Spring Boot多数据源配置（二）MongoDB

在Spring Boot多数据源配置（一）durid、mysql、jpa 整合中已经讲过了Spring Boot如何配置mysql多数据源。本篇文章讲一下Spring Boot如何配置mongoDB多数据源。

配置文件

spring:
#mongo配置
  data:
    mongodb:
      statis:
        database: kxlist_statis
        uri: 192.168.1.115:27017
      list:
        database: kxlist_list
        uri: 192.168.1.115:27017

JAVA文件：

• 总的配置：

@Configuration
public class MultipleMongoProperties {
    @Bean(name="statisMongoProperties")
    @Primary
    @ConfigurationProperties(prefix="spring.data.mongodb.statis")
    public MongoProperties statisMongoProperties() {
        System.out.println("-------------------- statisMongoProperties init ---------------------");
        return new MongoProperties();
    }

    @Bean(name="listMongoProperties")
    @ConfigurationProperties(prefix="spring.data.mongodb.list")
    public MongoProperties listMongoProperties() {
        System.out.println("-------------------- listMongoProperties init ---------------------");
        return new MongoProperties();
    }

}

• statis数据源配置

@Configuration
@EnableMongoRepositories(basePackages = "com.kxlist.statistics.domain.statis", mongoTemplateRef = "statisMongo")
public class StatisMongoMongoTemplate {
    @Autowired
    @Qualifier("statisMongoProperties")
    private MongoProperties mongoProperties;

    @Primary
    @Bean(name = "statisMongo")
    public MongoTemplate statisMongoTemplate() throws Exception {
        return new MongoTemplate(statisFactory(this.mongoProperties));
    }

    @Bean
    @Primary
    public MongoDbFactory statisFactory(MongoProperties mongoProperties) throws Exception {

        ServerAddress serverAdress = new ServerAddress(mongoProperties.getUri());

        return new SimpleMongoDbFactory(new MongoClient(serverAdress), mongoProperties.getDatabase());

    }
}

• list数据源配置
  
  和statis的配置很相似

@Configuration
@EnableMongoRepositories(basePackages = "com.kxlist.statistics.domain.list", mongoTemplateRef = "listMongo")
public class ListMongoTemplate {
    @Autowired
    @Qualifier("listMongoProperties")
    private MongoProperties mongoProperties;

    @Bean(name = "listMongo")
    public MongoTemplate listTemplate() throws Exception {
        return new MongoTemplate(listFactory(this.mongoProperties));
    }

    @Bean
    public MongoDbFactory listFactory(MongoProperties mongoProperties) throws Exception {

        ServerAddress serverAdress = new ServerAddress(mongoProperties.getUri());

        return new SimpleMongoDbFactory(new MongoClient(serverAdress), mongoProperties.getDatabase());

    }
}

在相应的包下建立实体类和Repository就可以了。
