我主要是在@IocBean 服务里面,需要调用Spring下定义的服务,解决用@Inject无效报错的问题
按照提示这样设置:

@AdaptBy(type = JsonAdaptor.class)
@IocBean(create = "init")
@Slf4j
@Modules(scanPackage = true)
@IocBy(args={
        "*js", "ioc/",
        "*anno", "com.podiy",
        "*spring"
})
public class MainLauncher {}

编译启动报错:

这种操作很少见了吧

是呀,不得已呀,spring类里面也是嵌入引用,如果直接new的话,类里面的类都是null,而且嵌套了好几层,只有通过从spring中读出才能正常

把对象存到static变量里, 就不必走ioc了
