如何根据用户删除后台中的按钮操作？我能够通过在canPerform方法中添加一个条件来禁用该按钮，如下所示
public boolean canPerform(final ActionContext<String> ctx)
{
final UserModel currentUser = userService.getCurrentUser();
final boolean isUserMemberOfGroup = this.userService.isMemberOfGroup(currentUser,"group_name");
return isUserMemberOfGroup;
}
但是我想隐藏按钮而不是禁用它。
我希望你已经有一个自定义的后台扩展，如果没有，那么按照本教程创建一个。
现在，在您的自定义后台-后台-配置中.xml您可以使用您希望允许用户/组的操作为您的项目类型声明列表视图操作组件。然后，您需要将该用户的角色/组分配给主体属性。
例如，有两个后台角色"mainRole"和"otherRole"。"mainRole"角色已分配给 X 用户，"otherRole"角色已分配给 Y 用户。现在使用下面的后台配置，X 用户只能看到创建按钮，Y 用户只能看到删除按钮。
<contexttype="Media" component="listviewactions" principal="mainRole" module="hideActionB">
