spring-boot + spring-data-mongo 如何配置多数据源 ?

Question

请问有类似的案例吗 ? xml配置方式就不要了 。

Answer 1

先写两个MongoTemplate:

@Bean(autowire = Autowire.BY_NAME, name = "firstMongoTemplate")
public MongoTemplate firstMongoTemplate() throws Exception {
    return new MongoTemplate(new MongoClient("1.1.1.1", 27017,database);
}

@Bean(autowire = Autowire.BY_NAME, name = "secondMongoTemplate")
public MongoTemplate secondMongoTemplate() throws Exception {
    return new MongoTemplate(new MongoClient("2.2.2.2", 27017,database);
}

再写两个Configuration：

@Configuration
@EnableMongoRepositories(basePackages = "com.whatever.repositories.first", mongoTemplateRef = "firstMongoTemplate")
public class FirstMongoConfig {
    ....
}

@Configuration
@EnableMongoRepositories(basePackages = "com.whatever.repositories.secondary", mongoTemplateRef = "secondMongoTemplate")
public class SecondMongoConfig {
    ....
}

然后怎么做你应该懂了
