Controller Considerations in Spring Boot

Spring boot controller The depth of the water, after learning, I summarize some tips for later reference, reduce errors:

1.controller There are two main tags: @Controller and @restcontroller, two labels can not function at the same time, the former labeled class can only return static files, the latter labeled class for returning data types such as JSON string

2. When using the @controller tag, the file under the templates is not recognized (it has been tested, found and many other online statements are not the same), only the static folder under the file can be read directly, the specific code is as follows:

@RequestMapping (value= "/", method= requestmethod.get) public
String Home () {
    return "views/index.html";
}

Here static is accessed as the root directory.
