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)

我也有同样的问题。以下是我的解决方法: 进入包资源管理器。右键单击JRE系统库,然后进入属性。在类路径容器>中为项目构建路径选择JRE,选择第三个选项(工作区默认JRE)。

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

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

在eclipse oxygen中添加javafx可访问权限 进入项目>属性> java构建路径> libraries>,然后展开库,双击>访问规则,在那里设置权限 解决方案:无障碍 规则模式:javafx/**

进入以下设置:

窗口->首选项-> java -编译器-错误/警告-弃用和限制api -禁止引用(访问规则)

设置为“警告”或“忽略”。

它工作:项目属性-> ProjectFacets ->运行时-> jdk1.8.0_45 ->应用
