当我尝试运行docker镜像时,我收到以下错误:

Error response from daemon: Cannot start container {id}: 
[8] System error: open /sys/fs/cgroup/cpu,cpuacct/init.scope/system.slice/docker-{id}.scope/cpu.shares: no such file or directory

/sys/fs/cgroup/cpu,cpuacct/已安装,但没有system.slice目录init.scope

泊坞版:

以下代码段声明了两个具有共同依赖项的 google/wire 初始值设定项。强制只创建一个配置实例的最佳方法是什么？

我可以将共享依赖项传递给 InitializeStorageHandler 函数，但如果我的理解是正确的，这将违背 DI 的目的。

当然，我也可以使用单例模式。我不确定这是否是做事的“Go-Way”。有最佳实践吗？

package api

import (
    "../storage"
    "../config"
    "github.com/google/wire"
)

func InitializeServer() (*Server, error) {
    panic(wire.Build(config.NewConfiguration, NewServer))
}

func InitializeStorageHandler() *StorageHandler {
    panic(wire.Build(config.NewConfiguration, storage.NewStorage, storage.NewService, NewStorageHandler))
}

我试图让一个通用的树支持bean工作.我有一个名为ACLTree的泛型类,然后是它的一个实现.在我的JSF文档中,我尝试按#{mybackingbean.property}访问一个值.但我得到一个ELException:

javax.el.ELException: /modules/useradmin/acl.xhtml @30,55 value="#{ACOTree.root}": java.lang.IllegalAccessException: Class javax.el.BeanELResolver can not access a member of class de.xy.jsf.beans.ACLTree with modifiers "public"

我不太熟悉泛型和反射api的概念,所以也许它根本不可能.

堆栈跟踪:

javax.faces.FacesException: javax.el.ELException: /modules/useradmin/rights.xhtml @30,55 value="#{ACOTree.root}": java.lang.IllegalAccessException: Class javax.el.BeanELResolver can not access a member of class de.xy.jsf.beans.ACLTree with modifiers "public"
