Sorry if I mess up with my question, I am just getting started configuring MVC, Spring, etc....
The issue that I am running into is that in my Spring MVC project all of my Autowired services are being successfully autowired when my application deploys (verified by setting breakpoints in Spring Tool Suite), but when I try to invoke a autowired service's method I run into a NullPointerException. I have looked all over at different configuration files and it seems like my servelt-context, root-context and web XML files should be ok (don't quote me on that and they are included below).
I am wondering if somehow I am not invoking the instance of the service created at deploy time? It seems strange that the Autowired setters can be called successfully but then the services end up being null. Any help you can provide is greatly appreciated!

InsuranceNoteDBServiceImpl:
(Here the setiNoteDAO is called with a instance of the iNoteDAO class, but when getNoteById is called iNoteDAO is null)

}
InsuranceNoteDBService:
public interface InsuranceNoteDBService {
void insertNote(BillerNote note);
BillerNote getNoteById(int noteId);
}
InsuranceNoteDAOImpl:
(Same thing happens here with the init() method that is setting the session factory)
#Service
public class InsuranceNoteDAOImpl implements InsuranceNoteDAO {
public SessionFactory sessionFactory;
#Autowired
public void init(SessionFactory factory) {
setSessionFactory(factory);
}
public void setSessionFactory(SessionFactory factory) {
this.sessionFactory = factory;

sessionFactory.getCurrentSession().save(note);
}
#Override
public BillerNote getNoteById(int noteId) {
return (BillerNote) sessionFactory.
getCurrentSession().
get(BillerNote.class, noteId);
}
}
InsuranceNoteDAO:
public interface InsuranceNoteDAO {
void insertNote(BillerNote note);
BillerNote getNoteById(int noteId);
}
Remove the init method and annotate the setter :
#Autowired
public void setSessionFactory(SessionFactory factory) {
this.sessionFactory = factory;
}

In your application you have two spring contexts: root application context (ContextLoaderListener) and web application context(DispatcherServlet). You need to understand the difference between them. Read here .
If you move your property resource definition to beans.xml(which is used for root context), your property value will be injected correctly throughout the application.
move this bean difinition to beans.xml
<context:property-placeholder location="classpath:properties/development.properties" order="1"/>.
I'm setting up a new SPring4 app using Thymeleaf and keep encountering the same issue when it comes to returning the view. I've searched don here and followed some online tutorials but the same error so I'm thinking it may be due to configuration, any help is appreciated, thanks.

Error appears only on calling of #OnMessage method.
All junit #Tests of repository class returns fine results.
What is wrong in my code?
Sorry for my english.
UPD:
It seems, that problem is in SessionFactory dependency because test method, that i add in #Repository:
public String testWS() {
return "Test is ok!";
}
returns fine result.
So, looks like i found the right way. I found it in Spring websocket documentation.
There are some steps what i did:
I put in type-level annotation:
#ServerEndpoint(value = "/WebsocketHome/actions", configurator = SpringConfigurator.class)
I added #Service and #Controller to my websocket classes and "context:component-scan" path to my app-context.xml file so that Spring can find corresponding beans.
I added the "spring-websocket" dependency in my pom.xml (i use maven)
Maybe it is not the right way, but it is works fine for me.
#Today jan 31' 2022 Just Add "spring-websocket" dependency
I have a spring application which implemented spring security.I was trying to overide method UserDetails retrieveUser(String username,
UsernamePasswordAuthenticationToken pWord){} by extending my LoginController with AbstractUserDetailsAuthenticationProvider
In this Class I used #Autowired annotation like
#Autowired
private UserManager userManager;
Unfortunately userManager is null inside retrieveUser method
Following is My code:
LoginController.java
package com.springmaster.controller;
...
....
#Controller
public class LoginController extends AbstractUserDetailsAuthenticationProvider {
#Autowired
private UserManager userManager;
/**
* #return the userManager
*/
public UserManager getUserManager() {
return userManager;
}
/**
* #param userManager the userManager to set
*/
public void setUserManager(UserManager userManager) {
this.userManager = userManager;
}
#RequestMapping(value = "/login", method = RequestMethod.GET)
public ModelAndView login(
#RequestParam(value = "error", required = false) String error,
#RequestParam(value = "logout", required = false) String logout) {
System.out.println("----------"+this.userManager); //getting not null here
ModelAndView model = new ModelAndView();
if (error != null) {
model.addObject("error", "Invalid username and password!");
}
if (logout != null) {
model.addObject("msg", "You've been logged out successfully.");
}
model.setViewName("login");
return model;
}
#Override
protected void additionalAuthenticationChecks(UserDetails arg0,
UsernamePasswordAuthenticationToken arg1)
throws AuthenticationException {
// TODO Auto-generated method stub
}
#Override
protected UserDetails retrieveUser(String username,
UsernamePasswordAuthenticationToken pWord)
throws AuthenticationException {
String password = (String) pWord.getCredentials();
UserManager userManager = new UserManagerImpl();
System.out.println("----------"+this.userManager); //getting null here
List <UserEntity> userEntities= userManager.getAllUsers(username);
List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
authorities.add(new GrantedAuthorityImpl("ROLE_Admin"));
return new User(username, password, true, // enabled
true, // account not expired
true, // credentials not expired
true, // account not locked
authorities);
}

Some research gave a brief idea about it like
web.xml is creating two Spring application contexts. Let's call them Security (after security-context.xml) and Servlet (after servlet-context.xml). Security is created by the ContextLoaderListener listener, and Servlet is created by the DispatcherServlet servlet. Security is the parent of Servlet. That means that the beans in Security are only visible to other beans in Security, and the beans in Servlet can see both the beans in Security and in Servlet.
As a beginner can any one tell me what all configuration I should do in configuration files to overcome this barrier
Any Help will be highly appreciated
Thanks in advance
I realize this question has been asked many times, but those answers don't seem to get me working.
The class which has the #Autowired field:
#Component
public class SpecialClaimsCaseManager {
#Autowired
private SpecialClaimsCaseRepositoryService<SpecialClaimsCaseDto> service;
public SpecialClaimsCaseManager() {
}
public Collection<SpecialClaimsCase> findAll() {
return convertToSpecialClaimsCase(service.findAll());
}
The interface SpecialClaimsCaseRepositoryService
public interface SpecialClaimsCaseRepositoryService<C extends SpecialClaimsCaseDto> {
//Some method signatures, not relevant
The implementation class (what should be injected)
#Service("specialClaimsCaseRepositoryService")
public class SpecialClaimsCaseRepositoryServiceImpl implements SpecialClaimsCaseRepositoryService<SpecialClaimsCaseDto> {
//Some method implementations, not relevant

Full stack trace (fpasted because it's pretty long) http://fpaste.org/116696/14049194/
So, as we can see, mvc:annotation-driven is enabled, and autowiring is enabled. If I understand this correctly (I might not, pretty new to Spring), this should be all I need. SpecialClaimsCaseRepositoryService is an interface, if that matters, though I don't think it should as this same #Autowiring worked fine in another class annotated with #Controller.
Thanks for any help!
You'll notice from your stack trace that the exception occurs in the process of initializing the root application context loaded by the ContextLoaderListener. That's taken from
<!-- Spring Configuration Files -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
WEB-INF/application-security.xml
classpath*:sch_model_spring.xml
</param-value>
</context-param>
In those two, you are scanning
<context:component-scan base-package="com.redacted.sch.model"/>
but not the com.redacted.sch.service... package that is required by one of the beans.
Caused by: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.redacted.sch.service.SpecialClaimsCaseRepositoryService com.redacted.sch.model.SpecialClaimsCaseManager.specialClaimsCaseRepositoryService;
In this case, xyz.model.SpecialClaimsCaseManager has an #Autowired field of type xyz.service.SpecialClaimsCaseRepositoryService, but no such bean exists.
Don't mix component-scanned folders between application contexts, those loaded by ContextLoaderListener vs DispatcherServlet. Refactor so that application beans are loaded by the ContextLoaderListener and controller-related beans are loaded by the DispatcherServlet.
