我正在尝试配置 spring boot 以将 mongoDB 用于存储用户和 session 。我可以存储用户和 session ，但在不同的项目中，当我将它们放在同一个项目中时，SessionRepositoryFilter 的Autowired 失败。

错误在这里:

我不知道怎么解决的:

原因:org.springframework.beans.factory.BeanCurrentlyInCreationException:创建名为“sessionRepositoryFilter”的 bean 时出错:当前正在创建请求的 bean:是否存在无法解析的循环引用？

配置文件是:

最佳答案

在这部分代码中删除对 this.sessionSessionRepositoryFilter 的分配，因为 Spring 会自动为您分配。

    @Bean
    public SessionRepositoryFilter<ExpiringSession> sessionRepositoryFilter(
            SessionRepository<ExpiringSession> sessionRepository,
            HttpSessionStrategy httpSessionStrategy
    ) {
        SessionRepositoryFilter<ExpiringSession> sessionRepositoryFilter = new SessionRepositoryFilter<>(sessionRepository);
        sessionRepositoryFilter.setHttpSessionStrategy(httpSessionStrategy);
        this.sessionSessionRepositoryFilter = sessionRepositoryFilter; //Remove this.
        return sessionRepositoryFilter;
    }

关于java - spring boot 用户和 session mongo，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41890332/
