1、添加maven依赖
<dependency> <groupId>com.h2database</groupId> <artifactId>h2</artifactId> <!-- <version>1.4.200</version>--> </dependency>
2、添加配置信息到application.properties
spring.datasource.driverClassName=org.h2.Driver #连接信息数据库文件保存位置（嵌入式） #~表示当前用户目录C:\Users\Administrator #spring.datasource.url=jdbc:h2:~/test;MODE=MYSQL spring.datasource.url=jdbc:h2:E:/h3/test;MODE=MYSQL #spring.datasource.url=jdbc:h2:file:./dbconfig/test;MODE=MYSQL spring.datasource.username=root spring.datasource.password=root #是否开启控制台 spring.h2.console.enabled=true #控制台路径 spring.h2.console.path=/h2
3、启动
2021-10-30 19:51:50.011 INFO 5952 --- [ main] o.s.b.a.h2.H2ConsoleAutoConfiguration : H2 console available at '/h2'. Database available at 'jdbc:h2:E:/h3/test'
2021-10-30 19:51:50.868 INFO 5952 --- [ main] o.s.b.w.embedded.tomcat.TomcatWebServer : Tomcat started on port(s): 80 (http) with context path ''
2021-10-30 19:51:50.879 INFO 5952 --- [ main] com.example.DemoApplication : Started DemoApplication in 3.336 seconds (JVM running for 3.657)
这时候会看到文件的生成
.mv是数据文件 .trace是日志文件
我们可以打开浏览器 http://localhost/h2/
4、集成项目打包
修改连接路径
#./dbconfig/test 当前项目路径下dbconfig文件夹下的test数据库 spring.datasource.url=jdbc:h2:file:./dbconfig/test;MODE=MYSQL
打包
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
<plugin>
<artifactId>maven-resources-plugin</artifactId>
<executions>
<!-- 复制dbconfig到打包目录-->
<execution>
<id>copy-dbconfig</id>
<phase>package</phase>
<goals>
<goal>copy-resources</goal>
</goals>
<configuration>
<resources>
<resource>
<directory>dbconfig</directory>
</resource>
</resources>
<outputDirectory>${project.build.directory}/dbconfig</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
然后就可以运行了
