The following error is reported when reading configuration @ Value reading configuration file parameters:

Found a lot of posts on the Internet, there are probably three solutions: 1.maven first clean and then install; (my useless) 2. Change aplication.yml to alication.properties. Add a bean function @ Bean public static PropertySourcesPlaceholderConfigurer placeholderConfigurer () {xxxxxxxxxx (this method, the project can be started, but the parameters are still not read)

So my problem is not these three problems. Later, I carefully studied the configuration. Why can I get the appkey of baidu, but not aliyun? finally, I found that the colon was written as a Chinese full-width colon, because the yml format requires that there must be a space after the colon, and the half-width colon + space is exactly the same length as the full-width colon, so I can't find the problem for almost a week. Later, I think about how to avoid this happening later, it is too difficult to find, and then I looked at it, in fact, idea has a color hint on the yml file format, full-width colon and half-width colon color is not the same, just because I changed the interface style of edit idea into a white style, the color prompt is not very obvious.
