Spring REST + Spring Security Example

logo

In this article, we will enhance the previous Spring REST Validation Example, by adding Spring Security to perform authentication and authorization for the requested URLs (REST API endpoints)

Technologies used :

  • Spring Boot 2.1.2.RELEASE
  • Spring 5.1.4.RELEASE
  • Spring Security 5.1.3.RELEASE
  • Spring Data JPA 2.1.4.RELEASE
  • H2 In-memory Database 1.4.197
  • Tomcat Embed 9.0.14
  • JUnit 4.12
  • Maven 3
  • Java 8

3. Spring Controller

Review the Book Controller again, later we will integrate with Spring Security to secure the REST endpoints.

BookController.java

package com.mkyong;

import com.mkyong.error.BookNotFoundException;
import com.mkyong.error.BookUnSupportedFieldPatchException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;
import org.springframework.util.StringUtils;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.*;

import javax.validation.Valid;
import javax.validation.constraints.Min;
import java.util.List;
import java.util.Map;

@RestController
@Validated
public class BookController {

    @Autowired
    private BookRepository repository;

    // Find
    @GetMapping("/books")
    List<Book> findAll() {
        return repository.findAll();
    }

    // Save
    @PostMapping("/books")
	@ResponseStatus(HttpStatus.CREATED)
    Book newBook(@Valid @RequestBody Book newBook) {
        return repository.save(newBook);
    }

    // Find
    @GetMapping("/books/{id}")
    Book findOne(@PathVariable @Min(1) Long id) {
        return repository.findById(id)
                .orElseThrow(() -> new BookNotFoundException(id));
    }

    // Save or update
    @PutMapping("/books/{id}")
    Book saveOrUpdate(@RequestBody Book newBook, @PathVariable Long id) {

        return repository.findById(id)
                .map(x -> {
                    x.setName(newBook.getName());
                    x.setAuthor(newBook.getAuthor());
                    x.setPrice(newBook.getPrice());
                    return repository.save(x);
                })
                .orElseGet(() -> {
                    newBook.setId(id);
                    return repository.save(newBook);
                });
    }

    // update author only
    @PatchMapping("/books/{id}")
    Book patch(@RequestBody Map<String, String> update, @PathVariable Long id) {

        return repository.findById(id)
                .map(x -> {

                    String author = update.get("author");
                    if (!StringUtils.isEmpty(author)) {
                        x.setAuthor(author);

                        // better create a custom method to update a value = :newValue where id = :id
                        return repository.save(x);
                    } else {
                        throw new BookUnSupportedFieldPatchException(update.keySet());
                    }

                })
                .orElseGet(() -> {
                    throw new BookNotFoundException(id);
                });

    }

    @DeleteMapping("/books/{id}")
    void deleteBook(@PathVariable Long id) {
        repository.deleteById(id);
    }

}

P.S Other components or repositories are not listed here, please refer to the previous Spring REST Validation Example

4. Spring Security

4.1 Create a new @Configuration class and extends WebSecurityConfigurerAdapter. In below example, we will use the HTTP Basic authentication to protect the REST endpoints. Read comment for self explanatory.

SpringSecurityConfig.java

package com.mkyong.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpMethod;
import org.springframework.security.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@Configuration
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {

    // Create 2 users for demo
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {

        auth.inMemoryAuthentication()
                .withUser("user").password("{noop}password").roles("USER")
                .and()
                .withUser("admin").password("{noop}password").roles("USER", "ADMIN");

    }

    // Secure the endpoins with HTTP Basic authentication
    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http
                //HTTP Basic authentication
                .httpBasic()
                .and()
                .authorizeRequests()
                .antMatchers(HttpMethod.GET, "/books/**").hasRole("USER")
                .antMatchers(HttpMethod.POST, "/books").hasRole("ADMIN")
                .antMatchers(HttpMethod.PUT, "/books/**").hasRole("ADMIN")
                .antMatchers(HttpMethod.PATCH, "/books/**").hasRole("ADMIN")
                .antMatchers(HttpMethod.DELETE, "/books/**").hasRole("ADMIN")
                .and()
                .csrf().disable()
                .formLogin().disable();
    }

    /*@Bean
    public UserDetailsService userDetailsService() {
        //ok for demo
        User.UserBuilder users = User.withDefaultPasswordEncoder();

        InMemoryUserDetailsManager manager = new InMemoryUserDetailsManager();
        manager.createUser(users.username("user").password("password").roles("USER").build());
        manager.createUser(users.username("admin").password("password").roles("USER", "ADMIN").build());
        return manager;
    }*/

}

4.2 Done, the above Spring REST API endpoints is protected by Spring Security :)

5. Spring Boot

Normal Spring Boot application to start the REST endpoints and insert 3 books into the H2 database for demo.

StartBookApplication

package com.mkyong;

import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

import java.math.BigDecimal;

@SpringBootApplication
public class StartBookApplication {

    // start everything
    public static void main(String[] args) {
        SpringApplication.run(StartBookApplication.class, args);
    }

    @Bean
    CommandLineRunner initDatabase(BookRepository repository) {
        return args -> {
            repository.save(new Book("A Guide to the Bodhisattva Way of Life", "Santideva", new BigDecimal("15.41")));
            repository.save(new Book("The Life-Changing Magic of Tidying Up", "Marie Kondo", new BigDecimal("9.69")));
            repository.save(new Book("Refactoring: Improving the Design of Existing Code", "Martin Fowler", new BigDecimal("47.99")));
        };
    }
}

6. Demo

6.1 Start the Spring Boot application.


mvn spring-boot:run

6.2 A normal GET and POST will return a 401, all endpoints are protected, need authentication.


> curl localhost:8080/books

{	
	"timestamp":"2019-02-25T04:05:14.709+0000",
	"status":401,
	"error":"Unauthorized",
	"message":"Unauthorized",
	"path":"/books"
}

> curl -X POST localhost:8080/books -H "Content-type:application/json" 
	-d {\"name\":\"ABC\",\"author\":\"mkyong\",\"price\":\"8.88\"}
	
{
	"timestamp":"2019-02-25T04:11:17.150+0000",
	"status":401,
	"error":"Unauthorized",
	"message":"Unauthorized",
	"path":"/books"
}

6.3 Send a GET request along with user login.


> curl localhost:8080/books -u user:password
[
	{"id":1,"name":"A Guide to the Bodhisattva Way of Life","author":"Santideva","price":15.41},
	{"id":2,"name":"The Life-Changing Magic of Tidying Up","author":"Marie Kondo","price":9.69},
	{"id":3,"name":"Refactoring: Improving the Design of Existing Code","author":"Martin Fowler","price":47.99}
]

> curl localhost:8080/books/1 -u admin:password

{
	"id":1,
	"name":"A Guide to the Bodhisattva Way of Life",
	"author":"Santideva",
	"price":15.41
}

6.4 Try to send a POST request with ‘user’ login, it will return 403, Forbidden error. This is because the user has no right to send a POST request.


> curl -X POST localhost:8080/books -H "Content-type:application/json" 
	-d {\"name\":\"ABC\",\"author\":\"mkyong\",\"price\":\"8.88\"} -u user:password

{
	"timestamp":"2019-02-25T04:16:58.702+0000",
	"status":403,
	"error":"Forbidden",
	"message":"Forbidden",
	"path":"/books"
}

Review the Spring Security configuration again. To send POST,PUT,PATCH or DELETE request, we need admin

SpringSecurityConfig.java

    @Override
    protected void configure(HttpSecurity http) throws Exception {

        http
                //HTTP Basic authentication
                .httpBasic()
                .and()
                .authorizeRequests()
                .antMatchers(HttpMethod.GET, "/books/**").hasRole("USER")
                .antMatchers(HttpMethod.POST, "/books").hasRole("ADMIN")
                .antMatchers(HttpMethod.PUT, "/books/**").hasRole("ADMIN")
                .antMatchers(HttpMethod.PATCH, "/books/**").hasRole("ADMIN")
                .antMatchers(HttpMethod.DELETE, "/books/**").hasRole("ADMIN")
                .and()
                .csrf().disable()
                .formLogin().disable();
    }

}

6.5 Try to send a POST request with admin login


> curl -X POST localhost:8080/books -H "Content-type:application/json" 
	-d {\"name\":\"ABC\",\"author\":\"mkyong\",\"price\":\"8.88\"} -u admin:password
	
{
	"id":4,
	"name":"ABC",
	"author":"mkyong",
	"price":8.88
}


> curl localhost:8080/books -u user:password

[
	{"id":1,"name":"A Guide to the Bodhisattva Way of Life","author":"Santideva","price":15.41},
	{"id":2,"name":"The Life-Changing Magic of Tidying Up","author":"Marie Kondo","price":9.69},

7. Spring Security Integration Test

7.1 Test with @WithMockUser and MockMvc

BookControllerTest.java

package com.mkyong;


import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.security.test.context.support.WithMockUser;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;

import java.math.BigDecimal;
import java.util.Optional;

import static org.hamcrest.Matchers.is;
import static org.mockito.Mockito.when;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.jsonPath;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
@ActiveProfiles("test")
public class BookControllerTest {

    @Autowired
    private MockMvc mockMvc;

    @MockBean
    private BookRepository mockRepository;

    @Before
    public void init() {
        Book book = new Book(1L, "A Guide to the Bodhisattva Way of Life", "Santideva", new BigDecimal("15.41"));
        when(mockRepository.findById(1L)).thenReturn(Optional.of(book));
    }

    //@WithMockUser(username = "USER")
    @WithMockUser("USER")
    @Test
    public void find_login_ok() throws Exception {

        mockMvc.perform(get("/books/1"))
                .andDo(print())
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.id", is(1)))
                .andExpect(jsonPath("$.name", is("A Guide to the Bodhisattva Way of Life")))
                .andExpect(jsonPath("$.author", is("Santideva")))
                .andExpect(jsonPath("$.price", is(15.41)));
    }

    @Test
    public void find_nologin_401() throws Exception {
        mockMvc.perform(get("/books/1"))
                .andDo(print())
                .andExpect(status().isUnauthorized());
    }

}

7.2 Test with TestRestTemplate

BookControllerRestTemplateTest.java

package com.mkyong;

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.skyscreamer.jsonassert.JSONAssert;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.boot.test.mock.mockito.MockBean;
import org.springframework.boot.test.web.client.TestRestTemplate;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.junit4.SpringRunner;

import java.math.BigDecimal;
import java.util.Optional;

import static org.junit.Assert.assertEquals;
import static org.mockito.Mockito.when;

@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
@ActiveProfiles("test")
public class BookControllerRestTemplateTest {

    private static final ObjectMapper om = new ObjectMapper();

    //@WithMockUser is not working with TestRestTemplate
    @Autowired
    private TestRestTemplate restTemplate;

    @MockBean
    private BookRepository mockRepository;

    @Before
    public void init() {
        Book book = new Book(1L, "A Guide to the Bodhisattva Way of Life", "Santideva", new BigDecimal("15.41"));
        when(mockRepository.findById(1L)).thenReturn(Optional.of(book));
    }

    @Test
    public void find_login_ok() throws Exception {

        String expected = "{id:1,name:\"A Guide to the Bodhisattva Way of Life\",author:\"Santideva\",price:15.41}";

        ResponseEntity<String> response = restTemplate
                .withBasicAuth("user", "password")
                .getForEntity("/books/1", String.class);

        printJSON(response);

        assertEquals(MediaType.APPLICATION_JSON_UTF8, response.getHeaders().getContentType());
        assertEquals(HttpStatus.OK, response.getStatusCode());

        JSONAssert.assertEquals(expected, response.getBody(), false);

    }

    @Test
    public void find_nologin_401() throws Exception {

        String expected = "{\"status\":401,\"error\":\"Unauthorized\",\"message\":\"Unauthorized\",\"path\":\"/books/1\"}";

        ResponseEntity<String> response = restTemplate
                .getForEntity("/books/1", String.class);

        printJSON(response);

        assertEquals(MediaType.APPLICATION_JSON_UTF8, response.getHeaders().getContentType());
        assertEquals(HttpStatus.UNAUTHORIZED, response.getStatusCode());

        JSONAssert.assertEquals(expected, response.getBody(), false);

    }

    private static void printJSON(Object object) {
        String result;
        try {
            result = om.writerWithDefaultPrettyPrinter().writeValueAsString(object);
            System.out.println(result);
        } catch (JsonProcessingException e) {
            e.printStackTrace();
        }
    }

}

P.S The @WithMockUser is not working with TestRestTemplate, we need authenticate user with `.withBasicAuth`

Is it not unsecured and big security risk to pass user name and password in the request url as shown in the example above ?

Hi, could you explain your code, i can’t login
auth.inMemoryAuthentication()
.withUser(“user”).password(“{noop}password”).roles(“USER”)
.and()
.withUser(“admin”).password(“{noop}password”).roles(“USER”, “ADMIN”);

Tests:
curl localhost:8080/books
{“timestamp”:”2019-06-17T20:59:01.717+0000″,”status”:401,”error”:”Unauthorized”,”message”:”Unauthorized”,”path”:”/books”} this is ok

When i try
curl localhost:8080/books -u user:password nothing happens…
When i try the url “localhost:8080/login” on the browser i get the login page but whatever i try i get “Bad credentials”

What is my “user” and my “password”?

Thank you

Guido
