Description

See GitHub PR: https://github.com/apache/camel/pull/1033

Also upgrades to Jackson 2.x to allow injecting a custom ObjectMapper into SalesforceEndpointConfig, which in turn allows registering the Jdk8Module when using Java 1.8, which handles (de)serializing of Optional<?> in a reasonable manner. Jackson 1.x does not have the Jdk8Module.

Note that this requires that the project using the plugin is itself using Java 1.8+.

To use Jdk8Module, add this dependency:

		<dependency>
			<groupId>com.fasterxml.jackson.datatype</groupId>
			<artifactId>jackson-datatype-jdk8</artifactId>
		</dependency>

Then configure a custom ObjectMapper like the following snippet:

import org.apache.camel.component.salesforce.SalesforceEndpointConfig;
...
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.datatype.jdk8.Jdk8Module;
...
	@Bean
	public SalesforceEndpointConfig salesforceEndpointConfig() {
		SalesforceEndpointConfig salesforceEndpointConfig = new SalesforceEndpointConfig();
		...
		ObjectMapper objectMapper = new ObjectMapper();
		objectMapper.registerModule(new Jdk8Module());
		objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
		salesforceEndpointConfig.setObjectMapper(objectMapper);
		return salesforceEndpointConfig;
	}
