Answer 1

您应该从 url 中删除空间并定义方案http或https

Answer 2

如果您使用 localhost，则像这样传递 url - http://localhost:8080/api/notes定义方案很重要（http/https）也不要使用空间。

Answer 3

While we are using any services which are running on our local machines, please try to call the service by using the http protocal instead of directly calling the service. Example: localhost:1234/hello(wrong will give the above exception) http://localhost:1234/hello(correct way)

Answer 4

确保 URL、 http:// 或 https:// 中没有拼写错误

Answer 5

不要在像这样在属性文件中定义 URL 时输入 "：dev.baseURL=http://localhost:8080/products/

Answer 6

Make sure you do not forget the // in http://

Answer 7

remove space in the url at the starting point
