java 继承类之后，访问不到超类的属性的原因及解决方法

是因为超类里的属性没有加上public关键字

解决方法：超类和超类里的属性或者方法如果想被其他包下的方法调用，就必须全部加上public权限，即设置为公开访问

例：

@Controller
public class BaseController {

    @Autowired
    public AssetsService assetsService;
    @Autowired
    public ConfigLinuxService configLinuxService;
    @Autowired
    public ConfigWindowsService configWindowsService;
    @Autowired
    public XconfigLinuxService xconfigLinuxService;
    @Autowired
    public XconfigWindowsService xconfigWindowsService;
    @Autowired
    public ConfigWindowsWaiYunService configWindowsWaiYunService;

}

public class BaseUtil {

    public AssetsService assetsService = (AssetsService) SpringContextUtil.getBean(AssetsService.class);
    public ConfigLinuxService configLinuxService = (ConfigLinuxService) SpringContextUtil.getBean(ConfigLinuxService.class);
    public ConfigWindowsService configWindowsService = (ConfigWindowsService) SpringContextUtil.getBean(ConfigWindowsService.class);
    public XconfigLinuxService xconfigLinuxService = (XconfigLinuxService) SpringContextUtil.getBean(XconfigLinuxService.class);
    public XconfigWindowsService xconfigWindowsService = (XconfigWindowsService) SpringContextUtil.getBean(XconfigWindowsService.class);

}
