如何使用spring mongodb将WriteConcern设置为已确认？

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

spring.data.mongodb.uri=mongodb://localhost:27017/mydatabase

@Configuration
public class MongoConfig {

    @Bean
    public MongoTemplate mongoTemplate(MongoDbFactory mongoDbFactory, MappingMongoConverter mappingMongoConverter) {
        MongoTemplate mongoTemplate = new MongoTemplate(mongoDbFactory, mappingMongoConverter);
        mongoTemplate.setWriteConcern(WriteConcern.ACKNOWLEDGED);
        return mongoTemplate;
    }
}

@Service
public class MyService {

    private final MongoTemplate mongoTemplate;

    public MyService(MongoTemplate mongoTemplate) {
        this.mongoTemplate = mongoTemplate;
    }

    public void saveData(MyData data) {
        mongoTemplate.save(data);
    }
}
