## 二、超卖现象 ##

### 1、基于Synchronized锁解决超卖问题 ###

#### 1.1 方法锁 ####

#### 1.2 块锁 ####

### 2、基于ReentrantLock锁解决超卖问题 ###

### 3、单体应用锁的局限性 ###

## 三、分布式锁 ##

### 1、基于数据库的分布式锁 ###

### 2、基于redis实现分布式锁（客户端Redisson） ###

#### 2.1 redis分布式锁原理 ####

#### 2.2 基于分布式锁解决定时任务重复问题 ####

#### 2.3 Springboot引入redisson ####

### 3、基于zookeeper分布式锁（客户端Curator） ###

## 四、分布式锁的对比、选择 ##
