如何在Java模块中指定源和目标兼容性？(How to specify source and target compatibility in Java module?)

 在我做了搜索，并且找不到答案之后，我对此有了更多的考虑，这是我提出的解决方案（只是对其他人有用） ： 
 
 Psuedo第一： 
 
 
 
 显示一个页面，列出ACL $acl->getRoles()中的所有角色 （用户级别 $acl->getRoles()作为链接。 
 
 
 单击链接，重新加载将角色作为参数传递的页面。 
  
 
   
 现在从ACL $acl->getResources()获取所有控制器 ，检查资源不是一个角色（getResources返回的数组也将包含角色） 。 
 
   
 循环遍历每个控制器 ，从规则表中获取控制器 id在resource_id字段中的所有条目并爆炸额外内容 （逗号分隔操作） 
 
   
 接下来，遍历每个动作 ，调用isAllowed （我有角色，控制器和动作） 。 如果找到至少一个“允许”，我将控制器设置为绿色（允许访问控制器中的至少一个操作） ，否则其红色（不能访问该控制器中的任何内容）每个列表项都可单击以重新加载页面 
 
  
 
 
 现在，当单击控制器时，我重新加载页面，现在，当运行操作列表时，调用isAllowed我创建所选控制器的操作列表，根据isAllowed的结果将操作着色为绿色或红色 
 
 
 它的自我答案几乎和问题一样冗长，但它对我有用，可以清楚地了解每个角色可以做些什么。 在这里它是否会帮助任何人： 
 
 现在代码： 
 
 AdminController：

 我希望这对某人有帮助，我会暂时保持开放状态，任何人都可以提出更好的解决方案 - 或者可以改进答案？ 

Well after I did abit of searching, and couldn't find an answer, I had a bit more of a think about this and here is the solution I came up with (just incase its useful for someone else):
 
Psuedo first:
 
 
 
Show a page, listing all of the roles (user levels) from the ACL $acl->getRoles() as a link.
 
 
Click a link, reload the page passing the role as a parameter. 
  
 
   
Now grab all the controllers from ACL $acl->getResources() checking that the resource insn't a role (the array returned by getResources will also contain the roles).
 
   
loop through each controller, get all entries from the rules table where the controller id is in the resource_id field and explode the extras (comma seperated actions)
 
   
Next, loop through each action, calling isAllowed (I have the role, controller, and action). IF at least one "allowed" is found, I colour the controller green (allowed access to at least one action in the controller), otherwise its red (no access to anything in that controller) each list item being clickable to reload the page
 
  
 
 
Now when a controller is clicked, I reload the page, now, when running through the list of actions, calling isAllowed I create a list of the actions for the selected controller, colouring the action green or red based on the result of isAllowed
 
 
The answer its self is almost as long winded as the question, but it works for me, giving a very clear picture of what each role can do. Here it is if its going to help anyone:
 
Now for the code:
 
AdminController:
 
public function aclAction()
{
    $this->view->content_title = "Access Rules:";

    // Get the ACL - its stored in the session:
    $usersNs = new Zend_Session_Namespace("ZEND_SITE");
    $acl = $usersNs->acl;

    // List all Roles in the ACL:
    $roles = $acl->getRoles();
    // Pass the roles to the view:
    $this->view->roles = $roles;

    // Check if a role has been clicked on:
    $role = this->_getParam('role');
    if(!is_null($role))
    {
        // Pass the role to the view:
        $this->view->role = $role;

        // Get all the resources (controllers) from the ACL, don't add roles:
        $controllers = array();
        foreach ($acl->getResources() as $res)
        {
            if (!in_array($res, $roles))
            {
                $controllers[] = $res;
            }
        }

        // Create a Rules Model:
        $rules = new Model_ACLrules();

        // Store controllers + access:
        $all_controllers = array();

        // Check if the controller has been passed:
        $cont = $this->_getParam('cont');

        // Loop through each controller:
        foreach ($controllers as $controller)
        {
            // Get all actions for the controller:
            // THIS IS THE PART I DON'T LIKE - BUT I SEE NO WAY TO GET
            // THE RULES FROM THE ACL - THERE LOOKS TO BE A METHOD
            // BUT IT IS A PROTECTED METHOD - SO I AM GETTING THE ACTIONS

            // Store if the role is allowed access somewhere in the controller:
            $allowed = false;

            // Store selected controller actions:
            $cont_actions = array();

            // Loop through all returned row of actions for the resource:
            foreach ($all_rules as $rule)
            {
                // Split the extras field:
                $extras = explode(",", $rule->extras); 

                // Check if the role has access to any of the actions:
                foreach ($extras as $act)
                {
                    // Store matching selected controller:

                    // Store the action if we are looking at a resource:
                    if ($match)$temp = array("action"=>$act,"allowed"=>false);

                    // Check if the role is allowed:
                    if ($acl->isAllowed($role,$controller,$act))
                    {
                        // Change the controllers allowed to ture as at least one item is allowed:
                        $allowed = true;

                        // Change the matched controllers action to true:
                        if ($match)$temp = array("action"=>$act,"allowed"=>true);
                    }

                    // Check if the action has already been added if we are looking at a resource:
                    if ($match)
                    {
                        $add = true;
                        // This is done because there could be several rows of extras, for example
                        // login is allowed for guest, then on another row login is denied for member,

                        // no point in showing login action twice:
                        foreach ($cont_actions as $a)
                        {
                            // Action already in the array, don't add it again:
                            if ($a['action'] == $act) $add = false;
                        }
                        if($add) $cont_actions[] = $temp;
                    }
                }
            }

            // Pass a list of controllers to the view:
            $all_controllers[] = array("controller" => $controller, "allowed" => $allowed);

            // Check if we had a controller:
            if(!is_null($cont))
            {
                // Pass the selected controller to the view:
                $this->view->controller = $cont;

                // Check if this controller in the loop is the controller selected:
                if ($cont == $controller)
                {
                    // Add the controller + actions to the all rules:
                    $this->view->actions = $cont_actions;

        }

        // Pass the full controller list to the view:
        $this->view->controllers = $all_controllers;
    }   
}
 
Next the view: acl.phtml:
