依賴包：
需要依賴包
如果是maven管理專案的，直接pom檔案裡面依賴就可以了，如果是手動下載jar檔案的需要下載aspectjtools.jar
<dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjtools</artifactId>
<version>1.6.10</version>
</dependency>
xml形式的
在spring的配置檔案applicationContext.xml檔案中新增aop
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc" xmlns:aop="http://www.springframework.org/schema/aop"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/jdbchttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop-3.1.xsdhttp://www.springframework.org/schema/jdbc/spring-jdbc.xsd"default-autowire="byName"><aop:config>
