一、controller方法加切面，记录操作日志

其他应用：记录方法耗时 [ljheee/my-monitor-aop (github.com)][ljheee_my-monitor-aop _github.com]

1.pom文件

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-aop</artifactId>
    </dependency>
    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjweaver</artifactId>
        <version>1.9.4</version>
    </dependency>

2.注解类

@Target({ElementType.METHOD})
    @Retention(RetentionPolicy.RUNTIME)
    public @interface LogAnno {
        String Type();
    }

3.切面类

package com.vince.aop;
    
    import com.vince.annotation.LogAnno;
    import lombok.extern.slf4j.Slf4j;
    import org.aspectj.lang.ProceedingJoinPoint;
    import org.aspectj.lang.annotation.Around;
    import org.aspectj.lang.annotation.Pointcut;
    import org.aspectj.lang.reflect.MethodSignature;
    import org.springframework.stereotype.Component;
    import org.aspectj.lang.annotation.Aspect;
    
    import java.lang.reflect.Method;
    
    /**
     * @author duanxiaoqiu
     * @Date 2019-12-03 09:52
     **/
    @Slf4j
    @Component
    @Aspect
    public class LogAopAspect {
    
        //表示匹配带有自定义注解的方法
        @Pointcut("@annotation(com.vince.annotation.LogAnno)")
        public void pointcut() {}
    
        @Around("pointcut()")
        public Object around(ProceedingJoinPoint point) {
            Object result =null;
            long beginTime = System.currentTimeMillis();
            try {
                log.info("我在目标方法之前执行！");
                result = point.proceed();
                long endTime = System.currentTimeMillis();
                MethodSignature methodSignature = (MethodSignature) point.getSignature();
                // 获取方法
                Method method = methodSignature.getMethod();
                // 获取方法上面的注解
                LogAnno logAnno = method.getAnnotation(LogAnno.class);
                // 获取操作描述的属性值
                String operateType = logAnno.Type();
                log.info("我在目标方法之后执行！");
            } catch (Throwable e) {
                // TODO Auto-generated catch block
            }
            return result;
        }
    }

4.应用

@LogAnno(Type = "添加用户")
    @RequestMapping("/")
    @ResponseBody
    public String index() {
        log.info("=======1=======" + userName);
        return "hello world";
    }

二、在controller上加切面

package com.vince.aop;
    
    import lombok.extern.slf4j.Slf4j;
    import org.aspectj.lang.ProceedingJoinPoint;
    import org.aspectj.lang.annotation.Around;
    import org.aspectj.lang.annotation.Aspect;
    import org.aspectj.lang.annotation.Pointcut;
    import org.springframework.stereotype.Component;
    
    /**
     * @author duanxiaoqiu
     * @Date 2019-12-03 10:12
     **/
    @Slf4j
    @Aspect
    @Component
    public class LogAspect {
    
        /**
         * Pointcut定义切点
         * public修饰符的   返回值任意  com.vince.controller包下面的任意类的任意方法任意参数
         */
        @Pointcut("execution(public * com.vince.controller.*.*(..))")
        public void log(){
    
        }
    
        @Around("log()")
        public Object around(ProceedingJoinPoint joinPoint) {
            Object result =null;
            long beginTime = System.currentTimeMillis();
            try {
                log.info("我在目标方法之前执行！");
                log.info("class.method: " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
                log.info("args: "+joinPoint.getArgs());
                result = joinPoint.proceed();
                log.info("我在目标方法之后执行！");
            } catch (Throwable e) {
                // TODO Auto-generated catch block
            }
            return result;
        }
    
        /*@Before("log()")
        public void doBefore(JoinPoint joinPoint){
            log.info("方法执行前...");
    
            log.info("class.method: " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
            log.info("args: "+joinPoint.getArgs());
        }
    
        @After("log()")
        public void doAfter(JoinPoint joinPoint){
            log.info("方法执行后...");
        }
    
        @AfterReturning(returning="result", pointcut="log()")
        public void doAfterReturnint(Object result){
            log.info("方法返回值：" + result);
        }*/
    
    }
