这段代码定义了一个使用Hilt依赖注入的ViewModel。使用@HiltViewModel注释标记的类将自动由Hilt为其提供依赖项。
在这个例子中,AddressViewModel类需要一个AddressRepository对象来执行某些操作。使用@Inject注释标记的构造函数告诉Hilt为AddressRepository提供依赖项。当需要创建AddressViewModel对象时,Hilt将自动为它提供一个AddressRepository对象作为构造函数的参数。
需要注意的是,使用Hilt时,你需要在你的应用程序中配置Hilt,并设置正确的依赖项。这通常需要一些学习和实践,但一旦你理解了它的工作原理,就可以大大提高你的代码质量和开发效率。
另外,这段代码还继承了一个BaseViewModel类,可能是你自己定义的一个ViewModel基类,用于提供通用的ViewModel功能和逻辑。

@autowired和@resource区别 inject
@Autowire和@Resource都是在Spring框架中用于自动注入依赖的注解,但它们有一些区别。
1. @Autowired注解是Spring的核心注解之一,它可以用于自动注入依赖关系。它根据类型进行注入,并且默认情况下要求依赖的bean必须存在,否则会抛出异常。如果有多个匹配的bean,则可以通过设置@Qualifier注解来指定具体的bean。
2. @Resource注解是Java EE的标准注解之一,也可以用于自动注入依赖关系。它可以根据名称进行注入,并且默认情况下要求依赖的bean必须存在,否则会抛出异常。如果有多个匹配的bean,则可以通过设置name属性来指定具体的bean。
总结来说,@Autowired是Spring的注解,更加灵活,可以根据类型进行注入,而@Resource是Java EE的注解,更加标准化,可以根据名称进行注入。在实际使用中,可以根据具体的需求选择使用哪个注解。
Could not write JSON: You used the annotation `@FieldSensitive` but did not inject `SensitiveStrategy`
As an AI language model, I do not have access to the specific code you are working on. However, based on the error message you provided, it seems that you are using the `@FieldSensitive` annotation in your code but have not injected the `SensitiveStrategy` that is required for this annotation.
The `@FieldSensitive` annotation is usually used to mark a field as sensitive and requires a `SensitiveStrategy` to be injected. This strategy is responsible for determining how the sensitive data should be handled, such as whether it should be encrypted or masked.
To fix this error, you should inject the `SensitiveStrategy` that is needed for the `@FieldSensitive` annotation. You can do this by creating a bean for the `SensitiveStrategy` in your application context and then injecting it into the class where the annotation is used.
For example:
```
@Configuration
public class AppConfig {
@Bean
public SensitiveStrategy sensitiveStrategy() {
// create and return the SensitiveStrategy implementation
}
}
public class MyClass {
@Autowired
private SensitiveStrategy sensitiveStrategy;
@FieldSensitive
private String sensitiveField;
// rest of the class
}
```
In this example, we create a bean for the `SensitiveStrategy` in the `AppConfig` class and then inject it into the `MyClass` class where the `@FieldSensitive` annotation is used. This should resolve the error you are seeing.
