Question

我似乎在将具有java.time.LocalDateTime字段的数据库实体写入MongoDB表时遇到问题。我读过的所有内容似乎都表明这应该不是2014年末左右的问题，但由于某些原因，我仍然会遇到问题：

org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.time.LocalDateTime] to type [java.util.Date]

我有一个定制的MongoConfig，看起来像这样。我尝试将其删除，但这并不能解决问题，因此，这里的问题似乎不存在，但是这里是：

@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);
}

}

如果需要，我可以编写一个自定义转换器为我完成此操作，但是我阅读的所有文档都说此错误已在2014年11月前后修复，因此我想知道自己做错了什么。有任何想法吗？谢谢。
