Chapter 15 ■ Spring Data Within Your Spring Application @Autowired DocumentDAO mongoDocumentDAO; @Autowired TypeDAO mongoTypeDAO; @Autowired DocumentService documentFacade; @Autowired TypeService typeFacade; @Test public void testMongoDBMigration(){ log.debug("Testing Spring Data MongoDB - Migration (Run only once)..."); assertNotNull(mongoDocumentDAO); assertNotNull(documentFacade); assertNotNull(typeFacade); assertNotNull(mongoTypeDAO); List types = typeFacade.getAllDefinedTypes(); assertNotNull(types); assertEquals(4, types.size()); for(Type type: types){ mongoTypeDAO.save(type); } List documents = documentFacade.getAllDocuments(); assertNotNull(documents); assertEquals(6, documents.size()); } } for(Document document : documents){ mongoDocumentDAO.save(document.getDocumentId(), document); } Reviewing the logic in your unit test (see Listing 15-6), you are going to start by migrating the JDBC into the MongoDB server; here you are using the two implementations of the DocumentDAO interface. And you are going to begin by adding the types that should be in the types collection, and then the documents that should be in the docs collection. After running the unit test you can open a new terminal (DOS or Unix) and connect to the MongoDB server to see if the data is there. Figure 15-1 shows the databases and the collections created. 211
Chapter 15 ■ Spring Data Within Your Spring Application Figure 15-1. MongoDB Shell Shows the mydocuments Database and the Two Collections, Docs and Types Figure 15-1 shows the invocation of the MongoDB server with the command mongo. This command will enter into the MongoDB shell, and by default the MongoDB server will set the test database as a default. To list the available databases, use the show dbs command. In your case, you should have the mydocuments database. To switch to the mydocuments database, use the use mydocuments command. Then you can see the collection that belongs to the database with the show collections command; you should see the docs and the types collections. Figures 15-2 and 15-3 show the results of the unit test. 212
