1.导入坐标

<dependency>
   <groupId>org.springframework</groupId>
   <artifactId>spring-aop</artifactId>
   <version>${spring.version}</version>
</dependency>
<dependency>
	<groupId>org.aspectj</groupId>
	<artifactId>aspectjweaver</artifactId>
	<version>1.8.13</version>
</dependency>

2.编写实体类

public class sysLog {
	private String id;
	private Date visitTime;
	private String visitTimeStr;
	private String username;
	private String ip;
	private String url;
	private Long executionTime;
	private String method;
｝

3.编写切面类

@Component
@Aspect
public class sysAop {
    private Date visitTime;
    private Class executionClass;// 访问的类
    private Method executionMethod; // 访问的方法
    @Autowired
    private HttpServletRequest request;
    @Autowired
    private sysService service;

    @Before("execution(* com.li.controller.*.*(..))")
    public void preMethod(JoinPoint jp) throws Exception{
        visitTime=new Date();
        executionClass = jp.getTarget().getClass();
        String methodName = jp.getSignature().getName();
        Object[] args = jp.getArgs();
        if(args==null || args.length==0){
            executionMethod=executionClass.getMethod(methodName);
        }else{
            ArrayList<Class> classes = new ArrayList<>();
            for (Object arg : args) {
                classes.add(arg.getClass());
            }
            Class[] argsClass = classes.toArray(new Class[classes.size()]);
            executionMethod=executionClass.getMethod(methodName,argsClass );
        }
    }

    @After("execution(* com.li.controller.*.*(..))")
    public void postMethod(){
        sysLog sysLog = new sysLog();
        Date postTime = new Date();
        Long executionTime= postTime.getTime() - (visitTime).getTime();
       if(executionClass!=null&&executionMethod!=null&&executionClass!=sysAop.class){
//        url获取
           String url="";
           RequestMapping classMapping = (RequestMapping) executionClass.getAnnotation(RequestMapping.class);
           RequestMapping methodMapping = executionMethod.getAnnotation(RequestMapping.class);
           if(classMapping!=null){
               String classUrl = classMapping.value()[0];
               String methodUrl=null;
               if(methodMapping!=null){
                   methodUrl = methodMapping.value()[0];
               }
               url=classUrl+methodUrl;
           }
//           ip获取
           String ip= request.getRemoteAddr();
//        用户名获取
           User user = (User) SecurityContextHolder.getContext().getAuthentication().getPrincipal();
           String userName = user.getUsername();

//        封装
           sysLog.setExecutionTime(executionTime);
           sysLog.setIp(ip);
           sysLog.setUrl(url);
           sysLog.setUsername(userName);
           sysLog.setVisitTime(visitTime);
           sysLog.setVisitTimeStr(visitTime.toString());
           sysLog.setMethod("[类名]" + executionClass.getName() + "[方法名]" + executionMethod.getName());
       }

//        保存
        service.save(sysLog);
    }
}
