsr310.JavaTimeModule could not be instantiated

Solution

  • I think I figured it out. It turned out to be a dependencies issue.

    (Basically, with logstash 6.6, jackson.core 2.9.3 threw above error. When i moved to 2.12.1 things started working. Below is actual details of the versions am using - excerpt from dependency tree)
