一、创建SpringBoot项目

1. 打开idea File->New->Project

2. 选择Spring initializr(初始化) ，然后点Next

3. 更改Group和Artifact后，点击Next

4. 在新页面中Core中勾选DevTools;Web中勾选Web；Template Engines(模板引擎)勾选 Thymeleaf；SQL中勾选JPA和              MYSQL,然后点Next

5. 最后界面直接点Finish

二、配置SpringBoot项目

1. 在src/main/java 建立以下目录

2. 编辑pom.xml文件 

pom.xml :

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.example</groupId>

            </plugin>
        </plugins>
    </build>

</project>

3. 编辑src/main/resources/ 下的 application.properties文件

application.properties：

#数据源配置
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/stu?useSSL=false&useUnicode=true&characterEncoding=utf-8&autoReconnect=true&serverTimezone=Asia/Shanghai
spring.datasource.username=root
spring.datasource.password=root    
spring.datasource.initialSize=20
spring.datasource.minIdle=50
spring.datasource.maxActive=500


#上下文配置
server.port=8888
server.servlet.context-path=/kude


#配置jpa
#帮我们自动生成表结构
spring.jpa.properties.hibernate.hbm2ddl.auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.show-sql= true

spring.jpa.properties.hibernate.enable_lazy_load_no_trans=true

4. 此时点击运行测试SpringBoot运行成功

项目搭建和配置完成，接下来编写后台代码，功能实现后再进行测试，请看下一篇：《从零开始完成一个SpringBoot+JPA的Web案例((二)后端实现)》
