您可以 Package 由DelegatingSecurityContextRunnable提交给Jobrunr的Runnable
它要求您定义SecurityContext以运行Runnable，并且它将负责在运行任务之前和之后设置和清理SecurityContext。
在配置SecurityContext时，最好与现有使用的身份验证机制保持一致，以定义一个具有足够权限来运行作业的Authentication对象。
下面是一个入门示例：

//origin runnable task submitted to Jobrunr
Runnable task = () -> System.out.println("doing some task");

//Configure the SecurityContext that has enough permission to execute the task

SecurityContext securityContext = SecurityContextHolder.createEmptyContext();
List<GrantedAuthority> grantedAuthorities = new ArrayList<>();
grantedAuthorities.add(new SimpleGrantedAuthority("ROLE_ADMIN"));
// Here it does not matter what values username and password are. Just ensure this user has the the Admin GrantedAuthority and his account is enabled
User user = new User("admin", "password", true, true, true, true, grantedAuthorities);
Authentication authentication = new UsernamePasswordAuthenticationToken(user, user.getPassword(), user.getAuthorities());
securityContext.setAuthentication(authentication);

//wrap the task by DelegatingSecurityContextRunnable
DelegatingSecurityContextRunnable securedRunnable = new DelegatingSecurityContextRunnable(task,securityContext);

//Submit the secured task to Jobrunr
BackgroundJob.enqueue(securedRunnable);
