我正在尝试使用 @EnableMongoRepositories 来使用两个单独的 mongo 存储库,例如:
@Configuration
@EnableMongoRepositories(mongoTemplateRef = "mongoBOTemplate", basePackages = "sandbox.dao.bo")
public class BOMongoConfig {
@Value("#{mongo.hostBO}")
private String hostBO;
@Value("#{mongo.databaseBO}")
private String databaseBO;
@Bean
public MongoDbFactory mongoBODbFactory() throws Exception {
return new SimpleMongoDbFactory(new MongoClient(hostBO), databaseBO);
}
@Bean
public MongoTemplate mongoBOTemplate() throws Exception {
return new MongoTemplate(mongoBODbFactory());
}
}
和
@Configuration
@EnableMongoRepositories(mongoTemplateRef = "mongoTemplate", basePackages = "sandbox.dao.sandbox")
public class SandboxMongoConfig {
@Value("#{mongo.host}")
private String host;
@Value("#{mongo.database}")
private String database;
@Bean
public MongoDbFactory mongoDbFactory() throws Exception {
return new SimpleMongoDbFactory(new MongoClient(host), database);
}
@Bean
public MongoTemplate mongoTemplate() throws Exception {
return new MongoTemplate(mongoDbFactory());
}
}
但我因为这个错误而感到困惑:

据我了解,只有一个选项可以修复它是使用@Profile。我正在使用 maven 进行配置文件管理,但不确定为什么我需要代码中的核心配置文件...
谁能帮我解决误解?谢谢。
