Redundant declaration: @SpringBootApplication already applies given @ComponentScan

这个警告表示`@SpringBootApplication`注解已经包含了`@ComponentScan`注解的功能,因此在同一个类上同时使用这两个注解是多余的。您可以直接使用`@SpringBootApplication`注解,并将其放在主应用程序类上,它将自动扫描主应用程序类所在的包及其子包下的所有组件。
例如,假设您的主应用程序类位于`com.example`包下,您可以这样标记它:
```java
@SpringBootApplication
public class MyApplication {
// ...
}
```
这将自动启用Spring Boot的自动配置,并扫描`com.example`包及其子包下的所有组件。
因此,您无需再使用`@ComponentScan`注解来指定包路径,否则会出现多余声明的警告。如果您需要指定其他包路径或其他配置选项,可以在`@SpringBootApplication`注解中使用其他属性来覆盖默认配置。

As an AI language model, I can't see the code you're referring to. However, based on the error message you provided, it seems that you have declared the `@ComponentScan` annotation along with the `@SpringBootApplication` annotation in your Spring Boot application. The `@SpringBootApplication` already includes the `@ComponentScan` annotation, so declaring it again is redundant.
To fix this issue, you can remove the `@ComponentScan` annotation and keep only the `@SpringBootApplication` annotation. This should not affect your application's functionality since the `@SpringBootApplication` already scans all the components in the current package and its sub-packages.
Avoided redundant navigation to current location: "/test". NavigationDuplicated: Avoided redundant navigation to current location: "/test".
这个错误提示是因为在Vue Router中,当你尝试导航到当前活动的路由时,会抛出NavigationDuplicated错误。这通常是由于重复点击导航链接或在代码中多次调用$router.push('/test')等导航方法引起的。为了避免这个错误,你可以在导航之前检查当前路由是否与要导航的路由相同,如果相同则不进行导航。以下是一个例子:
```javascript
const currentRoute = this.$router.currentRoute;
if (currentRoute.path !== '/test') {
this.$router.push('/test');
}
```
