git上设置的
blackIP:
continueCounts: 10
timeInterval: 60
limitTimes: 5
本地注入
@Value("${blackIP.continueCounts}")
private Integer continueCounts;
@Value("${blackIP.timeInterval}")
private Integer timeInterval;
@Value("${blackIP.limitTimes}")
private Integer limitTimes;
git上空格都缩进了,也还是报错

这个相当坑爹,分布式配置是相当恶心人的,要多次尝试复制粘贴,注意空格缩进,因为每次设置我也一定会出现这个错误的。相当闹心,有时候多次复制粘贴就可以了。这个地方不做要求,知道这么使用即可。实在不行直接写死在yml中就行~~~
