本文实例为大家分享了springboot实现基于aop的切面日志的具体代码，供大家参考，具体内容如下
通过aop的切面方式实现日志
通切面拦截所有指定包下的所有方法
@Aspect
@Component
@EnableAspectJAutoProxy
public class LogAspect1{
Logger logger = LoggerFactory.getLogger(LogAspect.class);
@Pointcut("execution(*xx.xx.controller.*.*(..))")
private void logPointCut() {
logger.info("进入注解拦截");
}
//前置通知，在方法之前通知
@Before(value = "logPointCut()")
public void before(JoinPoint jp) {
logger.info("方法调用前：" + "类名:" + jp.getTarget().getClass().getName() + "方法名 :" + jp.getSignature().getName());
}
//后置通知
@After(value = "logPointCut()")
public void doAfter(JoinPoint jp) {
logger.info("方法调用结束：" + "类名:" + jp.getTarget().getClass().getName() + "方法名 :" + jp.getSignature().getName());
}
//环绕通知
@Around("logPointCut()")
public Object doAround(ProceedingJoinPoint pjp) throws Throwable {
logger.info("方法开始调用》》》》》》");
Object retVal = pjp.proceed();
logger.info("方法调用结束》》》》》》");
return retVal;
}
//返回通知
@AfterReturning(pointcut = "logPointCut()")
public void doAfterReturning(JoinPoint jp) {
logger.info("写入日志");
}
//异常通知
@AfterThrowing(pointcut = "logPointCut()", throwing = "ex")
public void doAfterThrowing(JoinPoint jp, Throwable ex) {
logger.info("方法异常，异常信息：" + ex.getMessage());
}
}拦截自定义注解
定义一个日志注解，在所有要需要记录的方法上加盖注解即可被后续的aop拦截处理
代码如下
@Target({ElementType.PARAMETER, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Log {
public String title() default "";
public String business() default "";
public boolean isSaveRequestData() default false;
LogType logType() default LogType.LOGIN;
}拦截切面的实现
@Aspect
@Component
@EnableAspectJAutoProxy
public class LogAspect {
Logger logger = LoggerFactory.getLogger(LogAspect.class);
@Autowired
private ServiceDemo serviceDemo;
@Pointcut("@annotation(moling.evolution.demo.aop.annotation.Log)")
private void logPointCut() {
}
//前置通知，在方法之前通知
@Before(value = "logPointCut()")
public void before(JoinPoint jp) {
logger.info("方法调用前：" + "类名:" + jp.getTarget().getClass().getName() + "方法名 :" + jp.getSignature().getName());
}
//后置通知
@After(value = "logPointCut()")
public void doAfter(JoinPoint jp) {
logger.info("方法参数：{}", jp.getArgs());
logger.info(" {} || {}", jp.getStaticPart().getId(), jp.getStaticPart().getSourceLocation());
jp.getStaticPart().getId();
logger.info("方法调用结束：" + "类名:" + jp.getTarget().getClass().getName() + "方法名 :" + jp.getSignature().getName());
}
//环绕通知
@Around("logPointCut()")
public Object doAround(ProceedingJoinPoint pjp) throws Throwable {
logger.info("方法开始调用》》》》》》");
Object retVal = pjp.proceed();
logger.info("方法调用结束》》》》》》");
return retVal;
}
//返回通知
@AfterReturning(pointcut = "logPointCut()", returning = "object")
public void doAfterReturning(JoinPoint jp, Object object) {
System.out.println("返回通知");
Log log = null;
try {
log = getAnnotationLog(jp);
} catch (Exception e) {
e.printStackTrace();
}
System.out.println(object);
System.out.println(log);
if (log != null) {
logger.info(log.title());
logger.info(log.business());
logger.info(log.user());
logger.info(log.isSaveRequestData() + "");
} else {
logger.error("获取注解信息失败");
}
serviceDemo.demo();
}
//异常通知
@AfterThrowing(pointcut = "logPointCut()", throwing = "ex")
public void doAfterThrowing(JoinPoint jp, Throwable ex) {
logger.info("方法异常，异常信息：" + ex.getMessage());
serviceDemo.error();
}
private Log getAnnotationLog(JoinPoint joinPoint) throws Exception {
Signature signature = joinPoint.getSignature();
MethodSignature methodSignature = (MethodSignature) signature;
Method method = methodSignature.getMethod();
if (method != null) {
return method.getAnnotation(Log.class);
}
return null;
}
}基于事件通知实现日志的记录
- 拦截切面的实现
@Aspect
@Component
@EnableAspectJAutoProxy
public class LogAspectContext {
Logger logger = LoggerFactory.getLogger(LogAspectContext.class);
@Autowired
private ApplicationContext applicationContext;
@Pointcut("@annotation(moling.evolution.demo.aop.annotation.Log)")
private void logPointCut() {
logger.info("进入注解拦截");
}
//返回通知
@AfterReturning(pointcut = "logPointCut()", returning = "object")
public void doAfterReturning(JoinPoint jp, Object object) throws Exception {
applicationContext.publishEvent(new LogSuccessEvent(jp, null));
}
//异常通知
@AfterThrowing(pointcut = "logPointCut()", throwing = "ex")
public void doAfterThrowing(JoinPoint jp, Throwable ex) {
logger.info("方法异常，异常信息：" + ex.getMessage());
applicationContext.publishEvent(new LogSuccessEvent(jp, ex));
}
private Log getAnnotationLog(JoinPoint joinPoint) throws Exception {
Signature signature = joinPoint.getSignature();
MethodSignature methodSignature = (MethodSignature) signature;
Method method = methodSignature.getMethod();
if (method != null) {
return method.getAnnotation(Log.class);
}
return null;
}
}@Slf4j
@Service
public class ApplicationListener implements org.springframework.context.ApplicationListener<LogSuccessEvent> {
@Autowired
private ServiceDemo demo;
@Override
public void onApplicationEvent(LogSuccessEvent event) {
JoinPoint joinPoint = event.getJp();
Throwable ex = event.getThrowable();
if (ex == null) {
demo.demo();
} else {
demo.error();
}
}
}@Slf4j
public class LogSuccessEvent extends ApplicationEvent {
private JoinPoint jp;
private Throwable throwable;
public LogSuccessEvent(Object source, Throwable throwable) {
super(source);
this.throwable = throwable;
this.jp = (JoinPoint) source;
// Log logger = (Log) source;
// log.info(logger.title());
// log.info(logger.business());
// log.info(logger.user());
// log.info(logger.isSaveRequestData() + "");
}
public JoinPoint getJp() {
return jp;
}
public Throwable getThrowable() {
return throwable;
}
