<mongo:mapping-converter> can't be configured as nested bean definition [DATAMONGO-892]

[spring-projects-issues]

Artem Bilan opened DATAMONGO-892 and commented

The sample config which worked in the 1.1.1 version, but doesn't work now:

<beans:bean id="messageStore" class="org.springframework.integration.mongodb.store.ConfigurableMongoDbMessageStore">
		<beans:constructor-arg ref="mongoDbFactory"/>
		<beans:constructor-arg>
			<mongo:mapping-converter>
				<mongo:custom-converters>
					<mongo:converter>
						<beans:bean class="org.springframework.integration.mongodb.store.ConfigurableMongoDbMessageGroupStoreTests$MessageReadConverter"/>
					</mongo:converter>
				</mongo:custom-converters>
			</mongo:mapping-converter>
		</beans:constructor-arg>
		<beans:constructor-arg value="testConfigurableMongoDbMessageStore"/>
	</beans:bean>

That's because MappingMongoConverterParser doesn't check if the parserContext.isNested(), registers BeanDefinition and returns null

As we discussed privately, the issue can be "Won't Fix" as it isn't recommended to use <mongo:mapping-converter> as nested bean definition, just as root one

The error message currently thrown is misleading. We'll make sure the error gives a hint to the problem
