java - 未找到能够将 GeoCommand 转换为 DBObject 的转换器

Question

我无法在 spring data mongodb 中查询within的GeoSpatial Query，无论我编写自定义查询还是spring data接口(interface)查询，我都会收到此错误，并且相同的查询在 mongodb 客户端(robomongo)中工作正常:

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();

之后

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

创建MongoTemplate时
