搭建单体SpringBoot项目 集成Mysql数据库

`

1. SpringBoot框架集成Mysql

1.1. 引入mysql maven包

 <!--集成mysql数据库-->
<dependency>
  <groupId>mysql</groupId>
  <artifactId>mysql-connector-java</artifactId>
</dependency>

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<!-- 数据库连接池 -->
<dependency>
  <groupId>com.alibaba</groupId>
  <artifactId>druid-spring-boot-starter</artifactId>
</dependency>

1.2. 添加数据库配置

druid配置请前往：Druid数据库连接池和监控

在spring boot项目的配置文件application.properties中添加如下配置：

spring.datasource.druid.url=jdbc:mysql://127.0.0.1:3306/db?useUnicode=true&characterEncoding=utf-8&useSSL=false
spring.datasource.druid.username=root
spring.datasource.druid.password=pandacode
spring.datasource.druid.max-active=20
spring.datasource.druid.initial-size=5
spring.datasource.druid.min-idle=5
spring.datasource.druid.min-evictable-idle-time-millis=300000
spring.datasource.druid.max-wait=60000
spring.datasource.druid.validation-query=select 1
spring.datasource.druid.test-on-borrow=false
spring.datasource.druid.test-on-return=false
spring.datasource.druid.test-while-idle=true
spring.datasource.druid.time-between-eviction-runs-millis=60000
