In the article posted yesterday, many netizens sent private messages, and they couldn't control themselves. They kept reading the vibrato for a long time. This reminds me of He Jiong’s words: “If you want to get you, you have to learn to give, to give and persevere; if you really find it difficult, then you give up, if you give up, don’t complain. Life is In this way, the world is balanced. Everyone decides what his life looks like through his own efforts. Only by working hard, persevering and paying, can you get the life you want. Either shake hands with your mediocrity, or just Let your efforts be worthy of your dreams."

What are the benefits of using SpringBoot starter?
Answer: Dependency management is a vital part of all projects. When a project becomes quite complex, managing dependencies can become a nightmare because there are too many artifacts involved.
At this time SpringBoot starter comes in handy. Each statuser is playing the role of a one-stop shop that provides the Spring features we need. Other required dependencies are injected and managed in a consistent manner.
All starters belong to the org.springframework.boot group, and they all have names beginning with spring-boot-starter-. This naming method makes it easier for us to find starter dependencies, especially when we use those IDEs that support finding dependencies by name.
SpringBoot provides a lot of starters, of which the most commonly used are:
