Mongodb and spring Integration

Here we use a project integrating mongodb in spring-data. First, add the dependency on it in maven. Here we use version 1.0.0.M5.

1. <! -- Mongodb spring -->
2. <Dependency>
3. <GroupId>Org. springframework. data</GroupId>
4. <ArtifactId>Spring-data-mongodb</ArtifactId>
5. <Version>1.0.0.M5</Version>
6. </Dependency>

Then the configuration file

1. <?Xml Version="1.0" Encoding=UTF-8"?>
2. <Beans Xmlns=Http://www.springframework.org/schema/beans"
3. Xmlns: xsi=Http://www.w3.org/2001/XMLSchema-instance" Xmlns: context=Http://www.springframework.org/schema/context"
4. Xmlns: mongo=Http://www.springframework.org/schema/data/mongo"
5. Xsi: schemaLocation= "Http://www.springframework.org/schema/context
6. Http://www.springframework.org/schema/context/spring-context-3.0.xsd
7. Http://www.springframework.org/schema/data/mongo
8. Http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd
9. Http://www.springframework.org/schema/beans

14. <Mongo: mongo Id="Mongo" Replica-set="Localhost: 27017">

24. Slave-OK="$ {Mongo. slaveOk }"
25. Write-number="1"
26. Write-timeout="0"
27. Write-fsync="True"/>
28. </Mongo: mongo>
30. <! -- Mongo factory, which is used to obtain the mongo instance. dbname is the name of the mongodb database. If not, it will be automatically created. -->
31. <Mongo: db-factory Dbname="Test" Mongo-ref="Mongo"/>
33. <! -- The primary operation object of mongodb. All operations for adding, deleting, modifying, and querying mongodb are completed through it -->
34. <Bean Id="Template" Class="Org. springframework. data. mongodb. core. Elastic template">
35. <Constructor-arg Name="MongoDbFactory" Ref="MongoDbFactory"/>
36. </Bean>
38. <! -- Ing converter: scan the files in the back-package directory and use them as a collection ing of mongodb according to the annotations -->
39. <Mongo: mapping-converter Base-package="Com. xxx. xxx. domain" />
41. <! -- The repository directory of mongodb bean automatically scans the interface that extends the MongoRepository interface for injection. -->
42. <Mongo: repositories Base-package="Com. xxx. xxx. persist. mongodb"/>
44. <! -- To translate any exceptions thrown in @ Repository annotated classes -->
45. <Context: annotation-config />
47. </Beans>

In this way, the basic configuration is complete, and other in-depth operations will be described in subsequent articles.
