AOP 實現用戶操作記錄和防止重複提交

1：記錄用戶操作記錄

   實現思路： 利用aop，可以攔截每個用戶調用的滅個接口，將每個接口的名稱，用戶ip  用戶名記錄下來

   1.1：定義切點

 

  private RedisDao redisDao;
    @Pointcut("execution(* kainian.wu.demoweb.controller.*.*(..))")
    public void pointCkeck(){}

1.2：獲取操作數據，將數據存入數據

   @Before("pointCkeck()")
    public void beforeSleep(JoinPoint joinPoint) throws CMSException {
        //1：方式名稱
        String methodName = joinPoint.getSignature().getName();
        System.out.println("方式名"+methodName);
        //2:\


        String reqParam = "";
        String reqParam21 = "";
        String[] reqParam1 = null;
        String[] reqParam2 = null;
        Signature signature = joinPoint.getSignature();
        MethodSignature methodSignature = (MethodSignature) signature;
        Method targetMethod = methodSignature.getMethod();
        Annotation[] annotations = targetMethod.getAnnotations();
        for (Annotation annotation : annotations) {
            //此處可以改成自定義的註解
            if (annotation.annotationType().equals(NoRepeatSubmit.class)) {
                NoRepeatSubmit apiOperation4 = (NoRepeatSubmit) annotation;
                reqParam21 = apiOperation4.vaue();
                continue;
            }
            
            if (annotation.annotationType().equals(ApiOperation.class)) {
                ApiOperation apiOperation = (ApiOperation) annotation;
                reqParam = apiOperation.value();
                continue;
            }
            
            if (annotation.annotationType().equals(GetMapping.class)) {
                GetMapping getMapping = (GetMapping) annotation;
                reqParam1 = getMapping.value();
                continue;
            }
            
            if (annotation.annotationType().equals(PostMapping.class)) {
                PostMapping getMapping = (PostMapping) annotation;
                reqParam2 = getMapping.value();
                continue;
            }
        }
        System.out.println("攔截的註解的參數：");
        System.out.println("方法名稱"+reqParam);
        //3:接口路徑
        System.out.println("方法路徑"+JSON.toJSON(reqParam1));
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();

        // 當前IP地址
        String ipAddr = getRemoteHost(request);
        System.out.println("IP地址"+ipAddr);
        String url = request.getRequestURL().toString();
        log.info("請求URL{}:",url);



        //4；參數
        List<Object> args1 =  Arrays.asList( joinPoint.getArgs() ) ;
        User user =  JSONObject.parseObject(JSONObject.toJSONString(args1.get(0)), User.class);
        System.out.println("參數!"+user);
        System.out.println(user.getName());
        if(user.getName().equals("dd")) {
           throw new CMSException("1","攔截") ;
        }
    }

 

 

        /**
         * 獲取目標主機的ip
         * @param request
         * @return
         */
        private String getRemoteHost(HttpServletRequest request) {
            String ip = request.getHeader("x-forwarded-for");
            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
                ip = request.getHeader("Proxy-Client-IP");
            }
            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
                ip = request.getHeader("WL-Proxy-Client-IP");
            }
            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {
                ip = request.getRemoteAddr();
            }
            return "0:0:0:0:0:0:0:1".equals(ip) ? "127.0.0.1" : ip;
        }

2：限制接口的調用次數，防止重複提交

實現思路：單一的直接通過token限制某個用戶的接口調用次數是有問題，可以通過自定義註解去指定需要限制的接口

2.1: 自定義註解類

package kainian.wu.demoweb.advice;

import java.lang.annotation.*;

/**
 * * *  GOOK LUCK  * *
 *
 * @Author by   wukainian,
 * @Date on     2019/8/28.
 */

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface NoRepeatSubmit {
    String notes();
    String vaue();
}

 

2.2：限制含有該註解的接口調用次數

/**
 *
 */
@RestController
@RequestMapping(value = "user")
@Api(value = "DemoController",tags =  "用戶控制類響應結果")
@SuppressWarnings("unchecked")
public class UserController {

    Logger logger = LoggerFactory.getLogger( UserService.class );

    @Autowired
    private UserService userService;

    /**
     * 查詢用戶列表
     * @return
     */

    @NoRepeatSubmit(notes = "REPEAT",vaue = "防止重複提交")
    @ApiOperation(value = "查詢用戶列表", notes = "List類型")
    @PostMapping(value = "/all")
    @ResponseBody
    public ClientResponse list(@Validated @RequestBody User user)  {

        return ClientResponse.ok(userService.findAll( 1L ));
    }

 

2.3：測試

    @Before("pointCkeck()")
    public void beforeSleep(JoinPoint joinPoint) throws CMSException {
        //1：方式名稱
        String methodName = joinPoint.getSignature().getName();
        System.out.println("方式名"+methodName);
        //2:\


        String reqParam = "";
        String reqParam21 = "";
        String[] reqParam1 = null;
        String[] reqParam2 = null;
        Signature signature = joinPoint.getSignature();
        MethodSignature methodSignature = (MethodSignature) signature;
        Method targetMethod = methodSignature.getMethod();
        Annotation[] annotations = targetMethod.getAnnotations();
        for (Annotation annotation : annotations) {
            //此處可以改成自定義的註解
            if (annotation.annotationType().equals(NoRepeatSubmit.class)) {
                NoRepeatSubmit apiOperation4 = (NoRepeatSubmit) annotation;
                reqParam21 = apiOperation4.vaue();
                continue;
            }

            if (annotation.annotationType().equals(ApiOperation.class)) {
                ApiOperation apiOperation = (ApiOperation) annotation;
                reqParam = apiOperation.value();
                continue;
            }

            if (annotation.annotationType().equals(GetMapping.class)) {
                GetMapping getMapping = (GetMapping) annotation;
                reqParam1 = getMapping.value();
                continue;
            }

            if (annotation.annotationType().equals(PostMapping.class)) {
                PostMapping getMapping = (PostMapping) annotation;
                reqParam2 = getMapping.value();
                continue;
            }
        }


        if(null != reqParam21) {
            //具體可以通過時間來限制每個接口的調用
            throw new CMSException("1","攔截") ;
        }

        System.out.println("攔截的註解的參數：");
        System.out.println("方法名稱"+reqParam);
        //3:接口路徑
        System.out.println("方法路徑"+JSON.toJSON(reqParam1));
        HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();

        // 當前IP地址
        String ipAddr = getRemoteHost(request);
        System.out.println("IP地址"+ipAddr);
        String url = request.getRequestURL().toString();
        log.info("請求URL{}:",url);



        //4；參數
        List<Object> args1 =  Arrays.asList( joinPoint.getArgs() ) ;
        User user =  JSONObject.parseObject(JSONObject.toJSONString(args1.get(0)), User.class);
        System.out.println("參數!"+user);
        System.out.println(user.getName());
        if(user.getName().equals("dd")) {
           throw new CMSException("1","攔截") ;
        }
    }
