springTestContextPrepareTestInstance failed in spring-test - spring

Question

I try to setup a project with spring-test using TestNg in Maven. The code is like:
#ContextConfiguration(classes={WebMvcTestConfig.class})
public class MyResourceParserTest extends AbstractTestNGSpringContextTests {
#BeforeMethod
public void setup() throws Exception {
}
A WebMvcTestConfig class simply defined a bean:
#Configuration
#ComponentScan(basePackages={"com.test.myapp.model"})
#EnableTransactionManagement
public class WebMvcTestConfig {
private static final String relativeConfigURI = "\\MyAppSpringConfig\\";
private static final String userHomeURI = System.getProperty("user.home");
private static final String jdbcPropertiesFileName = "jdbc.properties";
private static final String hibernatePropertiesFileName = "hibernate.properties";
#Bean
public PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer = new PropertySourcesPlaceholderConfigurer();
propertySourcesPlaceholderConfigurer.setLocation(new FileSystemResource(userHomeURI + relativeConfigURI + jdbcPropertiesFileName));
return propertySourcesPlaceholderConfigurer;
}
#Bean
public DataSource dataSource(
#Value("${jdbc.driverClassName}") String driverClass,
#Value("${jdbc.url}") String jdbcUrl,
#Value("${jdbc.username}") String username,
#Value("${jdbc.password}") String password) {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(driverClass);
dataSource.setUrl(jdbcUrl);
dataSource.setUsername(username);
dataSource.setPassword(password);
return dataSource;
}
#Bean
public LocalSessionFactoryBean localSessionFactoryBean() {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(dataSource("", "", "", ""));
sessionFactory.setPackagesToScan("com.test.myapp.model.domain");
sessionFactory.setHibernateProperties(hibernateProperties());
return sessionFactory;
}
#Bean
public Properties hibernateProperties() {
Properties hibernateProperties = new Properties();
try {
hibernateProperties.load(new FileInputStream(userHomeURI + relativeConfigURI + hibernatePropertiesFileName));
} catch (FileNotFoundException e) {
e.printStackTrace();
return null;
} catch (IOException e) {
e.printStackTrace();
return null;
}
return hibernateProperties;
}
#Bean
public PlatformTransactionManager platformTransactionManager() {
return new HibernateTransactionManager(localSessionFactoryBean().getObject());
}
}
I got error for Failed to load ApplicationContext when running mvn test from command line:
java.lang.IllegalStateException: Failed to load ApplicationContext
Can you help me?

3 things I notice from your configuration.
Your loading of configuration files is strange, use Spring for that instead of rolling your own. Simply use #PropertySource for that.
The propertySourcesPlaceholderConfigurer() must be static
Your call to datasource will lead to an invalid datasource configuration.
Try the following configuration class.
#Configuration
#ComponentScan(basePackages={"com.test.myapp.model"})
#EnableTransactionManagement
#PropertySource({"${user.home}/MyAppSpringConfig/jdbc.properties","${user.home}/MyAppSpringConfig/hibernate.properties"}
public class WebMvcTestConfig {
#Autowired
private Environment env;
#Bean
public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
return new new PropertySourcesPlaceholderConfigurer();
}
#Bean
public DataSource dataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(env.getRequiredProperty("jdbc.driverClassName"));
dataSource.setUrl(env.getRequiredProperty("jdbc.url"));
dataSource.setUsername(env.getProperty("env.username", ""));
dataSource.setPassword(env.getProperty("env.password", ""));
return dataSource;
}
#Bean
public LocalSessionFactoryBean localSessionFactoryBean() {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(dataSource());
sessionFactory.setPackagesToScan("com.test.myapp.model.domain");
sessionFactory.setHibernateProperties(hibernateProperties());
return sessionFactory;
}
#Bean
public Properties hibernateProperties() {
Properties hibernateProperties = new Properties();
hibernateProperties.setProperty("hibernate.dialect", env.getProperty("hibernate.dialect"));
// Other properties
return hibernateProperties;
}
#Bean
public PlatformTransactionManager platformTransactionManager() {
return new HibernateTransactionManager(localSessionFactoryBean().getObject());
}
}
