1.添加切面依赖
<dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.9</version> </dependency>
2.自定义注解
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Log {
String value() default "";
}
3.添加切面
添加component注解自动装配bean到ioc容器中
添加切面注解
@Component
@Aspect
@Slf4j
public class LogAspect {
private final LogService logService;
ThreadLocal<Long> currentTime = new ThreadLocal<>();
public LogAspect(LogService logService) {
this.logService = logService;
}
/**
* 配置切入点，路径为添加自定义注解所在的位置
*/
@Pointcut("@annotation(cn.edu.tsu.torox.sysLog.annotation.Log)")
public void logPointcut() {
// 该方法无方法体,主要为了让同类中其他方法使用此切入点
}
/**
* 配置环绕通知,使用在方法logPointcut()上注册的切入点
*
* @param joinPoint join point for advice
*/
@Around("logPointcut()")
public Object logAround(ProceedingJoinPoint joinPoint) throws Throwable {
Object result;
currentTime.set(System.currentTimeMillis());
result = joinPoint.proceed();
cn.edu.tsu.torox.sysLog.model.Log log = new cn.edu.tsu.torox.sysLog.model.Log("INFO",System.currentTimeMillis() - currentTime.get());
currentTime.remove();
// String request = RequestHolder.getHttpServletRequest();
//业务类，根据需求定义，这里为日志，提前建表，进行crud
logService.save("1", "google", "192.168.231.20",joinPoint, log);
return result;
}
/**
* 配置异常通知
*
* @param joinPoint join point for advice
* @param e exception
*/
@AfterThrowing(pointcut = "logPointcut()", throwing = "e")
public void logAfterThrowing(JoinPoint joinPoint, Throwable e) {
cn.edu.tsu.torox.sysLog.model.Log log = new cn.edu.tsu.torox.sysLog.model.Log("ERROR",System.currentTimeMillis() - currentTime.get());
currentTime.remove();;
// HttpServletRequest request = RequestHolder.getHttpServletRequest();
logService.save("1", "google", "192.168.231.20", (ProceedingJoinPoint)joinPoint, log);
}
}
4.具体详细参数在joinPoint对象中
5.将自定义注解添加到相应的控制层方法上
流程：
接口-->控制层--->找到带有自定义注解的方法---->跳入切面--->执行环绕通知中的方法（获取该类的方法）
依赖：若项目使用的数据层技术为Spring-data-jpa则无须单独引入aspectjweaver依赖。
