springboot如何连接mysql数据库

Springboot连接MySQL数据库的步骤如下:
1.在pom.xml中添加MySQL依赖
```
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
```
2.application.properties中配置MySQL相关信息
```
spring.datasource.url=jdbc:mysql://localhost:3306/databaseName?useSSL=false&characterEncoding=utf-8
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
```
其中,url中的databaseName需要替换为你自己的数据库名称。
3.在代码中定义JdbcTemplate对象连接MySQL数据库
```
@Autowired
private JdbcTemplate jdbcTemplate;
```
通过以上三个步骤即可实现Springboot连接MySQL数据库。

springboot连接mysql数据库
要在 Spring Boot 中连接 MySQL 数据库,首先需要在项目的 pom.xml 文件中添加 MySQL 的驱动依赖:
```
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.22</version>
</dependency>
```
然后在 application.properties 或 application.yml 中添加数据库连接配置信息,如:
```
spring.datasource.url=jdbc:mysql://localhost:3306/database-name
spring.datasource.username=root
spring.datasource.password=password
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
```
最后,在项目的启动类中添加 @EnableAutoConfiguration 或 @SpringBootApplication 注解,开启自动配置。
这样就可以在项目中使用 Spring Data JPA 进行数据库操作了。
如何用SpringBoot连接MySQL数据库
首先,需要在SpringBoot项目中的pom.xml文件中添加MySQL依赖,如下所示:
```xml
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>8.0.24</version>
</dependency>
```
接下来,在application.properties文件中配置MySQL数据库连接信息,如下所示:
```
spring.datasource.url=jdbc:mysql://localhost:3306/db_name
spring.datasource.username=user_name
spring.datasource.password=password
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
```
其中,url属性中的localhost:3306为MySQL数据库的地址和端口号,db_name为数据库名称,username和password为MySQL数据库的登录用户名和密码。
最后,在SpringBoot项目中使用JdbcTemplate或者Spring Data JPA进行数据库操作即可。
