following the answer given in this question, I have removed the spring-webmvc.jar file from my lib to avoid a repetition with the one in the core project. However, when I do this, it seems that the @Autowired for at least a bean does not work any more.
The class having the @Autowired is the following (in which none of the field is filled):
public class SecurityUserCheckBeforeControllerHandler implements BeforeControllerHandler
{
@Resource(name = "userService")
private UserService userService;
@Autowired
private CMSPageContextService cmsPageContextService;
@Override
public boolean beforeController(final HttpServletRequest request, final HttpServletResponse response,
final HandlerMethod handler) throws IOException
{
// Code where the autowired fields are used (-> produces null pointer)
}
}
The spring configuration can be summarized as follows:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- other beans in the list -->
</util:list>

</beans>
If I follow the advise given in most of the similar questions (i.e. adding an @Component above the class that would be scanned), the bean will be created twice:
- with the list given in the config file:
The autowired fields will be null which will still give a
NullPointerExceptionwhen the bean in the list is used - by the
component-scan: The fields are correctly autowired but the bean is not used in the list.
Strangely, if I put back the spring-webmvc.jar previously removed because of this question, the @Autowired will work as expected.
Trying to compare the stacktraces between the two configurations, I saw that the beans are created at different moments in the class org.springframework.context.support.AbstractApplicationContext during the startup of the server.
Last point: there is no error during the compilation and the startup of the server.
Do you have any idea for a solution please?
Thank you for reading me,
Laurent
