how can i fix "Error 401 Unauthorized" on Spring Boot

how can i fix "Error 401 Unauthorized" on Spring Boot - java

I started watching a Tutorial on how to make a very basic Spring Boot Project. https://www.youtube.com/watch?v=vtPkZShrvXQ
No matter what i do i always get error 401, even when i copy the code 1-1.
Thank you in advance for taking your time to help me.
I tried putting this into the application.properties
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://localhost:3306/LoginDB
spring.datasource.username=root
spring.datasource.password=
I made following Files

If you don't need spring security in your project then remove below 2 dependencies from your pom.xml file
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-oauth2-resource-server</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
And if you need basic security then only use 2nd dependency And default user name is "user" and password you will get from console log.

Mockito testing void method which throws exception. Spring Boot, eclipse IDE

How to test a void method which throws an exception?
I've read many publications here and on others pages including Mockico docs form https://javadoc.io/static/org.mockito/mockito-core/3.12.4/org/mockito/Mockito.html#5. And my test still won't pass. I don't know what I'm doing wrong I always get red.
Maybe it is related to a wrongly implemented exception class.
Here is my code:
Repo:
import org.springframework.data.jpa.repository.JpaRepository;
import succeed.app.start.model.User;
public interface UserRepository extends JpaRepository<User, Long> {
}
Service interface:
public interface UserService {
void deleteUserById(long userId);
}
Service implementation:
#Service
public class UserServiceImpl implements UserService {
private UserRepository userRepository;
public UserServiceImpl(UserRepository userRepository) {
this.userRepository = userRepository;
}
#Override
public void deleteUserById(long userId) {
userRepository.findById(userId).orElseThrow(() -> new ResourceNotFoundException("User", "ID", userId));
userRepository.deleteById(userId);
}
}
Exception class:
import org.springframework.http.HttpStatus;
import org.springframework.web.bind.annotation.ResponseStatus;
#ResponseStatus(value = HttpStatus.NOT_FOUND)
public class ResourceNotFoundException extends RuntimeException {
private final static long serialVersionUID = 1L;
private String resourceName;
private String fieldName;
private Object fieldValue;
public ResourceNotFoundException(String resourceName, String fieldName, Object fieldValue) {
super(String.format("%s not found with %s : %s", resourceName, fieldName, fieldValue));
this.resourceName = resourceName;
this.fieldName = fieldName;
this.fieldValue = fieldValue;
}
public String getResourceName() {
return resourceName;
}
public String getFieldName() {
return fieldName;
}
public Object getFieldValue() {
return fieldValue;
}
}
Test class:
import org.junit.jupiter.api.DisplayName;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.mockito.Mock;
import org.mockito.junit.jupiter.MockitoExtension;
import static org.mockito.Mockito.doThrow;
import succeed.app.start.exception.ResourceNotFoundException;
import succeed.app.start.repository.UserRepository;
#ExtendWith(MockitoExtension.class)
public class UserServiceImplTest {
#Mock

#Mock
UserServiceImpl userService;
#Test
#DisplayName("Should throw ResourceNotFoundException when user doesn't exist.")
void shouldThrowsResourceNotFoundException() {
final long nonExistingId = 12902450235L;
doThrow(new ResourceNotFoundException("User", "ID", nonExistingId)).when(userService).deleteUserById(nonExistingId);
userService.deleteUserById(nonExistingId);
}
}

There are a couple of things wrong here.
First, other than the message in the #Display annotation, your test doesn't really expect the exception to be thrown. You need to explicitly code this behavior, e.g. by using assertThrows.
Second, you're mocking the UserService, so the test won't really do anything - in the same method, you've defined some fake behavior and then tested it. Instead, you should mock the UserRepository and then make test that the UserService calls it correctly:
#ExtendWith(MockitoExtension.class)
public class UserServiceImplTest {
#Mock
UserRepository userRepository;
#InjectMocks
UserServiceImpl userService;
#Test
#DisplayName("Should throw ResourceNotFoundException when user doesn't exist.")
void shouldThrowsResourceNotFoundException() {
final long nonExistingId = 12902450235L;
doReturn(Optional.empty()).when(userRepository).findById(nonExistingId);
assertThrows(
ResourceNotFoundException.class,
() -> userService.deleteUserById(nonExistingId));
}
}

#RestController("/todo")// you can give any URL here
public class TodoController {
#Autowired
private TodoRepo todoRepo;

return todoRepo.findAll();
}
#PostMapping("/save")// you can give any URL here
public TodoModel save(#Valid #NotNull #RequestBody TodoModel todoItem) {
todoRepo.save(todoItem);
return todoItem;
}
}
you give the mapping to the method like this. you can give any URL name. This is the main reason you get a 404 error.

There is issue in your mapping. You didn't specify the mapping path so findAll and save has default mapping as empty then controller could not understand which API you calling. Add below things and try.
#GetMapping(value="/findAll")
#PostMapping(value=/save")

The TodoApplication class must be above this one level.
change this:
from
package com.assignment.todo.Todo;
to
package com.assignment.todo;

Unit testing for spring boot RESTFUL Controller

I am trying to do unit testing for spring boot RESTFUL controller but I am receiving a null pointer exception. The application has a StudentController which depends on a StudentService.
Here is the controller code:
package com.demo.student.demo.controller;
import com.demo.student.demo.annotation.ApiDescription;
import com.demo.student.demo.entity.Student;
import com.demo.student.demo.entity.StudentDto;
import com.demo.student.demo.service.StudentService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.modelmapper.ModelMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;
import java.util.List;
import java.util.stream.Collectors;
#RestController
#RequestMapping(value = "/v1/students")
#Api(description = "This is a general description for StudentController RESTFUL Controller")
public class StudentController {
private StudentService studentService;
private ModelMapper modelMapper;
public StudentController(ModelMapper modelMapper, StudentService studentService){
this.studentService = studentService;
this.modelMapper = modelMapper;
}
private StudentDto convertToDto(Student student) {
StudentDto studentDto = modelMapper.map(student, StudentDto.class);
return studentDto;
}
private Student convertToEntity(StudentDto studentDto) {
Student student = modelMapper.map(studentDto, Student.class);
return student;
}
#GetMapping
#ApiOperation("Returns a list of all students in the system.")
#ApiDescription("FIND_ALL_STUDENTS.md")
public List<StudentDto> findAll(){
List<Student> students = studentService.findAl();
return students.stream()
.map(student -> convertToDto(student))
.collect(Collectors.toList());
}
#GetMapping("/{id}")
#ApiOperation("Returns a specific Student by his/her identifier. 404 if does not exist.")
#ApiDescription("FIND_STUDENT_BY_ID.md")
public StudentDto findById(#PathVariable("id") long id){
return convertToDto(studentService.findById(id));
}
#PostMapping
#ApiOperation("Creates/Updates a new Student.")
#ApiDescription("SAVE_OR_UPDATE_STUDENT.md")
public StudentDto saveOrUpdate(#RequestBody StudentDto studentDto) {
Student student = convertToEntity(studentDto);
student.setUsername(student.getEmail() + "----" + student.getId());
Student studentCreated = studentService.saveOrUpdate(student);
return convertToDto(studentCreated);
}
#DeleteMapping("/{id}")
#ApiOperation("Deletes a Student from the system. 404 if the Student's identifier is not found.")
#ApiDescription("DELETE_STUDENT_BY_ID.md")
public void deleteById(#PathVariable("id") long id){
studentService.deleteById(id);
}
}
And here is the service implementation code:
package com.demo.student.demo.service;
import com.demo.student.demo.entity.Student;
import com.demo.student.demo.exception.StudentNotFoundException;
import com.demo.student.demo.repository.StudentRepository;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.util.List;
#Service
public class StudentServiceImpl implements StudentService {
private StudentRepository studentRepository;
#Autowired
public StudentServiceImpl(StudentRepository studentRepository){
this.studentRepository = studentRepository;
}
#Override
public List<Student> findAl() {
return studentRepository.findAll();
}
#Override
public Student findById(long id) {
return studentRepository.findById(id).orElseThrow(() -> new StudentNotFoundException(id));
}
#Override
public Student saveOrUpdate(Student student) {
studentRepository.save(student);
return student;
}
#Override
public void deleteById(long id) {
if(this.findById(id) != null)
studentRepository.deleteById(id);
}
}
And this is the test class for the controller:
package com.demo.student.demo.controller;
import com.demo.student.demo.entity.Student;
import com.demo.student.demo.service.StudentService;
import com.demo.student.demo.service.StudentServiceImpl;

#Test
void findAll() throws Exception {

List<Student> students = Arrays.asList(student);
given(studentService.findAl()).willReturn(students);
// when + then
mockMvc.perform(get(URI))
.andExpect(status().isOk())
.andExpect(content().json("[{'id':1,'email':'test#test.test'}]"));
}
}

When I run the test I receive a NULL POINTER EXCEPTION pointing to a code line in the StudentController class where the student service retrieves all the student data: List<Student> students = studentService.findAl();
java.lang.NullPointerException: null
at com.demo.student.demo.controller.StudentController.findAll
Can anyone tell me what is the problem?

Finally I found an answer, to add #ExtendWith(SpringExtension.class) in order to work in JUnit5.
So, my controller test class would be:
package com.demo.student.demo.controller;
import com.demo.student.demo.entity.Student;
import com.demo.student.demo.service.StudentService;
import org.junit.jupiter.api.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.test.context.junit.jupiter.SpringExtension;
import org.springframework.test.web.servlet.MockMvc;
import java.util.Arrays;
import java.util.List;
import static org.mockito.BDDMockito.given;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.*;
#ExtendWith(SpringExtension.class)
#WebMvcTest
class StudentControllerTest {
private final static String URI = "/v1/students";
#Autowired
private MockMvc mockMvc;
#MockBean
private StudentService studentService;
#Test
void findAll() throws Exception {
// given
Student student = new Student(1, "test", "test#test.test");
List<Student> students = Arrays.asList(student);
given(studentService.findAl()).willReturn(students);
// when + then
mockMvc.perform(get(URI))
.andExpect(status().isOk())
.andExpect(content().json("[{'id':1,'email':'test#test.test'}]"));
}
}

There are a couple of things with your test, first you are mixing JUnit4 and JUnit5, don't, second you are trying to work against the Spring Boot created mock, don't. Finally you are creating a new mock for the service and register behavior.
Remove the #RunWith annotation, that is for JUnit4 tests and not needed with JUnit5.
Remove your #BeforeEach method, as that interferes with the prepared MockMvc by Spring Boot (through the #WebMvcTest) and the mock created by #MockBean.
Remove StudentService studentService = mock(StudentService.class); from your test method. #MockBean already creates a mock. This creates a new mock, not tied to the controller.
The version of Spring Boot used (2.0.x) doesn't yet have an #WebMvcTest that includes the #ExtendWith annotation (as of Spring Boot 2.1.x). So add that as well to use the proper execution model.
pro-tip: Remove the no-args constructor and #Autowired from your StudentController, Spring is smart enough to pick the single constructor.

Annotate your test class this way.
#RunWith(SpringRunner.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
Autowire this:
#Autowired
private WebApplicationContext wac;
This is just a class variable:
private MockMvc mockMvc;
Your setup method:
#Before
public void setup() {
this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
}
Before this line:
given(studentService.findAl()).willReturn(students);
Create:
StudentService studentService = org.mockito.Mockito.mock(StudentService.class);
It should run.
