問題描述

我正在用 spring boot 編寫一個 RESTful api.我正在使用 spring boot、jersey、mongo db、swagger、spring boot security 和 jwt.

I'm writing a RESTful api with spring boot. I'm using spring boot, jersey, mongo db, swagger, spring boot security and jwt.

我已經編寫了模型、數據庫請求的存儲庫.現在我已經集成了 Security 和 jwt 令牌.

I have written the models, the repositories for the requests to the DB. Now I have integrated the Security and jwt token.

現在我需要離散化用戶的角色，因為用戶無法調用需要管理員權限的路由.

Now I need to discretize the role of the users, because a user cant call a route that need an admin priviledges.

我有一個登錄路徑，它返回一個令牌.這是我的 SecurityConfig 的代碼

I have a route for login, it's return a token. This is the code of my SecurityConfig

...
@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter{

    @Autowired
    UserRepository userRepository;

    @Override
    public void configure(HttpSecurity httpSecurity) throws Exception {
        httpSecurity.csrf().disable().authorizeRequests()
                .antMatchers("/").permitAll()
                .antMatchers("/api/swagger.json").permitAll()
                .antMatchers(HttpMethod.POST, "/login").permitAll()
                .antMatchers("/api/*").authenticated()
                .and()

                .addFilterBefore(new JWTLoginFilter("/login", authenticationManager(), userRepository),
                        UsernamePasswordAuthenticationFilter.class)

                .addFilterBefore(new JWTAuthenticationFilter(),
                        UsernamePasswordAuthenticationFilter.class);
    }

}

我編寫了 JWTLoginFilter，當用戶登錄時返回我的令牌

I written the JWTLoginFilter that return me the token when user makes login

...
@Override
public Authentication attemptAuthentication(HttpServletRequest req, HttpServletResponse res) throws AuthenticationException, IOException, ServletException {
    Credential creds = new ObjectMapper().readValue(req.getInputStream(), Credential.class);

    User user = userRepository.login(creds);

    if (user == null)
        throw new BadCredentialsException("");

    UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(
        creds.getUsername(),
        creds.getPassword()
    );

    return token;
}
...

我想在方法的端點類中插入它

I want insert this on my endpoint class on method

@PreAuthorize("hasRole('ROLE_ADMIN')")

這是端點的一部分

....

@Component
@Path("story")
@Api(value = "Story", produces = "application/json")
public class StoryEndpoint {

    private static final Logger LOGGER = LoggerFactory.getLogger(StoryEndpoint.class);

    @Autowired
    StoryRepository storyRepository;


    @GET
    @Path("/")
    @Produces(MediaType.APPLICATION_JSON)
    @PreAuthorize("hasRole('ROLE_ADMIN')") <--- I want insert here
    @ApiOperation(value = "Get All Story", response = Story.class)
    @ApiResponses(value = {
            @ApiResponse(code = 200, message = "hello resource found"),
            @ApiResponse(code = 404, message = "Given admin user not found")
    })
    public Response getAllStory(){
        Iterable<Story> stories = storyRepository.findAll();
        LOGGER.info("getAllStory");
        return (stories!=null) ? Response.ok(stories).build() : Response.ok(ResponseErrorGenerator.generate(Response.Status.NOT_FOUND)).status(Response.Status.NOT_FOUND).build();
    }
....

如何制定一種機制來為用戶分配角色，以及如何在令牌中傳遞角色并離散化路由用戶角色?

How I can make a mechanism for assign to user the role and how i can pass the role in token and discretize on route the role of user?

推薦答案

您需要將用戶角色作為附加聲明存儲在 JWT 令牌中，在令牌驗證后提取它們并作為主體的權限"傳遞:

You need to store user roles inside JWT token as additional claims, extract them after token validation and pass as 'authorities' for principal:

 Collection<? extends GrantedAuthority> authorities
                = Arrays.asList(claims.get(AUTHORITIES_KEY).toString().split(",")).stream()
                .map(authority -> new SimpleGrantedAuthority(authority))
                .collect(Collectors.toList());

        User principal = new User(claims.getSubject(), "",
                authorities);

        UsernamePasswordAuthenticationToken t
                = new UsernamePasswordAuthenticationToken(principal, "", authorities);
