Hello everybody,
I’m trying to use some examples from the External Task Client for Spring Boot.
https://docs.camunda.org/manual/latest/user-guide/ext-client/spring-boot-starter/#handler-configuration-example
I’m basically copy pasting the code and I’m getting an error that I cannot seem to figure out.
I added a handler as in the example and an error is popping. I’m using a spring boot java 11, the bpmn diagram was added to my camunda.
import org.camunda.bpm.client.spring.annotation.ExternalTaskSubscription;
import org.camunda.bpm.client.task.ExternalTaskHandler;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class HandlerConfiguration {
@Bean
@ExternalTaskSubscription(
topicName = "creditScoreChecker",
processDefinitionKey = "loan_process",
includeExtensionProperties = true,
variableNames = "defaultScore"
)
public ExternalTaskHandler creditScoreCheckerHandler() {
return (externalTask, externalTaskService) -> {
// add your business logic here
externalTaskService.complete(externalTask);
};
}
@Bean
@ExternalTaskSubscription(
topicName = "loanGranter",
processDefinitionKey = "loan_process",
includeExtensionProperties = true,
variableNames = "defaultScore"
)
public ExternalTaskHandler loanGranterHandler() {
return (externalTask, externalTaskService) -> {
// add your business logic here
externalTaskService.complete(externalTask);
};
}
}
Error:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean
with name 'creditScoreCheckerHandlerSubscription': Unsatisfied dependency expressed
through field 'client'; nested exception is org.springframework.beans.factory.BeanCreationException:
