(Students who have Java foundation, have studied spring, spring MVC and mybatis framework, and have done simple projects or above can learn. However, this does not mean that this course is an introductory course. For students with development experience, the Internet of things industry is a sunrise industry, which can also be said to be the blue ocean of development in the next decade. Then I believe that an industry supported by the real economy will never have such a big bubble in the Internet industry, and it will never leave your job without protection. This course is also very suitable for students who are interested in Internet of things and want to improve themselves in an all-round way.)
