Failed to load ApplicationContext - spring

Question

Currently I'm setting-up a Spring MVC + Hibernate + Maven Web Application.
Im stack with a JUnit error forbidding the run of my application with tomcat
Here is the JUnit failure trace :

For test I have two classes. The first one is : BaseTestConfig.java :
#Configuration
#ComponentScan("com.mycompany.webAppDemo")
#EnableWebMvc
public class BaseTestConfig {
#Bean
public UrlBasedViewResolver setupViewResolver() {
UrlBasedViewResolver resolver = new UrlBasedViewResolver();
resolver.setPrefix("/WEB-INF/pages/");
resolver.setSuffix(".jsp");
resolver.setViewClass(JstlView.class);
return resolver;
}
}
The second one is LinkControllerClasses.java :
#RunWith(SpringJUnit4ClassRunner.class)
#WebAppConfiguration
#ContextConfiguration(classes=BaseTestConfig.class)
public class LinkControllerTest {
#Autowired
private WebApplicationContext wac;
private MockMvc mockMvc;
#Before
public void init() {
mockMvc = MockMvcBuilders.webAppContextSetup(wac).build();
}
#Test
public void testHomePage() throws Exception {
mockMvc.perform(get("/"))
.andExpect(status().isOk())
.andExpect(view().name("home"));
}
#Test
public void testIndexPage() throws Exception {
mockMvc.perform(get("/index.html"))
.andExpect(status().isOk())
.andExpect(view().name("home"));
}
}
For my application configuration I have two classes :
Initializer.java
public class Initializer implements WebApplicationInitializer{
#Override
public void onStartup(ServletContext servletContext) throws ServletException {
// TODO Auto-generated method stub
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(WebAppConfig.class);
servletContext.addListener(new ContextLoaderListener(ctx));
ctx.setServletContext(servletContext);
Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx));
servlet.addMapping("/");
servlet.setLoadOnStartup(1);
}
}
And WebAppConfig.java :
#Configuration
#ComponentScan("com.mycompany.webAppDemo")
#EnableWebMvc
#EnableTransactionManagement
#PropertySource("classpath:application.properties")
public class WebAppConfig {
private static final String PROPERTY_NAME_DATABASE_DRIVER = "com.mysql.jdbc.Driver";
private static final String PROPERTY_NAME_DATABASE_PASSWORD = "";
private static final String PROPERTY_NAME_DATABASE_URL = "jdbc:mysql://127.0.0.1:3306/demodb";
private static final String PROPERTY_NAME_DATABASE_USERNAME = "root";
private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "org.hibernate.dialect.MySQL5InnoDBDialect";
private static final String PROPERTY_NAME_HIBERNATE_SHOW_SQL = "true";
private static final String PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN = "com.amadeus.webAppDemo.model";
#Resource
private Environment env;
#Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(env.getRequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));
dataSource.setUrl(env.getRequiredProperty(PROPERTY_NAME_DATABASE_URL));
dataSource.setUsername(env.getRequiredProperty(PROPERTY_NAME_DATABASE_USERNAME));
dataSource.setPassword(env.getRequiredProperty(PROPERTY_NAME_DATABASE_PASSWORD));
return dataSource;
}
#Bean
public LocalSessionFactoryBean sessionFactory() {
LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
sessionFactoryBean.setDataSource(dataSource());
sessionFactoryBean.setPackagesToScan(env.getRequiredProperty(PROPERTY_NAME_ENTITYMANAGER_PACKAGES_TO_SCAN));
sessionFactoryBean.setHibernateProperties(hibProperties());
return sessionFactoryBean;
}
private Properties hibProperties() {
Properties properties = new Properties();
properties.put(PROPERTY_NAME_HIBERNATE_DIALECT, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT));
properties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, env.getRequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));
return properties;
}
#Bean
public HibernateTransactionManager transactionManager() {
HibernateTransactionManager transactionManager = new HibernateTransactionManager();
transactionManager.setSessionFactory(sessionFactory().getObject());
return transactionManager;
}
#Bean
public UrlBasedViewResolver setupViewResolver() {
UrlBasedViewResolver resolver = new UrlBasedViewResolver();
resolver.setPrefix("/WEB-INF/pages/");
resolver.setSuffix(".jsp");
resolver.setViewClass(JstlView.class);
return resolver;
}
}
Finaly here is the two controller classes :
LinkControl.java
#Controller
public class LinkController {
#RequestMapping(value="/")
public ModelAndView mainPage() {
return new ModelAndView("home");
}
#RequestMapping(value="/index")
public ModelAndView indexPage() {
return new ModelAndView("home");
}
}
TeamController.java
#Controller
public class TeamController {
#Autowired
private TeamService teamService;
#RequestMapping(value="/team/add")
public ModelAndView addTeamPage(){
ModelAndView modelAndView = new ModelAndView("add-team-form");
modelAndView.addObject("team", new Team());
return modelAndView;
}
#RequestMapping(value="/team/add/process")
public ModelAndView addingTeam(#ModelAttribute Team team){
ModelAndView modelAndView = new ModelAndView("home");
teamService.addTeam(team);
String message ="Team was successfully added";
modelAndView.addObject("message", message);
return modelAndView;
}
#RequestMapping(value="/team/list")
public ModelAndView listOfTeams() {
ModelAndView modelAndView = new ModelAndView("list-of-teams");
List<Team> teams = teamService.getTeams();
modelAndView.addObject("teams", teams);
return modelAndView;
}
#RequestMapping(value="/team/edit/{id}", method=RequestMethod.GET)
public ModelAndView editTeamPage(#PathVariable Integer id) {
ModelAndView modelAndView = new ModelAndView("edit-team-form");
Team team = teamService.getTeam(id);
modelAndView.addObject("team",team);
return modelAndView;
}
#RequestMapping(value="/team/edit/{id}", method=RequestMethod.POST)
public ModelAndView edditingTeam(#ModelAttribute Team team, #PathVariable Integer id) {
ModelAndView modelAndView = new ModelAndView("home");
teamService.updateTeam(team);
String message = "Team was successfully edited.";
modelAndView.addObject("message", message);
return modelAndView;
}
#RequestMapping(value="/team/delete/{id}", method=RequestMethod.GET)
public ModelAndView deleteTeam(#PathVariable Integer id) {
ModelAndView modelAndView = new ModelAndView("home");
teamService.deleteTeam(id);
String message = "Team was successfully deleted.";
modelAndView.addObject("message", message);
return modelAndView;
}
}
I tried the suggested modification of a similar issue
Failed to load ApplicationContext with #ContextConfiguration(classes={ ... })
But it is not working :(
Thank you for your answer here is the application.properties
#DB properties:
db.driver=com.mysql.jdbc.Driver
db.url=jdbc:mysql://localhost:3306/demodb
db.username=root
db.password=*****
#Hibernate Configuration:
hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
hibernate.show_sql=true
entitymanager.packages.to.scan=com.mycompany.webAppDemo.model
I made some change in my WebAppConfig.java.For eg.instead of :
private static final String PROPERTY_NAME_DATABASE_DRIVER = "com.mysql.jdbc.Driver";
I do this :
private static final String PROPERTY_NAME_DATABASE_DRIVER = "db.driver";
But still having the same error :(

Answer 1

Spring's Environment class' getRequiredProperty() method throws an IllegalStateException if it cannot resolve the property. You are tring to do this:
dataSource.setDriverClassName(env.getRequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));
which tries to get the property with the key
private static final String PROPERTY_NAME_DATABASE_DRIVER = "com.mysql.jdbc.Driver";
That doesn't make any sense unless your property file has an entry:
com.mysql.jdbc.Driver=com.mysql.jdbc.Driver
I think what you want is either:
private static final String PROPERTY_NAME_DATABASE_DRIVER = "driverClassName";
// in properties file
...
driverClassName=com.mysql.jdbc.Driver
...
or
dataSource.setDriverClassName(PROPERTY_NAME_DATABASE_DRIVER);
to set it directly instead of through properties file.
I would ask you to post the contents of your application.properties file if you want more details.
