I appear to be having a problem writing a DB entity with a java.time.LocalDateTime field to a MongoDB table. Everything I've read seems to say that this should not be a problem circa end-of-2014, but I'm still getting it for some reason:
org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.time.LocalDateTime] to type [java.util.Date]

I have a custom MongoConfig which looks like this. I tried removing it but that didn't fix the problem, so the problem doesn't seem to be anything here, but nevertheless here it is:
@Configuration
public class MongoConfig {
@Value("${spring.data.mongodb.database}")
private String database;
@Autowired
private MongoDbFactory mongoDbFactory;
public @Bean
MongoDbFactory mongoDBFactory() {
return new SimpleMongoDbFactory(new MongoClient(), database);
}
@Bean
public MongoTemplate mongoTemplate() {
DbRefResolver dbRefResolver = new DefaultDbRefResolver(mongoDbFactory);
// Remove _class
MappingMongoConverter converter = new MappingMongoConverter(dbRefResolver, new MongoMappingContext());
converter.setTypeMapper(new DefaultMongoTypeMapper(null));
return new MongoTemplate(mongoDBFactory(), converter);
}
}
I could write a custom converter to do this for me if I need to, but all the documentation I've read says this bug was fixed around November 2014 so I'm wondering what I've done wrong. Any ideas? Thanks.
