Spring Mongo Integration

Setting up and using MongoDB in the Spring application is a simple two step process.Specify the Mongo template in the application configuration , then customize the ApplicationConfig . Step 1 Include the Mongo configuration in the application context

<mongo:db-factory id="mongoDbFactory" dbname="my-store" />
 
 <mongo:mapping-converter id="mongoConverter" base-package="springdata.mongodb">
  <mongo:custom-converters base-package="springdata.mongodb" />
 </mongo:mapping-converter>
 
 <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
  <constructor-arg ref="mongoDbFactory" />
  <constructor-arg ref="mongoConverter" />
  <property name="writeConcern" value="SAFE" />
 </bean>
 
 <mongo:repositories base-package="springdata.mongodb" />
Step2 Setup the ApplicationConfig in the base-package
@ComponentScan
@EnableMongoRepositories
class ApplicationConfig extends AbstractMongoConfiguration {

 
 @Override
 protected String getDatabaseName() {
 return "my-store";
 
 }

 
 @Override
 public Mongo mongo() throws Exception {

  Mongo mongo = new Mongo();
  mongo.setWriteConcern(WriteConcern.SAFE);

  return mongo;
 }

}
After the two steps the Mongo can be included in the application by simply autowiring
@Autowired Mongo mongo;
