本文主要记录如何使用aop切面的方式来实现日志记录功能。
主要记录的信息有: 操作人,方法名,参数,运行时间,操作类型(增删改查),详细描述,返回值。
这里只有两个配置:
1)server.port=11000,设置项目启动的端口号,防止被其他服务占用;
2)spring.aop.auto=true,开启spring的aop配置,简单明了,不需要多配置其他的配置或注解。
application.yml文件
server:
port: 11000
spring:
aop:
auto: true #启动aop配置
这个是最主要的类,可以使用自定义注解或针对包名实现AOP增强。
1)这里实现了对自定义注解的环绕增强切点,对使用了自定义注解的方法进行AOP切面处理;
2)对方法运行时间进行监控;
3)对方法名,参数名,参数值,对日志描述的优化处理;
在方法上增加@Aspect 注解声明切面,使用@Pointcut 注解定义切点,标记方法。
使用切点增强的时机注解:@Before,@Around,@AfterReturning,@AfterThrowing,@After

进入方法前执行.....
tel:1234567
记录日志:OperationLog{id='cd4b5ba7-7580-4989-a75e-51703f0dfbfc', createTime=Fri Sep 14 08:54:55 CST 2018, level=3, operationUnit='user', method='com.wwj.springboot.service.impl.UserServiceImpl.findUserName', args='["1234567"]', userId='#{currentUserId}', userName='#{currentUserName}', describe=''#{currentUserName}'=》通过手机号["1234567"]获取用户名', operationType='select', runTime=4, returnValue='"zhangsan"'}
方法最后执行.....
方法的返回值 : zhangsan
