在网站后台备案号怎么改/网络营销方案模板

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</parent><modelVersion>4.0.0</modelVersion><artifactId>xx-common-aop</artifactId><description>xx-common-aop切面</description><dependencies><!-- Lombok --><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency><!-- SLF4J --><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId></dependency><dependency><groupId>org.springframework.cloud</groupId><artifactId>spring-cloud-starter-bootstrap</artifactId></dependency><!-- FastJSON --><dependency><groupId>com.alibaba.fastjson2</groupId><artifactId>fastjson2</artifactId></dependency><!-- Hutool --><dependency><groupId>cn.hutool</groupId><artifactId>hutool-all</artifactId></dependency><dependency><groupId>org.aspectj</groupId><artifactId>aspectjweaver</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency></dependencies></project>

@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

1. 使用需要引入公共AOP模块maven

2. 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 )
   

3. 效果
