deployment environments. For example, we have a staging environment and a production environment, and the configuration for each environment will be different. Each configuration service will be hosted by a separate git repository for the environment. No other environment has access to this configuration repository, it simply provides the configuration service running in that environment.Manuscripts: Diligent Learning qkxue.netRead the full version o

So you spend a lot of time looking for it, and finally find out that there is a problem with a parameter or a comma, or the system kernel version is inconsistent, or you don't understand why! You can only switch to another server, so using Docker is a perfect escape from these pits.All right, no more nonsense, let's get started!Spring Boot

Rather than writing logic or code, developers simply add tag attributes to the template. Next, these tag properties perform pre-established logic on the DOM (Document Object model).Sample Template:You can see that thymeleaf is mainly attributed to the HTML tag, the browser when parsing the HTML, when the detection of the att
