SpringBoot如何使用H2嵌入式數(shù)據(jù)庫

小編給大家分享一下SpringBoot如何使用H2嵌入式數(shù)據(jù)庫，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！

1、添加maven依賴

<dependency>
	<groupId>com.h3database</groupId>
	<artifactId>h3</artifactId>
	<!-- <version>1.4.200</version>-->
</dependency>

2、添加配置信息到application.properties

spring.datasource.driverClassName=org.h3.Driver
#連接信息數(shù)據(jù)庫文件保存位置（嵌入式）
#~表示當(dāng)前用戶目錄C:\Users\Administrator
#spring.datasource.url=jdbc:h3:~/test;MODE=MYSQL
spring.datasource.url=jdbc:h3:E:/h4/test;MODE=MYSQL
#spring.datasource.url=jdbc:h3:file:./dbconfig/test;MODE=MYSQL
spring.datasource.username=root
spring.datasource.password=root
#是否開啟控制臺
spring.h3.console.enabled=true
#控制臺路徑
spring.h3.console.path=/h3

3、啟動

2021-10-30 19:51:50.011  INFO 5952 --- [           main] o.s.b.a.h3.H2ConsoleAutoConfiguration    : H2 console available at '/h3'. Database available at 'jdbc:h3:E:/h4/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)

這時候會看到文件的生成

 .mv是數(shù)據(jù)文件 .trace是日志文件

我們可以打開瀏覽器 http://localhost/h3/ 

 4、集成項目打包

修改連接路徑

#./dbconfig/test 當(dāng)前項目路徑下dbconfig文件夾下的test數(shù)據(jù)庫
spring.datasource.url=jdbc:h3: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>					
                    <!-- 復(fù)制dbconfig到打包目錄-->
                    <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>

 然后就可以運行了
