项目中遇到多个模块需要打印Controller请求日志，在每个模块里面加AOP并且配置单独的切面笔者认为代码冗余，于是乎就打算把AOP日志打印抽离成一个公共模块，谁想用就引入Maven坐标就行。
定义公共AOP模块 并编写AOP工具
AOP模块pom.xml如下
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://maven.apache.org/POM/4.0.0"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<parent>
这里根据自己需要引入 公共AOP父模块

@Pointcut(“execution(public * com.ruoyi..controller..*(…))”) 作为AOP切入口
此切入口必须为静态常量 不能为动态参数 所以说从yml读取切入点是干不成。
但 @Pointcut 可以同时配置多个参数 这个就可以解决多个不同路径下面的Controller都能被切入进来。
@Pointcut("execution(* xx.xx.xxx.xx.*.save*(..))"
+ "||execution(* xx.xx.xx.*.delete*(..))"
+ "||execution(* xx.xx.xx..*.update*(..))")
子模块
-
使用需要引入公共AOP模块maven
-
创建图片中目录文件 并引入公共模块定义好的ServiceLogAop ( 这里也可以通过 @Bean方式把ServiceLogAop 注册进来 )
-
效果
