问题：

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
