Controller:

@Controller
@RequestMapping("/tests")
public class TestController {

@Autowired
TestService testService;

@RequestMapping("/testslist.json")
public @ResponseBody List<Test> getTestList() {
    return testService.getTests();
}

@RequestMapping("/layout")
public String getTestPartialPage(ModelMap modelMap) {
    return "tests/layout";
}
}

Model:

@Entity
@Table(name = "test") 
public class Test{
@Id
@GeneratedValue
@Column(name = "id")
private int id;

@Column(name = "name")
private String name;

///gettters and setters
}

Impl:

@Repository
public class TestDAOImpl implements TestDAO {

@Autowired
private SessionFactory sessionFactory;

public TestDAOImpl() {
}

public TestDAOImpl(SessionFactory sessionFactory) {
    this.sessionFactory = sessionFactory;
}

@Override
@Transactional
public List<Test> getTests() {
    @SuppressWarnings("unchecked")
    List<Test> tests = (List<Test>) sessionFactory.getCurrentSession()
            .createCriteria(Test.class)
            .setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY).list();
    return tests;
}
}

Angular Controller:

var TestsController = function($scope, $http) {
$scope.test = {};
$scope.editMode = false;

$scope.fetchTestList = function() {
    $http.get('tests/testslist.json').success(function(testList){
        $scope.tests = testList;
    });
};

$scope.resetTestForm = function() {
    $scope.resetError();
    $scope.test = {};
    $scope.editMode = false;
};

$scope.resetError = function() {
    $scope.error = false;
    $scope.errorMessage = '';
};

$scope.setError = function(message) {
    $scope.error = true;
    $scope.errorMessage = message;
};

$scope.fetchTestList()();

$scope.predicate = 'id';
};

Hibernate config:

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>        
<session-factory>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="show_sql">true</property> 

<mapping class="com.packt.app.model.Test"/>   
 </session-factory>
</hibernate-configuration>

Application runs without error, even when MySql Server off. In html view show me that list count "getTests" is 0. It looks like application not connection with MySQL Server. Whats wrong? Please help me.
