当 @Scheduled 触发时，在 SecurityContext 中未找到

Question

我创建了一个Spring Boot应用程序，但在某些可以手动或通过@Scheduled注释触发的端点上遇到了问题。我遇到的问题如下：org.springframework.security.authentication.AuthenticationCredentialsNotFoundException：在SecurityContext中找不到身份验证对象SecurityContext如果进程调用 via ，是否有办法触发@Scheduled？我是新手Spring Security，很难理解参考指南。我发现了一些类似的问题，但仍然无法理解如何将答案应用于我的案例。我的例子MyController：@Secured("ROLE_ADMIN")@RestController@RequestMapping(value = "/api")public class MyController {    @Scheduled(cron = "* * * * * *")    @GetMapping(path="/data")    public void getData() {        // Do some operations    }}

Answer 1

基本上，您必须使用必要的身份验证来配置您的调度程序。大致如下：

import com.google.common.collect.ImmutableList;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

import org.springframework.scheduling.annotation.SchedulingConfigurer;

import org.springframework.scheduling.config.ScheduledTaskRegistrar;

import org.springframework.security.authentication.AnonymousAuthenticationToken;

import org.springframework.security.concurrent.DelegatingSecurityContextScheduledExecutorService;

import org.springframework.security.core.authority.SimpleGrantedAuthority;

import org.springframework.security.core.context.SecurityContext;

import java.util.List;

import java.util.concurrent.Executor;

import static java.util.concurrent.Executors.newSingleThreadScheduledExecutor;

import static org.springframework.security.core.context.SecurityContextHolder.getContext;

@Configuration

public class SchedulerConfiguration implements SchedulingConfigurer {

    private static final String KEY = "spring";

    private static final String PRINCIPAL = "spring";

    private static final List<SimpleGrantedAuthority> AUTHORITIES = ImmutableList.of(new SimpleGrantedAuthority("ADMIN"));

    @Override

    public void configureTasks(final ScheduledTaskRegistrar taskRegistrar) {

        taskRegistrar.setScheduler(taskExecutor());

    }

    @Bean

    public Executor taskExecutor() {

        final AnonymousAuthenticationToken token = new AnonymousAuthenticationToken(KEY, PRINCIPAL, AUTHORITIES);

        final SecurityContext securityContext = getContext();

        securityContext.setAuthentication(token);

        return new DelegatingSecurityContextScheduledExecutorService(newSingleThreadScheduledExecutor(), securityContext);

    }

}

然后你可以用 注释你的控制器@Secured("hasAuthority('ADMIN')")。

Answer 2

方法@Scheduled不应该@Secured。预定的方法已经在可信代码中。

重构你的代码，例如

@Secured("ROLE_ADMIN")

@RestController

@RequestMapping(value = "/api")

public class MyController {

    @Autowired

    private MyService myService;

    @PostMapping(path="/run")

    public void runJobs() {

        myService.runJobs();

    }

}

@Service

public class MyService {

    @Scheduled(cron = "* * * * * *")

    public void runJobs() {

        // Do some operations

    }

}
