Java – error creating bean named defaultservlethandlermapping
•
Java
I convert all XML spring configurations into Java code, but I can't run all the tests (they used before) because I have an ugly exception:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'defaultServletHandlerMapping' defined in class path resource

This is my test class:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes=ApplicationContextTest.class)
public class AccountServiceTest {
..
}
And my applicationcontexttest:
@Configuration
@EnableTransactionManagement
@PropertySource({ "classpath:databaseTest.properties" })
@ComponentScan(basePackages = { "org.example.springproject" })
public class ApplicationContextTest {
@Autowired
private Environment env;
@Bean(name = "dataSource")
public DataSource dataSource() {
return new EmbeddedDatabaseBuilder()
.setType(EmbeddedDatabaseType.Hsql)
.addScript("classpath:sql/schema.sql")
.addScript("classpath:sql/test-data.sql")
.build();
}
@Bean(name = "sessionFactory")
public LocalSessionfactorybean sessionFactory() {
LocalSessionfactorybean sessionFactory = new LocalSessionfactorybean();
sessionFactory.setDataSource(dataSource());
sessionFactory.setPackagesToScan(new String[] { "org.example.springproject.domains" });
sessionFactory.setHibernateProperties(hibernateProperties());
return sessionFactory;
}
@Bean(name = "transactionManager")
public HibernateTransactionManager transactionManager() {
HibernateTransactionManager txManager = new HibernateTransactionManager();
txManager.setSessionFactory(sessionFactory().getObject());
return txManager;
}
@SuppressWarnings("serial")
private Properties hibernateProperties() {
return new Properties() {
{
setProperty("hibernate.cache.provider_class",env.getProperty("hibernate.provider_class"));
setProperty("hibernate.show_sql",env.getProperty("hibernate.show_sql"));
setProperty("hibernate.hbm2ddl.auto",env.getProperty("hibernate.hbm2ddl"));
}
};
}
}
I tried to put @ webappconfiguration on my test class, but it didn't work The project is a spring MVC project, but now I'm testing the service layer, so why do I need to put this annotation in my class? Even with this comment, another error is coming So what's here?
Solution
Your configuration is normal except for one place
I will assume that there are other @ configurations in your package, which is selected by @ componentscan (delegatingwebmvcconfiguration in your exception, most likely imported by @ enablewebmvc somewhere in the external @ configuration)
A possible solution is to use filters in component scanning
