@PreAuthorize无法与prePostEnabled = true一起使用

Question

似乎使用

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
}

@PreAuthorized无效：

@PreAuthorize("permitAll()")
@RequestMapping(value = "/users/change-email", method = RequestMethod.GET)
public void changeEmail() {
    // ..
}

我也有@EnableGlobalMethodSecurity(prePostEnabled = true)，结果相同：

@PreAuthorize("permitAll()")
@Transactional
public void changeEmail(HttpServletResponse response, String token) throws IOException {
     // ..
}

我不清楚为什么-有任何想法吗？

这就是我配置ResourceServerConfigurerAdapter的方式：

@Configuration
@EnableResourceServer
public class ResourceServer extends ResourceServerConfigurerAdapter {

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

        http
                .exceptionHandling()
                    .authenticationEntryPoint(new AuthFailureHandler())
                .and()
                .authorizeRequests()
                    .anyRequest()
                    .authenticated();
    }
}

此刻我得到一个AccessDeniedException：
