我对Spring 2.5开发和java有一些了解,但我正在尝试更多地了解现代Spring,包括Boot和Data。我正在看这个项目:
https://github.com/spring-projects/spring-data-examples/tree/master/rest/multi-store
我有这个例子在我的机器上工作,但我想覆盖这个例子的某些方面。例如,我想指定我自己的mongo数据库服务器和要在项目中使用的名称。似乎要做的是创建一个指定mongo数据源的新bean,但我不确定在这种情况下如何做。
import com.mongodb.Mongo;
import com.mongodb.MongoClient;
import example.person.Person;
import example.person.PersonRepository;
import example.treasure.Treasure;

}
treasureRepository.deleteAll();
treasureRepository.save(new Treasure("Sting", "Made by the Elves"));
treasureRepository.save(new Treasure("Sauron's ring", "One ring to rule them all"));
for (Treasure treasure : treasureRepository.findAll()) {
log.info("Found treasure " + treasure.toString());

请参阅MongoRepositoriesAutoConfiguration,这是自动配置发生的地方。
您可以使用Spring Boot的属性机制覆盖属性:
http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-external-config.html
在您的情况下,只需创建一个包含要覆盖的属性的application.properties文件:例如。 spring.data.mongo.host =,某

实际属性位于我链接到http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html
的文档中马库斯提出了一个错字 - 它是spring.data.mongodb。*
我仍然不确定如何更改创建的数据库名称 - 默认似乎是" test" - 也许这是mongodb的默认设置?
