为什么使用 @Autowired 进行 set 注入会出现概率失败问题

[qiaofanxing]

我看有人说，set 注入不推荐使用 @Autowired ，所以我想分别测试一下 @Autowired 和 @Resource 。 结果使用 @Autowired 进行注入会出现概率失败，大概每三四次就失败一次的样子，为什么会这样呢？真有问题不应该每一次都报错吗。

这里是代码

@Configuration
@EnableWebSecurity
public class AuthManagerConfig {

    private MyUserService myUserService;

    @Autowired
    public void setMyUserService(MyUserService myUserService) {
        this.myUserService = myUserService;
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(myUserService);
    }

}

这里是随机出现的异常
