Spring Security当前用户在线程中 [英] spring security current user in thread

问题描述

我在线程范围内使用spring security时遇到了一些问题

hi i have some problems when use spring security in thread scope

System.out.println(((User) SecurityContextHolder.getContext().getAuthentication().getPrincipal()).getId());
new Thread(() -> System.out.println(((User) SecurityContextHolder.getContext().getAuthentication().getPrincipal()).getId())).start();

这两行应该给我当前的用户ID

this two lines should give me current user id

第一行工作正常

第二行给我NullPointerException，因为没有当前用户，它为空值

the second line give me NullPointerException as there is no current user it is null value

我发现此问题是因为我想将许多行保存到歌曲表中，并且拥有@CreatedBy用户，这将要求线程中的当前用户，并且将失败，因为这将为当前用户提供空值

i found this problem as i want to save many rows to the song table and it hava @CreatedBy user and this will ask for current user in thread and will fail as this will give null value for current user

推荐答案

如果您希望生成的线程继承父线程的SecurityContext，则应设置MODE_INHERITABLETHREADLOCAL策略.

If you want spawned threads to inherit SecurityContext of the parent thread, you should set MODE_INHERITABLETHREADLOCAL strategy.
