Spring Maven JUnit NoClassDefFoundError:org/springframework/context /ApplicationContextException

Question

I have created a spring legacy project using Spring STS and xml configuration file spring-context.xml. I am trying to test my DAO class using JUnit (Run as > Maven test) but I get the following error:

initializationError(net.mozaikdev.samples.dao.test.AddressDAOTest)  Time elapsed: 0.006 sec  <<< ERROR!

I don't understand why I'm getting this exception since I have declared in my pom.xml the dependency to spring-context:

Here is my JUnit test:

@Autowired

private static final String STREET_1 = "street_1";

@Test

    Address address = new Address();
    address.setStreet_1(STREET_1);
    address.setStreet_2(STREET_2);

    address.setCity(CITY);
    address.setRegion(REGION);
    address.setCountry(COUNTRY);
    address.setIsDeliveryAddress(IS_DELIVERY_ADDRESS);

    addressDAO.persist(address);

    Long id = address.getId();

    address = addressDAO.findById(id);

    Assert.assertEquals(STREET_1, address.getStreet_1());
    Assert.assertEquals(STREET_2, address.getStreet_2());
    Assert.assertEquals(ZIP_CODE, address.getZipCode());
    Assert.assertEquals(CITY, address.getCity());
    Assert.assertEquals(REGION, address.getRegion());
    Assert.assertEquals(COUNTRY, address.getCountry());
    Assert.assertEquals(IS_DELIVERY_ADDRESS, address.getIsDeliveryAddress());

}

@Test
@Transactional
@Rollback(value = true)
public void testFindAll() {

    Address address1 = new Address();
    address1.setStreet_1(STREET_1);
    address1.setStreet_2(STREET_2);
    address1.setZipCode(ZIP_CODE);
    address1.setCity(CITY);
    address1.setRegion(REGION);

    address1.setIsDeliveryAddress(IS_DELIVERY_ADDRESS);

    Address address2 = new Address();
    address2.setStreet_1(STREET_1_UPDATE);
    address2.setStreet_2(STREET_2_UPDATE);

    addressDAO.persist(address1);
    addressDAO.persist(address2);

    List<Address> addressesList = addressDAO.findAll();

    Assert.assertNotNull(addressesList);
    Assert.assertTrue(addressesList.size() >= 2);
    Assert.assertTrue(addressesList.contains(address1));
    Assert.assertTrue(addressesList.contains(address2));
}
}

I have cleaned my project using Run as > Maven clean and Project > Clean..., and I updated the project Maven > Update project but nothing works. I am stuck now, if somebody can help me to solve this exception it would be great?

Thanks in advance.

Answer 1

Ok I solved that. When I ran run as > maven install it gave me the following error:

 maven error reading C:\Users\569128763\.m2\repository\org\springframework\spring-context\5.0.0.RC3\spring-context-5.0.0.RC3.jar invalid LOC header (bad signature)

So the jar file for spring-context was corrupted, I just deleted the springframework directory from my m2 repository and did Maven > Update project, then launched maven install once again and it worked.

Answer 2

Pay attention on root cause error. It's clear enough:

Caused by: java.lang.ClassNotFoundException: org.springframework.context.ApplicationContextException

Put Spring lib in your classpath.
