spring引入@Aspect注解始终爆红，无法引入：

### 排查： ###

步骤1：

查看依赖包：

经过查看已经导入，没有问题

### 步骤2： ###

发现导入的依赖多了一个<scope>runtime</scope>这个：

<scope>runtime</scope>

意思：runtime 是运行的意思。指的是直接在运行时所需要的包，而非在编译时等时候需要的包

### 步骤3： ###

去掉<scope>runtime</scope>

问题解决

## 思考： ##

1.  <scope>官方文档解释

英文原文摘录出来如下：

The scope of the dependency - compile, runtime, test, system, and provided. Used to calculate the various classpaths used for compilation, testing, and so on. It also assists in determining which artifacts to include in a distribution of this project. For more information, see [the dependency mechanism][]. **The default scope is compile**.

默认是编译的

#### **compile，runtime看下官网原文解释：** ####

*  **compile**  
    This is the default scope, used if none is specified. Compile dependencies are available in all classpaths of a project. Furthermore, those dependencies are propagated to dependent projects.

*  **runtime**  
    This scope indicates that the dependency is not required for compilation, but is for execution. Maven includes a dependency with this scope in the runtime and test classpaths, but not the compile classpath.

这个就清晰了，**runtime这个是在运行及测试路径中使用的**

1.  官方依赖为啥会直接添加<scope>runtime</scope>呢?

这个真是个大坑呀，只不过不太明白官方为啥添加这个
