Spring Boot 和 H2 - 控制檯

如前一章 應用程式設定 中所述，我們在 spring boot 專案中建立了所需檔案。現在讓我們來更新位於 **src/main/resources** 和 **pom.xml** 中的 **application.properties** 和 **pom.xml**，以使用版本不同的 **maven-resources-plugin**。

application.properties

spring.datasource.url=jdbc:h2:mem:testdb

pom.xml

...
<build>
   <plugins>
      <plugin>
         <groupId>org.springframework.boot</groupId>
         <artifactId>spring-boot-maven-plugin</artifactId>
      </plugin>
      <plugin>
         <groupId>org.apache.maven.plugins</groupId>
         <artifactId>maven-resources-plugin</artifactId>
      </plugin>
   </plugins>
</build>
...

執行應用程式

在 eclipse 中，執行 **人員應用程式** 配置，該配置是在 應用程式設定 期間準備的。

Eclipse 控制檯將顯示類似的輸出。
