解决项目中的问题。

一

在发起请求时，浏览器自动在前面加了https，但是由于域名没有ssl认证，所以会报这个错误，去掉https中的’s’就好了。

二

因为是加了拦截器后才反生这样情况，应该是拦截器没有能够成功加载资源文件

原拦截器在config/MvcConfig中：

@Configuration
public class MvcConfig extends WebMvcConfigurationSupport {
 
}

解决办法如下

@Configuration
public class MyMvcConfig extends WebMvcConfigurerAdapter {
 
}

但WebMvcConfigurerAdapter在springboot2.0之后已经被抛弃，所以改为spring boot官方推荐的这个接口：

@Configuration
public class MyMvcConfig implements WebMvcConfigurer {
 
}

三

1	ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

服务器重启之后mysql出现问题，重启服务器。
