2.spring boot aop

二、spring boot aop

1. 创建maven工程

2. 更改工程jdk版本

   <properties>
   	<!-- java版本 -->
   	<java.version>1.8</java.version>
   	<!-- 编译时的编码 -->
   	<maven.compiler.encoding>UTF-8</maven.compiler.encoding>
   </properties>
   <build>
   	<plugins>
   		<plugin>
   			<artifactId>maven-compiler-plugin</artifactId>
   			<configuration>
   				<source>${java.version}</source>
   				<target>${java.version}</target>
   				<encoding>${maven.compiler.encoding}</encoding>
   			</configuration>
   		</plugin>
   	</plugins>
   </build>
   

3. 引入spring boot 父类

   <!-- 引入父类更好的规范各个依赖的version -->
   <parent>
   	<groupId>org.springframework.boot</groupId>
   	<artifactId>spring-boot-starter-parent</artifactId>
   	<version>2.1.0.RELEASE</version>
   </parent>
   

4. 引入依赖

   <dependencies>
   	<dependency>
   		<groupId>org.springframework.boot</groupId>
   		<artifactId>spring-boot-starter</artifactId>
   	</dependency>
   </dependencies>
   <dependency>  
   	<groupId>org.springframework.boot</groupId>  
   	<artifactId>spring-boot-starter-aop</artifactId>  
   </dependency> 
   

5. 创建切面类并且在切面类增加@Aspect 和 @Configuration

   @Before(“execution(* com.chair.springboot.bean..salePhone(…))")
   @After("execution( com.chair.springboot.bean.*.salePhone(…))”)
