代码如下:

package mscontroller;

import javax.swing.*;
import com.apple.eawt.Application;

public class Main {
    public static void main(String[] args)
    {
        Application app = new Application();
        app.setEnabledAboutMenu(true);

        AMEListener listener = new AMEListener();
        app.addApplicationListener(listener);
        JFrame mainFrame = new JFrame("Application Menu Example");
        mainFrame.setSize(500, 500);
        mainFrame.setVisible(true);
    }
}

错误如下:

Eclipse说:

访问限制:'Application'类型不是API(对必需库'/ library /Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home/jre/lib/rt.jar'的限制)


当前回答

我遇到了一个不同的问题。在项目-属性-库- JRE库,我有错误的JRE库版本。删除并设置实际的一个,瞧——所有的访问限制…警告消失了。

其他回答

对我有用的是将访问限制包添加到MANIFEST中。MF文件。在Eclipse中,“Access Restricted”错误显示在几个文件的Problems选项卡中。我只是右键点击每个错误,点击“快速修复”,并选择“添加[包]到导入的包”。

我只是简单地在eclipse市场中添加e(fx)clipse。简单明了

在Eclipse顶部菜单栏中:

Windows -> Preferences -> Java -> Compiler -> Errors/Warnings -> 
Deprecated and restricted API -> Forbidden reference (access rules): -> change to warning

删除现有/配置的系统库: Eclipse(IDE) -> Project Explorer -> Project Name-> (Option) Build Path -> Configure Build Path -> Java Build Path -> Libraries -> (Select) JRE System Library [(For me)jre1.8.0_231] -> Remove。

目前你在同一位置: Eclipse(IDE) ->项目资源管理器->项目名称->(选项)构建路径->配置构建路径-> Java构建路径->库

现在再次添加相同的系统库: Add Library -> JRE System Library -> Workspace default JRE ((For me)jre1.8.0_231) -> Finish -> Apply -> Close

现在等着完成它。

我们使用IBM Rational Application Developer (RAD),也遇到了同样的问题。

ErrorMessage:

访问限制:'JAXWSProperties'类型不是API(对必需库'C:\IBM\RAD95\jdk\jre\lib\rt.jar'的限制)

解决方案:

进入java构建路径,在Library标签下,删除JRE System Library。然后再次添加库—> JRE系统库
