Question

我的应用程序使用在不同实例上托管的具有相同集合（不同数据）的两个mongo模式。我有一个用于领域事物的ThingsRepository。

public class Thing {
  private String id;
  private String name;
  private String type;
  // etc...  
}

public interface ThingRepository extends MongoRepository<Thing, String>, ThingRepositoryCustom {
    Thing save(Thing Thing);
}

public class ThingRepositoryCustomImpl implements ThingRepositoryCustom {
  ...
}

我的应用程序已连接到ThingsRepository中，并从其中一个模式随机地连接了存储库。我想注入一个可以返回的工厂，并使用该工厂通过schema1 / schema2来获取仓库。我遇到了Customizing Spring Data repository bean names for use with multiple data sources，该解决方案为每个架构的每个存储库实例定义了bean，我有很多集合，并探讨是否有更好的方法。感谢您提供任何反馈意见。

这是Spring bean的配置

<!-- for schema1 -->
<mongo:mongo-client id="mongo1" replica-set="${mongodb.replication.set.1}" credentials="${MONGO_USER_1}@${mongodb.dbname.1}" >
  <mongo:client-options max-connection-idle-time="${mongodb.max.connection.idle.1:300000}" />
</mongo:mongo-client>

<mongo:db-factory id="mongoDbFactory1" dbname="${mongodb.dbname.1}" mongo-ref="mongo1" />

<bean id="mongoTemplate1" class="org.springframework.data.mongodb.core.MongoTemplate">
  <constructor-arg ref="mongoDbFactory1" />
  <constructor-arg ref="mongoConverter1" />
</bean>

<bean id="mongoConverter1" class="org.springframework.data.mongodb.core.convert.MappingMongoConverter">
  <constructor-arg ref="mongoDbFactory1" />
  <constructor-arg>
    <bean class="org.springframework.data.mongodb.core.mapping.MongoMappingContext" />
  </constructor-arg>
  <property name="mapKeyDotReplacement" value="%2E" />
</bean>

<mongo:repositories base-package="com.xyz.pkg" repository-impl-postfix="CustomImpl" mongo-template-ref="mongoTemplate1" />


<!-- for schema2 -->
<mongo:mongo-client id="mongo2" replica-set="${mongodb.replication.set.2}" credentials="${MONGO_USER_2}@${mongodb.dbname.2}" >
  <mongo:client-options max-connection-idle-time="${mongodb.max.connection.idle.2:300000}" />
</mongo:mongo-client>

<mongo:db-factory id="mongoDbFactory2" dbname="${mongodb.dbname.2}" mongo-ref="mongo2" />

<bean id="mongoTemplate2" class="org.springframework.data.mongodb.core.MongoTemplate">
  <constructor-arg ref="mongoDbFactory2" />
  <constructor-arg ref="mongoConverter2" />
</bean>

<bean id="mongoConverter2" class="org.springframework.data.mongodb.core.convert.MappingMongoConverter">
  <constructor-arg ref="mongoDbFactory2" />
  <constructor-arg>
    <bean class="org.springframework.data.mongodb.core.mapping.MongoMappingContext" />
  </constructor-arg>
  <property name="mapKeyDotReplacement" value="%2E" />
</bean>

<mongo:repositories base-package="com.xyz.pkg" repository-impl-postfix="CustomImpl" mongo-template-ref="mongoTemplate2" />
