没有找到能够将GeoCommand转换为DBObject的转换器

Question

我无法在spring数据mongodb中查询GeoSpatial Query within，无论是编写自定义查询还是弹簧数据接口查询我都收到此错误，同样的查询在mongodb中工作正常客户端（robomongo）：

以下是查询：

distanceRepository.findDistanceBySrcWithin(srcCircle);

以下是mongo配置：

@Override
public MongoClient mongo() throws Exception {
List<MongoCredential> mongoCredentials = new ArrayList<>();
mongoCredentials.add(MongoCredential.createCredential(userName, "admin", password.toCharArray()));
return new MongoClient(new ServerAddress(host, port), mongoCredentials);
}

@Override
@Bean
public MongoTemplate mongoTemplate() throws Exception {
MultiTenantMongoDbFactory mongoDbFactory = (MultiTenantMongoDbFactory) mongoDbFactory();

MongoTypeMapper typeMapper = new DefaultMongoTypeMapper(null);
MappingMongoConverter converter = new MappingMongoConverter(mongoDbFactory(), new MongoMappingContext());
converter.setTypeMapper(typeMapper);

MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory, converter);
mongoDbFactory.setMongoTemplate(mongoTemplate);
return mongoTemplate;
}

@Override
@Bean
public MongoDbFactory mongoDbFactory() throws Exception {
return new MultiTenantMongoDbFactory(mongo(), dbName);
}

以下是堆栈跟踪：

Answer 1

关键是添加以下行：

converter.afterPropertiesSet();

后

MappingMongoConverter converter = new MappingMongoConverter(mongoDbFactory(), 
new MongoMappingContext());
converter.setTypeMapper(typeMapper);

创建MongoTemplate

时
