【Spring】使用注解开发前提条件

前提：导入约束，添加注解支持

"1.0" encoding="UTF-8"?>
"http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation=" http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans.xsd
             http://www.springframework.org/schema/context
             http://www.springframework.org/schema/context/spring-context.xsd">
 
 
    
 
 

如果spring项目是用maven创建的

相关依赖

  
    org.springframework
    spring-webmvc
    5.3.30
  

  
    junit
    junit
    3.8.1
    test
  

spring4之后要保证aop的依赖导入
