java.lang.IllegalStateException: Failed to load ApplicationContext error in Spring Boot - postgresql

Question

I am new to unit testing and I have to test my methods in spring boot.
I created application with Spring Security JWT Authentication + PostgreSQL – RestAPIs SpringBoot + Spring MVC + Spring JPA from this link
then I created controller for users to edit update ect.
My users controller looks like this
#RestController
#RequestMapping("/users")
public class Users {
#Autowired
private UserService userService;
#GetMapping(value = "/*")//can access with this root
#PreAuthorize("hasRole('ADMIN')") //Only admin can view all users' details
public List<User> AllUsers(){
return this.userService.getAllUsers();
}
#GetMapping(value = "/{username}")//can access with this root
public User GetOneUser(#PathVariable(value = "username") String username){
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
String auth_name = auth.getName(); //get logged in username
if(auth_name.equals(username)||this.userService.isAdmin(auth_name)){//admin and user can see the details
return this.userService.getUser(username);
}
else{
return null;
}
}
#DeleteMapping(value = "/{id}")//can access with this root
#PreAuthorize("hasRole('ADMIN')") //Only admin can delete user
public void DeleteUser(#PathVariable(value = "id") Long id){
this.userService.deleteUser(id);
}
#PostMapping(value = "/{username}")//can access with this root
public User EditUser(#PathVariable(value = "username") String username,#RequestBody SignUpForm user) {//only user can edit
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
String auth_name = auth.getName(); //get logged in username
User upUser=null;
if(auth_name.equals(username)){
upUser=this.userService.updateUser(username,user);
}
return upUser;
}
}
then I created UserService like this:
#Service
public class UserService {
#Autowired
private UserRepository userRepository;
#Autowired
private RoleRepository roleRepository;
#Autowired
PasswordEncoder encoder;
public List<User> getAllUsers(){
// return topics;
List<User> users=new ArrayList<>();
userRepository.findAll().forEach(users::add);
return users;
}
public boolean isAdmin(String username){
boolean flag=false;
if(this.userRepository.existsByUsername(username)){
User user=this.userRepository.findByUsername(username).get();
Role adminRole = roleRepository.findByName(RoleName.ROLE_ADMIN)
.orElseThrow(() -> new RuntimeException("Fail! -> Cause: User Role not find."));
if(user.getId().equals(adminRole.getId())){
flag=true;
}
}
return flag;
}
public User getUser(String username){
return userRepository.findByUsername(username).orElse(null);
}
public User updateUser(String username, SignUpForm user) {
if(userRepository.existsByUsername(username)) {
User ExistingUser=userRepository.findByUsername(username).get();
if(ExistingUser.getName()!=user.getName()){
ExistingUser.setName(user.getName());
}
if(ExistingUser.getUsername()!=user.getUsername()){
ExistingUser.setUsername(user.getUsername());
}
if(ExistingUser.getPassword()!=user.getPassword()){
ExistingUser.setPassword(encoder.encode(user.getPassword()));
}
if(ExistingUser.getEmail()!=user.getEmail()){
ExistingUser.setEmail(user.getEmail());
}
Set<String> Roles =user.getRole();
Set<Role> roles = new HashSet<>();
Roles.forEach(role -> {
switch(role) {
case "admin":
Role adminRole = roleRepository.findByName(RoleName.ROLE_ADMIN)
.orElseThrow(() -> new RuntimeException("Fail! -> Cause: User Role not find."));
roles.add(adminRole);
break;
case "pm":
Role pmRole = roleRepository.findByName(RoleName.ROLE_PM)
.orElseThrow(() -> new RuntimeException("Fail! -> Cause: User Role not find."));
roles.add(pmRole);
break;
default:
Role userRole = roleRepository.findByName(RoleName.ROLE_USER)
.orElseThrow(() -> new RuntimeException("Fail! -> Cause: User Role not find."));
roles.add(userRole);
}
});
if(ExistingUser.getRoles()!=roles){
ExistingUser.setRoles(roles);
}
userRepository.save(ExistingUser);
}
return userRepository.findByUsername(user.getUsername()).get();
}
public void deleteUser(Long id) {
userRepository.deleteById(id);
}
}
it works.
But then I created class for testing that tests getUser() method from UserService
#WebMvcTest
#RunWith(SpringRunner.class)
public class UserServiceTest {
#MockBean
UserRepository repository;
#Autowired
UserService userService;
#Test
public void getUserTest(){
User user=this.userService.getUser("arife");
assertThat(user).isNotNull();
}
}
But it gives me error that looks like this:

Please can someone help me?

Answer 1

Is pretty hard to follow up your problem if you don't add more details (log trace, code snapshots...)
But maybe you can find this pet project done by me (https://github.com/geeksusma/jwt-rest-controller)
Basically is a RestController which works with JWT.
I hope it could help

Answer 2

Now I wrote like this
#DataJpaTest
#RunWith(SpringRunner.class)
public class UserServiceTest {
#MockBean
UserService userService;
#Test
public void getUserTest(){
assertThat(this.userService.getUser("arife")).isNotNull();
}
}
and then I added new File application-test.properties
#ActiveProfiles("test")
#PostgreSQL
spring.datasource.url=jdbc:postgresql:
spring.datasource.username=
spring.datasource.password=
spring.jpa.generate-ddl=true
now it gives me error
java.lang.AssertionError:
