spring切面打印日志

　　基本思路 日志注解 日志切面 获取切面中参数值和返回值 基本思路
　　用AOP的around实现，注解+切面 日志注解package com.annotion;   import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target;  @Target({ElementType.METHOD}) @Retention(RetentionPolicy.RUNTIME) public @interface FuncMethodLog {  }  日志切面package com.aspect;  import lombok.SneakyThrows; import lombok.extern.slf4j.Slf4j; import org.apache.commons.lang3.ArrayUtils; import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation.Aspect; import org.aspectj.lang.reflect.MethodSignature; import org.springframework.stereotype.Component;  import java.lang.reflect.Method; import java.lang.reflect.Parameter;  @Aspect @Component @Slf4j public class FuncMethodLogAspect {      @SneakyThrows     @Around(＂@annotation(com.ccbscf.biz.zdw.annotion.FuncMethodLog)＂)     private Object around(ProceedingJoinPoint joinPoint) {         MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();         Method targetMethod = methodSignature.getMethod();         log.info(＂MethodLog before, class name:{}, method name:{}＂, targetMethod.getDeclaringClass(), targetMethod.getName());         Parameter[] parameters = targetMethod.getParameters();         Class<?>[] parameterTypes = targetMethod.getParameterTypes();         Object[] args = joinPoint.getArgs();         if (ArrayUtils.isNotEmpty(args)) {             for (int i = 0; i < args.length; i++) {                 log.info(＂MethodLog processing, parameter: {} => {}＂, parameterTypes[i], args[i]);             }         }         Object rvt = joinPoint.proceed(args);         log.info(＂MethodLog after, method return value: {}＂, rvt);         return rvt;     }  }   获取切面中参数值和返回值//获取参数名和参数值 public void getParam(ProceedingJoinPoint proceedingJoinPoint) {     Map map = new HashMap();     Object[] values = proceedingJoinPoint.getArgs();     String[] names = ((CodeSignature) proceedingJoinPoint.getSignature()).getParameterNames();     for (int i = 0; i < names.length; i++) {         map.put(names[i], values[i]);     } }
