步驟如下： **1. 創建一個SpringBoot項目** ```xml <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>1.1.23</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.13</version> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.16</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> </dependency> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <version>1.18.24</version> </dependency> </dependencies> ``` **2. `resources/application.yml`** ```yml spring: datasource: url: jdbc:mysql://localhost:3306/springdatajpa?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai username: root password: uhg</flEt3dff driver-class-name: com.mysql.cj.jdbc.Driver type: com.alibaba.druid.pool.DruidDataSource jpa: #使用mysql數據庫 database: mysql #數據庫引擎為InnoDB database-platform: org.hibernate.dialect.MySQL5InnoDBDialect #控制臺輸出正在執行的SQL語句 show-sql: true hibernate: #create：每次運行程序時，都會重新創建表，故而數據會丟失 #create-drop：每次運行程序時會先創建表結構，然后待程序結束時清空表 #upadte：每次運行程序，沒有表時會創建表，如果對象發生改變會更新表結構，原有數據不會清空，只會更新（推薦使用） #validate：運行程序會校驗數據與數據庫的字段類型是否相同，字段不同會報錯 #none: 禁用DDL處理 ddl-auto: update ``` **3. 環境搭建完成**
