后台利用aop注解的方式防止重复提交

1.建立标签:防止重复提交

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
public @interface AvoidDuplicate {
}

2.建立切面，redis加锁

  @Around(value =  "@annotation(com.cloud.drore.eboos.common.annotation.AvoidDuplicate)")public Object excute(ProceedingJoinPoint joinPoint) throws Throwable{try {Object result = null;Object[] args = joinPoint.getArgs();//redis加锁result =  validation(joinPoint);return result;} catch (Exception e) {e.printStackTrace();return ResultMessage.error(8300,"请不要重复提交！！");}}

3.方法执行之后进行解锁

  public Object validation(ProceedingJoinPoint  joinPoint) throws Throwable {String cachekey =  getCacheKey(joinPoint.toLongString(),joinPoint.getArgs());//redis加锁boolean lock =  jedisUtils.tryGetDistributedLock(PARAM_TOKEN_FLAG+cachekey, cachekey, 60000);if(lock){//加锁成功//执行方法Object funcResult = joinPoint.proceed();//方法执行完之后进行解锁jedisUtils.releaseDistributedLock(PARAM_TOKEN_FLAG +  cachekey, cachekey);return funcResult;}else{//锁已存在return ResultMessage.error(8300,"请不要重复提交！！");}}

4.加锁和释放锁

package com.cloud.drore.eboos.common.util;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;import java.util.Collections;/*** ** @Description: <br>* @Project: eboos <br>* @CreateDate: Created in 2018/4/18 14:18 <br>* @Author: */

5.用到的工具类

 private String getCacheKey(String targetName, Object[] arguments) {StringBuffer sb = new StringBuffer();UserInfo userInfo = LocalData.getCurrentUser();if(userInfo!=null)sb.append(userInfo.getId()+PARAM_LINE+LocalData.getCurrentUser().getUsername()).append(PARAM_POINT);sb.append(targetName);if ((arguments != null) && (arguments.length != 0)) {for (int i = 0; i < arguments.length; i++) {// 处理空指针 基本数据类型sb.append(PARAM_POINT).append(arguments[i] == null ? "" : getValue(arguments[i]));}}return Codec.encodeMd5(sb.toString());}public String getValue(Object obj) {if (obj.getClass().isArray()) {StringBuffer buf = new StringBuffer();Object[] array = (Object[]) obj;for (Object value : array) {if (value != null) {buf.append(value.toString()).append(",");}}return buf.toString();}return JSONObject.toJSONString(obj);}
