Spring Boot：禁用状态异常代码的安全性

Question

@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    private final JwtFilter jwtFilter;

    @Autowired
    public SecurityConfiguration(JwtFilter jwtFilter) {
        this.jwtFilter = jwtFilter;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
                .anonymous().and()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
                .authorizeRequests()
                .anyRequest().authenticated().and()
                .apply(new JwtConfigurerAdapter(jwtFilter)).and()
                .exceptionHandling().authenticationEntryPoint(new HttpStatusEntryPoint(HttpStatus.UNAUTHORIZED));
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/v2/api-docs");
        web.ignoring().antMatchers("/login");
    }
}

@ResponseStatus(value = HttpStatus.NOT_FOUND)
public class NotFound extends RuntimeException {
    public NotFound(String message) {
        super(message);
    }
}

@RestController
public class LoginController implements LoginService {
    @Override
    @GetMapping(value = "/login", produces = MediaType.APPLICATION_JSON_VALUE)
    public UserInfo loginUsingJson(String username, String password) {
        return findUser(username, password)).orElseThrow(() -> new NotFound("There does not exist any user by those credentials"));
    }
}

我猜这与HttpSecurity有关，在这里我必须添加一些异常或其他东西，以便返回异常代码。但是我在什么地方允许在HttpSecurity的授权中忽略异常处理呢？

Answer 1

我找到了答案，并愿意帮助处于同样处境的其他人。

我的问题是，当返回错误代码404 NotFound的rest异常时，Spring Boot会自动重定向到url“/error”。但这个url映射需要打开用于业务。所以我不得不忽略这个url的授权。

这里的解决方案是添加以下内容：

web.ignoring().antMatchers("/error");

@Configuration
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    private final JwtFilter jwtFilter;

    @Autowired
    public SecurityConfiguration(JwtFilter jwtFilter) {
        this.jwtFilter = jwtFilter;
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
                .anonymous().and()
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
                .authorizeRequests()
                .anyRequest().authenticated().and()
                .apply(new JwtConfigurerAdapter(jwtFilter)).and()
                .exceptionHandling().authenticationEntryPoint(new HttpStatusEntryPoint(HttpStatus.UNAUTHORIZED));
    }

    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/v2/api-docs");
        web.ignoring().antMatchers("/login");
        web.ignoring().antMatchers("/error");
    }
}
