自定义一个注解:
@Documented @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.METHOD) public @interface CommitLog { /** * 类型名称 * @return */ String typeName() ; /** * 方法操作类型 * @return */ String methodName(); }
定义一个日志切面,写入日志信息:
/** * 日志切面 */ @Aspect @Slf4j @Component public class LogAspect { //切点 @Pointcut("@annotation(com.example.demo3.log.CommitLog)") public void PointCut(){ } @Around("LogAspect.PointCut()") public Object methodLogAround(ProceedingJoinPoint proceedingJoinPoint) { MethodSignature signature = (MethodSignature)proceedingJoinPoint.getSignature(); Method method = signature.getMethod(); String className = method.getDeclaringClass().getName();// 类名称 String methodName = method.getName(); // 方法名称 Object[] args = proceedingJoinPoint.getArgs();//参数 // 获取注解信息 CommitLog commitLog=method.getAnnotation(CommitLog.class); String key = commitLog.codeKey(); String type = commitLog.type(); // 调用前 log.info("类名称:{},方法名称{},入参{},注解信息{}",className,methodName,args,commitLog); try { Object proceed = proceedingJoinPoint.proceed(args); } catch (Throwable e) { // e.printStackTrace(); log.info("切面异常"); } // 调用后 log.info("调用前"); // //数据库写入 logMapper.insert(logInfo); return new Object(); } }
提供对外接口,并使用自定义注解:
@Controller public class UserController { @GetMapping("/update") @CommitLog(codeKey = "key1",type = "update") public void update(){ System.out.println("1234567890"); } @GetMapping("/select") @CommitLog(codeKey = "key2",type = "select") public void select(){ System.out.println("1234567890"); } }
