I have interfaces extends from MongoRepository. They are using default database of mongodb. I would like to define the database name for the classes.
public interface CustomerRepository extends MongoRepository<Customer, String> {
...
}
How can I define it?
You just need to define respective mongobd properties in application.properties file or if you want to yml syntax then define props in application.yml. Under src/main/resources, application.properties should be there already.
application.properties :
spring.data.mongodb.host=<hostname>
spring.data.mongodb.port=27017
spring.data.mongodb.database=<dbname>
spring.data.mongodb.username=<usernamr>
spring.data.mongodb.password=******
Or
application.yml :
spring:
data:
mongodb:
host: <hostname>
port: 27017
database: <dbname>
username: <usernamr>
password: ******
If you are using Spring Boot, the following steps might help you.
Define the following properties in application.properties or yml descriptor. note the properties should start with spring.data.mongodb. If you are using Mongo 3.x java driver, spring.data.mongodb.uri should be used to provide uri configurations.
spring.profiles: myprofile spring.data.mongodb.uri: mongodb://user:passwd@url:port/dbname spring.data.mongodb.database:myDB
Write SpringMongoConfiguration.
@Configuration
@EnableMongoRepostories("path.to.your.repository")
public class SpringMongoConfiguration extends AbstractMongoConfiguration {
@Value("${spring.data.mongodb.uri}")
private String mongoDB;
@Value("${spring.data.mongodb.uri}")
private String mongoURI;
@Override
protected String getDatabaseName() {
// TODO Auto-generated method stub
return mongoDB;
}
@Override
public MongoMappingContext mongoMappingContext()
throws ClassNotFoundException {
// TODO Auto-generated method stub
return super.mongoMappingContext();
}
@Override
@Bean
public Mongo mongo() throws Exception {
return new MongoClient(new MongoClientURI(myURI));
}
}
Build your project and run your spring boot app
java -jar -Dspring.profiles.active=myprofile your-app.jar
If you are using context XML add the following in your XML and define the database configurations.
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mongo="http://www.springframework.org/schema/data/mongo"
xsi:schemaLocation="http://www.springframework.org/schema/data/mongo http://www.springframework.org/schema/data/mongo/spring-mongo.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<mongo:mongo-client credentials="user:password@database" />
<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg name="mongo" ref="mongo"/>
<constructor-arg name="databaseName" value="myDBName"/>
</bean>
</beans>
Alternatively, Define a class by extending AbstractMongoConfiguration and override the getDatabaseName().
@Configuration
public class SpringDBConfig extends AbstractMongoConfiguration
{
@Override
protected String getDatabaseName() {
return "testdatabase";
}
......
}
spring-boot tag, so you can't suggest to configure a XML!
Documentname (table name) for classes?
