Please follow below steps to setup multiple mongodb data sources.
Define your primary and secondary mongodb properties like below in application.properties, please replace with them your db details:
######Primary Mongo DB########################
spring.data.mongodb.host=localhost
spring.data.mongodb.database=primary
spring.data.mongodb.port=27017
spring.data.mongodb.password=*******
spring.data.mongodb.username=*******
###########Secondary MongoDB#####################
mongodb.host=localhost
mongodb.port=27017
mongodb.database=secondary
mongodb.username=******
mongodb.password=******
Now add Multiple Mongo Db Configuration..
@Configuration
public class MultipleMongoConfig {
@Primary
@Bean(name = "primary")
@ConfigurationProperties(prefix = "spring.data.mongodb")
public MongoProperties getPrimary() {
return new MongoProperties();
}
@Bean(name = "secondary")
@ConfigurationProperties(prefix = "mongodb")
public MongoProperties getSecondary() {
return new MongoProperties();
}
@Primary
@Bean(name = "primaryMongoTemplate")
public MongoTemplate primaryMongoTemplate() throws Exception {
return new MongoTemplate(primaryFactory(getPrimary()));
}
@Bean(name = "secondaryMongoTemplate")
public MongoTemplate secondaryMongoTemplate() throws Exception {
return new MongoTemplate(secondaryFactory(getSecondary()));
}
@Bean
@Primary
public MongoDbFactory primaryFactory(final MongoProperties mongo) throws Exception {
return new SimpleMongoDbFactory(new MongoClient(mongo.getHost(), mongo.getPort()),
mongo.getDatabase());
}
@Bean
public MongoDbFactory secondaryFactory(final MongoProperties mongo) throws Exception {
return new SimpleMongoDbFactory(new MongoClient(mongo.getHost(), mongo.getPort()),
mongo.getDatabase());
}
}
Now enable EnableMongoRepositories for your primary an secondary.please make sure you change basePackages = "com.example.springbootmultipledatasource.primary.repository" your repository package here
@Configuration
@EnableMongoRepositories(basePackages =
"com.example.springbootmultipledatasource.primary.repository",
mongoTemplateRef = "primaryMongoTemplate")
public class PrimaryMongoConfig {
}
Secondary Mongo Template:Please make sure you change your secondary repository package here basePackages = "com.example.springbootmultipledatasource.secondary.repository
@Configuration
@EnableMongoRepositories(basePackages = "com.example.springbootmultipledatasource.secondary.repository",
mongoTemplateRef = "secondaryMongoTemplate")
public class SecondaryMongoConfig {
}
Now you can create your document, repository, service, controller and you are good to go.below is my project structure you can create or have different.
