## demo项目用于模拟高并发访问controller中的方法

### 1. 测试方法

#### 1.1 运行`DemoApplication`的`main`方法启动应用

#### 1.2 浏览器访问以下地址

```java
http://localhost:8080/query?uid=helloScott
```

#### 1.3 运行`DemoApplicationTests`的`test_benchmark`方法

> 主要用于模拟nThreads=2000个线程同时并发压测`query`接口，查看uid是否能正常传入

#### 1.4 查看服务端成功调用次数,浏览器访问

```
# 用于查看调用次数
http://localhost:8080/getCount

# 用于重置调用次数
http://localhost:8080/clean
```


### 最后结果

服务端日志正常输出

```
