</dependency>
<dependency>

<dependency>

```

## redis

```
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-data-redis</artifactId>
  <version>2.7.0</version>
</dependency>
```

## application.yml

```
spring:
  mvc:
    pathmatch:
       matching-strategy: ant_path_matcher #2.7.0默认的路径匹配改了
```

## ConfigurationProperties(prefix= "这里不支持驼峰"

比如：
```
client-pay:
  wechatPay:
    id: 1234
```

ConfigurationProperties(prefix="client-pay.wechatPay") //这里报错

需要改成：

ConfigurationProperties(prefix="client-pay.wechat-pay")
