Springboot+mybatis+mysql creating a simple Web background project

The first step: building a framework

New enter this page

New name, first time can default, then next

Step Three: Select dependencies

Fourth step: Create a new project name and store the project path (you can create a new folder to store)

Click Finish, the first time you create a springboot download dependency will be slow, patience wait a while, download the dependency on it.

Fifth Step: Resources--application.properties write connection MySQL database load, on the data, afraid you write wrong, copy down to modify for their own database and port number on the line

#数据库加载
Spring.datasource.url=jdbc:mysql://localhost:3306/sbm?characterencoding=utf-8&useunicode=true
Spring.datasource.username=root
spring.datasource.password=lj1234
Spring.datasource.driverclassname=com.mysql.jdbc.driver

#页面热加载
Spring.thymeleaf.cache=false

#端口
server.port=6050

The sixth step: Pom.xml dependent, are springboot automatically generate download dependencies, because we are now doing a simple project operation, the following to add other dependencies will be written later, the most important is that these several dependencies

<?xml version= "1.0" encoding= "UTF-8"?>

Seventh Step: Build a Package

Then create the class

1. Entity classes (Alt+insert can quickly build get and SET with the ToString () method)

2. Create mapper, which is a interface

3. Business Layer

4 Implementation Contorller

Build Database

Start the service, the page that appears is right

And then it succeeds, calling the method implementation
