AspectJ作為語言級(jí)別的AOP框架，功能相比于SpringAOP更加強(qiáng)大。SpringAOP旨在提供給用戶一個(gè)輕量級(jí)的AOP實(shí)現(xiàn)方案，它只能應(yīng)用在SpringIOC容器中管理的bean。而AspectJ旨在提供給用戶一個(gè)完整的AOP解決方案，它可以應(yīng)用在所有的域?qū)ο笾校旅娼o大家介紹SpringBoot使用Aspect切面攔截打印請(qǐng)求參數(shù)的代碼。

引入依賴

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

也用到了fastjson打印參數(shù) ， 如果引了就不需要(也可以根據(jù)自己的來打印)

<!-- 添加fastjson 支持 --><dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.15</version></dependency>
