1.工程结构图

2.maven依赖

3.AopTest controller 类

　　

@RestController
public class AopTest {

@RequestMapping (value = "/aoptest")
public String aopTest(){
return " AOP test success!";
}

}

4.定义aop类 ，切点，前置通知before，后置通知after，返回通知AfterReturning

@Aspect
@Component
public class HttpAspect {
//使用org.slf4j.Logger,这是Spring实现日志的方法
private final static Logger logger = LoggerFactory.getLogger(HttpAspect.class);

/**
 * 定义AOP扫描路径
 * 第一个注解只扫描aopTest方法
 */
//@Pointcut("execution(public * com.aston.reader.controller.StudentController.aopTest())")
///aop-test/src/main/java/com/test/controller/AopTest.java
@Pointcut("execution(public * com.test.controller.AopTest.aopTest())")
public void log(){}

/**
 * 记录HTTP请求开始时的日志
 */
@Before("log()")
public void doBefore(JoinPoint joinPoint){
    ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
    HttpServletRequest request = attributes.getRequest();
    //URL
    logger.info("url={}", request.getRequestURI());
    //method
    logger.info("method={}", request.getMethod());
    //ip
    logger.info("ip={}",request.getRemoteAddr());
    //类方法
    logger.info("class={} and method name = {}",joinPoint.getSignature().getDeclaringTypeName(),joinPoint.getSignature().getName());
    //参数
    logger.info("参数={}",joinPoint.getArgs());
}

/**
 * 记录HTTP请求结束时的日志
 */
@After("log()")
public void doAfter(){
    ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
    HttpServletRequest request = attributes.getRequest();
    logger.info("url = {} end of execution", request.getRequestURL());
}

/**
 * 获取返回内容
 * @param object
 */
@AfterReturning(returning = "object",pointcut = "log()")
public void doAfterReturn(Object object){
    logger.info("response={}",object.toString());
}
}

5.启动，输入请求http://localhost:8080/aoptest
