mylog 自定义注解打印 logger

Posted 2022-07-15 lshan

使用ＡＯＰ 自动打印方法进出，　耗时 logger

 

依赖：

　 　<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <optional>true</optional>
 　　</dependency>

　　<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
   </dependency>

 

注解：

/**
 * *************************************************************************
 * <PRE>
 *  @ClassName:    : Mylog 
 *
 *  @Description:    : 自定义注解, 实现对方法的进 出 ,运行时间 打印logger,
 *
 *  @Creation Date   : 8 Aug 2019 3:02:36 PM
 *
 *  @Author          :  Sea

 * </PRE>
 **************************************************************************
 */
@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface Mylog  
    String value() default "";

 

 

 

切片：

@Aspect
@Component
public class MylogAspect 

    private static Logger logger = LoggerFactory.getLogger(MylogAspect.class);


    @Around("@annotation(Mylog)") // 作用到注释@Mylog标记的方法上
    public Object handleSeaAnnotionAOPMethod(ProceedingJoinPoint joinPoint, Mylog Mylog) throws Throwable 

        long start = System.currentTimeMillis();
        // 获取方法的 全类名 com.sea.controller.XXXcontroller.getdate()
        MethodSignature signature = (MethodSignature) joinPoint.getSignature();
        String className = signature.getDeclaringType().getSimpleName();

        // 获取注解作用方法名 eg:getdata
        String methodName = joinPoint.getSignature().getName();

        // 获取方法--
//                 Method method = joinPoint.getTarget().getClass().getMethod(methodName, signature.getParameterTypes());
//                 Method method = getMethod(joinPoint);

        logger.info("&&&&&& enter into the class  -> method  &&&&&&", className, methodName);

        // ################################################################
        Object object = joinPoint.proceed();

        System.err.println(className);
        long end = System.currentTimeMillis();
        logger.info("&&&&&& end  the class  -> method  &&&&&&", className, methodName);
        logger.info(" ^^^^^^^^^run the  method  total cost time :   ms ^^^^^^^^",methodName, (end - start));
        return object;
    

 

 

Test:

    @GetMapping("/get")
    @Mylog
     public String getData() 
        
        
         return "nihao"+ UUID.randomUUID();
    
    

 

结果:  .....
