为什么 ng new newApp 生成无法解决依赖树错误

我正在尝试使用命令创建一个新的 angular 应用程序 ng new app-name.. 但运行该命令后,它在命令行中显示以下内容。

关闭嵌套堆栈导航器

在我的反应本机项目中,我正在使用库

"@react-navigation/native": "^5.8.10",
"@react-navigation/stack": "^5.12.8",

我有嵌套的导航器,如下所示:

// root level I have a stack navigator where it contains two screens, `Home` and `Settings`.
const App = ()=> {
  const rootStack = createStackNavigator();
  return (
    <NavigationContainer>
      <rootStack.Navigator>
        <rootStack.Screen name="Home" component={Home} />
        <rootStack.Screen name="Settings" component={Settings} />
      </rootStack.Navigator>
    </NavigationContainer>
  );
}

// The Settings screen is a nested stack navigator
const Settings = ()=> {
  const settingsStack = createStackNavigator();
  return (
    <settingsStack.Navigator>
      <settingsStack.Screen name="SettingsOne" component={SettingsOneScreen} />
      <settingsStack.Screen name="SettingsTwo" component={SettingsTwoScreen} />
    </settingsStack.Navigator>
  );
}

正如您所看到的,“设置”屏幕实际上是另一个级别(嵌套)堆栈导航器。 …

为什么实体类显示 pmd 警告“类被怀疑是 DataClass”

我有一个用户类,如下所示

@Entity
public class User {
     @Id
     @GeneratedValue
     private Long primaryKey;
     private String name;
     // some other fields, default constructor, All argument constructor, 
     // getters and setters

当我使用 PMD 代码分析器进行分析时,它显示the class User suspected to be a DataClass.

我尝试使用UserDataClass该类的命名,但它仍然显示此警告。

我们可以遵循什么命名约定来消除此警告?
