Examples with Datastore org.mongodb.morphia.Datastore used on opensource projects

Example 1 with Datastore

use of org.mongodb.morphia.Datastore in project morphia by mongodb.

the class Employee method main.

public static void main(final String[] args) throws UnknownHostException {
    final Morphia morphia = new Morphia();
    // tell morphia where to find your classes
    // can be called multiple times with different packages or classes
    morphia.mapPackage("org.mongodb.morphia.example");
    // create the Datastore connecting to the database running on the default port on the local host
    final Datastore datastore = morphia.createDatastore(new MongoClient(), "morphia_example");
    datastore.getDB().dropDatabase();
    datastore.ensureIndexes();
    final Employee elmer = new Employee("Elmer Fudd", 50000.0);
    datastore.save(elmer);
    final Employee daffy = new Employee("Daffy Duck", 40000.0);
    datastore.save(daffy);
    final Employee pepe = new Employee("Pepé Le Pew", 25000.0);
    datastore.save(pepe);
    elmer.getDirectReports().add(daffy);
    elmer.getDirectReports().add(pepe);
    datastore.save(elmer);
    Query<Employee> query = datastore.find(Employee.class);
    final List<Employee> employees = query.asList();
    Assert.assertEquals(3, employees.size());
    List<Employee> underpaid = datastore.find(Employee.class).filter("salary <=", 30000).asList();
    Assert.assertEquals(1, underpaid.size());
    underpaid = datastore.find(Employee.class).field("salary").lessThanOrEq(30000).asList();
    Assert.assertEquals(1, underpaid.size());
    final Query<Employee> underPaidQuery = datastore.find(Employee.class).filter("salary <=", 30000);
    final UpdateOperations<Employee> updateOperations = datastore.createUpdateOperations(Employee.class).inc("salary", 10000);
    final UpdateResults results = datastore.update(underPaidQuery, updateOperations);
    Assert.assertEquals(1, results.getUpdatedCount());
    final Query<Employee> overPaidQuery = datastore.find(Employee.class).filter("salary >", 100000);
    datastore.delete(overPaidQuery);
}
